reach
"The results of this study suggest that inhibiting USP8 promotes the degradation of FGFR2 via the proteasome, leading to suppression of STAT3 signaling in ARID1A-deficient OCCCs and subsequent induction of apoptosis.Since approximately half of OCCCs carry ARID1A-deficient mutations, synthetic lethal therapy using the USP8 inhibitors identified in this study could become a crucial personalized treatment approach."

reach
"Then, suppression of USP8 explicitly promotes the degradation of FGFR2 in ARID1A-deficient cells, and the STAT3 pathway, which is its downstream pathway, was suppressed, resulting in synthetic lethality by induction of apoptosis.ARID1A-deficient cancers include a significant number of gastric cancers, biliary tract cancers, and pancreatic cancers ."
