سابقه و هدف: انتروباکترها متعلق به خانواده انتروباکتریاسه‌اند که دارای مشخصات متنوعی از نظر فنوتیپ و ژنو‌تیپ هستند. در مورد انتروباکترکلوآکه، شش گونه مشابه از نظر فنوتیپیک و ژنوتیپیک در یک کمپلکس به عنوان کمپلکس انتروباکترکلوآکه گنجانده شده‌اند و جدایه‌های وابسته آن جزء بیش‌ترین جدایه‌های عامل ایجاد عفونت‌های فرصت‌طلب سخت در بیمارستان می‌باشند. بر اساس توالی ژن hsp60 در این کمپلکس 13 خوش...
The mitochondrial chaperonin Hsp60 is a ubiquitous molecule with multiple roles, constitutively expressed and inducible by oxidative stress. In the brain, Hsp60 is widely distributed and has been implicated in neurological disorders, including epilepsy. A role for mitochondria and oxidative stress has been proposed in epileptogenesis of temporal lobe epilepsy (TLE). Here, we investigated the in...
Cell survival and proliferation are central to carcinogenesis, involving various mechanisms among which those that impede apoptosis are important. In this, the role of the molecular chaperone Hsp60 is unclear since it has been reported that it can be both, pro- or anti-apoptotic. A solution to this riddle is crucial to the development of anti-cancer therapies targeting Hsp60. We addressed this ...
Heat shock protein 60s (hsp60) are remarkably immunogenic, and both T-cell and antibody responses to hsp60 have been reported in various inflammatory conditions. To clarify the role of hsp60 in T-cell responses in periodontitis, we examined the proliferative response of peripheral blood mononuclear cells (PBMC), as well as the cytokine profile and T-cell clonality, for periodontitis patients an...
Molecular mimicry between viral antigens and host proteins was often suggested to be involved in induction of autoimmune diseases. In type 1 diabetes where pancreatic 13 cells are destroyed by autoimmune phenomena, a linear sequence homology between a major autoantigen, glutamate decarboxylase (GAD), and the 2C protein of coxsackie B4 was identified. In addition, a sequence homology between GAD...
In the present study, we demonstrate that HSP60 is unequivocally downregulated in clear cell renal cell carcinoma (ccRCC) tissues compared to pericarcinous tissues. Overexpression of HSP60 in ccRCC cancer cells suppresses cell growth. HSP60 knockdown increases cell growth and proliferation in both cell culture and nude mice xenografts, and drives cells to undergo epithelial to mesenchymal trans...
The mechanism of chaperonin-assisted protein folding has been mostly analyzed in vitro using non-homologous substrate proteins. In order to understand the relative importance of hsp60 and hsp10 in the living cell, homologous substrate proteins need to be identified and analyzed. We have devised a novel screen to test the folding of a large variety of homologous substrates in the mitochondrial m...
OBJECTIVE To assess associations of Chlamydia trachomatis and Mycoplasma genitalium antibodies with epithelial ovarian tumors. METHODS Plasma samples from 291 women, undergoing surgery due to suspected ovarian pathology, were analyzed with respect to C. trachomatis IgG and IgA, chlamydial Heat Shock Protein 60-1 (cHSP60-1) IgG and M. genitalium IgG antibodies. Women with borderline tumors (n=...
BACKGROUND It is increasingly clear that some heat shock proteins (Hsps) play a role in inflammation. Here, we report results showing participation of Hsp60 in the pathogenesis of chronic obstructive pulmonary diseases (COPD), as indicated by data from both in vivo and in vitro analyses. METHODS AND RESULTS Bronchial biopsies from patients with stable COPD, smoker controls with normal lung fu...
Porphyromonas gingivalis is associated with human periodontal disease. We cloned and sequenced the gene for heat shock protein 60 (GroEL, HSP60) from P. gingivalis FDC381. The identified clone carried a 2.6 kb DNA fragment which contained two open reading frames (ORFs) encoding a 9.6- and a 58.4-kDa protein. The translated amino acid sequence of these ORFs showed a high degree of homology with ...
