The role of extrarenal renin in Goldblatt hypertension.
Renin-like activity can be demonstrated in arterial extracts from normal rats and from rats with Goldblatt hypertension. We have found no evidence, however, for elevated arterial renin levels in relation to plasma renin activity. Studies of the reversal of renovascular hypertension indicate that the fall in blood pressure produced by renal artery deconstriction is not renin-dependent. However, molecular biological techniques indicate that extrarenal renin gene expression is altered in some tissues, such as the adrenal gland in Goldblatt hypertension, and it is possible therefore that extrarenal renin synthesis is important in blood pressure control. This has to be distinguished from renin derived from plasma uptake.
