TWIST1 and pulmonary arterial hypertension: Other transcription factors and co-factors (e.g., TFII-I, GATA2, YAP1) that sense mechanical forces interact with Twist1, control angiogenesis [47, 50, 71, 75, 88], and contribute to age-related lung diseases (e.g., pulmonary fibrosis, pulmonary hypertension) [85–87].
