Research Abstract |
Fibrodysplasia ossificans progressiva(FOP) is a genetic disorder of dysregulated cellular differentiation which causes fibrous tissue(including muscle, tendon, and ligament) to be ossified when damaged. The mutations were identified in the activin A receptor, type I(ACVR1), a BMP type-1receptor. This study was purposed to establish the transgenic medaka fish that can induce overexpression of the ACVR1or BMP4gene by heat-shock in any target time points, tissues and cells. I established heat-shock inducible Cre recombinase expressing transgenic medaka fish(hsp70b :: Cre) using endogenous hsp70promoter and Cre inducible myogenic cells specific ACVR1expressing transgenic fish(DES :: lGlBMP4). However, both of heat-shock treated and non-treated double transgenic medaka fishes(hsp70b :: Cre and DES :: lGlBMP4) exhibited FOP like phenotypes, which mean endogenous hsp70 promoter was expressed continuously at a low level without heat induction. Then I combined the dual promoter expressing system and artificial heat-shock promoter and established heat-inducible double transgenic medaka fish(8xHSE :: Cre x DES : lGlACVR1).
