Abstract Ethanol has a vast consumption around the world. Many researches confirmed some adverse effect of this component on human health. In addition, recent studies showed significant alteration in both cellular population, and protein profile of human foreskin fibroblast cell line (HFFF2) in the specific dosage of ethanol. Here, the role and interaction of some proteins (characterized by sig...

prostate-specific antigen (psa) was purified to homogeneity from human seminal plasma by ion-exchange chromatography on a cm-sephadex c-50 and by gel filtration on a sephacryl s-200 column. a single 33-kda protein band appeared in sds-page. high pressure liquid chromatography (hplc) of the purified protein produced a single peak, while isoelectric focusing demonstrated the presence of five diff...

human alpha 1-antitrypsin (aat) cdna was obtained from hepg2 cell lines. after pcr and construction of expression vector ppiczα-aat, human aat was expressed in the yeast pichia pastoris (p.pastoris) in a secretary manner and under the control of inducible alcohol oxidase 1 (aox1) promoter. the amount of aat protein in medium was measured as 60 mg/l 72 hr after induction with methanol. results i...

background: the potential of plants as a safe and eukaryotic systems, are considered for producing recombinant therapeutic human protein today; but the expression level of heterologous proteins is limited by the post-transcriptional gene silencing (ptgs) response in this new technology. the use of viral suppressors of gene silencing can prevent ptgs and improve transient expression level of for...

in this study tsga10 has been demonstrated as a testis-specific human gene that encodes a protein localized in sperm-tail and conserved in ciliary structure. further investigations showed tsga10 signalling and expression during embryogenesis, brain development and some malignancies including brain tumors. given the role of this protein in neuronal development and in certain tumors, it could pot...
