the 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 اولTemperature-sensitive yeast mutants defective in mitochondrial inheritance
The distribution of mitochondria to daughter cells is an essential feature of mitotic cell growth, yet the molecular mechanisms facilitating this mitochondrial inheritance are unknown. We have isolated mutants of Saccharomyces cerevisiae that are temperature-sensitive for the transfer of mitochondria into a growing bud. Two of these mutants contain single, recessive, nuclear mutations, mdm1 and...
متن کاملPromotor mutants of the yeast his3 gene.
The DNA sequences, transcription patterns and genetic behaviours of the wild-type his3 gene from Saccharomyces cereviaiar (yeast) and of seven mutations that delete sequences flanking the 5’.end of the messenger RNA coding region are described. The deleted derivatives behave as promoter mutants because they are cis-dominant’ and fail to make detectable levels of his3 mRNA. The results indicate ...
متن کاملTransformation and expression of Penicillium funicolusum glucose oxidase gene in yeast
Glucose oxidase is an important enzyme hydrolyzing for its hydrolyzing activity on glucos. It possesses and has a wide board of applications in different industries such as bakery, pharmaceutical, plant pathology and biosensors. In this study, yeast (Saccharomyces cerevisiae) was transformed successfully by the glucose oxidase gene (gox) obtained from Penicillium funicolusum. The secreted gluco...
متن کاملA yeast H2A-H2B promoter can be regulated by changes in histone gene copy number.
The two divergently transcribed H2A-H2B gene pairs in yeast are differentially regulated as a function of the copy number of histone genes. Transcription of an HTA2-lacZ reporter gene is independent of histone gene copy number. Transcription of an HTA1-lacZ gene can be repressed or derepressed, depending on the number of HTA plus HTB genes in cells. Regulation by histone gene dosage is dependen...
