21por Chen, Hao, Untiveros, Gustavo M., McKee, Laurel A. K., Perez, Jessica, Li, Jing, Antin, Parker B., Konhilas, John P.“…METHODOLOGY/PRINCIPAL FINDINGS: Using a mouse model of hypertrophic cardiomyopathy (HCM), we demonstrated early elevation of miR-195 and miR-451 in HCM hearts, which targets MO25, a central component of the MO25/STRAD/LKB1 complex that acts as an upstream kinase for AMPK. …”

24“…Functionally, overexpression of STARD13 inhibited cells stemness and enhanced 5-FU sensitivity in HCC cells. Mechanistically, STRAD13 overexpression suppressed RhoGTPase signaling and thus inhibited transcriptional factor YAP translocation from nuclear to cytoplasm, leading to the downregulation of transcriptional activity of YAP. …”

As a result, PA-S14 promotes AMPK activation, triggers autophagosome maturation, and increases autophagic flux. …”
