3'-UTR Polymorphisms in Thymidylate Synthase with Colorectal Cancer Prevalence and Prognosis. J Pers Med 2021; 11:jpm11060537. [PMID: 34207922 PMCID: PMC8228787 DOI: 10.3390/jpm11060537] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2021] [Revised: 05/23/2021] [Accepted: 06/04/2021] [Indexed: 11/17/2022] Open
Abstract
Colorectal cancer (CRC) is the third most common type of cancer and the second leading cause of cancer-related mortality in Western countries. Polymorphisms in one-carbon metabolism and angiogenesis-related genes have been shown to play important roles in tumor development, progression, and metastasis for many cancers, including CRC. Moreover, recent studies have reported that polymorphisms in specific microRNA (miRNA)-binding regions, which are located in the 3'-untranslated region (UTR) of miRNA-regulated genes, are present in a variety of cancers. Here, we investigated the association between two thymidylate synthase (TYMS or TS) 3'-UTR polymorphisms, 1100T>C [rs699517] and 1170A>G [rs2790], and CRC susceptibility and progression in Korean patients. A total of 450 CRC patients and 400 healthy controls were enrolled in this study, and genotyping at the TS locus was performed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) or TaqMan allelic discrimination assays. We found that TS 1170A>G genotypes, as well as the TS 1100T-1170G and 1100C-1170A haplotypes, are strongly associated with CRC. The TS 1100TC+CC type was associated with a poor survival (OS and RFS) rate. In addition, levels of the TS 1100C and TS 1170G allele were found to be significantly increased in CRC tissue. Our study provides the first evidence for 3'-UTR variants in TS genes as potential biomarkers of CRC prognosis and prevention.

Abstract
The incidence rates of type 2 diabetes mellitus (T2DM) and colorectal polyps have been increasing over the last decades. However, direct associations between T2DM and colorectal polyps have not been extensively reported. We will explore the relationship between T2DM and colorectal polyps.In the retrospective study, we classified DM and NonDM groups (control) from 993,516 people in Taiwan nationwide population insurance database from the period of 2000 to 2013. We collected data on income and comorbidities through the international classification of diseases, ninth revision-clinical modification (ICD-9-CM) codes.The T2DM group had a higher incidence rate of colorectal polyps (31.97%, 95% confidence interval [CI] = 30.97-33.28) than the control group (25.9%, 95% CI = 25.1-26.72), and the crude incidence ratio was 1.235 (95% CI = 1.174-1.300). In 13 years of follow-up (2000-2013), T2DM was linked to a significantly higher cumulative probability of colorectal polyps (log-rank test: P = .0001).Patients with T2DM had a 1.23-fold higher risk of new colorectal polyps than control patients in 13 years of follow-up. We explain the T2DM increases incidence for colorectal polyps in long term follow-up.

Colonic Lysine Homocysteinylation Induced by High-Fat Diet Suppresses DNA Damage Repair. Cell Rep 2019; 25:398-412.e6. [PMID: 30304680 DOI: 10.1016/j.celrep.2018.09.022] [Citation(s) in RCA: 58] [Impact Index Per Article: 11.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2018] [Revised: 08/15/2018] [Accepted: 09/07/2018] [Indexed: 02/05/2023] Open
Abstract
Colorectal cancer (CRC) onset is profoundly affected by Western diet. Here, we report that high-fat (HF) diet-induced, organ-specific colonic lysine homocysteinylation (K-Hcy) increase might promote CRC onset by impeding DNA damage repair. HF chow induced elevated methionyl-tRNA synthetase (MARS) expression and K-Hcy levels and DNA damage accumulation in the mouse and rat colon, resulting in a phenotype identical to that of CRC tissues. Moreover, the increased copy number of MARS, whose protein product promotes K-Hcy, correlated with increased CRC risk in humans. Mechanistically, MARS preferentially bound to and modified ataxia-telangiectasia and Rad3-related protein (ATR), inhibited ATR and its downstream effectors checkpoint kinase-1 and p53, and relieved cell-cycle arrest and decreased DNA damage-induced apoptosis by disrupting the binding of ATR-interacting protein to ATR. Inhibiting K-Hcy by targeting MARS reversed these effects and suppressed oncogenic CRC cell growth. Our study reveals a mechanism of Western-diet-associated CRC and highlights an intervention approach for reversing diet-induced oncogenic effects.

Colorectal polyp risk is linked to an elevated level of homocysteine. Biosci Rep 2018; 38:BSR20171699. [PMID: 29581245 PMCID: PMC5968185 DOI: 10.1042/bsr20171699] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2017] [Revised: 03/19/2018] [Accepted: 03/26/2018] [Indexed: 02/06/2023] Open
Abstract
Several studies have reported an association between levels of folate, homocysteine, and vitamin B12 and the risk of colorectal polyps. Here, our aim is to examine the possible effect of folate, homocysteine, and vitamin B12 levels on the risk of colorectal polyps by means of meta-analysis based quantitative synthesis. According to our inclusion/exclusion criteria, a total of 13 case–control studies were enrolled. The P-value of the association test, standard mean difference (SMD), and 95% confidence interval (CI) were calculated. Pooled analysis data showed a negative correlation between the risk of colorectal polyps and the levels of serum folate, red blood cell (RBC) folate, or vitamin B12 (all P>0.05). Nevertheless, for homocysteine level, we also observed a statistically significant difference between cases and controls in the overall and subgroup analysis of hospital-based control (HB), population-based control (PB), Chinese, Caucasian, or Asian (all P<0.05, SMD > 0). We found that increased levels of homocysteine may be statistically and significantly related to the risk of colorectal polyps.

Abstract
Polymorphisms in the methylenetetrahydrofolate reductase (MTHFR) play important roles in tumor development, progression, and metastasis. Moreover, recent studies have reported that a number of 3′-UTR polymorphisms potentially bind to specific microRNAs in a variety of cancers. The aim of this study was to investigate the association of four MTHFR polymorphisms, 2572C>A [rs4846049], 4869C>G [rs1537514], 5488C>T [rs3737967], and 6685T>C [rs4846048] with colorectal cancer (CRC) in Koreans. A total of 850 participants (450 CRC patients and 400 controls) were enrolled in the study. The genotyping of MTHFR 3′-UTR polymorphisms was performed by polymerase chain reaction-restriction fragment length polymorphism analysis or TaqMan allelic discrimination assay. We found that MTHFR 2572C>A, 4869C>G, and 5488C>T genotypes were substantially associated with CRC susceptibility. Of the potentially susceptible polymorphisms, MTHFR 2572C>A was associated with increased homocysteine and decreased folate levels in the plasma based on MTHFR 677CC. Our study provides the evidences for 3′-UTR variants in MTHFR gene as potential biomarkers for use in CRC prevention.

ANNALS OF NUTRITION AND METABOLISM 2014; 64:106-12.

Abstract
BACKGROUND/AIMS The links between the metabolic syndrome and homocysteine in relation to the risk of colorectal polyps are not understood. The purpose of this study was to investigate the association between the metabolic syndrome and homocysteine and further analyze the relationship between these two factors and the risk of colorectal polyps. METHODS This was a case-control study. A total of 135 participants with colorectal polyps (cases) and 110 participants without polyps (controls) were recruited. RESULTS There were 59 participants with the metabolic syndrome in the case group and 36 participants with the metabolic syndrome in the control group. The metabolic syndrome and its individual components, except for serum triglycerides, and homocysteine were associated with the risk of colorectal polyps. When the association of the metabolic syndrome and homocysteine with the risk of colorectal polyps was simultaneously considered, the association between homocysteine and the risk of colorectal polyps disappeared, but waist circumference, systolic and diastolic blood pressure, high-density lipoprotein cholesterol, and the metabolic syndrome itself were still significant risk factors for the development of colorectal polyps. CONCLUSION Although the metabolic syndrome and plasma homocysteine were individually related to the risk of colorectal polyps, the metabolic syndrome was a major contributing factor in relation to the risk of colorectal polyps independent of plasma homocysteine.
