Abstract
m6A methylation is the most frequent modification of mRNA in eukaryotes and plays a crucial role in cancer progression by regulating biological functions. Insulin-like growth factor 2 mRNA-binding proteins (IGF2BP) are newly identified m6A 'readers'. They belong to a family of RNA-binding proteins, which bind to the m6A sites on different RNA sequences and stabilize them to promote cancer progression. In this review, we summarize the mechanisms by which different upstream factors regulate IGF2BP in cancer. The current literature analyzed here reveals that the IGF2BP family proteins promote cancer cell proliferation, survival, and chemoresistance, inhibit apoptosis, and are also associated with cancer glycolysis, angiogenesis, and the immune response in the tumor microenvironment. Therefore, with the discovery of their role as 'readers' of m6A and the characteristic re-expression of IGF2BPs in cancers, it is important to elucidate their mechanism of action in the immunosuppressive tumor microenvironment. We also describe in detail the regulatory and interaction network of the IGF2BP family in downstream target RNAs and discuss their potential clinical applications as diagnostic and prognostic markers, as well as recent advances in IGF2BP biology and associated therapeutic value.

Abstract
Colorectal cancer is the third most common malignant tumor worldwide, causing serious harm to human health. Epigenetic modification, especially RNA methylation modification, plays a critical role in the occurrence and development of colorectal cancer via post-transcriptional regulation of mRNA and non-coding RNA expression. Among these, N6-methyladenosine (m6A) is the most common chemical modification in mammals, which plays an important role in the progress of cancer, including colorectal cancer. m6A is a dynamic and reversible process and is mainly regulated by m6A methyltransferase ("writers"), m6A demethylases ("erasers"), and m6A binding proteins ("readers"). Herein, we reviewed recent advances in the role of m6A modification in colorectal cancer and focused on the factors affecting m6A modification. Furthermore, we discussed the clinical application of m6A modifications for colorectal cancer diagnosis, prognosis, and treatment and provided guides in clinical practice. m6A modification and m6A regulators play significant roles in the occurrence and development of colorectal cancer by regulating the stability and translation of mRNAs, the maturation of miRNAs, and the function of lncRNAs. m6A regulators can play biological roles in colorectal cancer through m6A-dependent manner or m6A-independent manner. Multiplies of internal factors, including miRNAs and lncRNAs, and external factors can also regulate the m6A modification by completing with m6A regulators in a base complement manner, regulating the expression of m6A and mutating the m6A site. m6A regulators and m6A modificantion are diagnostic and prognostic markers for CRC. Therefore, m6A regulators and m6A modificantion may be potential therapeutic target for CRC in the future.

BMC Genomics 2022; 23:360. [PMID: 35546387 PMCID: PMC9092671 DOI: 10.1186/s12864-022-08576-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2022] [Accepted: 04/21/2022] [Indexed: 12/19/2022] Open
Abstract
BACKGROUND Genome-wide association studies (GWAS) have uncovered thousands of genetic variants that are associated with complex human traits and diseases. miRNAs are single-stranded non-coding RNAs. In particular, genetic variants located in the 3'UTR region of mRNAs may play an important role in gene regulation through their interaction with miRNAs. Existing studies have not been thoroughly conducted to elucidate 3'UTR variants discovered through GWAS. The goal of this study is to analyze patterns of GWAS functional variants located in 3'UTRs about their relevance in the network between hosting genes and targeting miRNAs, and elucidate the association between the genes harboring these variants and genetic traits. METHODS We employed MIGWAS, ANNOVAR, MEME, and DAVID software packages to annotate the variants obtained from GWAS for 31 traits and elucidate the association between their harboring genes and their related traits. We identified variants that occurred in the motif regions that may be functionally important in affecting miRNA binding. We also conducted pathway analysis and functional annotation on miRNA targeted genes harboring 3'UTR variants for a trait with the highest percentage of 3'UTR variants occurring. RESULTS The Child Obesity trait has the highest percentage of 3'UTR variants (75%). Of the 16 genes related to the Child Obesity trait, 5 genes (ETV7, GMEB1, NFIX, ZNF566, ZBTB40) had a significant association with the term DNA-Binding (p < 0.05). EQTL analysis revealed 2 relevant tissues and 10 targeted genes associated with the Child Obesity trait. In addition, Red Blood Cells (RBC), Hemoglobin (HB), and Package Cell Volume (PCV) have overlapping variants. In particular, the PIM1 variant occurred inside the HB Motif region 37,174,641-37,174,660, and LUC7L3 variant occurred inside RBC Motif region 50,753,918-50,753,937. CONCLUSION Variants located in 3'UTR can alter the binding affinity of miRNA and impact gene regulation, thus warranting further annotation and analysis. We have developed a bioinformatics bash pipeline to automatically annotate variants, determine the number of variants in different categories for each given trait, and check common variants across different traits. This is a valuable tool to annotate a large number of GWAS result files.

Abstract
Dysregulated mRNA–miRNA profiles might have the prospective to be used for early diagnosis of gastrointestinal cancers, estimating survival, and predicting response to treatment. Here, a novel biomarker based on miRNAs binding to mRNAs in single nucleotide polymorphism (SNP) sites related to gastrointestinal cancers is introduced that could act as an early diagnosis. The electronic databases used for the recruiting published articles included EMBASE, SCOPUS, Web of Science, and PubMed, based on MESH keywords and PRISMA methodology. Based on the considered criteria, different experimental articles were reviewed, during which 15 studies with the desired criteria were collected. Accordingly, novel biomarkers in prediction, early prognosis, and diagnosis of gastrointestinal cancers were highlighted. Moreover, it was found that 20 SNP sites and 16 miRNAs were involved in gastrointestinal cancers, with altered expression patterns associated with clinicopathological and demographic data. The results of this systematic study revealed that SNPs could affect the binding of miRNAs in the SNP sites that might play a principal role in the progression, invasion, and susceptibility of gastrointestinal cancers. In addition, it was found that the profiles of SNPs and miRNAs could serve as a convenient approach for the prognosis and diagnosis of gastric and colorectal cancers.

Genetic variants of cell cycle pathway genes are associated with head and neck squamous cell carcinoma in the Chinese population. Carcinogenesis 2021; 42:1337-1346. [PMID: 34643214 DOI: 10.1093/carcin/bgab094] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2021] [Revised: 10/01/2021] [Accepted: 10/11/2021] [Indexed: 12/24/2022] Open
Abstract
Genetic alterations in the cell cycle pathway are common in head and neck squamous cell carcinoma (HNSCC). We identified four novel HNSCC susceptibility loci (CDKN1C rs452338, CDK4 rs2072052, E2F2 rs3820028 and E2F2 rs2075993) through a two-stage matched case-control study. There was a combined effect among the four single nucleotide polymorphisms (SNPs), as the number of risk genotypes increased, the risk of HNSCC displayed an increasing trend (Ptrend < 0.001). And there were multiplicative interactions between rs452338 and rs2072052, rs2072052 and rs3820028, rs2072052 and rs2075993. Functional bioinformatics analysis and dual-luciferase reporter assay revealed that E2F2 rs2075993 T>C reduced the stability of E2F2 3'-UTR secondary structure and affected the binding of E2F2 to miR-940, which was up-regulated in HNSCC tumor tissues (P = 2.9e-8) and was correlated with poor overall survival of HNSCC (HR = 1.39, 95% CI = 1.02-1.90). In vitro assays, we discovered that the expression of miR-940 was regulated by METTL3, and miR-940 promoted the proliferation, migration and invasion, and inhibited the senescence and autophagy of tumor cells. In terms of mechanism, compared with rs2075993 allele T, we found that the protective variant rs2075993 allele C interfered with the translational inhibition of E2F2 by miR-940, resulting in increased expression of E2F2 protein, which further reduced the proliferation, migration, invasion, and increased the senescence of tumor cells.

Abstract
Circular RNAs (circRNAs) are an intriguing class of regulatory RNAs involved in the tumorigenesis of many cancers, including colorectal cancer. Mechanistically, circRNAs sponge microRNAs (miRNAs) with specific miRNA response elements (MREs) and compete for regulatory target genes downstream. However, the genetic effects of MREs on colorectal cancer susceptibility remain unclear. The MREs of colorectal cancer-associated circRNAs (CRC-circRNAs) and corresponding single nucleotide polymorphisms (SNPs) were identified by the transcriptome of cancer cells and the 1000 Genomes Project. The association between candidate SNPs and colorectal cancer risk was evaluated in a Chinese population (1150 cases and 1342 controls) and two European populations (9023 cases and 386,896 controls) using logistic regression analysis. Among the 197 candidate SNPs within MREs of 186 CRC-circRNAs, rs25497 in circTUBB was significantly associated with colorectal cancer risk in a Chinese population after false discovery rate (FDR) correction [odds ratio (OR) = 1.78, 95% confidence interval (CI) = 1.44-2.21, P = 1.42 × 10-7, PFDR = 2.80 × 10-5] and even reached significance in a genome-wide association study (GWAS) under the dominant model (P = 1.28 × 10-8). Similar results were found in the European populations (ORmeta = 1.30, 95% CI = 1.10-1.53). Both stratification and interaction analyses revealed that rs25497 interacting with smoking affected the colorectal cancer risk (Pinteraction = 1.48 × 10-2). Here, we first comprehensively identified genetic variants in MREs of CRC-circRNAs and evaluated their effects on colorectal cancer risk in both Chinese and European populations. These findings provide basis for a comprehensive understanding of colorectal cancer etiology.

Abstract
The aim of the present study was to explore the correlations between single nucleotide polymorphisms in LASS2 gene 3'-untranslated regions and bladder cancer risk in Chinese population. We first performed PCR and sequence for LASS2-3'-UTR in 105 bladder cancer patients and 100 control subjects. Next, multivariate logistic regression analysis was used to determine the relationship between single nucleotide polymorphisms frequency and susceptibility of bladder cancer, and clinical features in 105 cases. In addition, survival curves and Cox Regression analysis were used to investigate the effect of single nucleotide polymorphisms on clinical outcome in 58 cases. Finally, quantitative reverse-transcription PCR and immunohistochemical were performed to explore the influence of single nucleotide polymorphisms on LASS2 expression. We found that a single nucleotide polymorphism (rs8444 C>T) located in the 3'-UTR of LASS2 was significantly associated with the risk of bladder cancer. We also showed the frequency of rs8444 T genotype was higher in bladder cancer group and correlated with the risk of clinical prognosis. Yet, there were no significant correlations between T/C allele frequencies and the distributions of rs8444 genotype and tumor-node-metastasis stage, histological grade and distant metastasis in bladder cancer. Furthermore, we demonstrated that rs8444 C>T could affect LASS2 expression by single nucleotide polymorphism-related mRNA stability. Our results showed that LASS2-3'-UTR rs8444 C>T polymorphism was significantly associated with the individual risk and the poor overall survival of bladder cancer, suggesting that rs8444 TT genotype maybe act as an independent risk factor of susceptibility and clinical prognosis for bladder cancer in Chinese population.

J Cell Mol Med 2018; 23:2012-2019. [PMID: 30569605 PMCID: PMC6378227 DOI: 10.1111/jcmm.14104] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2018] [Revised: 11/27/2018] [Accepted: 11/30/2018] [Indexed: 12/20/2022] Open
Abstract
Single nucleotide polymorphisms (SNPs) within binding sites of microRNAs (miRNAs) could modify cancer susceptibility by changing the binding affinity of miRNAs on their target mRNA 3'-untranslated regions (UTRs). MicroRNA-21 (miR-21) is involved in the development of colorectal cancer. However, the relationship between SNPs within the binding sites of miR-21 and colorectal cancer risk has not been widely investigated. A case-control study including 1147 patients and 1203 controls was performed to evaluate the association of SNPs in miR-21 binding sites and colorectal cancer risk. Dual-luciferase reporter assays and functional assays were performed to evaluate the effects of miR-21. The SNP rs6504593 C allele conferred an increased risk of colorectal cancer compared with the T allele in an additive model (odds ratio [OR] = 1.19, 95% confidence interval [CI] = 1.04-1.36, P = 0.011). Dual-luciferase reporter assays demonstrated that the rs6504593 T allele negatively post-transcriptionally regulated IGF2BP1 by altering the binding affinity of miR-21. Additionally, colorectal cancer cells transiently transfected with miR-21 mimics promoted cell proliferation and suppressed apoptosis, whereas inhibition of miR-21 decreased cell growth. These data suggest that the miR-21 binding site SNP rs6504593 in the IGF2BP1 3'-UTR may alter IGF2BP1 expression and contribute to colorectal cancer risk.
