To further investigate the potential role of SLC7A2 in age-related sarcopenia, we analyzed the expression of SLC7A2 during the aging process in public databases for humans skeletal muscle, available online: http://gb.whu.edu.cn/ADEIP or http://geneyun.net/ADEIP (accessed on 30 July 2022), and mouse skeletal muscle, available online: https://sarcoatlas.scicore.unibas.ch/ (accessed on 22 September 2022), skeletal muscle. This evidence concerns the gene SLC7A2 and sarcopenia.
