Hormone replacement and current anti-hypertensive therapies do not correct this post-menopausal increased risk suggesting a distinct pathogenic framework. We investigated the hypothesis that distinct genetic determi...
متن کاملGenetic background of pancreatitis.
Trypsin activity is properly suppressed by pancreatic secretory trypsin inhibitor (PSTI), which is also known as serine protease inhibitor Kazal type 1 (SPINK1), thereby preventing damage to pancreatic acinar cells as a first line of defence. However, if trypsin activation exceeds the capacity of PSTI/SPINK1, a subsequent cascade of events leads to the activation of various proteases that damag...
