To explore if genic expression of beta(1)- or beta(2)-adrenoceptors (ARs) exhibits a common regulatory pattern with G protein-coupled receptor kinase (GRK) 2, GRK3, or GRK5 expression, we determined messenger RNA levels for these genes in different tissues from human and animal models of cardiovascular disease. We measured genic expression by qRT polymerase chain reaction in the left and right ventricles or peripheral blood mononuclear cells from healthy (n = 21), hypertensive (n = 20), heart failure (n = 24), and heart transplanted patients (n = 17) or in left ventricle, peripheral blood mononuclear cells, and kidney from spontaneously hypertensive rats or L-N-methyl-arginine-induced hypertensive rats and their respective controls (n = 4-5). In diseased versus healthy subjects and rats, parallel changes in messenger RNA levels of GRK2 and beta(2)-AR or GRK5 and beta(1)-AR were observed in each territory. Therefore, without excluding other regulatory mechanisms, the parallelism observed suggests a common regulatory pattern for the beta(1)-AR/GRK5 and beta(2)-AR/GRK2 genes, which is independent of cellular type or pathology. This highlights the need to focus not only on GRKs but also on beta(1)- or beta(2)-AR changes to completely understand the involvement of beta-AR/GRK pathways in cardiovascular diseases.
