STING signaling contributes to methotrexate-induced liver injury by regulating ferroptosis in mice.

Methotrexate (MTX), an anti-metabolite agent, is a widely used chemotherapeutic anticancer drug, but its hepatotoxicity severely limits its clinical application. Nevertheless, the precise mechanisms of MTX-caused liver damage are extremely intricate and still need to be fully clarified. In the current study, we investigated the role of the STING-ERS-ferroptosis axis in MTX-triggered hepatic toxicity in vivo and in vitro models.

Possible sarcopenia: early screening and intervention-narrative review.

Sarcopenia is a new geriatric syndrome that has become a heavily researched topic, and it is a potential risk factor for weakness, disability, and death in elderly people. As the world's population ages, the incidence of sarcopenia has also increased, which has resulted in a series of health problems and in large medical costs. Although there are generally accepted diagnostic criteria for sarcopenia, the existing criteria require a comprehensive evaluation of muscle quality, muscle strength and muscle function.
