Multifaceted roles of GSK-3 and Wnt/beta-catenin in hematopoiesis and leukemogenesis: opportunities for therapeutic intervention

2013

Glycogen synthase kinase-3 (GSK-3) is well documented to participate in a complex array of critical cellular processes. It was initially identified in rat skeletal muscle as a serine/threonine kinase that phosphorylated and inactivated glycogen synthase. This versatile protein is involved in numerous signaling pathways that influence metabolism, embryogenesis, differentiation, migration, cell cycle progression and survival. Recently, GSK-3 has been implicated in leukemia stem cell pathophysiology and may be an appropriate target for its eradication. In this review, we will discuss the roles that GSK-3 plays in hematopoiesis and leukemogenesis as how this pivotal kinase can interact with mul…

Study on b-Catenins mechanisms of regulation in zebrafish blastula embryo

2012

Background: â-catenin is a central component of the cadherin cell adhesion complex but also it plays an essential role in the canonical-Wingless/Wnt signaling pathway. In vertebrates, one of the initial steps for the establishment of the correct dorso-ventral (D/V) pattern in the embryo is the cytoplasmic accumulation followed by nuclear localization of â-catenin in the cells of the prospective dorsal side of the embryo. In zebrafish there are two â-catenins, 92,7% identical. The mutant fish line Ichabod (ich), with a mutation in the region of the â-catenin2 promoter that causes a decrease in the maternal accumulation of â-catenin2 protein in the embryos, fail to nuclear localize â- catenin…
