Using RT-qPCR, we investigated the expression of well characterized p53 target genes PMAIP1 (NOXA), CDKN1A (p21), TP53I3 (PIG3), SESN1, as well as ZMAT3 (Wig-1) and TP53INP1 which have been recently highlighted as major effectors of p53-mediated tumor suppression [23, 24] (Fig. 2d-e). Here, CDKN1A is linked to neoplasm.
