(Submitter supplied) The aim of this study was to identify at genome-wide level, the effect of miR-122 on the distribution of its responsive genes on the polyribosomes. For this purpose human hepatoma cells Huh-7 were transfected for 48 hrs with LNA-based miR-122 inhibitors (122-PM) or miR-122 mimics (122-MIM). Following the treatment with cycloheximide, cells were lysed and layered on a 10-50% sucrose gradient. Following ultracetrifigation the polyribosomes were separated in 12 different fractions

(Submitter supplied) Small, non-coding RNAs control gene expression post-transcriptionally and play important roles in virus-host interactions. Within the liver, the microRNA (miRNA) miR-122 is essential for replication of hepatitis C virus (HCV), while repression of miR-148a by hepatitis B virus (HBV) may enhance tumorigenesis. Despite their importance to the outcome of these infections, few previous studies have described unbiased profiling of small RNAs in the liver during chronic viral hepatitis. more...

(Submitter supplied) Six frozen hepatocellular carcinoma (HCC) samples (three without cirrhotic and three with cirrhotic background) were selected to analyze the circRNA expression profile through circRNA-seq. A total of 20334 circRNAs were identified in these tumor tissues, which were widely distributed in all chromosomes. Differential analysis revealed that 393 were significantly dysregulated in non-cirrhotic HCC when compared with cirrhotic HCC tissues (log2(fold change) > 1 and p < 0.05). more...

(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) E2F/RB activity is altered in most human tumors. The retinoblastoma family of proteins plays a key role in regulating the progression of the cell cycle from the G1 to S phases. This is achieved through negative regulation of E2F transcription factors, important positive regulators of cell cycle entry. E2F family members are divided in two groups: activators (E2F1-E2F3a) and repressors (E2F3b-E2F8). E2F4 accounts for a large part of the E2F activity and is a main E2F repressor member in vivo. Perturbations in the balance from quiescence towards proliferation contribute to increased mitotic gene expression levels frequently observed in cancer. We have previously reported that combined Rb1-Rbl1 and Rb1-E2F1 ablation in epidermis produces important alterations in epidermal proliferation and differentiation, leading to tumor development. However, the possible roles of E2F4 in this context are still to be determined. Here we show the absence of any discernible phenotype in the skin of mice lacking of E2F4. In contrast, the inducible loss of Rb1 in the epidermis of E2F4-null mice produced multiple skin abnormalities including altered differentiation and proliferation, spontaneous wounds, carcinoma in situ development and stem cell perturbations. All these phenotypic alterations are associated with extensive gene expression changes, the induction of c-myc and the Akt activation. Moreover, the whole transcriptome analyses in comparison with previous models generated also revealed extensive changes in multiple repressive complexes and in transcription factor activity. These results point to E2F4 as a master regulator in multiple steps of epidermal homeostasis in Rb1 absence.

(Submitter supplied) MicroRNAs is a rapidly expanding area expected to change the way in which diseases will be diagnosed, treated and monitored in the future. Hepatocellular carcinoma (HCC) shows a rising incidence with high mortality but lack of effective targeted therapies. We identified the aberrantly expressed miRNAs involved in HCC through the comparison of miRNA expression profiling in cancerous hepatocytes with that in normal primary human hepatocytes and found 37 dysregulated miRNAs in HCC. more...

(Submitter supplied) Hepatocellular carcinoma (HCC) represents the major histological subtype of liver cancer. Tumorigenic changes in hepatic cells potentially result from aberrant expression of microRNAs (miRNAs). Individual microRNA gene may give rise to miRNAs of different length, named isomiRNAs that proved to be functionally relevant. Results: We detected 374 microRNAs expressed in liver, including miR-122-5p that constituted over 39% ofthe hepatic miRnome. more...
