Using reverse transcription-polymerase chain reaction (RT-PCR), Wang et al. [11] found that BAG2 was induced by proteasome inhibitors in cancer cell lines derived from different histology samples, including undifferentiated thyroid cancer, colon cancer, human fibrosarcoma, HeLa cervical cancer, breast cancer, ovarian cancer, pancreatic cancer, hepatic cancer, lung cancer, kidney cancer and SH-SY5Y neuroblastoma cell lines. This evidence concerns the gene BAG2 and cancer.
