In particular, the first 50 genes supported that the ubuquitin genes, such as UBB, UBC, EEF2, were related to the pathogenesis of MM.

Endogenous eEF2 from Saccharomyces cerevisiae strain TKY675 was replaced by a genomically integrated histagged analog (kindly provided by Terri Goss Kinzy, Piscataway, NJ) (18).
Both proteins were eluted with buffer containing 250 mmol/L imidazole, renatured by dialysis at 4 [degrees]C against 2 mol/L urea/10 mmol/L Tris (pH 7.4)/1 mmol/L reduced glutathione, twice against 20 mmol/L Tris (pH 7.4)/1 mmol/L EDTA, and twice against PBS (150 mM NaCl, 8.3 mM [Na.sub.2]HP[O.sub.4], 1.7 mM K[H.sub.2]P[O.sub.4], pH 7.4), concentrated as described above for eEF2 purification, and stored at -20 [degrees]C.
Elevated eEF2 phosphorylation has also been observed in cachectic mice bearing Murine adenocarcinoma 16 (MAC16) tumors [91].

As an important positive regulatory factor involving in the Met-mediated regulation of [beta]-case in translational elongation and secretion, RPL35 was found to control ribosome translational elongation during synthesis of [beta]-case by interacting with eukaryotic translational elongation factor 2 (eEF2) and that eEF2 was the signaling molecule downstream of RPL35 controlling this process [43].
A p70S6k, quando ativada, fosforila e inativa a enzima quinase do fator de elongacao 2 (eEF2K), fato este que permite que o eEF2 seja ativado, o que promove a elongacao.
CORM-2 prevented serum-induced eEF2 dephosphorylation, in a time-dependent manner and inhibited the PI3K-Akt-mTOR signalling pathway in PSCs, independently of the ERK1/2 signalling pathway, at concentrations of up to 100 [micro]M.
The housekeeping gene and its primers were as follows: EEF2 (fw): 5'-GAC ATC ACC AAG GGT GTG CAG-3' and EEF2 (rv): 5'-GCG GTC AGC ACA CTG GCA TA-3', respectively.
Important proteins that can be modified by MDA adducts are as follows: (i) eElongation factor 2 (eEF2) catalyzes the movement of the ribosome along the mRNA in protein synthesis.
