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...
انتقال dna به داخل یاخته های پستانداران بوسیله دندروزومها، یکی از جدیدترین روشهای انتقال dna به داخل یاخته محسوب می شود که مزایای زیادی نسبت به روشهای قدیمی تر مانند فسفات کلسیم، دکستران، لیپوزومها، دندریمرها و الکتروپوریشن دارند. دندروزومها، ارزان، خنثی و غیر سمی هستند. یاخته های اندوتلیال رگ بندناف انسان، نقش مهمی در خونسازی، عملکرد رگها و ایمنی زایی دارند با توجه به این اعمال فیزیولو...
objective(s): regarding the presence of many active biological constituents in avicennia marina, the present investigation was carried out to study cytotoxic activity of crude methanol leave extract and column chromatographic fractions of a. marina against mda-mb 231 cell line (human breast cancer cell) and hek (human embryonic kidney cell) line . materials and methods: the anticancer activit...

the present study was carried out to investigate cytotoxic activity of flower, leaf, stem and root extracts of five artemisia species against breast cancer cell line (mcf7) and human embryonic kidney normal cell line (hek293). the studied artemisia species were a. absinthium , a. vulgaris , a. incana , a. fragrans and a. spicigera . the cytotoxic activity was measured by mtt assay at different ...
background: creation of artificial gametes may provide a universal solution for these patients of lacking gametes. stem cell technology may provide a way to obtain fully functional gametes. retinoic acid (ra) can initiate meiosis. several studies have demonstrated that ra can promote sperm cells differentiation from mouse embryonic stem cells (mescs) and other cells from human embryonic stem ce...
background: heme oxygenase-1 (ho-1) is a cytoprotective and antiapoptotic enzyme, which has been involved in maintaining cellular homeostasis, and plays an important protective role by modulating oxidative injury. up-regulation of (ho-1) has contributed to tumorogenicity of some cancers. in this study we investigated the expression pattern of the ho-1, in five different human-derived cancer cel...
background: recent researches have demonstrated that human t-cell immunoglobulin mucin 1 (tim-1) glycoprotein plays important roles in regulation of autoimmune and allergic diseases, as well as in tumor immunity and response to viral infections. therefore,targeting tim-1 could be a potential therapeutic approach against such diseases.objectives: in this study, we aimed to express tim-1 protein ...
introduction: type i diabetes mellitus is caused by autoimmune destruction of the insulin-producing β-cells. a new potential method for curing the disease is transplantation of differentiated insulin- secreting cells from human embryonic stem cells. methods: human embryonic stem cell lines (royan h1) were used to produce embryoid bodies. differentiation carried out by growth factor-mediated sel...
