In order to continue evaluating the role of oxidative stress in the labor process, we next tested whether term premature rupture of the membranes (PROM) is also associated with increased susceptibility of maternal serum lipids to copper induced peroxidation.
Having successfully established the cascade process, we next initiated the synthesis of -chimonanthine and its related natural dimeric HPI alkaloids.
Given the importance of CLIP during the epitope selection process, we next asked whether the dependence of DM catalysis on the nature of the exchange peptide would be observed with CLIP prebound in the peptide binding groove.
As previous studies suggest that HSF1 is regulated by nucleocytoplasmic shuttling and that nuclear export is an important component in this process, we next examined the potential role of the principal exportin, CRM1/exportin-1 in PKAcα-regulated localization of HSF1 under control and stress conditions.
Since resistance to apoptosis is an essential step for the tumorigenesis process, we next examined the effect of the MPA mediated necrotic signal on different tumor cells demonstrating various mechanisms of resistance to apoptosis (Bcl2-, HSP70-, Lyn-, BCR-ABL overexpressing cells).
Because TRAF1 recruits TRAF2 and cIAPs to activate the anti-apoptotic process, we next measured the transcript levels of TRAF2 and cIAP2 genes.
As insulin signaling pathway has been reported to be involved in the aging process, we next assessed the cardiac levels of phosphorylated Akt and IGF-1, the key mediators of the insulin signaling pathway.
Having shown that TGF β indirectly induces the expression of these pro-apoptotic target genes and that E2F1 is required for this process, we next sought to determine whether E2F1 expression itself was regulated by TGF β.
To determine the role of the proteasome in this process, we next repeated these experiments and found that the MuRF2-mediated decrease in PPARγ1 could be prevented by adding the proteasome inhibitor MG132 (Fig. 6d).
In order to confirm that the regulation of key genes involved in macrophage cholesterol uptake is Smad-dependent, and to determine if Smad-2 and Smad-3 play distinct roles in this process, we next examined the transcript levels of CD36, LPL and SR-A in our Smad depleted, TGF-β stimulated virally infected system.
