In addition, the authors observed an improvement in mitochondrial function due to increased levels of PGC-1α, mitofusin 2 (Mfn2), dynamin-related protein 1 (Drp1) and PTEN-induced kinase 1 (PINK1), confirming it as a valid strategy for counteracting sarcopenia and preserving muscle health during aging [99]. The gene discussed is PINK1; the disease is sarcopenia.
