Among the endometrial cancer cell lines Ishikawa H and Hec50co cells displayed the highest, nearly equal PLAC1 expression with Hec50co cells being 1.26-fold higher relative to Ishikawa H. KLE cells presented PLAC1 expression of −3.26-fold relative to Ishikawa H. Both ECC-1 and AN3CA cells were more than 80-fold lower than Ishikawa H, but neither RL95-2 nor SK-UT-1b cells presented any appreciable PLAC1 expression relative to the others. This evidence concerns the gene PLAC1 and endometrial cancer.
