Researchers identified three age-related proteins that may play key roles in PH progression as possible treatment targets.

A lack of the protein beta-arrestin 1 reduces the ability of pulmonary arteries to widen, leading to pulmonary hypertension, a study found.

Proteins are the building blocks of life. These biomolecules comprise chains of amino acids that fold into precise shapes to ...

Changes in pH make the protein open and close in different environments A close look at one protein shows how it moves molecular passengers into cells in the kidneys, brain and elsewhere. The protein ...
