  • Publication number: 20210093693
    Abstract: Disclosed herein are a G-protein-coupled receptor (GPCR) kinase-interacting protein (GIT) and a use thereof. More particularly, a pharmaceutical composition for prevention or treatment of senescence or senescence-associated disease and a composition for inhibition of cellular senescence, each comprising GIT or a GIT activating agent as an active ingredient, a method for screening a cellular senescence inhibitor, and a method for inhibition of cellular senescence are provided. In senescent cells induced by down-regulation of bPIX expression, GIT or GIT-CT overexpression was found to reduce the expression of senescence markers and to suppress senescence-induced endocytosis reduction. Having an inhibitory activity against cellular senescence, GIT can be thus used as a novel therapeutic agent for senescence or senescence-associated disease.
