STAT3 and cancer: , this prescription has been shown to elimination of DNA damage in hydrogen peroxide-induced auditory HCs, blocks up-regulation of cellular senescence proteins p21 and p-p53, increases p-ERK (ERK, extracellular regulated protein kinase) expression, reduces p-STAT3 (STAT3 activation is closely related to cancer) expression [171], and protects cochlear cells from ototoxicity caused by gentamicin [172].
