Then, to confirm the tumour phenotype, immunohistochemistry (IHC) (Figure S1) was utilised to qualitatively assess a panel of common ovarian cancer diagnostic markers, such as calretinin, E-cadherin, paired-box 8 (Pax8), antigen KI-67 (Ki-67) and tumour protein P53 (p53) (Figure S1), with expression summarised in Table S5. The gene discussed is TP53; the disease is ovarian carcinoma.
