Does overexpression of protein kinase C-beta1 isoenzyme suppress indomethacin-induced apoptosis in gastric epithelial cells?
Indomethacin-induced apoptosis in gastric cancer cells is partly mediated by differential regulation of PKC isoform expression. Enhanced expression of exogenous PKC-beta1 protects against indomethacin-induced apoptosis through up-regulation of p21(waf1/cip1).
Although alloimmune inflammation is required to initiate airway disease, alcohol primes the allograft for greater TGF-beta(1) expression, myofibroblast transdifferentiation, and fibrosis than by alloimmune inflammation alone. This has serious clinical implications, as many lung donors have underlying alcohol abuse that may prime the allograft recipient for subsequent OB.
