Effects of hindlimb unloading on the mevalonate and mechanistic target of rapamycin complex 1 signaling pathways in a fast‐twitch muscle in rats

Autor: Munehiro Uda, Toshinori Yoshihara, Noriko Ichinoseki‐Sekine, Takeshi Baba

Publikováno v: Physiological Reports, Vol 12, Iss 5, Pp n/a-n/a (2024)

Abstract Fast‐twitch muscles are less susceptible to disuse atrophy, activate the mechanistic target of rapamycin complex 1 (mTORC1) signaling pathway, and increase protein synthesis under prolonged muscle disuse conditions. However, the mechanism

Publikováno v: Scientific Reports, Vol 13, Iss 1, Pp 1-10 (2023)

Abstract 4-hydroxytamoxifen (OHT) is an anti-cancer drug that induces apoptosis in breast cancer cells. Although changes in lipid levels and mitochondrial respiration have been observed in OHT-treated cells, the overall mechanisms underlying these me
