Domain-wide regulation of gene expression in the human genome.
Transcription factor complexes bind to regulatory sequences of genes, providing a system of individual expression regulation. Targets of distinct transcription factors usually map throughout the genome, without clustering. Nevertheless, highly and weakly expressed genes do cluster in separate chromosomal domains with an average size of 80-90 genes. We therefore asked whether, besides transcript...
متن کاملthe study of aaag repeat polymorphism in promoter of errg gene and its association with the risk of breast cancer in isfahan region
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 اولBioinformatics Genome-Wide Characterization of the WRKY Gene Family in Sorghum bicolor
The WRKY gene family encodes a large group of transcription factors that regulate genes involved in plant response to biotic and abiotic stresses. Sorghum is a notable grain and forage crop in semi-arid regions because of its unusual tolerance against hot and dry environments. We identified a set of 85 WRKY genes in the S. bicolor genome and classified them into three groups (I–III). Among the ...
متن کاملInsulators: linking genome architecture to gene regulation
Insulator elements have long been associated with a proposed domain boundary function, ensuring appropriate associations between regulatory elements and transcription units through the physical organisation of the genome into looped domains. Recent experiments in Drosophila have, however, highlighted a more direct involvement of insulators in transcriptional regulation.
متن کاملTranscription factories: genome organization and gene regulation.
I will argue that transcription 'factories' are central organizers of the human genome during interphase, and that proximity to an appropriate factory determines the activity of a gene. The nucleolus is the prototypic factory; it is a place where many rRNA genes are efficiently co-transcribed by local concentrations of RNA polymerase I. Analogous clusters of RNA polymerase II in nucleoplasmic f...
