(Submitter supplied) MicroRNAs (miRNAs) are small noncoding RNAs that negatively regulate gene expression post-transcriptionally. They play a critical role in developmental and physiological processes and have been implicated in the pathogenesis of several diseases including cancer. To identify miRNA signatures associated with different stages of neoplastic development, we examined the expression profile of 776 primate miRNAs in the following cells: primary African green monkey kidney (pAGMK) cells; spontaneously immortalized, non-tumorigenic, low-passage VERO cells (10-87 LP); tumorigenic, high-passage VERO cells (10-87 HP); and a cell line (10-87 T) derived from a 10-87 HP cell tumor xenograft in athymic nude mice. more...

(Submitter supplied) Study designed to obtain microRNA profile of tumorigenic Sca-1+CD34+ cells during the formation of pulmonary adenocarcinoma. After intranasal infection with adenovirus CRE (Ad-Cre), lung adenocarcinoma was identified pathologically in Lox-stop-lox Kras (LSL-Kras) G12D mice. Sca-1+CD34+ cells were sorted by flow cytometry and tested for the tumor-initiating ability to undergo self-renewal and differentiation. more...

(Submitter supplied) Cancer-associated fibroblasts (CAFs) promote tumor progression through several mechanisms. MicroRNAs (miRNAs) play a key role in CAFs tumor-promoting properties, however, their role in CAFs from different topological areas in lung cancer progression remains unclear. This study aimed to characterize the miRNA expression profile of fibroblasts isolated from matched tumor front (F-CAFs), inner tumor (In-CAFs), and normal adjacent tissue (NFs) in lung adenocarcinoma, using microarray analysis and RT-qPCR. more...

(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) We aimed to identify microRNAs which are altered upon EpCAM silencing.EpCAM is over expressed molecule in Retinoblastoma. Retinoblastoma Y 79 cell line was used as model to study the differential expression of microRNA in EpCAM siRNA treated cells.To validate technique we further confirmed deregulated expression of few microRNAs in Y 79 cells using Real Time PCR technique.

(Submitter supplied) Using cross-species analysis, we have previously shown that the miR-137 and the miR-23b microRNA cluster are upregulated in the more aggressive and metastatic, mouse and human, primary tumors, designated as met-like primary (MLP). In order to identify miRNA target genes, we overexpressed the miRNAs in an inducible manner in the insulinoma-like ßTC3 cells and performed RNA-seq.

(Submitter supplied) Purpose: MicroRNAs (miRNAs) are non-coding small miRNA ~22 nucleotides in length and play a vital role in muscle development by binding to messenger RNAs (mRNAs). Large White (LW, a lean type pig) and Meishan pigs (MS, a Chinese indigenous obese breed) have significant postnatal phenotype differences in growth rate, muscle mass and meat quality, and theses difference are programmed during prenatal muscle development.To shed directly light on the miRNA transcriptome difference in prenatal muscles between these two distinct pig breeds. more...

(Submitter supplied) MicroRNAs (miRNAs) are important in the regulation of many biological processes such as growth and development. To evaluate the role of miRNAs in skeletal muscle regeneration, global miRNA expression was measured during muscle cell growth and differentiation. Primary cultures of murine myogenic progenitor cells (MPC) were studied for miRNA expression using quantitative PCR-array. During MPC differentiation or proliferation, 139 or 16 miRNAs, respectively, exhibited significant >2-fold changes. more...
