Description
To explore functionally crucial tumor-suppressive (TS)-miRNAs in hepatocellular carcinoma (HCC), we performed integrative function- and expression-based screenings of TS-miRNAs in six HCC cell lines. The screenings identified seven miRNAs, which showed growth-suppressive activities through the overexpression of each miRNA and were endogenously downregulated in HCC cell lines. Further expression analyses using a large panel of HCC cell lines and primary tumors demonstrated four miRNAs, miR-101, -195, -378 and -497, as candidate TS-miRNAs frequently silenced in HCCs. Among them, two clustered miRNAs miR-195 and miR-497 showed significant growth-suppressive activity with induction of G1 arrest. Comprehensive exploration of their targets using Argonute2-immunoprecipitation-deep-sequencing (Ago2-IP-seq) and genome-wide expression profiling after their overexpression, successfully identified a set of cell-cycle regulators, including CCNE1, CDC25A, CCND3, CDK4, and BTRC. Our results suggest the molecular pathway regulating cell cycle progression to be integrally altered by downregulation of miR-195 and miR-497 expression, leading to aberrant cell proliferation in hepatocarcinogenesis. Identification of miR-195 and miR-497 target genes by sequencing Ago2-binding mRNAs and total mRNAs of miR-195 or miR-497 overexpressed, or non-treated Hep G2 cell. Overall design: Deep sequencing of RNAs in Ago2-IP fraction and mRNAs extracted from miR-195 or miR-497 overexpressed, or non-treated Hep G2 cell.

Description
By comprehensive screening of long non-coding RNAs (lncRNAs) over mouse heart development, we have identified Tbx5 upstream antisense RNA (Tbx5ua). In order to understand its function, we produced Tbx5ua knock down ES cells by inserting triple bovine polyadenylation signal to the second exon of Tbx5ua. From the ES cells we made chimeric mouse embryos via tetraploid complementation assay. We conducted RNA-seq analysis on the WT and KD heart ventricles at E9.5 to further elucidate the lncRNA's molecular functions. Overall design: Single-end RNA-seq of total RNAs extracted from the ventricles of tetraploid chimeric mice generated from wildtype or Tbx5ua knockdown B6J ES cells

Description
Fibroadenomas are the most common benign breast tumors in women under 30. Unlike their malignant counterparts, relatively molecular profiling has been done on fibroadenomas. Here we performed gene expression profiling on ten fibroadenomas in order to better characterize these tumors. Through targeted amplicon sequencing, we have found that six of these tumors have MED12 mutations. We show that the MED12 mutations, among others, are associated with activated estrogen signaling, as well as increased invasiveness through upregulation of ECM remodelling genes.

Description
Alas2 gene encodes the rate-limiting enzyme in heme biosynthesis. CRISPR/Cas9-mediated ablation of two Alas2 intronic cis-elements strongly reduced GATA-1-induced Alas2 transcription, heme biosynthesis, and GATA-1 regulation of other vital constituents of the erythroid cell transcriptome. Bypassing Alas2 function in Alas2 cis-element-mutant (double mutant) cells by providing its catalytic product 5-aminolevulinic acid (5-ALA) rescued heme biosynthesis and the GATA-1-dependent genetic network. We discovered a GATA factor- and heme-dependent circuit that establishes the erythroid cell transcriptome. Overall design: G1E-ER-GATA-1 WT and double mutant cells were examined. Untreated WT, beta-estradiol-treated WT, beta-estradiol-treated double-mutant, and beta-estradiol/5-ALA-treated double-mutant cells were subjected to RNA-seq.

Description
Activation of telomerase often endows cancer cells, but rarely normal somatic cells, with immortality. Especially, fetal lung fibroblasts are known to be hardly immortalized by TERT overexpression. We here established an immortal non-transformed lung fibroblast cell line only by TERT transfection, as well as an immortal transformed cell line by transfection of TERT and SV40 early antigens. Comparing the expression profiles of these cell lines with those of mortal cell strains with elongated lifespan after TERT transfection, 51 genes, including 19 upregulated and 32 downregulated, were explored to be the candidates responsible for regulation of cellular proliferation of lung fibroblasts. These included the genes previously reported to be involved in cellular proliferation, transformation, or self-renewal capacity, and those highly expressed in lung tissues obtained from patients with idiopathic pulmonary fibrosis or hypersensitivity pneumonitis. This set of lung fibrobrast cell lines/strains of identical genetic background with different proliferative capacity, mortal and immortal non-transformed fibroblasts may become useful model cells for research on lung fibroblast growth regulation and the candidate genes explored in this study may provide promising biomarkers or molecular targets of pulmonary fibrosis.
