Following the IH treatment, we measured the mRNA levels of angiotensinogen (AGT), angiotensin II receptor type 1 (AGTR1), angiotensin II receptor type 2 (AGTR2), renin (REN), and CD38 by means of a real-time reverse transcription polymerase chain reaction (RT-PCR). The gene discussed is AGT; the disease is isolated hemihyperplasia.
