It should be explicitly men tioned that the T3 generation seeds were not collected from exactly the same plants used here as T2 generation. Both seed generations had been collected beforehand and both generations were grown simultaneously Brefeldin A ATPase adja cent Inhibitors,Modulators,Libraries to each other in the glasshouse. Regardless, the in tensity of the methylation increase was highly reproducible and the patterns from both generations matched perfectly. Among all analyzed clones certain asymmetric positions were only methylated at very low frequencies. In particular, the cytosines at the 14th and 160th position showed, for instance, 0% methyla tion in both generations. We grouped the asymmetric CHH sites into low, medium and high meth ylated positions and found that the overall methylation preference was nucleotide specific with higher probability at certain positions compared to others.

These findings were similar to the site specific preferences of asymmetric positions found in a genome wide analysis of the epigenome in Arabidopsis. The epigenetic status of the transgene was equally inherited by parental lines Since we commonly combine phenotypes Inhibitors,Modulators,Libraries of transgenic plants by crossing, we wanted to determine whether the heredity of a silenced transgene might be parent of ori gin specific. We performed reciprocal crosses between wild type and transgenic lines and tested the hemizygous offspring for hygromycin resistance. The crosses with the silencing affected lines all showed high levels of hygromycin sensitivity, independ ent of the direction of the cross revealing equal inherit ance of the silenced allele through both female and male gametes.

The crossings with the stable expressing control lines always retained their hygromycin resistance. Although crossings had, in certain cases, the potential to reduce silencing, we did not observe a reduction compared to plants Inhibitors,Modulators,Libraries produced from self pollinations. Equivalent transgene inactivation in IR lines Unwanted transgene inactivation Inhibitors,Modulators,Libraries is not restricted to sense expression lines Inhibitors,Modulators,Libraries and has been reported frequently for inverted repeat constructs, which can also lose their in trans silencing ability. In the process of producing several hundred IR lines for the targeted si lencing of endogenous N. attenuata genes involved in plant defense against herbivores, we have observed several incidents of resistance marker loss in several IR lines over the past decade.

Most recently, this was ob served in the T3 generation Perifosine FDA of the ir ACX1 line, which normally shows a reduced ability to accumulate jasmonic acid after wounding due to the in trans silencing of the endogenous acx1 gene. Consistently with our previous observations, the T3 seedlings of ir ACX1 also lost the ability to grow on hygromycin containing media. To test the general applic ability of a cell culture induced transgene reactivation we included this IR line as a candidate for the second ary regeneration process.

Moreover, the expression of the gene encoding ��24 in E coli is

Moreover, the expression of the gene encoding ��24 in E. coli is regulated by the stringent response. The possible Afatinib order role of ��24 on the Inhibitors,Modulators,Libraries expression of gluQ rs under osmotic stress might be interesting to study. GluQ RS is an enzyme responsible for the formation of the GluQ tRNA modification, and two independent groups have shown that this enzyme required a high concentration of glutamate to be activated and transferred to the queuosine base present on the tRNAAsp. Interestingly, one of Inhibitors,Modulators,Libraries the first events to occur when bacteria are subject to high osmolyte stress is an increase in glutamate levels within the cytoplasm. Our observation indicates an important role of the tRNA modification for the growth of S. flexneri in the presence of osmolytes. Other tRNA modifications might play a similar role in this stress condition.

Inhibitors,Modulators,Libraries In E. coli, inactivation of the yfiC gene, responsible for the modification at the adenosine 37 present on the tRNAVal, leads to a high sensitivity to osmotic stress. Transcription of gluQ rs is regulated by a terminator The results obtained in the present work show the pres ence of a terminator and suggested the functionality of this structure. To our knowledge, there are few examples of bacterial genes that have simi lar structures. There is a terminator structure upstream of the DNA primase gene, dnaG, which also has an un usual Shine Dalgarno sequence. Another example is the recX gene in E. coli, where readthrough accounts for approximately 10% of its transcription.

The two characteristics of gluQ rs described Inhibitors,Modulators,Libraries in this work, co transcription with the upstream gene and the presence of a terminator immediately upstream, allow us to propose that both the transcription and translation process could be regulated in the gluQ rs gene. It has been described, that the presence of terminators up stream of the coding region might be part of a regula tory system such as a riboswitch. Inhibitors,Modulators,Libraries Riboswitches for genes involved in queuosine formation have been described, in which the precursor preQ1 is the ligand of the mRNA structure. Using the riboswitch server, we did not identify any potential riboswitch. However we can not discount that the terminator described here might be part of a regulatory circuit similar to a riboswitch, or that an unidentified protein might bind the termin ator structure.

GluQ modification and codon bias tRNA modifications present at the anticodon loop might be important Enzastaurin MM for the accuracy of codon reading during the translation processes. Morris et al, 1999 proposed, based on molecular modeling, that the tRNAAspQ34 might improve recognition of both GAC and GAU codons, consequently the interaction of the codon GAU with the anticodon of tRNAAspG34 could be less efficient. In fact, in S. flexneri there are a few genes such as sitA, virF and proX that have a bias toward those codons that favor the modified tRNA.

As shown in Figure

As shown in Figure 6B,triple immunocytochemical staining for SERT,NSF and 5 HT revealed that NSF co localizes with SERT in the cell body and fibers of cultured seroto nergic neurons.SLC6A4 and N ethylmaleimide sensitive factor expression in the raphe region of post mortem brains from autism patients The demographic characteristics of subjects are described in Tables 2 and 3.There were no significant differences in age,race,gender and PMI between the autism and control groups.Although changes in SERT function and expression have been implicated in autism,mRNA expression of the SLC6A4 gene that encodes SERT in the brains of autistic individuals has never been reported.Therefore,first,we measured SLC6A4 expression in the raphe region of post mortem brains from autistic individuals and controls using qRT PCR.

SLC6A4 Inhibitors,Modulators,Libraries expression was normalized to the expres sion levels of an internal control.As shown in Figure 7A,there are wide individual differences in the expression level of SLC6A4 among Inhibitors,Modulators,Libraries the subjects,and the level did not differ significantly between subjects with autism and controls.Then,we measured NSF expression in the same way.NSF Inhibitors,Modulators,Libraries expression was normalized to the expression of ACTB.We found that the NSF expression level in autism patients tended to be lower than that in controls,however,this trend was not statistically significant.SLC6A4 and N ethylmaleimide sensitive factor expression in lymphocytes from patients with autism spectrum disorders Inhibitors,Modulators,Libraries NSF is expressed ubiquitously in all normal human tissues including lymphocytes.Lymphocytes also carry SERT.

Thus,we measured expressions of these genes in lymphocytes from individuals with ASD and age and sex matched controls by qRT PCR.The demographic characteristics of the subjects are described in Table 4.There were no significant differences in age or IQs between the ASD and control groups.As shown in Figure 8A,the expression level of SLC6A4 did Inhibitors,Modulators,Libraries not differ significantly between subjects with ASD and controls.On the other hand,we found that the NSF expression level in ASD but the NSF expression level was significantly decreased in subjects with ASD and correlated with the severity of clinical symptoms.N ethylmaleimide sensitive factor functions and protein binding NSF is a homohexameric ATPase,which is an essential component of the protein machinery respon sible for various membrane fusion events,including intercisternal Golgi protein transport and the exocytosis of synaptic vesicles.

NSF binds to glucose metabolism soluble NSF attachment protein receptor complexes and mediates the recycling of spent SNARE complexes for subsequent rounds of membrane fusion.While this is a major function of NSF,it also interacts with patients were significantly lower than that in controls.More over,there was a significantly negative correlation between NSF expression and ADI R Domain A score,which quan tified impairment in social interaction,in individuals with ASD.

have recently reported that rapamycin, reducing Plasminogen activator inhibitor 1 1 expression, was able to decrease extracellular matrix CC5013 deposition in all renal compartments of patients with chronic allograft nephropathy. On the other hand, high concentrations of EVE, through a massive mTORC1 inhibition, may lead to a down regulation of S6K and a subsequent hyper activation of mTORC2 that, sustaining the phosphorylation of AKT at S473, could induce a feedback loop that stimulates PI3K AKT signaling activating the cellularmolecular machinery leading to renal fibrosis. In particular AKT, once activated, could induce, through the inhibition of Glycogen synthase kinase 3, the nuclear translocation of B catenin which stimulates the expression of EMT associated genes.

Our data Inhibitors,Modulators,Libraries confirmed that the knock down of AKT can control the activation of EMT program. This confirms previous results from pharmacodynamic analysis of cancer patient derived tumor material showed increased AKT S473 phosphorylation in some cases after treatment with doses and schedules of EVE defined as biologically optimal through Inhibitors,Modulators,Libraries pharmacokineticpharmacody namic modeling of preclinical and phase I data. Additionally, we emphasized that, as previously dem onstrated, HPSE has a pivotal role in the aforementioned pathway. In fact, the silencing of this enzyme in our cellular model reversed the activation of the EMT. Heparanase is an endo B D glucuronidase that cleaves heparan sulfate side chains at a limited number of sites, hence participates in ECM degradation and remodeling.

The degradation of several con stituents Inhibitors,Modulators,Libraries of the ECM, including heparan sulfate proteo glycans, promotes the release of growth factors such as FGF 2. Moreover, we previously shown that HPSE is necessary to sustain the PI3KAKT pathway mediated by FGF 2 which induces the expression of mesenchymal markers SMA Inhibitors,Modulators,Libraries and Vimentin, leads to degrad ation of the basement membrane by means of the secre tion of matrix metalloproteinases and increases cell motility. The heparanase expression is finely reg ulated by transcription factor, DNA methylation and vari ous endogenous molecules. Finally in order to find new elements involved in EVE induced EMT, we analyzed the differences in the tran scriptomic profile between HK 2 EVE treated cells and controls. Our study was performed using a microarray technology able to evaluate simultan eously the expression of more than 30,000 genes.

Inhibitors,Modulators,Libraries How ever, to take together full advantage of the opportunities offered by this high throughput method, it is necessary to manage, integrate and interpret a huge amount of data correctly. Thus, we decided to use a pathway analysis to focus our research on candidate genes known to be associated with EMT in order to reduce the false positive rate and the puzzling factors not directly associated with the aims of our research. Different statistical algorithms identified two genes significantly up regulated by this drug.

05 was considered to be statistically significant. Lay abstract Inhalation of infectious aerosols containing viable Myco bacterium tuberculosis, results in symptomatic tuberculosis in about 5 10% of people, while the majority of exposed individuals develop asymptom atic, latent TB infection. These diverse clinical outcomes following Mtb infection are determined by intricate host pathogen Nutlin-3a IC50 interactions that are not fully understood. We have established a rabbit model of pul monary TB that closely mimics the pathological features of human disease and LTBI. In our model, pulmonary infection of rabbits with Mtb HN878, a hyper virulent W Beijing strain, results in progressive cavitary disease infection with CDC1551 is effectively cleared over time, establishing LTBI that can be reactivated upon immune suppression.

In the present study, we used our rabbit model to test the hypothesis Inhibitors,Modulators,Libraries that the initial host response in the lungs within hours of infection determines later outcome. At similar infection doses, we found increased accumulation of macrophages and PMN in the lungs of HN878, compared to CDC1551 infected rabbits, at 3 hours. Consistently, we observed activation of cellular networks involved in the inflammatory response, STAT1 activation, recruitment and activation of macrophages and PMN, and fMLP stimulation in the lungs of HN878 infected rabbits. Similar differential expression patterns in all the tested network genes were seen at 4 weeks, with infection and pathology reduced in CDC1551 infected animals compared to HN878 infection.

This suggested that the overall outcome Inhibitors,Modulators,Libraries following Mtb infection of rabbit lungs is significantly influenced by the differential regula Inhibitors,Modulators,Libraries tion of inflammation associated innate immune cells and associated gene expression changes observed already at 3 hours. Background In humans, inhalation of aerosol droplets containing Mtb results in a spectrum of clinical outcomes, ranging from progressive granulomatous disease, with continued bacil lary growth and exacerbated lung pathology, to contain ment of infection and establishment of asymptomatic latent infection. The deter minants of outcome following Mtb infection have been shown to be dependent Inhibitors,Modulators,Libraries on the host innate immune re sponse. Polymorphisms in genes encoding the toll like receptors, vitamin Inhibitors,Modulators,Libraries D receptors, and other innate immune recognition molecules have been associated with increased susceptibility of individuals to TB disease.

In addition, recent studies have suggested that the nature of the infecting bacilli also contributes to the outcome of infection. Epidemio logical studies have shown differential infectivity among various Mtb strains in the population. biological activity Genotypic analysis of 516 clinical isolates from patients showed that Mtb strains of the W Beijing lineage caused the highest num ber of TB cases in Taiwan. Similarly, a strong as sociation between W Beijing and HIV infection was reported among South African patients.

CRP levels and higher neutrophils in this group were also negativ

CRP levels and higher neutrophils in this group were also negatively correlated with the domain score inhibitor Lapatinib Learning Memory. In the VEGFR TKI patients higher ESR, CRP and LDH levels were associated with higher scores on the BDI II, indicating more depressive symptoms. No correlations were found between the free testosterone or estradiol levels and the results on the neuropsychological tests or the self report questionnaires. In both patient groups, the VEGF levels were not asso ciated with the results on the cognitive domain scores or fatigue. Only in the patient control group higher VEGF levels were associated with less complaints on mood, psychological well being and cognitive failure in daily functioning. We were able to analyze serum cytokine levels in 29 VEGFR TKI patients and 18 patient controls.

In both groups no detectable Inhibitors,Modulators,Libraries levels of IL 5 and IL 6 were found in any of the patients, and IL 2 and TNF levels were only sporadically detected. The IL 8 level was detectable in 80% of the VEGFR TKI group and in 67% of the patient controls and no difference was found in IL 8 levels between the patient groups. We found no correlations between the serum IL 8 level and the scores on the neuropsychological tests or the self report questionnaires. No correlations were found between the duration of treatment with VEGFR TKI and biomarker concentrations or the results of the neuropsychological tests and the self report questionnaires, except for the results on the subdomain Working Memory and the CIS20r.

Discussion This study is the first to examine cognitive functioning and subjective cognitive complaints in cancer patients during treatment with the VEGFR TKI sunitinib or sora fenib. Inhibitors,Modulators,Libraries We found that these patients performed worse on the cognitive domains Learning Memory and Executive Functions compared to healthy controls. Furthermore, a longer duration Inhibitors,Modulators,Libraries of VEGFR TKI treatment was associated with worse functioning on Work ing Memory tasks. Patient controls also Inhibitors,Modulators,Libraries showed impair ments on the neuropsychological tests concerning Learning Memory. However, in contrast with the VEGFR TKI patients, they showed im pairment only on the subdomain Problem Solving but not on Response Generation. Our data suggest that effect sizes of cognitive dysfunction in patients using VEGFR TKI are larger on the domains Memory Learning and Executive Functions, compared to patient controls.

Although we found no significant differences in the results of the neuro psychological tests between the VEGFR TKI patients and the patient controls, possibly due to the smaller group Inhibitors,Modulators,Libraries size of the patient control group. Since both patient groups performed on the domain Attention Concentration the same as the healthy con trols, the observed deficits in kinase inhibitor Sorafenib the other domains are not due to worse attention and concentration.

It is believed unlikely that NO is the sole mediator of SNP induc

It is believed unlikely that NO is the sole mediator of SNP induced chondrocyte death and peroxynitrite, a reaction product of NO and superoxide anions, or the primary by products of the decomposition of SNP, such as the cyanide aninon or pentacy anoferrate complex, might contribute to its cytotoxicity. It is unclear whether chondrocyte apoptosis is the major mechanism of cartilage degradation or merely a by product of tissue degeneration. Mitochondria comprise a target of NO and there is accumulating evidence that inhibition of respiration may contribute to the pro apoptotic effect of NO by m alteration, transition pore opening and release of cyto chrome c. There is increasing evidence about the importance of mitochondria in OA pathology.

Pre viously, we showed that the activity of the mitochondrial complexes II and III is lower in OA than in normal human chondrocytes, this produces a decrease in ATP levels as well as a higher ROS generation. The relevance of the MRC inhibition in human Inhibitors,Modulators,Libraries chondrocytes is already known, the inhibition of complexes III and V of the MRC induces an inflammatory response, which could be especially relevant in relation to prostaglandin E2 production via mitochondrial Ca2 exchange, ROS production, and nuclear factor B activation. More recently, Rego and collaborators have found that the predisposition to the development of OA is related to some haplogroups Inhibitors,Modulators,Libraries of mitochondrial Inhibitors,Modulators,Libraries respira tory genes of chondrocytes. Also, chondrocytes are not the only joint cells affected Inhibitors,Modulators,Libraries in OA pathology and, a recent study has shown that SNP reduces the survival of OA synoviocytes by regulating mitochondrial functional ity, as well as the proteins controlling the cell cycle.

Analysis of the MRC showed that at 5 hours, SNP reduced the activity of complex IV by 30%, furthermore, SNP induced depolarisation of the mitochondrial mem brane. In this study we show that NOC 12 induces depolarisation of the mitochondrial membrane as well as SNP, but to a lesser extent, however, it had a more radical effect Inhibitors,Modulators,Libraries on MRC activity than SNP, this donor reduces the activities of all the complexes except complex II. These results show that the inhibition selleck inhibitor of the MRC complexes is not the main cause of cell death induction in chondrocytes by NO. On the other hand, CS activity was increased about 40% in NOC 12 treated chondrocytes, and this fact has been correlated with an increment of the mito chondrial mass, Nisoli and collaborators also suggested that NO is implicated in the regulation of energy metabo lism, possibly through the enhancement of mitochondria formation. Similar findings were previously found in OA chondrocytes but not in SNP treated ones.

However, its min

However, its min Bicalutamide IC50 eralisation was retarded, as most trabeculae remained cov ered with a thick layer of osteoid. In addition, trabeculae within the cortical regions appeared scarcer and Inhibitors,Modulators,Libraries the cartilaginous and fibrotic tissues persisted. Quantitative CT analysis revealed a 75% reduction of Inhibitors,Modulators,Libraries BV TV in the cortical regions as well as slight decrease in the average BV TV in the bone marrow cavity when compared with the control group. This appears not to be due to a scarcity of osteoblasts, as judged by the presence of the collagen type I expressing cells. The intense expression of Osteopontin, known to demarcate terminally hyper trophic chondrocytes and early osteoblasts, argues for an impairment of the maturation process. Oste opontin is known to facilitate osteoclast mediated bone resorption.

We thus quantified TRAP positive bone lining cells within Inhibitors,Modulators,Libraries the injury site and determined the rate of bone turnover by measuring D PYD concentrations in serum. Osteoclast numbers were increased in the injury site in Nf1Prx1 mice when compared with controls and lovastatin treatment did not significantly Inhibitors,Modulators,Libraries change this. This was paralleled by an increased serum D PYD in Nf1Prx1 animals, which was only slightly reduced by lovastatin treatment. Day 28 post injury The injury site became difficult to locate in the control animals, demonstrating the speed and efficacy of the regeneration processes. Solid bone, undistinguishable from the surrounding cortical bone, replaced initially formed woven bone. In the Nf1Prx1 animals the injury site was also closed by calcified extracellular matrix, but woven bone was still present in the marrow cavity.

Fur thermore, cortical bone Inhibitors,Modulators,Libraries was covered by a thick osteoid, indicating an ongoing abnormality of the mineralisation process. Cortical bone appeared strikingly thinned and at many sites it was penetrated by thick blood vessels. Lovastatin treatment improves injury healing in Nf1Prx1 mice Day 7 post injury Improvement of bone quality had already become obvi ous by the 7th day of treatment. In contrast to untreated mice, unmineralised bone was neither detectable in the vicinity nor distally from the injury site. Calcified trabecular bone was found in the bone mar row cavity and it became detectable also in the cortical regions, indicating accelerated osteoprogenitor differenti ation as well as normalisation of mature osteoblast func tion. The CT analysis indicated that BV TV within the bone marrow cavity was two fold higher in the lovastatin treated mice than in untreated mice and slightly exceeded the BV TV values of the control group. In contrast, in the cortical regions BV TV remained at basal level in both the lovastatin treated and untreated Nf1 deficient mice compared with the control group.

At screening, patients either had LDL C 70 mg dL with documented

At screening, patients either had LDL C 70 mg dL with documented CVD or LDL C 100 mg dL with no documented his tory of CVD. The maximum tolerated dose of statin was defined as either rosuvastatin 20 mg or 40 mg daily, atorvastatin 40 mg or 80 mg daily, or simvastatin 80 mg daily. However, patients not able to tolerate the above statin doses remained eligible Sorafenib Tosylate clinical trial for inclusion if they were on a lower dose of daily ator vastatin, rosuvastatin, or simvastatin provided that the investigator had a documented reason for not using the higher dose. Study procedures Patients meeting the inclusion criteria entered a screen ing period of up to 2 or 3 weeks prior to randomization. During screening, pa tients completed informed consent, inclusion exclusion criteria were further assessed, patient information was collected, and patients were trained in the use of the auto injector device.

In addition, vital signs were taken, a 12 lead electrocardiogram was performed, and fasting blood and urine samples were obtained for analysis. AEs will be assessed from the screening visit throughout the study. LDL C will be calculated using the Friedewald formula at screening and at all time points during the double blind treatment periods. If TGs exceed 400 mg dL then the central laboratory will reflexively measure LDL C ra ther than calculating it. LDL C will also be measured at week 0 and week 24. Other lipid parameters, including total cholesterol, HDL C, TGs, Apo B, Apo A1, and Lp, will be mea sured directly by the central laboratory.

COMBO I Eligible patients were randomized, with stratification by 1 prior history of myocar dial infarction or ischemic stroke, and 2 intensity of statin treatment, to ensure balance between arms for these factors. After randomization, patients entered a double blind treatment period of 52 weeks. In addition to existing statin and other existing LLT if appropriate, patients randomized to alirocumab received a 75 mg subcutaneous dose every 2 weeks, adminis sellckchem tered as a single 1 mL injection utilizing an auto injector, from randomization to week 12. Patients randomized to placebo received a 1 mL SC placebo injection from an identical auto injector. At week 12, patients randomized to alirocumab were up titrated to 150 mg Q2W if the week 8 LDL C was 70 mg dL. To maintain blinding, the patient and investigator were not informed of the week 8 LDL C levels, continuation or up titration of dose occurred in an auto mated and blinded manner. The 150 mg Q2W dose of alirocumab was also administered as a 1 mL solution in an auto injector.

STAT family proteins are localized

STAT family proteins are localized Vandetanib structure primarily in the cytoplasm, but upon activation they dimerize and localize to the nucleus to regulate genes involved with cellular growth, proliferation and metastasis. STAT3 is phosphorylated on a tyrosine residue by Janus kinases. Abnormal JAK activity is primarily responsible for the constitutive activation of STAT3 and the development of a tumorigenic phenotype in various cancers, including colon. Therefore, disrupting the activation of STAT3 has the potential to enhance chemotherapy induced apoptosis and treatment outcomes. Interleukin 6 is an inflammatory chemokine released by a variety of cells, including T cells and macrophages, which binds and signals through the IL 6 receptor and the B receptor subunit glycoprotein 130.

IL 6 stimulation through gp130 activates the JAK STAT pathway, leading to cell prolifera tion and survival. IL 6 has been linked to metasta sis into bone and elevated IL 6 levels have been observed in various tumors and cell lines. Thus, aberrantly high IL 6 levels cause the phosphorylation of STAT3, leading to cancer cell survival. In colon cancer, the membrane bound IL 6 receptor expres sion was found to be decreased, whereas the production of soluble IL 6 receptor was increased, leading to greater STAT activation and the induction of pro survival proteins. IL 6 signaling has been shown to be TGF beta dependent, where suppression of TGF beta led to decreased STAT activation and the prevention of in vivo tumor progression. Currently, patients with node positive or metastatic colon cancer demonstrate an overall survival benefit when treated with a fluoropyrimidine based regimen.

Colon cancer patients with metastatic disease receiving an OXP combination chemotherapy are about twice as likely to respond to treatment compared to the same drug combinations without OXP. It has also been demonstrated that these patients survive longer. Over the last decade, similar fluoropyrimidine combinations have been evaluated in patients with node positive disease, and unlike patients with metastatic colon cancer, improvement in clinical outcome was only demonstrated in regimens of a fluoropyrimidine alone or in combination with OXP, also referred to as FOLFOX. Unfortunately, the survival benefits of patients treated with a combination of 5 fluorouacil leucovorin, and, the CPT analog, irinotecan is restricted to stage IV colon cancer, and the response rate in this patient population is roughly about 50%.

The benefits of FOLFOX post operative systemic therapy has been clearly demonstrated in stage III disease, the value in stage II is small but present, and on subgroup analysis, patients with high risk stage II tumors demonstrated a trend toward improved disease free survival. Current standard, supported by the National Comprehensive Cancer Network is FOLFOX and consists of 5 fluorouracil, leucovorin, and oxaliplatin.
