The research pupose is to dissect the role of BAP1 and regulation of BAP1 in HCC. The dataset include BAP1 expression in HCC tumor tissue and non-tumour normal livers detected by qPCR, RNA-sequencing, IHC and from TCGA-LIHC; BAP1 mutation rate in different cohort (TCGA-LIHC and in-house); proportion analysis of different BAP1 mutation types.
