Effects of GSK3-β Inhibitors on Wnt Signaling in Zebrafish Fin Regeneration: Chemical Biology

Abstract

In order to develop beneficial drugs for osteoporosis it is important to understand the molecular mechanisms of bone regeneration and define specific regulatory factors. Zebrafish can regenerate damaged tissues, and they prove to be a good model to study bone growth and repair. Previous research showed that GSK3β inhibitor compound at various concentrations and for different treatment periods effectively stimulated fin regeneration. Conducted experiments identified temporal and spatial fluctuations on individual gene markers after GSK3β inhibitor treatment at various concentrations. Recent analyzed data uses the Lilly Research Labs experimental compound LSN 2105786 at 3 nM and 5 nM to stimulate tissue regeneration to determine whether activating Wnt signaling produces cell proliferation and β-catenin translocation to the nucleus for zebrafish bone regeneration. This research has potential to identify mechanism of bone growth and repair, leading to more suitable drugs for patients suffering with osteoporosis.
