Summary: Monocytes/macrophages and vascular smooth muscle cells (vSMCs) play key roles in atherosclerosis development and exhibit plasticity in response to environmental changes; vSMCs can switch from a contractile to a secretory phenotype and display macrophage characteristics, contributing to foam cell formation in atherosclerotic plaques. Nitric oxide levels impact molecular pathways involved in these processes, suggesting potential therapeutic targets for further exploration.

Summary: The study found that levels of tetrahydrobiopterin were low in Duchenne muscular dystrophy patients and mdx mice, but could be restored to normal levels by overexpressing dystrophin. Tetrahydrobiopterin deficiency in mdx mice was likely due to lower levels of sepiapterin reductase in skeletal muscle. Supplementation with tetrahydrobiopterin improved skeletal muscle function and cardiac pathology in mdx mice.

Summary: The study demonstrated that water extract of medical ink (WEMI) had no cytotoxic effect on murine macrophage Raw264.7 cells and slightly rescued LPS-suppressed cell viability. WEMI did not induce NO production or IL-6 secretion, but significantly induced secretion of TNF-alpha. Additionally, WEMI effectively reduced LPS-induced NO production.

Summary: This study reveals that pharyngeal muscles have high levels of active HGF, which drives the basal proliferation of SCs. FAPs are the major cell type providing HGF in pharyngeal muscles. Additionally, activated SCs with large cell size and increased mitochondrial content were found in pharyngeal muscles, providing new insights into the distinctive activity of pharyngeal SCs.

Summary: Pelvic floor muscle injury during childbirth is a key risk factor for pelvic floor disorders. Muscle stem cells, fibro-adipogenic progenitors, and immune cells play important roles in the regeneration of injured pelvic floor muscles. The loss of function and decreased expansion of muscle stem cells and fibro-adipogenic progenitors after birth injury lead to impaired pelvic floor muscle recovery.

Summary: Magnesium plays a pivotal role in maintaining skeletal muscle health and optimizing performance. Deficiency in magnesium can decrease muscle strength and affect muscle behavior and metabolism. Nitric oxide appears to be a key player in these effects. Understanding these mechanisms can help improve muscle conditions associated with magnesium deficiency.

Summary: In this study, we performed myopathologic analysis on muscle biopsies from DMD patients and found an increase in fibro-adipogenic progenitors, which contribute to fibrotic progression and lipid deposition. At the same time, there was a decline in muscle regenerative capacity, which was strongly correlated with compromised activation and expansion of muscle stem cells. Additionally, our study revealed an early acquisition of a senescence phenotype by DMD-afflicted muscle stem cells. These findings highlight the importance of muscle stem cell senescence as a pivotal readout for future therapeutic interventions.

Summary: DMD is a devastating muscle degenerative disease with no effective cure. Defective expression of the DMD gene and impaired muscle stem cell function contribute to the progression of the disease. Restoring muscle stem cell function may serve as a viable regenerative medicine strategy to mitigate DMD.

Summary: Muscle stem cells (MuSCs) undergo fate decisions regulated by chromatin-modifying enzymes and myogenic transcription factors. Chromatin topology plays a role in shaping the 3D genome architecture of MuSCs and maintaining cell identity. Defects in epigenetic control contribute to the pathogenesis of muscle diseases.

Summary: Macrophages play crucial roles in inflammation and immune responses. Current methods for macrophage culture are not suitable for studying nitric oxide biology and redox mechanisms. This study presents an optimized protocol to control the NO-redox environment and maintain cell growth and differentiation conditions, allowing for reproducible experiments.

Summary: The structure of the broiler breast muscle has changed in modern commercial broilers, with increased muscle fiber diameters, decreased circulatory supply, and decreased connective spacing between fibers. Satellite cells, responsible for muscle growth and repair, have been found to undergo changes that limit their ability to regenerate damaged muscle fibers. These cellular changes are likely linked to myopathies such as Wooden Breast.

Summary: Our understanding of the complexity of the developing hematopoietic system has greatly increased in recent decades. We now know that multiple HSC-independent progenitor populations during fetal development play vital roles that can affect adult physiology and lead to disease. Ontogeny has been shown to be a primary determinant of the function of critical cell types.
