pRb family expression in mouse T-antigen-negative (A) and -positive (B) PNET cells and in mouse T-antigen-negative (R503; A) and -positive (R503/T; B) fibroblasts. The relative protein levels of pRb/p105, p107, and pRb2/p130 were detected by Western blotting using 40 μg of whole lysate. The expression of α-tubulin protein was assessed to normalize protein loading (ppRb2/p130, phosphorylated protein; pRb2/p130, hypophosphorylated protein).
