Simultaneous Pharmacologic Inhibition of Yes‐Associated Protein 1 and Glutaminase 1 via Inhaled Poly(Lactic‐co‐Glycolic) Acid–Encapsulated Microparticles Improves Pulmonary Hypertension

Background Pulmonary hypertension (PH) is a deadly disease characterized by vascular stiffness and altered cellular metabolism. Current treatments focus on vasodilation and not other root causes of pathogenesis. Previously, it was demonstrated that glutamine metabolism, as catalyzed by GLS1 (glutaminase 1) activity, is mechanoactivated by matrix stiffening and the transcriptional coactivators YAP1 (yes-associated protein 1) and transcriptional...
