PIK3R2 and cancer: In contrast, the ALDO gene PIK3R2 (phosphoinositide-3-kinase, regulatory subunit 2 (beta)) was upregulated in all three cancer nodules: x(PTA→NOR) = 3.31 (CUT(PTA→NOR) = 1.89, p(PTA→NOR) = 0.013), x(PTB→NOR) = 1.85 (CUT(PTB→NOR) = 1.82, p(PTB→NOR) = 0.046), x(CWM→NOR) = 3.30 (CUT(CWM→NOR) = 1.90, p(CWM→NOR) = 0.032).
