Previous work has shown that multiple HeLa nuclei injected into Xenopus oocytes remain transcriptionally active for many days and that the expression of HeLa genes in oocytes can be detected by 2-D gel electrophoresis. We show here that of 25 proteins which have the electrophoretic properties of HeLa gene products, only 3 are expressed in injected oocytes. To test that these proteins are produc...

به طور کلی، هر سلول طبیعی بدن انسان، که مشتمل بر قسمت‌های مختلفی همچون هسته، غشاء سلولی و نانوالیاف پروتئینی می‌باشد، دارای سختی استحکام مکانیکی مشخصی است. هرگونه تغییر محسوس در این استحکام، نشان از یک بیماری دارد. یکی راه‌های تشخیص بیماری‌های مختلف سرطان های سنجش میزان تغییرات رخ داده خواص آن‌ها می‌باشد. مقالۀ حاضر، مشخصات شامل مدول الاستیسیته نیروی چسبندگی Ago-1522 سلول‌های پوست محسوب می‌شود،...

HeLa cells grown in tissue culture have certain components in common with normal human tis sues. For example, Miller and Hsu (6) have shown that antiserum prepared against HeLa cells in rabbits is cytotoxic for fibroblasts and epithelial cells derived from adult and newborn skin and also from tonsils, as well as for HeLa. Moreover, the anti-HeLa serum gave a precipitate with an extract of human...

Objective: Cancer is a major health problem worldwide and current therapies for cancer are often limited by short-term efficacy due to drug resistance. There has been much interest in the use of naturally occurring compounds with chemo-preventive and chemotherapeutic properties in the treatment of cancers. Rose is one of the most important groups of ornamental plants which their fruits and flo...

HeLa Cells have been found to produce a placental form of alkaline phosphatase (1, 8, 17) which is very similar to the Regan isoenzyme, a carcinoplacental antigen found in cancer patients (7-9) . In order to investigate the nature of gene expression of carcinoplacental proteins, HeLa cells were cloned, and a subline (HeLa TCRC-1), monophenotypic for the Regan isoenzyme was selected . The proper...
