GSK3B and cancer: To further detect the effects of GSK3β on LCRMP-1(WT)-induced cancer cell invasion, lentivirus expressing GFP control, GSK3β (WT), GSK3β (CA), or GSK3β (KD) were infected in CL1-0/LCRMP-1 overexpression cells (lines 1015 and 1003) which have been previously shown to strongly induce cell invasiveness [10].
