(Submitter supplied) Biogenesis of canonical microRNAs (miRNAs) involves multiple steps: nuclear processing of primary miRNA (pri-miRNA) by DROSHA, nuclear export of precursor miRNA (pre-miRNA) by Exportin 5 (XPO5), and cytoplasmic processing of pre-miRNA by DICER. To gain a deeper understanding of the contribution of each of these maturation steps, we deleted DROSHA, XPO5, and DICER in the same human cell line, and analyzed their effects on miRNA biogenesis. more...

(Submitter supplied) XPO5 mediates nuclear export of miRNA hairpin precursors in a RanGTP-dependent manner. However, the requirement of XPO5 for global miRNA biogenesis and mammalian development and XPO5-associated RNA species are not determined. Here we show that XPO5 is required for mouse embryonic development and morphogenesis of skin and brain. Loss of XPO5 compromises the biogenesis of most miRNAs and that leads to severe developmental defects. more...

(Submitter supplied) Clinical skin manifestations are common in diabetes; however, molecular mechanisms underlying such defects are largely unknown. Several findings indicate a role for microRNA (miRNA) in skin homeostasis. We investigated whether miRNA expression is altered in the skin of a Type 1 mouse model of diabetes. For this purpose, miRNA profiling by microarray analysis was performed on RNA extracted from the skin of diabetic mice and non-diabetic controls. more...

(Submitter supplied) Macrophage activation must be tightly controlled to prevent overzealous responses that cause self-damage. MicroRNAs have been shown to promote classical macrophage activation by blocking concomitant anti-inflammatory signals and transcription factors, but can also place restraints on activation by preventing excessive TLR-signalling. In contrast, the microRNA profile associated with alternatively activated macrophages and their role in regulating wound-healing or anti-helminthic responses has not yet been described. more...

(Submitter supplied) MicroRNAs (miRNAs) are short noncoding RNA molecules regulating the expression of mRNAs. Target identification of miRNAs is computationally difficult due to the relatively low homology between miRNAs and their targets. We provide data here utilizing an experimental approach to identify targets of mmu-miR-378-3p, where mmu-miR-378-3p was overexpressed and silenced in NIH-3T3 murine fibroblasts and compared to control RNA transfected cells (RISC-free siRNA). more...

(Submitter supplied) Cell cycle arrest in response to DNA damage is an important anti-tumorigenic mechanism. microRNAs (miRNAs) were shown recently to play key regulatory roles in cell cycle progression. For example, miR-34a is induced in response to p53 activation and mediates G1 arrest by down-regulating multiple cell cycle-related transcripts. Here we show that genotoxic stress promotes the p53-dependent up-regulation of the homologous miRNAs, miR -192 and miR-215. more...

(Submitter supplied) To find regulated genes during peak inflammation of rheumatoid arthritis (RA), we have collected synovium from mouse Serum Transfer Arthtitis (STA) model at day 0 (Non Arthritic) and day 10 (Peak Inflammation). Serum transfer arthritis was induced in 12-week-old male C57BL/6J mice (The Jackson Laboratory) by intraperitoneal injection of 150 μl of arthritogenic serum on days 0, 2, and 7. Nonarthritic mice received 150 μl of sterile phosphate buffered saline at each time point.

(Submitter supplied) MicroRNAs (miRNAs) are short (~22 nucleotides) regulatory RNAs that can modulate gene expression and are aberrantly expressed in many diseases including cancer. We wanted to quantify the levels of endogenous miRNAs in pre-transfected HEY ovarian cancer cells to identify the highly expressed miRNAs. It was previously established that transfection of small RNAs can globally perturb gene expression, and one mechanism responsible for such alterations may involve de-repression of targets of endogenous miRNAs because of the saturation of the RISC complexes by the exogenously administered small RNA (Khan et al., 2009. more...

(Submitter supplied) MicroRNAs (miRNAs) are short (~22 nucleotides) regulatory RNAs that can modulate gene expression and are aberrantly expressed in many diseases including cancer. Previous studies have shown that miRNAs inhibit the translation and facilitate the degradation of their targeted mRNAs making them attractive candidates for use in cancer therapy. However, the potential clinical utility of miRNAs in cancer therapy rests heavily upon our ability to understand and accurately predict the consequences of fluctuations in levels of miRNAs within the context of complex tumor cells. more...
