Blocking RNA MALAT1 Reduces Heart Abnormality in Pulmonary Hypertension, Study Shows
Eliminating a long noncoding RNA reduced heart-muscle enlargement in mice with pulmonary hypertension (PH), according to a study. The RNA, known as MALAT1, balances the turnover — or production, growth and death — of smooth muscle cells lining blood vessels. MALAT1 stands for metastasis-associated lung adenocarcinoma transcript 1. The study, “…
