Also, data from the human protein atlas, which is a Swedish-based program initiated in 2003 with the aim to map all the human proteins in cells, tissues and organs using integration of various omics technologies [15], seems to confirm that ovarian carcinomas are PSMA negative cancers (see: https://www.proteinatlas.org/ENSG00000086205-FOLH1/pathology/ovarian+cancer). Here, FOLH1 is linked to cancer.
