Higher levels of chloride in pulmonary artery smooth muscle cells (PASMCs) may contribute to the development of pulmonary hypertension (PH) after exposure to low oxygen (hypoxia), a study in a rat model suggested. The study, “Increased intracellular Cl− concentration in pulmonary arterial myocytes is associated with chronic hypoxic…
“When we’re headed toward an outcome that’s too horrible to face, that’s when we go looking for a second opinion. Sometimes, the answer we get just confirms our worst fears. But sometimes, it can shed new light on a problem. Make you…
Inhibition of proteins that regulate gene expression — called BET — were found to ease pulmonary hypertension (PH) in a rat model of chronic obstructive pulmonary disease (COPD), a study reports. The study, “Inhibition of BET Proteins Reduces Right Ventricle Hypertrophy and Pulmonary Hypertension Resulting from Combined…
Sildenafil appears to treat pulmonary hypertension (PH) by reducing the recruitment of bone marrow (BM)-derived progenitor cells, cells now being seen as potential key drivers of lung remodeling and inflammation in diseases that include PH. The study, “Sildenafil attenuates hypoxic pulmonary remodelling by inhibiting bone marrow progenitor cells,” was published in the…
