TP73 and neoplasm: Since these cell lines were previously reported to predominantly express TP63 (ΔNp63α), TP73 (TP73α), and TP53 [27,46,47], we further found that CA2, PMA, and ILQ induced the expression and phosphorylation of TP53 family members in these tumor cell lines (SCC-11, U87-MG, and RKO).
