Identification of miR-194-5p target genes in gastric cancer

ABSTRACT: Increasing studies report that miR-194-5p plays a tumor suppressor role in gastric cancer (GC). Previous studies have revealed that miR-194 inhibited gastric cancer progression through different pathways by affecting the expression level of different target genes. For example, miR-194 have been reported to be able to regulate the expression of FOXM1, NR2F2, BMI1, SDAD1, RBX1, KDM5B, ZEB1 and AKT2 etc. It suggested that miR-194 may play complicated roles in GC. To figure out the mechanism of miR-194' tumor suppressor role in GC, we performed RNA sequencing in two different GC cell lines. Our studies showed that miR-194 tends to regulated target genes by binding on their 3' untranslated regions with either 7-mer-A1 or 7-mer-m8 or 8-mer. Approximately 138 genes were downregulated in both SGC7901 and BGC823 cell lines that transfected with miR-194-5p mimics compared to negative control siRNAs. Most of the downregulated genes have not reported yet.

Serum miRNA profiles for gastric cancer diagnosis

Project description:Circulating microRNAs (miRNAs) in serum may serve as promising diagnostic biomarkers for patients with gastric cancer (GC). Using quantitative reverse transcription polymerase chain reaction (qRT-PCR) based Exiqon panel, we identified 58 differentially expressed miRNAs from 3 GC pool samples and 1 normal control (NC) pool in the initial screening phase. Identified miRNAs were further validated in the training (49 GC VS. 47 NCs) and validation phases (154 GC VS. 120 NCs) using qRT-PCR. Consequently, six serum miRNAs (miR-10b-5p, miR-132-3p, miR-185-5p, miR-195-5p, miR-20a-3p and miR-296-5p) were significantly overexpressed in GC compared with NCs. The areas under the receiver operating characteristic (ROC) curve of the six-miRNA panel were 0.764 and 0.702 for the training and validation phases, respectively. In conclusion, we identified a six-miRNA panel in serum for the detection of GC.

Lysine tRNA fragments and miR-194-5p co-regulate hepatic steatosis via β-Klotho and Perilipin 2 (RNA)

Project description:Non-alcoholic fatty liver disease (NAFLD) involves hepatic accumulation of intracellular lipid droplets via incompletely understood processes. Here, we report distinct and cooperative NAFLD roles of LysTTT-5’tRF transfer RNA fragments and microRNA miR-194-5p. Unlike lean animals, dietary-induced NAFLD mice showed concurrent hepatic decrease of both LysTTT-5’tRF and miR-194-5p levels, which were restored following miR-132 antisense oligonucleotide treatment which suppresses hepatic steatosis. Moreover, exposing human-derived Hep G2 cells to oleic acid for 7 days co-suppressed miR-194-5p and LysTTT-5’tRF levels while increasing lipid accumulation. Importantly, transfecting fattened cells with a synthetic LysTTT-5’tRF mimic elevated mRNA levels of the metabolic regulator β-Klotho while decreasing triglyceride amounts by 30% within 24 hours. In contradistinction, antisense suppression of miR-194-5p induced accumulation of its novel target, the NAFLD-implicated lipid droplet-coating PLIN2 protein. Further, two out of 15 steatosis-alleviating screened drug-repurposing compounds, Danazol and Latanoprost, elevated miR-194-5p or LysTTT-5’tRF levels. The different yet complementary roles of miR-194-5p and LysTTT-5’tRF offer new insights into the complex roles of small non-coding RNAs and the multiple pathways involved in NAFLD pathogenesis.
