"Results BAP1 promotes proliferation in HNSCC cells regardless of HPV status Studies of the effects of BAP1 on cell proliferation have shown conflicting results , with some reporting that BAP1 suppresses cell proliferation ( 12 , 13 ) , and others reporting that BAP1 enhances proliferation ( 14 , 15 ) ."

"One intact allele of the BAP1 gene on chromosome 3 is requisite for the expression and translocation to the nucleus where BAP1 can inhibit tumor proliferation. xref Suppression of the nuclear localization of BAP1 (biallelic suppression) occurs in monosomy 3 because it is combined with assorted mutations on the remaining allele that may truncate the BAP1 protein, or affect nuclear localizer regions. xref BAP1 has definite additional prognostic value compared to the aforementioned tests and unlike the other prognostic tests permits microscopic confirmation of tumor."

"An analysis of multiple lung cancer cell lines identified a cell line with biallelic inactivation suggesting that BAP1 may be a two-hit tumor suppressor gene. xref Subsequently, BAP1 overexpression was shown to inhibit proliferation, and this effect was compromised by mutations disrupting catalytic activity or nuclear localization. xref However, the inhibition of cell proliferation by BAP1 is cell type specific. xref , xref , xref In NCI-H226, where BAP1 suppresses cell proliferation, ectopic BAP1 expression also inhibited tumor formation in xenografts. xref "

"These results indicated that BAP1 suppressed ICC cell proliferation, cell cycle progression, and invasion via inhibiting ERK1/2 and JNK/c-Jun signaling pathways.To further validate these findings, we used inhibitors of the ERK1/2 pathway (U0126) and JNK/c-Jun pathway (SP600125) in RBE-shBAP1 cells."

"A previous study on the expression of BAP1 tumor suppressor gene in 1222 patients with TCGA breast cancer data reported that the expression of BAP1, which enhances BRCA1-mediated suppression of cell proliferation through BRCA1 stabilization, is highly correlated with USP19 expression."

"Although paradoxical for a gene whose genetic alterations support a tumor suppressor function, these data are consistent with previous studies of non MPM cell lines in which BAP1 knockdown caused proliferation defects with an accumulation of cells in S phase XREF_BIBR - XREF_BIBR."
reach
"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]."
reach
"As in 769-P cells, (i) cell proliferation was inhibited by wild-type BAP1 and substantially less so by an HBM mutant, (ii) the HBM mutant reduced H2Aub1 levels, (iii) BAP1 cofractionated with HCF-1, and (iv) restoration of BAP1 protected UMRC6 cells against genotoxic death (XREF_SUPPLEMENTARY)."

"BAP1 binds to HCF-1 in renal cancer cell lines. xref BAP1 binding was demonstrated through reciprocal immunoprecipitation experiments, and most BAP1 protein co-fractionated with HCF-1 by gel filtration chromatography. xref BAP1 binding to and co-fractionation with HCF-1 was also observed in orthotopic tumorgrafts in mice directly derived from surgically removed tumors of patients. xref Consistent with previous observations, xref immunoprecipitations of BAP1 and HCF-1 deplete BAP1 protein to a similar extent suggesting that most BAP1 is bound to HCF-1 (at least in cells reconstituted with BAP1). xref Binding to HCF-1 is important for BAP1-supression of cell proliferation. xref BAP1 reintroduction into two different BAP1-deficient ccRCC cell lines reduced cell growth. xref The inhibition of cell proliferation by BAP1 was compromised by disruption of the HCF-1 binding motif. xref Taken together these data suggest that BAP1 binding to HCF-1 is important for its tumor suppressor function in renal cancer."
