Western blot analyses also implied that the PAH‐induced high expression of WIPF1, ETS1 and RhoA was inhibited by suppression of PAXIP1‐AS1, and inhibition of RhoA by fasudil also led to inhibition of the expression of WIPF and ETS1 (Figure 6E). The gene discussed is PAXIP1; the disease is pulmonary arterial hypertension.
