Previous studies also described that TRAP1 protein is expressed in several cell lines, such as H1299 human non-small cell lung carcinoma [20,25], G361 melanoma [34], PC-3M prostate carcinoma [35], A549 human adenocarcinoma [20,25,36,37], SW480 colorectal adenocarcinoma [34], HL-60 promyelocytic leukemia [34], SH-SY5Y neuroblastoma [38], HCT116 colon cancer [6] and human cervix carcinoma HeLa cell lines [39]. This evidence concerns the gene TRAP1 and colonic neoplasm.
