SLAS DISCOVERY : ADVANCING LIFE SCIENCES R & D 2022; 27:258-265. [PMID: 35413475 DOI: 10.1016/j.slasd.2022.04.001] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/23/2021] [Revised: 03/22/2022] [Accepted: 04/05/2022] [Indexed: 06/14/2023]
Abstract
BACKGROUND Kaposi's sarcoma-associated herpes virus (KSHV) initiate and accelerate the development of Kaposi's sarcoma (KS), and KSHV possesses many cancer-associated genes, including KSHV-derived microRNA miR-K12-1, which has been identified to be closely associated with KS progression. However, the detailed mechanisms by which miR-K12-1 facilitates HIV-related gastrointestinal KS development are still not fully delineated. OBJECTIVES This study strived to evaluate the effect of miR-K12-1 on the progression of HIV-related gastrointestinal KS. MATERIALS AND METHODS The expression levels of miR-K12-1 in HIV-related gastrointestinal KS tissues were determined by RT-qPCR. Proliferation and apoptosis were assessed by colony formation, CCK-8 and flow cytometry, respectively. The expression of all proteins was detected by Western blot. The in vivo effect of miR-K12-1 on the formation of a tumor was explored by using the mouse xenograft model. RESULTS In this study, we uncovered that KSHV-miR-K12-1 was upregulated in HIV-related gastrointestinal KS tissues and associated with poor outcome in HIV-related gastrointestinal KS patients. Compared with the control group, after miR-K12-1 inhibitor transfection, BCBL-1 cell viability was decreased, and the cell apoptosis was significantly increased, whereas transfection of miR-K12-1 mimics promoted cell proliferation and mitosis. In addition, our rescuing experiments verified that miR-K12-1 promoted cell proliferation via activating the PI3K/Akt pathway, and inhibition of the PI3K/Akt pathway by LY294002 abrogated the tumor-promoting effects of miR-K12-1 in HIV-related gastrointestinal KS. CONCLUSIONS In summary, we concluded that KSHV-derived miR-K12-1 activate the PI3K/Akt pathway to initiate and accelerate the development of KS, which convinces us that miR-K12-1 can be used as potential biomarkers for KS diagnosis, treatment and prognosis.

Genetic predisposition of SNPs in miRNA-149 (rs2292832) and FOXE1 (rs3758249) in thyroid Cancer. Mol Biol Rep 2021; 48:7801-7809. [PMID: 34643920 DOI: 10.1007/s11033-021-06795-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2021] [Accepted: 09/10/2021] [Indexed: 10/20/2022]
Abstract
BACKGROUND Many efforts have been made in recent years to investigate the alterations in protein-coding genes as well as non-coding RNAs that are playing an emerging role in the development and progression of cancers. These miRNAs are short non-coding functional RNAs that are involved in the regulation of transcriptome. In different studies, it was found that human miRNA-149 is an important microRNA that is functioning either as onco-miRNAs or acting as tumor suppressors, in different conditions. RATIONALE Many of the miRNAs are regulating different SNPs of FOXE1 in different studies which are causing low-to-moderate penetrance of genes that initiates the development of thyroid cancer. The involvement of SNPs in miRNA-149 gene rs2292832 and FOXE1 rs3758249 with PTC for better disease prognosis and management was determined in this study and the relation between these SNPs at the genotypic level was also evaluated. MATERIALS AND METHODS: PTC patients with age and gender-matched controls were recruited in the present study. Blood samples were collected in EDTA vacutainer followed by DNA extraction by the organic method. Genotyping of rs2292832 and rs3758249 was done by ARMS-PCR and PCR- RFLP respectively. Statistical analyses were carried out by using SPSS software (version 20). RESULTS The mutation T>C in miRNA-149 rs2292832 was significantly associated with thyroid cancer (p-value 0.0004, < 0.05) while rs3758249 G>C did not show significant association with the disease (p-value 0.124244, > 0.05). Moreover, no correlation of rs2292832 at the genotype level was observed with rs3758249. CONCLUSIONS miRNA-149 gene SNP rs2292832 was observed in strong association with thyroid cancer. Lack of genetic association of rs3758249 of FOXE1 gene has been ruled for the disease. The statistically significant association of rs2292832 with thyroid cancer depicts its mechanistic involvement at the cellular level in Papillary Thyroid Carcinoma.

Association of mir-196a-2 rs11614913 and mir-149 rs2292832 Polymorphisms With Risk of Cancer: An Updated Meta-Analysis. Front Genet 2019; 10:186. [PMID: 30930933 PMCID: PMC6429108 DOI: 10.3389/fgene.2019.00186] [Citation(s) in RCA: 33] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2018] [Accepted: 02/19/2019] [Indexed: 12/14/2022] Open
Abstract
Background: Accumulating evidence suggests that functional dysregulations of miRNAs, especially miR-196a-2 and miR-149, in cancers could be attributed to polymorphisms in miRNA sequences. This study was aimed at clarifying the association of mir-196a-2 rs11614913 and mir-149 rs2292832 with cancer risk by performing an updated meta-analysis of genetic association studies. Methods: PubMed, Embase, Scopus, and ScienceDirect databases were searched until 9 April 2018 to identify eligible studies. Studies should meet the following criteria to be included in the meta-analysis: evaluation of genetic association between rs11614913 and/or rs2292832 and susceptibility to cancer; A case-control design; Written in English; Availability of sufficient data for estimating odds ratio (OR) and its 95% confidence interval (95%CI). Studies that met the following criteria were excluded: review articles, meta-analysis, abstracts or conference papers; duplicate publications; studies on animals or cell-lines; studies without a case-control design; studies that did not report genotype frequencies. Pooled ORs and 95% CIs were estimated using a total of 111 studies (41,673 cases and 49,570 controls) for mir-196a rs11614913 and 44 studies (15,954 cases and 19,594 controls) for mir-149 rs2292832. Stratified analysis according to quality scores, genotyping method, ethnicity, broad cancer category and cancer type was also performed. Results: Mir-196a-2 rs11614913 T allele was associated with decreased cancer risk in overall population. The association was only significant in Asians but not Caucasians. In subgroup analysis, significant associations were found in high quality studies, gynecological cancers, ovarian, breast, and hepatocellular cancer. Mir-149 rs2292832 was not associated with cancer risk in overall population and there were no differences between Asians and Caucasians. However, the T allele was associated with a decrease risk of gastrointestinal tract cancers under the heterozygote model and an increased risk of colorectal cancer under the recessive model. Conclusions: The present meta-analysis suggests that mir-196a-2 rs11614913 may contribute to the risk of cancer especially in Asians. Mir-149 rs2292832 may modulate the risk of gastrointestinal tract cancers especially colorectal cancer. This study had some limitations such as significant heterogeneity in most contrasts, limited number of studies enrolling Africans or Caucasians ancestry and lack of adjustment for covariates and environmental interactions.

Abstract
microRNAs (miRNAs) are nowadays recognized as an essential component of gene regulatory networks. Furthermore, deregulation of miRNAs expression often contributes to human pathologies. Recently, a substantial number of single nucleotide polymorphism (SNPs) and rare mutations within pri-, pre- and mature miRNA sequences have been reported. These miRNA SNPs have often been associated with human disease. However, due to the complexity of miRNA biogenesis and the genome-wide functional effects of miRNAs, the determination of biological consequences of these miRNA SNPs remains challenging. Despite an increasing number of reports linking miRNA SNPs with human pathologies, few reports have analyzed the mechanism by which miRNA-SNPs contribute to disease pathogenesis. In this review, we discuss how single polynucleotide polymorphisms in miRNAs genes may influence miRNAs expression and function and thus potentially alter disease pathogenesis.
