Vechetti Lab

Overview

The Vechetti Lab focuses on understanding the complex mechanisms governing skeletal muscle regulation across various physiological and pathological conditions.

Our research encompasses four primary areas: 

  1. miRNAs and metabolism: Investigating how miRNAs and metabolic pathways affect muscle mass, function, and aging.
  2. Muscle Atrophy: Exploring the mechanisms governing skeletal muscle mass, including disuse-induced atrophy, sarcopenia, and cachexia.
  3. Hibernation: Utilizing natural hibernating animals, we investigate the effects of long-term of muscle disuse and obesity during torpid periods.
  4. Extracellular vesicles: The laboratory also explores muscle-derived extracellular vesicles.

Through this multifaceted approach, the Vechetti Laboratory aims to advance our understanding of skeletal muscle biology and potentially develop new therapeutic strategies for muscle-related disorders.
