Post-hypoxic injuries in plants are primarily caused by bursts of reactive oxygen species and acetaldehyde. In agreement with previous studies, we found accumulations of acetaldehyde in rice during re-aeration following submergence. During re-aeration, acetaldehyde-oxidizing aldehyde dehydrogenase (ALDH) activity increased, thereby causing the acetaldehyde content to decrease in rice. Interestingly,...
We studied the mechanism by which 9,13-di-cis-retinoic acid (9,13dcRA), a novel and endogenous stereoisomer of all-trans-RA, induces TGF-β formation in a human liver stellate cell line, LI90. 9,13dcRA induced the expression of RARα and RARβ, enhanced the production of tissue-type plasminogen activator (tPA), thereby, surface plasmin levels, and induced the activation of latent TGF-β. Similar effects...
