MicroRNA‑23a‑5p mediates the proliferation and differentiation of C2C12 myoblasts.

ABSTRACT: Skeletal myogenesis is a highly ordered and complex biological process that is mediated by numerous regulatory factors. In previous studies, it has been demonstrated that microRNAs (miRs) and long non‑coding RNAs (lncRNAs) serve key roles in skeletal myogenesis. The present study showed that the expression levels of miR‑23a‑5p showed a dynamic change from decrease to increase during C2C12 myoblast proliferation and differentiation. Functional analysis using 5‑ethynyl‑2'‑deoxyuridine proliferation and Cell Counting Kit‑8 detection assays indicated that overexpression of miR‑23a‑5p significantly promoted C2C12 myoblast proliferation compared with the negative control. In addition, in C2C12 myoblasts transfected with miR‑23a‑5p mimics, increased expression levels of regulators associated with
