MicroRNAs are a class of 18-22 nucleotide non-coding RNAs that modulate gene expression by associating with the 3' untranslated regions of mRNAs. A large number of microRNAs are involved in the regulation of myoblast differentiation, many of which remain undiscovered. In this study, we found that miR-143-3p was upregulated during C2C12 myoblast differentiation and over-expression of miR-143-3p significantly inhibited the relative expression levels of MyoD, MyoG, myf5, and MyHC genes, especially in the later stages of differentiation. In addition, miR-143-3p inhibited expression of genes involved in the endogenous Wnt signaling pathway during C2C12 myoblast differentiation, including Wnt5a, LRP5, Axin2, and β-catenin. These results indicate that miR-143-3p represents a new myogenic differentiation-associated microRNA that can inhibit C2C12 myoblast differentiation, especially in the later stages of differentiation.

UI MeSH Term Description Entries
D002454 Cell Differentiation Progressive restriction of the developmental potential and increasing specialization of function that leads to the formation of specialized cells, tissues, and organs. Differentiation, Cell,Cell Differentiations,Differentiations, Cell
D002460 Cell Line Established cell cultures that have the potential to propagate indefinitely. Cell Lines,Line, Cell,Lines, Cell
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D032446 Myoblasts Embryonic (precursor) cells of the myogenic lineage that develop from the MESODERM. They undergo proliferation, migrate to their various sites, and then differentiate into the appropriate form of myocytes (MYOCYTES, SKELETAL; MYOCYTES, CARDIAC; MYOCYTES, SMOOTH MUSCLE).

D035683 MicroRNAs Small double-stranded, non-protein coding RNAs, 21-25 nucleotides in length generated from single-stranded microRNA gene transcripts by the same RIBONUCLEASE III, Dicer, that produces small interfering RNAs (RNA, SMALL INTERFERING). They become part of the RNA-INDUCED SILENCING COMPLEX and repress the translation (TRANSLATION, GENETIC) of target RNA by binding to homologous 3'UTR region as an imperfect match. The small temporal RNAs (stRNAs), let-7 and lin-4, from C. elegans, are the first 2 miRNAs discovered, and are from a class of miRNAs involved in developmental timing.
