Monocrotaline 12-25 SMAD family member 1 Rattus norvegicus 71-75 18367643-7 2008 MCT-treated rats also had increased expression of phosphorylated Smad 1 (P-Smad 1) but not phosphorylated Smad 2 (P-Smad 2). Monocrotaline 0-3 SMAD family member 1 Rattus norvegicus 65-71 18367643-7 2008 MCT-treated rats also had increased expression of phosphorylated Smad 1 (P-Smad 1) but not phosphorylated Smad 2 (P-Smad 2). Monocrotaline 0-3 SMAD family member 1 Rattus norvegicus 75-81
