... significantly increased. The results indicate that inhibition of the PI3K/Akt signaling pathway may lead to inhibition of the MDR induced by PrP C in gastric cancer cells. The mechanism underlying PI3K/Akt-mediated PrP C -induced ... in similar releasing rates to each other because of their toxicity effect (P > 0.05) (Fig. 3). The results indicated that inhibition...

Examination of the role of peroxide-derived radicals in enzyme inhibition To examine whether radical species were generated during the inactivation of GAPDH and L DH by ... inactivation of G APDH being metal- ion independent, whereas inhibition of GR and LDH by H 2 O 2 occurs most rapidly in the presence of metal ions. It is proposed t...

Our previous studies of the inhibitory effect of ... enzyme inhibition (compare 12 against 13 and 15 in Fig. 1). Following the preliminary screen, each of the four most promising inhibitors was used in further inhibi...

The validity of the results obtained for the binding of CaM to the N-terminus of hEAG1 channels was confirmed employing ... putative CaM binding domains in the channel protein. Indeed, we found two more sites, one in the C-terminus neigh- boring to the previously identified site and on...

A common feature of the regulation of the NF-jB family is their sequestration in the cytoplasm as inactive complexes with a class of inhibitory ... FSK did not inhibit TNFa-induced DNA-binding of NF-jB (Fig. 3D). Thus, it is likely that the inhibitory effect of PKA on NF-jB is not due to the inhibition of DNA-bind...
