Multiple signaling pathways have been implicated in the hypertrophic response of ventricular myocytes, yet the importance of cell-matrix interactions has not been extensively examined. Integrins are cell-surface molecules that link the extracellular …
In cardiac myocytes, B-type natriuretic peptide (BNP) expression is induced with the rapid kinetics of a primary response gene. Like many other primary response gene transcripts, the BNP mRNA possesses destabilizing elements and is believed to be …
In response to hormones and mechanical stretch, neonatal rat ventricular myocytes exhibit a hypertrophic response that is characterized by induction of cardiac-specific genes and increased myocardial cell size. Hypertrophic stimuli also activate …
In the present study, cis elements in the 5'-flanking sequence (FS) of the rat atrial natriuretic factor (ANF) gene involved in regulating basal and alpha 1-adrenergic-inducible transcription were investigated. Truncation analyses using …
It has been shown recently that alpha-adrenergic agonists can stimulate atrial natriuretic factor (ANF) expression in ventricular cardiac myocytes; however, little is known about the intracellular signals mediating this activation. The present study …
