I have searched journal about effect Angiotensin Receptor Blocker like Candesartan etc to TGF beta 1 Expression or concentration in tissue artery or other organ, but I haven't get any journal, anyone can help?
Take a look at the publications of Wayne Border and Nancy Noble on ARB's, TGFb, and renal fibrosis. This may not be exactly what you are looking for, but should provide a window into the literature on the topic.
