background: erythropoietin (epo) is a glycoprotein hormone function to regulate the production of red blood cells. deficiency of epo is known to cause anemia in chronically infected renal patients and they require regular blood transfusion. availability of recombinant epo has eliminated the need for blood transfusion and now it is extensively used for the treatment of anemia. glycosylation of e...

the anti-cancer activity of metal ions in the lanthanide group is being considered recently. it has been reported that cerium salts might stimulate the metabolism and therefore, produce anti-cancer effects. however, little is known about the effects of protein-cerium complex in controlling cancer cell growth. the aim of the present study was to elucidate the possible pathways for the cytotoxic ...

Selenium has cancer-preventive activity that is mediated, in part, through selenoproteins. The role of the 15-kDa selenoprotein (Sep15) in colon cancer was assessed by preparing and using mouse colon CT26 cells stably transfected with short hairpin RNA constructs targeting Sep15. Metabolic (75)Se labeling and Northern and Western blot analyses revealed that >90% of Sep15 was downregulated. Grow...

Previous work from our laboratory showed that hydrocortisone (HC) combined with IL-15 induces expansion of activated human NK cells. We set up an experimental tumor model to evaluate the use of adoptively transferred, HC plus IL-15 (HC/IL-15)-activated and -expanded murine NK cells in the treatment of syngeneic mice carrying established lung metastases of the CT26 transplantable tumor. We also ...

Tumors survive and progress by evading killing mechanisms of the immune system, and by generating a tumor microenvironment (TME) that reprograms macrophages in situ to produce factors that support tumor growth, angiogenesis, and metastasis. We have previously shown that by blocking the translation of the enzyme inducible nitric oxide synthase (iNOS), miR-146a-5p inhibits nitric oxide (NO) produ...

abstract background and aims: to identify and isolation of viruses a susceptible cell is need which can be primary or line. the use of primary cells is laborious, time consuming and expensive, while the use of cell lines is much easier and faster. irkhbk cell line was originated from primary cells of bovine kidney by continuous passage. the aim of this study was to introduce the irkhbk cell lin...

objective: the study of physiological changes in recombinant cell lines provides useful information to improve production performance. in this study, we investigate the effects of an anti-cd33 chimeric igg4 expression on sp2.0 cell growth. methods: variable region genes of light and heavy chains of monoclonal antibody produced by m195 were cloned in pfuse-clig-hk and pfuse-chig-hg4 expression ...

background: both azadirachtin and rotenone, two botanical pesticides have shown inhibit the growth of cultured insect cells. the inhibitory effect of rotenone on cell growth is through disruption of electron transport chain, but exact mechanism of effect of azadirachtin on growth of cell is unknown. this study was carried out to compare the effect of these phytochemical on oxygen consumption by...

Colon cancer is characterized by its fast progression and poor prognosis, and novel agents of treating colon cancer are urgently needed. WZ35, a synthetic curcumin derivative, has been reported to exhibit promising antitumor activity. Here, we investigated the in vitro and in vivo activities of WZ35 and explored the underlying mechanisms in colon cancer cell lines. WZ35 treatment significantly ...
