CSX/Nkx2.5 transcription factor plays a pivotal role in cardiac development; however, its role in development and differentiation of other organs has not been investigated. In this study, we used C2C12 myoblasts and human fetal primary myoblasts to investigate the function of Nkx2.5 in skeletal myogenesis. The expression levels of Nkx2.5 decreased as C2C12 myoblasts elongated and fused to form myotubes. The expression of human NKX2.5 in C2C12 myoblasts inhibited myocyte differentiation and myotube formation, and up-regulated Gata4 and Tbx5 expression. The expression of NKX2.5 in terminally differentiated C2C12 myotubes resulted in a change in morphology and breakdown into smaller myotubes. Furthermore, overexpression of NKX2.5 in C2C12 cells and primary cultures of human fetal myoblasts led to differentiation of myoblasts into neuron-like cells and expression of neuronal markers. This study sheds light on the previously unknown non-cardiac functions of Nkx2.5 transcription factor.

Objective: Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder that significantly impairs muscle regeneration following injuries, contributing to numerous complications and reduced quality of life. There is an urgent need for therapeutic strategies that can enhance muscle regeneration and alleviate these pathological mechanisms. In this study, we evaluate the therapeutic efficacy of W-GA nanodots, which are composed of gallic acid (GA) and tungstate (W6+), on muscle regeneration in type 2 diabetes mellitus (T2D)-induced muscle injury, with a focus on their anti-inflammatory and antioxidative effects.

Recently, toxicological and epidemiological research has provided strong support for the unfavorable effects of bisphenol-A (BPA, 2,2'-bis(4-hydroxyphenyl) propane) on myogenesis and its underlying mechanisms. Researchers have therefore been looking for new strategies to prevent or mitigate these injurious effects of BPA on the human body. It has been found that plant extracts may act as potential therapeutic agents or functional foods, preventing human diseases caused by BPA.

Puerarin, a flavonoid compound present in the roots of radix , contributes to the development of tissues such as bone and nerve, but its role in skeletal muscle regeneration remains unclear. In this study, we employed C2C12 myoblasts and barium chloride (BaCl)-based muscle injury models to investigate the effects of puerarin on myogenesis. Our study showed that puerarin stimulated the migration and differentiation of myoblasts in vitro.

An actin-binding protein, known as Calponin 3 (CNN3), modulates the remodeling of the actin cytoskeleton, a fundamental process for the maintenance of skeletal muscle homeostasis. Although the roles of CNN3 in actin remodeling have been established, its biological significance in myoblast differentiation remains largely unknown. This study investigated the functional significance of CNN3 in myogenic differentiation, along with its effects on actin remodeling and mechanosensitive signaling in C2C12 myoblasts.

Developing scaffolds supporting functional cell attachment and tissue growth is critical in basic cell research, tissue engineering, and regenerative medicine approaches. Though poly(ethylene glycol) (PEG) and its derivatives are attractive for hydrogels and scaffold fabrication, they often require bioactive modifications due to their bioinert nature. In this work, biomimetic synthesized conductive polypyrrole-poly(3,4-ethylenedioxythiophene) copolymer doped with poly(styrenesulfonate) (PPy-PEDOT:PSS) was used as a biocompatible coating for poly(ethylene glycol) diacrylate (PEGDA) hydrogel to support neuronal and muscle cells' attachment, activity, and differentiation.
