(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...

(Submitter supplied) Through small RNA sequencing, we finded that a total of 8 miRNAs, including miR-133a-3p and miR-1a-3p cluster, showed differential expression after guanidineacetic acid supplement. To further study the function of miR-133a-3p and miR-1a-3p in guanidineacetic acid induce myotube hypertrophy, we transfected miR-133a-3p and miR-1a-3p mimics, that also induce myotube hypertrophy. Through bioinformatics and dual-luciferase reporter system, the target gene of miR-133a-3p and miR-1a-3p were respectively determined. more...

(Submitter supplied) The acquisition of a proliferating cell status from a quiescent state as well as the shift between proliferation and differentiation are key developmental steps in skeletal-muscle stem cells (satellite cells) to provide proper muscle regeneration. However, how satellite-cell proliferation is regulated, though, is not fully understood. Here, we report that the c-isoform of the transcription factor Pitx2 increases cell proliferation in myoblasts by down-regulating the miRNAs miR-15b, miR-23b, miR-106b, and miR-503. more...

(Submitter supplied) We newly identified skeletal muscle differentiation-associated miRNAs by comparing miRNA expression profile between C2C12 cell and Wnt4-overexpressing C2C12 cell. miR-487b, miR-3963 and miR-6412 are significantly down-regulated in differentiating C2C12 cells, and transfection of their mimics resulted in reduced expression of myogenic differentiation markers including Troponin T, myosin heavy chain fast and slow type.

(Submitter supplied) Dental pulp cells (DPCs) are known to be enriched in stem/progenitor cells but not well characterized yet. Small non-coding microRNAs (miRNAs) have been identified to control protein translation, mRNA stability and transcription, and have been reported to play important roles in stem cell biology, related to cell reprogramming, maintenance of stemness and regulation of cell differentiation. In order to characterize dental pulp stem/progenitor cells and its mechanism of differentiation, we herein sorted stem-cell-enriched side population (SP) cells from human DPCs and periodontal ligament cells (PDLCs), and performed a locked nucleic acid (LNA)-based miRNA array. more...

(Submitter supplied) The differentiation and regeneration of skeletal muscle from myoblasts to myotubes involves myogenic transcription factors, such as myocardin-related transcription factor A (MRTF-A) and serum response factor (SRF). In addition, post-transcriptional regulation by miRNAs is required during myogenesis. Here we provide evidence for novel mechanisms regulating MRTF-A during myogenic differentiation. Endogenous MRTF-A protein abundance and activity decreased during C2C12 differentiation, which was attributable to miRNA-directed inhibition. more...

(Submitter supplied) Adult muscle stem cells show a high transcriptional and clonal heterogeneity during ageing. Whether microRNAs contribute to this diversity is not known. Here we use tissue-specific genetic deletion of microRNA (miR)-501 that is highly enriched in activated myogenic progenitor cells to address this question. Single-cell sequencing revealed a novel subpopulation of committed myogenic progenitor cells in miR-501 knockout mice that express high levels of terminal differentiation markers and inflammatory genes such as CD74. more...

(Submitter supplied) Objective: Decreased muscle mass is a major contributor to age-related morbidity, and strategies to improve muscle regeneration during ageing are urgently needed. Our aim was to identify the subset of relevant microRNAs (miRNAs) that partake in critical aspects of muscle cell differentiation, irrespective of computational predictions, genomic clustering or differential expression of the miRNAs. Methods: miRNA biogenesis was deleted in primary myoblasts using a tamoxifen-inducible CreLox system and combined with an add-back miRNA library screen. more...

(Submitter supplied) BACKGROUND: Development of the neural tube is a highly orchestrated process relying on precise, spatio-temporal expression of numerous genes as well as hierarchies of signal transduction and gene regulatory networks. Disruption of expression of a number of genes participating in these networks is believed to underlie developmental anomalies such as neural tube defects (NTDs) resulting from anomalous neural tube morphogenesis. more...
