Project description:To identify the novel tumor suppressors in hepatocellular carcinoma (HCC), we have employed whole genome microarray expression profiling as a discovery platform in HCC and paired normal liver tissues to identify genes which down-regulated in HCC. Among which, INTS6 and its pseudogene, namely INTS6P1, were found to be dramatically down-regulated in HCC. The down-regulated expression of INTS6 and INTS6P1 in HCC was further confirmed by real-time PCR. RNA was extracted from 3 pairs of HCC and normal liver tissue harvested from patients to undergo microarray study.

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:From a previous microarray study we developed a small chondrogenesis model. We performed qPCR and measured how knockdown of miR-199a-5p or miR-199b-5p could modulate chondrogenesis. Several experiments were used to determine the parameters of this model. We utilised parameter scan and manual sliding to refine the model. Within are two models - an initial model which only comprises of genes which we have data for, and an enhanced model which expands of the initial model to make more predictions - e.g. how miR-140-5p is indirectly regulated by miR-199a-5p and miR-199b-5p.

Project description:Meis1 is a transcription factor involved in a broad range of functions including development and proliferation and has been previously shown to harness cell cycle progression. This study aimed to investigate the regulation of Meis1 by long non-coding RNAs (lncRNAs) and their sponged microRNAs (miRNAs) and hence the impact of this regulatory axis on cell proliferation. Using in-silico analysis, miR-499-5p was predicted to target Meis1 and Malat1 was predicted and previously proven to sponge miR-499-5p. We showed that forcing the expression of miR-499-5p downregulates Meis1 expression in C166 cell line by directly binding to its 3’UTR. In addition, Malat1 knockdown significantly increases miR-499-5p expression, subsequently suppressing Meis1 mRNA and protein expression levels. Furthermore, the impact of manipulating the Malat1/miR-499-5p/Meis1 axis on cellular proliferation was assessed using the BrdU incorporation assay. We demonstrated that upon knockdown of Malat1, mimicking with miR-499-5p, or knockdown of Meis1, cell proliferation was induced. Gene Ontology, KEGG and Reactome enrichment analyses were performed on proteins detected by mass spectrometry following manipulation of the Malat1/miR-499-5p/Meis1 axis. The data revealed a multitude of differentially expressed proteins (DEPs) significantly enriched in processes related to cell cycle, cell division and proliferation. These DEPs were also involved in key signaling pathways, such as Wnt and mTOR, known to play critical roles in cell proliferation and cell cycle. Finally, since Malat1 and miR-499-5p are conserved in humans and mice, we examined the expression pattern of both non-coding RNAs (ncRNAs) in the hearts of neonatal, postnatal, and adult mice, representing models of proliferative and non-proliferative tissues. We demonstrated a paradoxical expression pattern, where Malat1 is underexpressed while miR-499-5p is overexpressed in proliferative neonatal cardiomyocytes. Collectively, our findings confirm that Malat1 sponges miR-499-5p which directly regulates Meis1, and that Malat1/miR-499-5p/Meis1 axis has a pivotal influence on cellular proliferation.

Project description:In order to identify the targets of miR-193a-5p in osteosarcoma U2OS cell line, we used a lentivirus-mediated expression system to overexpressing miR-193a precusor, miR-193a-5p target sequence and non-target sequence, respectively, in osteosarcoma cell line U2OS. A tandem mass tag (TMT)-based quantitative proteomic strategy was employed to identify the global profile of miR-193a-5p-regulated proteins. order to identify the targets of miR-193a-5p, we used a lentivirus-mediated expression system to overexpressing miR-193a precusor, miR-193a-5p target sequence and non-target sequence, respectively, in osteosarcoma cell line U2OS.
