(Submitter supplied) Hepatocellular carcinoma (HCC) is a cancer with global impact and largely refractory to current treatments. Novel treatment options are therefore urgently needed. MicroRNAs play important regulatory roles in HCCs and are emerging as promising therapeutic options against HCC. We identified tumor suppressor miRNAs that may attenuate tumor development and contribute to HCC regression. We identified miR-342-3p as a promising tumor suppressor miRNA. more...

(Submitter supplied) Progressing and regressing liver tumor tissues (depending on the group) were subjected to miRNA profiling to identify the miRNA changes occuring during tumor development and regression. Conditional doxycyline-regulatable c-Myc-driven mice get liver tumors following doxycycline (Dox) withdrawal from their diet. When mice are re-administered Dox through their diet, tumors start to regress.

(Submitter supplied) Triple negative breast cancer (TNBC) represents a challenging tumor type due to their poor prognosis and limited treatment options. It is well recognize that clinical and molecular heterogeneity of TNBC is driven in part by mRNA and lncRNAs. To stratify TNBCs, we profiled mRNAs and lncRNA in 158 adjuvant TNBC tumors using an Affymetrix microarray platform. Lehmann clustering analysis allowed us to identify TNBC subtypes featuring unique lncRNA expression patterns, disease free and overall survival rates and particular gene ontology enrichments (performed with GSEA algorithm).

(Submitter supplied) Primary hepatic tumors mainly include hepatocellular carcinoma (HCC), which is one of the most frequent causes of cancer-related deaths worldwide. Thus far, HCC prognosis has remained extremely poor given the lack of effective treatments. Numerous studies have described the roles played by microRNAs (miRNAs) in cancer progression and the potential of these small noncoding RNAs for diagnostic or therapeutic applications. more...

(Submitter supplied) Numerous studies have described the critical role played by microRNAs (miRNAs) in cancer progression and the potential of these small non-coding RNAs for diagnostic or therapeutic applications. However, the mechanisms responsible for the altered expression of miRNAs in malignant cells remain poorly understood. Herein, via epigenetic unmasking, we identified a group of miRNAs located in the imprinted delta like non-canonical Notch ligand 1 (DLK1)-maternally expressed 3 (MEG3) locus that were repressed in hepatic tumor cells. more...

(Submitter supplied) Purpose: To investiagte why maternal obesity induces the susceptibility of offspring to diethylnitrosamine (DEN)-induced hepatocellular carcinoma (HCC) over generations upon over nutrition.The goals of this study are to find over-generationally altered genes and miRNAs which may contribute the accumulative progeny susceptibility to HCC under over nutrition. Methods: C57BL/6 female mice (F0 generation) were fed with either normal chow (NC) or HFD (60% kcal fat) from 1-month to 3-month old, and mated with NC-fed male mice to produce F1 generation. more...

(Submitter supplied) Purpose: miR-181 is upregulated in human liver cancer. The cancer genome atlas (TCGA) liver cancer data show that the iCluster1 subclass of hepatocellular carcinoma (HCC) has a higher expression of miR-181 than either the iCluster2 or iCluster3 subclass, suggesting it may be a driver of oncogenesis. However, the miR-181 family has also been reported to inhibit tumour progression. Thus, we aim to examine the function of miR-181 and its vital mediators in hepatocarcinogenesis. more...

(Submitter supplied) Hepatitis B virus (HBV) infection is one of the major causes of hepatocellular carcinoma (HCC). Nucleos(t)ide analogue (NA) therapy is effective to reduce the HCC incidence, while it doesn’t completely prevent HCC. In this study, we explored the involvement of microRNA (miRNA) in the post-NA treatment HCC development. Chronic hepatitis B (CHB) patients who received NA treatment (n = 18) were divided into 2 groups: those who didn’t develop HCC during the follow-up period (non-HCC group) and those who developed HCC after treatment (HCC group). more...

(Submitter supplied) To clarify the role of miR-199a-3p in HCC, we carried out a gene expression microarray analysis using HCC cell lines (HLE and HLF) transfected with a miR-199a-3p mimic or a negative control. We found that 819 genes were downregulated (>2-fold) by miR-199a-3p in both cell lines.

(Submitter supplied) MicroRNA-122, an abundant and conserved liver-specific miRNA, regulates hepatic metabolism and functions as a tumor suppressor, yet systematic and direct biochemical elucidation of the miR-122 target network remains incomplete. To this end, we performed Argonaute crosslinking immunoprecipitation (Ago-CLIP) sequencing in miR-122 knockout and control mouse livers, as well as in matched human hepatocellular carcinoma (HCC) and benign liver tissue to identify miRNA target sites transcriptome-wide in two species. more...
