Characterization of the arginine decarboxylase gene (ORF HP0422, speA) involved in acid tolerance in Helicobacter pylori.
BACKGROUND Helicobacter pylori is a motile microaerophilic bacterium that colonizes the human stomach. H. pylori infection triggers gastric diseases, such as gastritis, peptic ulcer and gastric cancer. Stomach represents a barrier for microorganism colonization, particularly because of its high hydrochloric acid concentration. The main mechanism developed by H. pylori to maintain intracellular ...
متن کاملMarkerless multiple-gene-deletion system for Streptococcus mutans.
Inactivation or selective modification is essential to elucidate the putative function of a gene. The present study describes an improved Cre-loxP-based method for markerless multiple gene deletion in Streptococcus mutans, the principal etiological agent of dental caries. This modified method uses two mutant loxP sites, which after recombination creates a double-mutant loxP site that is poorly ...
متن کاملGENERATION OF A GENE CONSTRUCT TO SIPA GENE DELETION OF SALMONELLA TYPHIMURIUM
Background & Aims: Salmonella Typhimurium is a negative-gram, non-spore, free capsule, moving bacteria with Trish Perry flagella. Salmonella is the most common cause of food poisoning. The ability to enter and survive in host cells is the condition for pathogenic Salmonella species. Proteins of invasive Salmonella are transferred to the host cells by bacteria. This study was performed for gener...
متن کاملGene deletion patterns in non-aflatoxigenic isolates of Aspergillus flavus
Fifteen non-aflatoxigenic strains of Aspergillus flavus, represent a wide range of geographic regions of Iran (six provinces include Fars, Ardebil, Guilan, Golestan, Kerman and Semnan) and vegetative compatibility groups (VCGs), were collected from corn (Zea mays L.), peanut (Arachis hypogaea L.) and pistachio (Pistachia vera L.) soils and kernels, were screened for the presence of aflatoxin bi...

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...
