Does pregnancy induce an increase in the expression of glyceraldehyde-3-phosphate dehydrogenase in uterine artery endothelial cells?
Pregnancy increases the expression of both GAPDH mRNA and protein in UAEC. Furthermore, the pregnancy-induced increase in GAPDH protein in the endothelium of the uterine artery appears specific, as it is not observed in the omental (systemic) artery. This induction is not, however, reproduced in vitro with exogenous NO or angiogenic growth factor treatment (up to 24 hours).
Our results demonstrate down-regulation of renal chloride transporters/channels during sepsis, which is probably mediated by proinflammatory cytokines and accounts for the development of LPS-induced tubular dysfunction. Our findings contribute to the understanding, on one hand, the failure of single-anticytokine strategies and, on the other hand, the beneficial effects of glucocorticoids in the therapy of septic patients.
