Objective: MicroRNAs (miRNAs) are increasingly recognized as fine-tuning regulators of metabolism, and are dysregulated in several disease conditions. With their capacity to rapidly change gene expression, miRNAs are also important regulators of development and cell differentiation. In the current study, we describe an impaired myogenic capacity of muscle stem cells isolated from humans with type 2 diabetes (T2DM) and assess whether this phenotype is regulated by miRNAs.
Methods: We measured global miRNA expression during in vitro differentiation of muscle stem cells derived from T2DM patients and healthy controls.
Results: The mir-23b/27b cluster was downregulated in the cells of the patients, and a pro-myogenic effect of these miRNAs was mediated through the p53 pathway, which was concordantly dysregulated in the muscle cells derived from humans with T2DM.
Conclusions: Our results indicate that we have identified a novel pathway for coordination of myogenesis, the miR-23b/27b-p53 axis that, when dysregulated, potentially contributes to a sustained muscular dysfunction in T2DM.

Enterovirus A71 (EV-A71) is a major pathogen responsible for hand, foot, and mouth disease (HFMD) in infants and children. EV-A71 infection represents an epidemic in the Asia-Pacific region, and can cause serious central nervous system (CNS) infections in immunocompromised patients that can result in paralysis, disability, or death. There have been few reports in the literature concerning EV-A71 CNS infections after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in adult patients.

Background: Uterine injury can cause uterine scarring, leading to a series of complications that threaten women's health. Uterine healing is a complex process, and there are currently no effective treatments. Although our previous studies have shown that bone marrow mesenchymal stem cells (BMSCs) promote uterine damage repair, the underlying mechanisms remain unclear.

Research on bone substitutes for repairing bone defects has drawn increasing attention, and the efficacy of three-dimensional (3D) printed bioactive porous scaffolds for bone defect repair has been well documented. Our previous studies have shown that psoralen can promote osteogenesis by activating the Wnt/β-catenin and BMP/Smad signaling pathways and their crosstalk effects, and psoralen nanospheres have a good osteogenesis-promoting effect with low cytotoxicity. The Chinese medicine oyster shell powder, characterized by its porous structure, strong adsorption, and unique bioactivity, has potential in fracture-promoting repair materials.

The neuromuscular junction (NMJ) is essential for transmitting signals from motor neurons (MNs) to skeletal muscles (SKMs), and its dysfunction can lead to severe motor disorders. However, our understanding of the NMJ is limited by the absence of accurate human models. Although human induced pluripotent stem cell (iPSC)-derived models have advanced NMJ research, their application is constrained by challenges such as limited differentiation efficiency, lengthy generation times, and cryopreservation difficulties.

Sarcopenia, characterized by reduced muscle mass and strength, is associated with osteoarthritis (OA), particularly in middle-aged women, and may worsen postoperatively. Resistance exercise (RE) can resolve sarcopenia; however, recovery is often suboptimal. Nitrate (NO) supplementation may enhance muscle recovery and complement RE.
