Elevated levels of corticipotropin-releasing hormone (CRH) may predict preterm delivery and shorter gestation lengths in pregnant women. The study found that higher CRH levels at 28-30 weeks gestation were associated with earlier deliveries and increased risk of preterm birth.
Cornell University researchers discovered how chronic stress intensifies the adrenaline response by controlling the structure of donut-shaped protein channels on adrenal cells. This 'molecular memory' can be influenced by lifestyle factors, paving the way for gene therapy and potential treatments for hypertension and heart attacks.
A team of researchers at Northwestern University and the Mayo Clinic have identified two new proteins, Cyp-40 and p23, that act as molecular chaperones to fold proteins into an intermediate state. This discovery expands our understanding of what molecular chaperones are and their role in enhancing hormone sensitivity in cells.
