Skeletal muscle, a vital and intricate organ, plays a pivotal role in maintaining overall body metabolism, facilitating movement, and supporting normal daily activities. An accumulating body of evidence suggests that microRNA (miRNA) holds a crucial role in orchestrating skeletal muscle growth. Therefore, the primary aim of this study was to investigate the influence of on myogenesis. In our study, the overexpression of was found to stimulate proliferation while suppressing differentiation in C2C12 myoblasts. Conversely, the inhibition of expression yielded contrasting effects. Through bioinformatics analysis, potential binding sites of with the 3'UTR region of BTG anti-proliferative factor 2 () were predicted. Subsequently, dual luciferase assays conclusively demonstrated as the direct target gene of . Further investigation into the role of in C2C12 myoblasts unveiled that its overexpression impeded proliferation and encouraged differentiation in these cells. Notably, co-transfection experiments showcased that the overexpression of could counteract the effects induced by . In summary, our findings elucidate that promotes proliferation while inhibiting differentiation in C2C12 myoblasts by targeting .

Diacylglycerol kinase δ (DGKδ) phosphorylates diacylglycerol to produce phosphatidic acid. Previously, we demonstrated that down-regulation of DGKδ suppresses the myogenic differentiation of C2C12 myoblasts. However, the myogenic roles of DGKδ in vivo remain unclear.

N6-methyladenosine (mA), a well-known post-transcriptional modification, is implicated in diverse cellular and physiological processes. However, much remains unknown regarding the precise role and mechanism of mA modification on muscle development. In this study, we make observation that the levels of mA and METTL3 are markedly elevated during the differentiation phase (DM) compared to the growth phase (GM) in both C2C12 and bovine myoblasts.

Mammalian genome is hierarchically organized by CTCF and cohesin through loop extrusion mechanism to facilitate the organization of topologically associating domains (TADs). Mounting evidence suggests additional factors/mechanisms exist to orchestrate TAD formation and maintenance. In this study, we investigate the potential role of RNA-binding proteins (RBPs) in TAD organization.

Cells perceive external and internally generated forces of different kinds, significantly impacting their cellular biology. In the relatively nascent field of mechanobiology, the impact of such forces is studied and further utilized to broaden the knowledge of cellular developmental pathways, disease progression, tissue engineering, and developing novel regenerative strategies. However, extensive considerations of mechanotransduction pathways for biomedical applications are still broadly limited due to a lack of affordable technologies in terms of devices and simple magnetic actuatable materials.

Skeletal muscle aging poses a major threat to the health and quality of life of elderly individuals. Fisetin, a natural polyphenolic compound, exhibits various biological activities; however, its role in preventing skeletal muscle cell aging is still unclear. This study aimed to elucidate the effects of fisetin on skeletal muscle aging using a d-galactose-induced C2C12 myoblast senescence model.
