The Effect of Leaf Extract on C2C12 Myoblast Proliferation and Redox Status Under Oxidative Insult.

Skeletal muscle tissue can regenerate after damage through the action of satellite cells, which proliferate as myoblasts when activated. Oxidative stress, marked by high rates of reactive oxygen species (e.g.

Effects of 12-week power training on bone in mobility-limited older adults: randomised controlled trial.

Unlabelled: This study examines how power training affects estimated bone strength, revealing that females benefit more than males, especially in the upper limbs (radius). These findings highlight the importance of designing sex-specific exercise programs to enhance bone health. Further research is needed to optimize training duration and address site-specific differences.

Sexual Dimorphism in Sex Hormone Metabolism in Human Skeletal Muscle Cells in Response to Different Testosterone Exposure.

Muscle tissue is an important target of sex steroids, and particularly, testosterone plays essential roles in muscle cell metabolism. Wide ranges of studies have reported sex differences in basal muscle steroidogenesis, and recently several genes have been identified to be regulated by androgen response elements that show innate sex differences in muscle. However, studies accounting for and demonstrating cell sexual dimorphism in vitro are still scarce and not well characterized.

Exploring the Impact of Exercise-Derived Extracellular Vesicles in Cancer Biology.

Cancer remains a major challenge in medicine, prompting exploration of innovative therapies. Recent studies suggest that exercise-derived extracellular vesicles (EVs) may offer potential anti-cancer benefits. These small, membrane-bound particles, including exosomes, carry bioactive molecules such as proteins and RNA that mediate intercellular communication.
