AI Article Synopsis
- Current research highlights the role of noncoding RNAs (ncRNAs) in regulating protein-coding gene expression, particularly in the differentiation of mouse MSCs into myocyte-like and cardiomyocyte-like cells.
- 5-AZA treatment of C3H10T1/2 cells successfully induced the formation of myotube-like structures and upregulated key genes related to muscle differentiation, while RNA sequencing revealed thousands of differentially expressed lncRNAs, mRNAs, and circRNAs.
- The findings underscore the significant involvement of ncRNAs in the differentiation processes and identify multiple signaling pathways associated with this regulation.
Article Abstract
Background: Currently, a heterogeneous category of noncoding RNAs (ncRNA) that directly regulate the expression or function of protein-coding genes is shown to have an effect on the fate decision of stem cells. However, the detailed regulatory roles of ncRNAs in myogenic and cardiomyogenic differentiation of mouse C3H10T1/2 mesenchymal stem cells (MSCs) are far from clear.
Methods: In this study, 5-azacytidine- (5-AZA-) treated C3H10T1/2 cells were differentiated into myocyte-like and cardiomyocyte-like cells. Next, ncRNA associated with myogenic and cardiomyogenic differentiation was identified using high-throughput RNA sequencing (RNA-seq) data. Bioinformatics analysis was conducted to identify the differentially expressed ncRNAs and the related signaling pathways.
Results: Myotube-like structure was formed after 5-AZA treatment of C3H10T1/2 cells. In addition, myogenic and cardiomyogenic differentiation-related genes like , , , and were upregulated significantly after the 5-AZA treatment. Totally, 1538 differentially expressed lncRNAs and 3398 differentially expressed mRNAs were identified, including 1175 upregulated and 363 downregulated lncRNAs and 2429 upregulated and 969 downregulated mRNAs. In addition, 46 differentially expressed circRNAs were identified, including 25 upregulated and 21 downregulated circRNAs. Moreover, the differentially expressed mRNAs were enriched into 5 significant pathways, including those for focal adhesion, ECM-receptor interaction, PI3K-AKT signaling pathway, PPAR signaling pathway, and Tyrosine metabolism.
Conclusions: A systematic view of the expression of ncRNAs in myogenic and cardiomyogenic differentiation of MSCs was provided in the study.

RNA-binding proteins are critically involved in the post-transcriptional control of gene expression during embryonic development and in adult life, contributing to regulating cell differentiation and maintaining tissue homeostasis. Compared to the relatively well documented functions of transcription factors, the regulatory roles of RNA-binding proteins in muscle development and function remain largely elusive. However, deficiency of many RNA-binding proteins has been associated with muscular defects, neuromuscular disorders and heart diseases, such as myotonic dystrophy, amyotrophic lateral sclerosis, and cardiomyopathy.

Article Synopsis
- - Cardiac muscle damage leads to the loss of cardiomyocytes (CMs) and heart failure, a leading cause of death globally, highlighting the urgent need for therapies that promote heart regeneration.
- - Current heart regeneration strategies focus on generating new functional CMs from existing cells, requiring a deep understanding of the processes involved in CM commitment and differentiation.
- - The review emphasizes the role of microRNAs in CM differentiation, showcasing how both positive and negative regulatory mechanisms are crucial for effective cardiac regeneration in adults.

Article Synopsis
- Statins (like Rosuvastatin, Simvastatin, and Pravastatin) enhance the growth and activation of cardiac stem/progenitor cells (CSCs) in both lab settings (in vitro) and in animal models after a heart attack (myocardial infarction).
- Specifically, Rosuvastatin treatment increases CSC numbers, promotes their differentiation into heart muscle cells, and helps repair heart tissue after damage.
- These findings suggest that statins could play a beneficial role in heart disease treatment by improving the regeneration of heart cells through their effects on CSCs and related cellular pathways.
