Regulation of HSY on TGF-β1/Smads signaling pathway and MMPs system in irradiated rats. A low dose (0.31 ml/d, LDG), medium dose (0.62 ml/d, MDG), and high dose (1.24 ml/d, HDG) of HSY were given daily to irradiated rats. (a) The protein expression of TGF-β1, Col1, and Col3 in irradiated rats was analyzed with western blotting. (b) The protein expression of Smad 2, Smad 3, Smad 4, and Smad 7 in irradiated rats was analyzed with western blotting. (c) The protein expression of MMP14 and TIMP1 in irradiated rats was analyzed with western blotting. The average fluorescence intensity of each protein band is shown. All data are representative of three independent experiments. ##p<0.01 versus Con; p<0.05 versus 25 Gy; p<0.01 versus 25 Gy.
