AMPK activator acadesine fails to alleviate isoniazid-caused mitochondrial instability in HepG2 cells

690 views | Dec 04 2018

Zhang TG et al. showed that AMPK activator acadesine (AICAR) alleviated INH-caused impairment of mitochondrial biogenesis by activation of silent information regulator two ortholog 1 (SIRT1)-peroxisome proliferator-activated receptor γ coactivator 1α (PGC1 α) pathway in HepG2 cells.
