Rakicidin A effectively induces apoptosis in hypoxia adapted Bcr-Abl positive leukemic cells.
Treatment with Abl tyrosine kinase inhibitors (TKI) drastically improves the prognosis of chronic myelogenous leukemia (CML) patients. However, quiescent CML cells are insensitive to TKI and can lead to relapse of the disease. Thus, research is needed to elucidate the properties of these quiescent CML cells, including their microenvironment, in order to effectively target them. Hypoxia is known...
متن کاملفراوانی آنتی‌بادی ضد Cytotoxin associated Gene A در استان گلستان
زمینه و هدف : سویه‌های باکتری هلیکوباکترپیلوری که دارای پروتئین Cag A (Cytotoxin associated Gene A) می‌باشند؛ استعداد بیشتری برای ایجاد بیماری دارند. این پروتئین بیماری‌زایی باکتری را با افزایش تولید سیتوتوکسین در سلول میزبان تسریع می‌نماید. این مطالعه به منظور تعیین فراوانی آنتی‌بادی ضد CagA در افراد آلوده به هلیکوباکترپیلوری در استان گلستان انجام شد. روش بررسی : این مطالعه توصیفی روی 676 ...
متن کاملGas chromatographic identification of Clostridium difficile and detection of cytotoxin from a modified selective medium.
A modification of an existing selective medium for Clostridium difficile is described. Inclusion in the medium of DL nor-leucine and p-hydroxyphenylacetic acid enables identification of C difficile to be made directly from primary isolation plates by gas chromatographic detection of caproic acid and p-cresol. Plugs of agar withdrawn from the selective medium also allow the detection of cytotoxi...

Haemophilus ducreyi, a cytotoxin-producing bacterium.
An extra- and an intracellular product from the bacterium Haemophilus ducreyi were shown to have a cytotoxic effect on cell lines of epithelial origin, e.g., HEp-2 and HeLa cells. The cytotoxic effect appeared on cells within 24 h and resulted in cell death and morphologically changed cells. The cytotoxic activity was heat and pronase sensitive. The activity could be removed by incubation with ...
