Thyroid-specific transcription factors control Hex promoter activity.
The homeobox-containing gene Hex is expressed in several cell types, including thyroid follicular cells, in which it regulates the transcription of tissue- specific genes. In this study the regulation of Hex promoter activity was investigated. Using co- transfection experiments, we demonstrated that the transcriptional activity of the Hex gene promoter in rat thyroid FRTL-5 cells is approximate...
متن کاملCCR5 promoter alleles and specific DNA binding factors.
At least 12 single nucleotide polymorphisms (SNPs) within the 59 upstream regulatory region of the human CCR5 chemokine and HIV-1 receptor gene have been described (1–4). Our recent report (1) and others (2) have shown that a common 10-SNP allele haplotype, CCR5P1, with demonstrated promoter activity (5) confers relatively rapid progression to various AIDS end points in a genetic epidemiologic ...
متن کاملModulation of DNA binding by gene-specific transcription factors.
The transcription of many genes, particularly in prokaryotes, is controlled by transcription factors whose activity can be modulated by controlling their DNA binding affinity. Understanding the molecular mechanisms by which DNA binding affinity is regulated is important, but because forming definitive conclusions usually requires detailed structural information in combination with data from ext...
متن کاملSpecific DNA-binding by apicomplexan AP2 transcription factors.
Malaria remains one of the most prevalent infectious diseases worldwide, affecting more than half a billion people annually. Despite many years of research, the mechanisms underlying transcriptional regulation in the malaria-causing Plasmodium spp., and in Apicomplexan parasites generally, remain poorly understood. In Plasmodium, few regulatory elements sufficient to drive gene expression have ...

چکیده: در میان انواع متفاوتی از مبدل های آنالوگ به دیجیتال که تا کنون معرفی شده اند، مبدل های آنالوگ به دیجیتال تقاریب متوالی(sar ) به علت سادگی ساختار و همچنین توان مصرفی کم، همواره یکی از پرکاربرد ترین مبدل های آنالوگ به دیحیتال در کاربرد های بایومدیکال بوده اند. به همین دلیل تاکنون روش های متعددی برای کاهش هرچه بیشتر توان مصرفی در این مبدل ها ارائه شده است که در اکثر آنها توجهی به مشخصات سی...
