Specific factor conferring nuclease hypersensitivity at the 5' end of the chicken adult beta-globin gene.
Chromatin in the 5' flanking region of the transcriptionally active chicken adult beta(beta A) globin gene is hypersensitive to nuclease digestion. When plasmids carrying this gene are combined with histones in the presence of extracts from 9-day-old chicken erythrocyte nuclei, the resultant complex displays hypersensitive behavior in the same region. No such behavior is observed with extracts ...
متن کاملFunctional properties of the beta-globin locus control region in K562 erythroleukemia cells.
In this report, we compare the function of the human beta-globin locus control region (LCR) in three K562 erythroleukemia cell assays, including (1) a transient transfection assay for "classical" enhancer activity, (2) a colony assay that detects "productive integration events," and (3) an assay that detects the ability of LCR fragments to confer hemin inducibility on linked, stably integrated ...

چکیده: سرطان پستان دومین عامل مرگ مرتبط با سرطان در خانم ها است. از آنجا که سرطان پستان یک تومور وابسته به هورمون است، می تواند توسط وضعیت هورمون های استروئیدی شامل استروژن و پروژسترون تنظیم شود. استروژن نقش مهمی در توسعه و پیشرفت سرطان پستان ایفا می کند و تاثیر خود را روی بیان ژن های هدف از طریق گیرنده های استروژن اعمال می کند. اما گروه دیگری از گیرنده های هسته ای به نام گیرنده های مرتبط به ا...
15 صفحه اولP-122: The Effect of Beta Globin Intron on Human LH Hormone Expression in CHO Cells
Background Luteinizing hormone (LH) is a heterodimeric glycoprotein composed of alpha and beta subunits.This hormone is secreted from the pituitary gland. LH, in women triggers Menstrual cycle and ovulation. In men, LH stimulates production of testosterone, which plays a specialized role in sperm production. Up to day, LH hormone have produced in different ways such as codon optimization and al...
متن کاملP-127: The Effect of Beta Globin Intron on Human FSH Hormone Expression in CHO Cells
Background Follicle stimulating hormone (FSH)- a hetrodimeric glycoprotein- is secreted by pituitary gland. This hormone stimulates growth and maturation of the follicles in females and sperms in male. Up to now, glycoprotein hormones such as FSH have produced in different cell lines. Among of the mammalian expression systems, the Chinese hamster ovary cells (CHO) have taken into consideration ...
