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 اولmutation screening in the mitochondrial d-loop region of tumoral and non-tumoral breast cancer in iranian patients
the mitochondrial dna (mtdna) mutations in mitochondrial coding and non coding regions seem to be important in carcinogenesis. the aim of this investigation was to evaluate coding region (mt-trnaphe and trnapro) and non-coding sequence, mitochondrial displacement loop (mtdna d-loop), in the cancerous and non-cancerous lesions of iranian patients with breast cancer (bc). genomic dna was extracte...
متن کاملMitochondrial DNA Mutations, Pathogenicity and Inheritance
Mitochondria contain their own DNA (mtDNA), which codes for 13 proteins (all subunits of the respiratory chain complexes), 22 tRNAs and 2 rRNAs. Several mtDNA point mutations as well as deletions have been shown to be causative in well-defined mitochondrial disorders. A mixture of mutated and wild type mtDNA (heteroplasmy) is found in most of these disorders. Inheritance of mtDNA is maternal, a...
متن کاملMutation in D-loop region of mitochondrial DNA in gastric cancer and its significance.
AIM To investigate the mutation in D-loop region of mitochondrial DNA in gastric cancer and its influence on the changes of reactive oxygen species (ROS) and cell cycle. METHODS The D-loop region was amplified by PCR and sequenced. Reactive oxygen species and cell cycle were detected by flow cytometry in 20 specimens from gastric cancer and adjacent normal tissues. According to the sequence r...
متن کاملGenetic Analysis of D-Loop Region of Mitochondrial DNA Sequence in Iranian Patients with Familial Adenomatous Polyposis (FAP): A Case-Control Study
Background and Objectives: Familial adenomatous polyposis (FAP) is an inherited disorder and a rare form of colorectal cancer. This disease appears equally in both sexes and its occurrence is more in the second or third decade of life. Mutations and alterations of the mitochondrial genome, especially the D-loop region, have been reported in various human tumors. But the exact role of these muta...
