Muscle aging is a complex physiological process that leads to the progressive decline in muscle mass and function, contributing to debilitating conditions in the elderly such as sarcopenia. In recent years, non-coding RNAs (ncRNAs) have been increasingly recognized as major regulators of muscle aging and related cellular processes. Here, we comprehensively review the emerging role of ncRNAs, including microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs), in the regulation of muscle aging. We also discuss how targeting these ncRNAs can be explored for the development of novel interventions to combat age-related muscle decline. The insights provided in this review offer a promising avenue for future research and therapeutic strategies aimed at improving muscle health during aging.

Background: Prior research linking myosteatosis with cognition in older adults has been conducted in relatively homogenous populations with narrow age ranges. We evaluated if abdominal myosteatosis was associated with processing speed in a multiethnic cohort of middle aged and older adults.
Methods: The sample included 1,268 adults (46-86 years-old, mean 63±9 years, 53 % female, 41 % White, 20 % Black, 14 % Chinese, and 25 % Hispanic), a subset from the Multi-Ethnic Study of Atherosclerosis.

With the growing interest in skeletal muscle diseases, understanding the processes, factors, and treatments associated with muscle regeneration is crucial. Skeletal muscle regeneration is a complex process that largely depends on the niche composed of cell populations, such as satellite cells, and their microenvironment. Cellular senescence is associated with various physiological processes and age-related diseases and plays a significant role in the muscle regeneration niche.

Collateral blood vessels are unique, naturally occurring endogenous bypass vessels that provide alternative pathways for oxygen delivery in obstructive arterial conditions and diseases. Surprisingly however, the capacity of the collateral circulation to provide protection varies greatly among individuals, resulting in a significant fraction having poor collateral circulation in their tissues. We recently reviewed evidence that the presence of naturally-occurring polymorphisms in genes that determine the number and diameter of collaterals that form during development (ie, genetic background), is a major contributor to this variation.

Background: Skeletal muscle wasting is commonly observed in aging, immobility, and chronic diseases. In pathological conditions, the impairment of skeletal muscle and immune system often occurs simultaneously. Recent studies have highlighted the initiative role of skeletal muscle in interactions with immune cells.

Costameres are essential for maintaining the integrity of muscle fibers, which affects the meat tenderness. To explore the pattern of alteration in costameres after slaughter, this study investigated the distribution of costamere proteins (desmin, talin-2, vinculin, and integrin β1), their impact on tenderness, and the involved enzymes. Western blot analysis showed that talin-2 significantly degraded in postmortem, while integrin β1 significantly increased at 48 h ( < 0.
