abstractText | Acetaldehyde and malondialdehyde react covalently with cellular proteins forming protein-malondialdehyde-acetaldehyde adducts thus modulating their biochemical functions. Alpha-2 macroglobulin, an acute phase protein produced by liver binds to cytokines, growth factors and neutralizes proteinases. In this study we examined the formation of MAA adducts of N-terminal and bait region of mouse A2M and their effect on modulating its proteinase and TGF-beta1 binding activities. Adduct formation abrogated the binding of bait region with TGF-beta1, trypsin, and elastase. TGF-beta1 induced NO production was also suppressed. Acetaldehyde and MDA adduction of A2M may have physiological consequences in alcoholic patients.
