Application

6-bromoindirubin-3′-oxime (BIO) has been used:
  • in MTT 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) cell proliferation assay
  • as a medium supplement in embryonic stem cells (ESCs)
  • for the inhibition of glycogen synthase kinase 3 β (GSK-3β) in human dermal papilla cells (hDPCs)

Biochem/physiol Actions

6-bromoindirubin-3′-oxime (BIO) is a potent, reversible and ATP-competitive GSK-3α/β inhibitor and the first pharmacological agent shown to maintain self-renewal in human and mouse embryonic stem cells. Human embryonic stem cells (hESCs) are maintained in the undifferentiated state through treatment with a GSK-3 inhibitor, BIO, under a feeder-free condition.

GTPase of immunity-associated protein 5 (Gimap5) is linked with lymphocyte survival, autoimmunity, and colitis, but its mechanisms of action are unclear. Here, we show that Gimap5 is essential for the inactivation of glycogen synthase kinase-3β (GSK3β) following T cell activation.
