Ment merge and / or on a common final pathway. Our results also show that some of the protective effect against the cytotoxicity can t crocidolite are mediated by the mTOR pathway, in line with the conclusions of Wilson and colleagues65 who mediated this Flt Signaling signaling mTOR survival of small sample reported primary mesothelioma Re cultured ex vivo. Our studies, however, was the protection Similar in all clones, suggesting that neither add nor calretinin in the mTOR-mediated protection were involved. Closing Lich has the ERK signaling pathway has also been reported to play an R In the conversion of asbestos fibers in the mesothelial cells66 and pERK mediation as a new molecular Therapieans Tze target.
67 was proposed Conversely, the absence of differences in activation of ERK in reactive mesothelium and malignant mesothelioma was an argument Henzi et al 2334 in exchange for a share transformation CHIR-258 uses benign tumors of b best sartigen mesothelium.68 Our results showing this latter term: they show that inhibition of ERK had no negative impact on the acute cytotoxicity t studied in our study. In summary, the overexpression of calretinin in mesothelial cells immortalized largely replicate the cytoprotective effects observed in SV40 transfected clones. In both cases Is the activation of the PI3K/AKT signaling pathway in the increased Hte survival rate after exposure to asbestos. Since calretinin is expressed in almost all asbestos mesothelioma, observed 27.
28 and here shown that transfection with a SV40 early gene region is sufficient to can the expression of calretinin, big e levels of this protein to increased Hen k in mesothelial cells what the underlying cause common to an increase increase the resistance of the signals are input into the rule cell death. In this way, influenced mesothelial cells escape senescence to collect additionally, USEFUL mutations leads closing Lich completely to a Converted ndig. Mechanisms calretinin selectively blocks the function and / or down-regulation of its expression as a strategy can mpfen to oppose the development of mesothelioma k Be considered. In view of the fact that mesotheliomagenesis is a very slow process, the engagement at a point a long time at the first exposure still be of therapeutic importance. Ver changes Of phosphoinositide 3-kinase / Akt / mammalian target of rapamycin signaling pathway in many human tumors found.
In particular, the amplification of PIK3CA and mutation, the mutation PIK3R and act, and counteract the loss of PTEN tumor suppressor in constitutive activation of this signaling pathway. This fully understand the interactions between signaling molecules in PI3K/Akt/mTOR is gr Ter importance. Two distinct mTOR complexes, mTORC1 and mTORC2, have been identified and their sensitivity to rapamycin. mTORC1 is behind the act, rapamycin sensitive to inhibition and controlled the protein translation cap dependent dependent. The two most studied substrates are mTORC1 40S ribosomal S6 kinase 1 and eukaryotic translation initiation factor 4E binding protein 1, to mediate efficient protein translation. In contrast, mTORC2 immediately prior act and is best YOUR BIDDING against rapamycin. Akt can be activated by the phosphoinositide by phosphorylation at two sites, T308 and S473 by mTORC2
