Abstract excerpt
Our previous transgenic analyses revealed that a 600-base pair beta-myosin heavy chain (betaMyHC) promoter conferred mechanical overload (MOV) and non-weight-bearing (NWB) responsiveness to a chloramphenicol acetyltransferase reporter gene. Whether the same DNA regulatory element(s) direct betaMyHC expression following MOV or NWB activity in vivo remains unknown. We now show that a 293-base pair betaMyHC promoter...
