We further validated the increased expression of LIPA in OCa using IHC with the LIPA antibody by employing a tissue microarray (TMA) consisting of 21 serous, 44 mucinous, 22 endometrioid adenocarcinoma, 3 clear cell carcinoma tumors and 5 normal/benign ovarian tissues. This evidence concerns the gene LIPA and endometrioid adenocarcinoma.
