Multi-omics signature in vervet leg muscle: middle-aged versus older females
In vastus lateralis muscle of female vervet monkeys, a multi-omics signature distinguished middle-aged animals with normal gait speed from older animals with declining gait speed. [1]
Automatic summary · not editorially reviewed
The key findings
Vastus lateralis muscle from female vervet monkeys was compared between middle-aged animals with normal gait speed and older animals with declining gait speed. [1]
Integrating transcriptome, miRNome and methylome data yielded a signature that sharply distinguished the two groups. [1]
The findings are described as associated with impaired muscle function during aging and as potential mechanisms and targets, not proven causes. [1]

Vervet leg muscle: middle-aged versus older females
The researchers studied the vastus lateralis muscle, a thigh muscle, from female vervet monkeys (Chlorocebus aethiops sabaeus). They compared middle-aged animals with normal gait speed against older animals whose gait speed was declining. The abstract links age-related loss of skeletal muscle function, often seen as slower gait speed, to frailty and loss of independence.

Transcriptome, miRNome and methylome combined
The team examined coordinated changes across three molecular layers: the transcriptome, the miRNome and the methylome. Integrating these layers produced a signature that sharply separated the two groups. It involved miR-181a-5p, miR-320b and miR-425 controlling SYNCRIP, miR-193b-3p regulating MCL1 and PLAU, a multi-omic network governing ZNF274 and ANP32E, and altered mRNA levels such as VEZT. Functional annotation linked the miRNA signatures, with inverse expression of their mRNA targets, to skeletal muscle biology, metabolism and possible immune-inflammation mechanisms.

Abstract-only scope of the vervet muscle findings
The abstract describes an interconnected network of epigenetic, post-transcriptional and transcriptional alterations associated with impaired muscle function during aging. It presents these molecules as potential mechanisms and targets, not as proven causes or tested interventions. The abstract does not report sample sizes, follow-up or effect estimates, and the full text was not reviewed. These are animal and molecular findings, not evidence of human lifespan or muscle benefit.
