Downstream of growth factor receptors, signaling by the phosphoinositide 3 kinase (PI3K) pathway is known to play an important role in the growth and survival of many tumor types. The PI3K pathway simplistically comprises PI3K itself, followed by PDK-1, then AKT and finally glycogen synthase kinase 3 (GSK3). PI3K/AKT signaling promotes increased GSK3 phosphorylation, that is associated with red...
A fundamental challenge in treating disease is identifying molecular states that affect cellular responses to drugs. Here, we focus on glycogen synthase kinase 3 (GSK-3), a key regulator for many of the hallmark behaviors of cancer cells. We alter GSK-3 activity in colon epithelial cells to test its role in modulating drug response. We find that GSK-3 activity broadly affects the cellular sensi...
Psoriasis is a common, chronic skin disorder characterized by abnormal epidermal proliferation, dermal infiltration of inflammatory cells and increased angiogenesis. S-phase kinase-associated protein 2 (Skp2), the F-box component an SCF ubiquitin ligase complex, targets several cell cycle inhibitors for degradation oncogene implicated in types cancers. Here, we showed that Skp2 expression was b...
The effects of tail-vein insulin injection (2 U/kg) on the regulation of protein-serine kinases in hindlimb skeletal muscle were investigated in hyperinsulinemic hypertensive fructose-fed (FF) animals that had been fasted overnight. Basal protein kinase B (PKB) activity was elevated about twofold in FF rats and was not further stimulated by insulin. Phosphatidylinositol 3-kinase (PI3K), which l...
In recent studies we have demonstrated that glycogen synthase kinase 3beta (GSK3beta) and its substrate microtubule-associated protein 1B (MAP1B) regulate the microtubule cytoskeleton during axon outgrowth. To further examine the role GSK3beta plays in axon outgrowth we investigated the expression of GSK3beta and its activity towards MAP1B during nerve growth factor (NGF)-stimulated PC12 cell d...
Fibroblast growth factor (FGF) 19 is an enterokine synthesized and released when bile acids are taken up into the ileum. We show that FGF19 stimulates hepatic protein and glycogen synthesis but does not induce lipogenesis. The effects of FGF19 are independent of the activity of either insulin or the protein kinase Akt and, instead, are mediated through a mitogen-activated protein kinase signali...
A pyridocarbazole platinum complex, which matches the overall shape of the natural product staurosporine, binds with high affinity at the adenosine triphosphate binding site of glycogen synthase kinase 3 (GSK-3alpha).

Forty-eight mutants of Saccharomyces cerevisiae with defects in glycogen metabolism were isolated. The mutations defined eight GLC genes, the function of which were determined. Mutations in three of these genes activate the RAS/cAMP pathway either by impairment of a RAS GTPase-activating protein (GLC1/IRA1 and GLC4/IRA2) or by activating Ras2p (GLC5/RAS2). SNF1 protein kinase (GLC2) was found t...
