PKN3 and invasive breast carcinoma: Taken together, the cross‐correlation analysis of the transcriptomic and phosphoproteomic data showed a positive correlation between PKN3 and p130Cas expression in invasive breast carcinoma and prostate adenocarcinoma tumors, and positive correlation between PKN3 activity and the level of p130Cas phosphorylation on Ser428 in invasive breast carcinoma tumors.
