in the cultured cells , as in the adult heart in vivo , expression of cardiac alpha-actin ( cact ) predominated over that of skeletal alpha-actin ( sact ) mrna , the fetal/neonatal isoform . alpha 1-adrenergic receptor stimulation induced hypertrophy of these cells , increasing total rna and cytoskeletal actin mrna by 1.8-fold over control , and total alpha-actin mrna by 4.3 fold .
