More Info
Glycogen synthase kinase-3 beta (GSK3b) is a multifunctional serine/threonine kinase which was originally identified as a regulator of glycogen metabolism. It plays a key role in the regulation of numerous signalling pathways including cellular process such as cell cycle, inflammation and cell proliferation.

Biological target:
CHIR-99021 trihydrochloride (CT99021 trihydrochloride) is a potent and selective GSK-3α/β inhibitor with IC50s of 10 nM and 6.7 nM.
In vitro activity:
Organoids treated with low dose of CHIR 99021 (1μM) showed increased levels of neural progenitor cell (NPC) markers SOX2 (WB, 1.5-fold increase) and PAX6 (IHC, 1.8-fold increase), and of radial glia marker BLBP (WB, 2.1-fold increase). No change was observed for levels of neuroepithelium marker E-cadherin and neuronal markers TUJ1 and DCX. In contrast, organoids treated with 10μM CHIR 99021 showed increased levels of E-cadherin (WB and IHC, 1.8-fold and 92-fold increase) and of intermediate progenitor marker TBR2 (2.9-fold increase), decreased levels of NPC markers SOX2 (WB, 1.9-fold decrease) and PAX6 (IHC, 2-fold decrease), and decreased levels of neuronal marker DCX (IHC, 7.8-fold decrease). This suggests that GSK3β signaling modulates neuroepithelium differentiation in a dose dependent manner.

In vivo activity:
Phosphorylated GSK3β (p-GSK3β, Tyr216) protein levels were higher in ischemic regions of hearts from Lrp5-/- mice than in those from Wt mice (Fig 1A). Total GSK3β protein levels were also increased in the myocardium of Lrp5-/- mice compared to Wt mice. Phosphorylated GSK3β/Total- GSK3β ratios to analyze total myocardial content of activated GSK3β found no differences between genotypes (Fig 1A). CHIR99021 treatment significantly reduced p-GSK3β protein levels in Lrp5-/- mice but not in Wt mice. CHIR99021 treatment reduced p-GSK3β to the same level in both genotypes. Induction of myocardial injury (MI) causes a highly significant increase of p-GSK3β protein levels in Wt and Lrp5-/- mice, strongly suggesting that injury affects the canonical Wnt pathway (Fig 1B). Treatment with CHIR99021 before occlusion significantly reduced p-GSK3β levels in both genotypes (Fig 1C) further demonstrating efficacy of CHIR99021 treatments. Indeed, levels of p-GSK3β protein were significantly reduced after CHIR99021 treatments in damaged hearts leaving the canonical pathway open for activation and for β-catenin interaction with specific transcription factors.
