A similar pattern was seen in pulmonary arterioles, where the number of p65+ EC (86.4±3.28 versus 4.7±2.3 in controls) and PASMC (39.2±5.3 in PAH versus 6.39±2.61 in controls) was significant higher in PAH (p<0.0001 for both, Figure 6b). The gene discussed is RELA; the disease is pulmonary arterial hypertension.
