Project description:p53 suppresses tumor progression and metastasis by regulating a large set of genes and microRNAs. By profiling 92 primary hepatocellular carcinomas (HCCs) and 9 HCC cell lines, we found that p53 upregulates microRNAs including miR-200 and miR-192 family members.
Project description:Hepatocellular carcinoma (HCC) remains a significant clinical challenge due to limited diagnostic and therapeutic options. Non-coding RNAs, such as microRNAs (miRNAs), play key roles in cancer biology. Our previous findings showed that miR-423-5p exerts anti-cancer effects on HCC patients treated with sorafenib by promoting autophagy. In this study, we investigated the molecular mechanisms underlying its activity by generating SNU-387 HCC cell line stably overexpressing miR-423-5p and conducting a comprehensive proteomic analysis. Mass spectrometry profiling identified 698 differentially expressed proteins (DEPs) in miR-423-5p-overexpressing cells compared to controls. Functional enrichment analysis revealed significant alterations in metabolic pathways, particularly purine/pyrimidine metabolism and gluconeogenesis. To relate these findings to clinical context, we integrated experimentally validated and predicted miR-423-5p targets with The Cancer Genome Atlas (TCGA) Liver Hepatocellular Carcinoma (LIHC) dataset. Seven candidate proteins were significantly associated with patient prognosis (log-rank p < 0.05 for both overall and disease-free survival). These targets were downregulated in our miR-423-5p model but found to be upregulated in stage III HCC tissues from TCGA data.

Project description:mRNA expression profile modified by stable transfection of microRNA mir-517a (MIR517A) in a human hepatocellular carcinoma cell line Huh-7 Keywords: Hepatocellular carcinoma, Expression array, microRNA
Project description:mRNA expression profile modified by stable transfection of microRNA mir-517a (MIR517A) in a human hepatocellular carcinoma cell line Huh-7 Keywords: Hepatocellular carcinoma, Expression array, microRNA microRNA mir-517a (MIR517A) was transfected to Huh-7 cells using GFP-expressing lentiviral vector. Infected cells were selected using flow cytometry and subjected to mRNA expression microarray experiment. The profiles were compared to controls cells infected with only GFP protein.
Project description:We report the application of miRNAs analysis in exosomes based on second-generation high-throughput sequencing. Plasma samples from 3 hepatocellular carcinoma patients and 3 healthy controls were collected, and exosomes were isolated by ultra-centrifugation. MiRNAs in exosomes were then extracted and high-throughput sequencing was performed.By comparing the sequencing data, we screened out differentially expressed miRNAs and validated them with qRT-PCR in exosome samples, establishing and verifying the diagnostic panel of hepatocellular carcinoma composed of miR-212-5p, miR-519b-3p, miR-1248 and miR-1250-5p.
Project description:miR-19b was up-regulated with hepatocellular carcinoma. We compared the transcriptional profile of Hep 3B transfected with miR-19b inhibitor with Hep3B transfected with control to identify genes affected by miR-19b knockdown.
