Introduction: t(14;18)-neg FL cases show similar copy number alterations and mutations as carried by t(14;18)-pos FL, but with different frequencies. STAT6 are significantly more frequent in than correlate CD23 expression. The consequences of have not been investigated, the impact pathway activation on tumor microenvironment, which plays a central role largely unknown. (i.e., IL4R), demonstrate...
SOCS1 is an SH2-containing protein that is primarily expressed in thymocytes in a cytokine- and T cell receptor-independent manner. SOCS1 deletion causes perinatal lethality with death by 2-3 weeks. During this period thymic changes include a loss of cellularity and a switch from predominantly CD4+ CD8+ to single positive cells. Peripheral T cells express activation antigens and proliferate to ...
Treatment with tyrosine kinase inhibitors is the standard of care for Philadelphia chromosome positive leukemias. However the eradication of leukemia initiating cells remains a challenge. Circumstantial evidence suggests that the cytokine microenvironment may play a role in BCR-ABL mediated leukemogenesis and in imatinib resistance. Gene expression analyses of BCR-ABL positive ALL long-term cul...
Primary biliary cholangitis (PBC) is an immune-mediated cholestatic disease. Vitamin D receptor (VDR)-dependent signaling constrains an inflammatory response by targeting the miRNA155-SOCS1 (suppressor of cytokine signaling 1) axis. The VDR-miRNA155-SOCS1 pathway was investigated in the context of the autoimmune response associated with PBC. Human liver tissues from non-cirrhotic PBC (n = 22), ...
Regulatory T cells (Tregs) play an indispensable role in the prevention of autoimmune disease, as interferon gamma (IFNγ) mediated, lethal auto-immunity occurs (in both mice and humans) in their absence. In addition, Tregs have been implicated in preventing the onset of autoimmune and auto-inflammatory conditions associated with aberrant IFNγ signaling such as type 1 diabetes, lupus, and lipopo...
The NF-κB pathway is central to the regulation of inflammation. Here, we demonstrate that the low-output nitric oxide (NO) synthase 1 (NOS1 or nNOS) plays a critical role in the inflammatory response by promoting the activity of NF-κB. Specifically, NOS1-derived NO production in macrophages leads to proteolysis of suppressor of cytokine signaling 1 (SOCS1), alleviating its repression of NF-κB t...
background recent studies revealed that tumor-associated macrophages (tams) play a decisive role in the regulation of tumor progression by manipulating tumor oncogenesis, angiogenesis and immune functions within tumor microenvironments. signal transducer and activator of transcription 3 (stat3), which is a point of convergence for numerous oncogenic signalling pathways, is constitutively activa...
مقدمه: بدخیمی معده دومین علت شایع مرگ ناشی از بدخیمی است و سالانه یک میلیون ابتلای جدید به آن گزارش می‌شود. فعالیت نابجای STAT3 به عنوان انکوژن، نقشی حیاتی در تومورزایی گستره دامنگیری از سرطان‌ها مانند بدخیمی معده ایفا می‌کند. STAT3، عامل رونویسی کلیدی برای بسیاری از سیتوکین‌ها و عوامل رشد است که نقش بنیادی در ترازمندی بسیاری از فرایندهای درون سلولی همچون تکثیر سلولی، مرگ سلولی، رگ‌زایی، متاستا...
This paper reports findings from an AHRC-funded project into the use of more than one language in research projects. Using 35 seminar presentations and 25 researcher profiles, we investigated how researchers from differing disciplines became aware of the possibilities, complexities, and emerging practices of researching where more than one language is used: for example, in initial research desi...
Variations of heavy metals concentrations (Pb, Zn, Ni and Cd) in suspended matter as well as the physical properties (temperature, salinity, dissolved oxygen and pH) at five coastal sites and one reference station (offshore) were measured on seasonal base of the year 2005. Seasonal variations of seawater temperature, salinity, pH and dissolved oxygen were significant different, meanwhile; spati...
