Expression and prognostic value of BDH2 in GC. a, b Studies in the Oncomine and UALCAN database showed lower mRNA expression of BDH2 in GC tissues. c Expression levels of BDH2 protein were detected in 10 matched GC samples by western blotting (N, normal tumour-adjacent tissue; T, tumour tissue). d Quantification of BDH2 expression in GC tissues and adjacent normal tissues. e Expression of BDH2 was analysed by a TMA including 171 GC cases. Typical images are shown. Scale bars, 50 μm. f IHC quantification scores of BDH2 expression levels. g Kaplan–Meier survival curves illustrating the overall survival and disease-free survival of patients with GC associated with BDH2 expression (p < 0.001)
