The serine/threonine protein kinase B (PKB, also known as Akt) plays a pivotal role in diverse cellular functions. Elevated expression of activated Akt has been detected in a wide variety of human cancers; however, the mechanism of Akt protein stability regulation remains unclear. In this study, we showed a strong correlation between the expression levels(More)
Nonsteroidal analogues of 1alpha,25(OH)2D3, lacking either the full five-membered D ring (C-ring analogues) or the full six-membered C ring (D-ring analogues) are more potent inhibitors of cell proliferation or inducers of cell differentiation than is 1alpha,25(OH)2D3. Maximal superagonistic activity was seen for the C-ring analogue with a 24(R)-hydroxyl(More)
