Gα-protein detection in human vascular SMCs and rat AoSMCs. Shown are representative Western blots of Gα-protein expression in human PASMCs and rat AoSMCs and a table illustrating the presence of Gα subunits expressed in various HCMV-permissive cell types, including PASMCs, CASMCs, U373MG, and NHDFs as well as cell types commonly used in signal transduction studies, COS7 and rat AoSMCs.
