“…These genes are related to muscle degeneration and are inhibited by miR‐133; therefore, downregulation of this miRNA results in muscle degeneration (Giakoumaki et al, 2022). On the other hand, different subtypes of miR‐133, including miR‐133b‐3p, miR‐133a‐3p and miR‐133c are upregulated in the serum of sarcopenic male Sprague‐Dawley rats (W. Yu, Yang, et al, 2022). Expression of miR‐133a is also upregulated in C57BL/6 mice and mice C2C12 cell line (Soriano‐Arroquia, House, et al, 2016).…”
