Figure 5From: Phorbol myristate acetate and Bryostatin 1 rescue IFN-gamma inducibility of MHC class II molecules in LS1034 colorectal carcinoma cell lineExpression of the Rb protein in four tumor cell lines. Rb expression is not lost in weakly inducible LS1034 colon carcinoma (D) and MSTO-211H mesothelioma (F). Rb expression is also preserved in the non-inducible HepG2 hepatocellular carcinoma (G). Panels A-C show the experimental setup for measuring Rb-specific cellular fluorescence by flow cytometry.Back to article page
