WebDec 13, 2024 · Cyclin-dependent kinases 4 and 6 (CDK4/6) drive cell proliferation by partnering with D-type cyclins (CycD) to phosphorylate the retinoblastoma protein (Rb). Rb is subsequently hyperphosphorylated and inactivated by CDK2 to trigger passage through the G 1 phase of the cell cycle ( 1 – 3 ). WebWe previously found that protein kinase C-β (PKC-β) expression in NCI H209 (209) SCLC cells increases markedly with c-myc transfection (L. F. Barr et al., Cancer Res., 51: 5514-5519, 1991), and we hypothesized that PKC-β may mediate some of the effects of c-myc in these cells. We test this hypothesis by transfection of rat PKC-β1 and bovine ...
