Because dephosphorylated (activated) pRB blocks transition from G1 to S phase of the cell cycle whereas phosphorylated (inactivated) pRB releases this growth arrest, we characterized the role of pRB in IL-6 -mediated MM cell growth .
 ( protein: dephosphorylated (activated) pRB, None) , ( protein: pRB, None) , ( protein: IL-6, None) , ( protein: pRB, None) , ( protein: phosphorylated (inactivated) pRB, None) , ( protein: pRB, None)
