TP53 and neoplasm: Similar as the BRCA1 and BRCA2 tumor suppressors, expression of OTUD1 was significantly suppressed by wild-type HRAS in p53 null MCF10A cells, but not in the control MCF10A cells (p53-wt), indicating that gain of oncogenic RAS together with loss of p53 tumor suppressor could lead to decreased OTUD1 function (GSE81593) (Fig. 8c).
