HIF1A and hepatocellular carcinoma: In addition, data from publicly available databases revealed a positive correlation between the mRNA level of BCLAF1 and HIF1A in 373 HCC patients (cBioportal [32, 33], Fig. 1g) and in 100 HCC patients (microarray database GSE62043 [34]; Fig. 1g), suggesting that BCLAF1 is highly expressed in tumor hypoxic microenvironment and correlated with HIF1A.
