Fig. 3From: STAT3 as a potential therapeutic target in triple negative breast cancer: a systematic reviewInhibiting STAT3 signaling at multiple levels for cancer therapy. Currently, the majority of STAT3 inhibitors have been developed through (1) targeting the upstream regulators of STAT3, (2) binding to the SH2 domain of STAT3 and inhibiting its activation, (3) inhibiting STAT3 phosphorylation or acetylation, or (4) blocking STAT3-DNA binding. Other potential strategies, such as (5) inhibiting the binding of STAT3 with its co-activators, (6) modulating the binding of STAT3 with other interactive proteins, and (7) promoting STAT3 ubiquitination and proteasomal degradation may also be evaluated for developing novel STAT3 inhibitorsBack to article page
