Knockdown of USP9X suppressed basal activation from the Erk1/2 pathway, that was restored by exogenous manifestation of IRS-2 however, not by IGF-IR considerably, suggesting how the stabilization of IRS-2 by USP9X is crucial for basal Erk1/2 activation. Finally, we assessed anchorage-independent cell development, a characteristic tumor feature, by soft-agar colony development assay. Knockdown of USP9X reduced anchorage-independent cell development of prostate carcinoma cell range significantly. Taken altogether, our findings reveal that USP9X is necessary for the advertising of prostate tumor growth by keeping the activation from the Erk1/2 pathway through IRS-2 stabilization.
