background: the wnt/β- the wnt/β-catenin signaling pathway is involved in many developmental processes in both fetal and adult life; its abnormalities can lead to disorders including several types of cancers and malfunction of specific cells and tissues in both animals and humans. its role in reproductive processes has been proven. objective: this study was designed to evaluate the expression o...
background: salivary gland tumors (sgt) are rare lesions with uncertain histopathology. one of the major signaling pathways that participate in the development of several tumors is protein kinase a. in this pathway, glycogen synthase kinase β (gsk3β) and camp responsive element binding protein (creb3) are two genes which are supposed to be down regulated in most human tumors. the expression lev...
Purified preparations of rabbit skeletal muscle glycogen synthase (specific activity 6 to 42 units/mg of protein) were found to be contaminated with calciumdependent kinase(s) which catalyzed the phosphorylation of glycogen phosphorylase b and glycogen synthase. In a series of glycogen synthase preparations there was a correlation between the phosphorylation rates of glycogen synthase and of ad...
Background: Atrophy in skeletal muscle plays an important role in disease-related tissue dysfunction such as sarcopenia. The Wnt-signaling pathway has been shown to be critical for skeletal muscle development. Current evidence suggests that exercise trainings may alter hypertrophy-related signaling in skeletal muscle. Therefore, the purpose of this study was investigating the effect of three mo...
Kinases can phosphorylate and regulate androgen receptor activity during prostate cancer progression. In particular, we showed that glycogen synthase kinase-3 beta phosphorylates the androgen receptor, thereby inhibiting androgen receptor-driven transcription. Conversely, the glycogen synthase kinase-3 beta inhibitor lithium chloride suppressed the glycogen synthase kinase-3 beta-mediated phosp...
A rapid method for purifying glycogen synthase a from rat liver was developed and the enzyme was tested as a substrate for nine different protein kinases, six of which were isolated from rat liver. The enzyme was phosphorylated on a 17-kDa CNBr fragment to approximately 1 phosphate/87-kDa subunit by phosphorylase b kinase from muscle or liver with a decrease in the activity ratio (-Glc-6-P/+Glc...
A multifunctional protein kinase, purified from rat liver as ATP-citrate lyase kinase, has been identified as a glycogen synthase kinase. This kinase catalyzed incorporation of up to 1.5 mol of 32PO4/mol of synthase subunit associated with a decrease in the glycogen synthase activity ratio from 0.85 to a value of 0.15. Approximately 65-70% of the 32PO4 was incorporated into site 3 and 30-35% in...
Cardiac dysfunction is a severe secondary effect of Type 2 diabetes. Recruitment of the protein kinase B/glycogen synthase kinase-3 pathway represents an integral event in glucose homeostasis, albeit its regulation in the diabetic heart remains undefined. Thus the following study tested the hypothesis that the regulation of protein kinase B/glycogen synthase kinase-3 was altered in the myocardi...
