Direct detection of mutations in the breast and ovarian cancer susceptibility gene BRCA1 by PCR-mediated site-directed mutagenesis.

The tumor suppressor genes BRCA1 and BRCA2, which confer increased susceptibility to breast and (or) ovarian cancer, were recently identified. Mutation analysis of BRCA1 has demonstrated significant allelic heterogeneity; however, some distinct mutations have been detected in unrelated individuals. The most notable is the 185delAG mutation, which occurs at an estimated frequency of approximatel...

Site-directed mutagenesis using PCR-mediated introduction of silent mutations.

The alteration of a specific sequence of DNA using site-directed mutagenesis (SDM) provides an effective tool to probe the structure and function of gene products. With the advent of polymerase chain reaction (PCR), several new techniques were developed that facilitate SDM. An oligonucleotide containing mismatches at the desired site of mutation is used to generate a population of mutant fragme...

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...

Genetic diagnosis of cancer: diagnosis of mutations in BRCA1 and BRCA2 in breast cancer

During the last two decays the tremendous success in molecular biology and genetics which has surprised the entire world. So that today the sequencing of whole genome has been possible for each human individual to estimate its being affected with cardiovascular and cancer diseases. However, these achievements have some important limitations and deep ethical issues which might be ignored. Geneti...

BRCA1 gene mutations in sporadic ovarian carcinomas: detection by PCR and reverse allele-specific oligonucleotide hybridization.

BACKGROUND Although germline mutations in BRCA1 play a central role in familial breast and ovarian cancers, to date, no somatic mutations in BRCA1 have been reported in sporadic breast cancer, and only five somatic mutations have been identified in the sporadic ovarian carcinomas. Because loss of heterozygosity appears frequently at the BRCA1 locus in nonfamilial breast and ovarian carcinomas, ...
