In the same study, inactivation of BAP1 in clear cell renal cell carcinoma cell lines altered cellular proteostasis, suppressed cell proliferation, and induced a mesenchymal‐to‐epithelial‐like phenotype [45], suggesting that the role of BAP1 in tumor progression may be more complex than its presumed tumor suppressor function [46]. This evidence concerns the gene BAP1 and neoplasm.
