A recent study suggests that RNA fragments called microRNAs (miRNAs), long thought of as genetic “junk,” actually control the production of endothelial cells, whose over-proliferation is responsible for the development of pulmonary hypertension (PH). The study, published in the Experimental Biology and Medicine journal, is titled “microRNA-125a in pulmonary hypertension: Regulator of a proliferative phenotype of endothelial cells.”
