BCL2 and hepatocellular carcinoma: To gain some insight into the expression pattern of BCL-2 family protein, we tested in untreated HCC samples (<5cm) without vascular invasion (I-II TNM stage) from Ethanol/HCV cirrhotic patients (n=12) for mRNA changes respect to adjacent non-tumoral biopsies (n=12) and to healthy livers (n=10), as detailed in Supplementary Figure 3.
