Protection against deadly pathogens requires the production of high-affinity antibodies by B cells, which are generated in germinal centers (GCs). Alteration of the GC developmental program is common in many B cell malignancies. Identification of regulators of the GC response is crucial to develop targeted therapies for GC B cell dysfunctions, including lymphomas. The histone H3 lysine 27 methy...
Intestinal metaplasia (IM) is a premalignant lesion associated with gastric cancer (GC) but is poorly described in terms of molecular changes. Here, we explored the role of TP53, a commonly mutated gene in GC, to determine if p53 protein expression and/or the presence of somatic mutations in TP53 can be used as a predictive marker for patients at risk of progressing to GC from IM. Immunohistoch...
BACKGROUND Gastric carcinoma (GC) is a common and lethal malignancy, and epithelial-mesenchymal transition (EMT) is believed to contribute to invasive and metastatic tumor growth. Aquaporin 3 (AQP3) is overexpressed in human GC tissues, while human epidermal growth factor (EGF) and hepatocyte growth factor, which can induce EMT, are able to up-regulate AQP3 expression, subsequently promoting GC...
Rift Valley fever is a mosquito-transmitted, zoonotic disease that infects humans and ruminants. Dendritic cell specific intercellular adhesion molecule 3 (ICAM-3) grabbing non-integrin (DC-SIGN) acts as a receptor for members of the phlebovirus genus. The Rift Valley fever virus (RVFV) glycoproteins (Gn/Gc) encode five putative N-glycan sequons (asparagine (N)-any amino acid (X)-serine (S)/thr...
With so many diverse functions such as transporter of vitamin D metabolites and fatty acids, actin scavenger and macrophage activating factor, Gc must have been one of the most conserved proteins in animal kingdom. Our objective was to investigate the evolution of Gc by analyzing its differences at protein level. Using BLAST (Basic Local Alignment Search Tool) searches, Gc amino acid sequences ...
روش میکرواستخراج فاز جامد به عنوان یک روش تجاری برای آماده سازی نمونه ها توسط بلاردی و پائولزین در سال 1989 ارائه شد. استفاده از نانولوله های کربنی برای تهیه پوشش در روش میکرواستخراج فاز جامد و با توجه به رفتار مکانیکی، الکتریکی و شیمیائی آن ناتوانیهای فیبرهای تجاری را به میزان زیادی برطرف کرده است. روشهای متفاوتی برای تهیه پوشش نانولوله های کربنی جهت استفاده در میکرواستخراج فاز جامد وجود دارد ...
BACKGROUND Guanylate Cyclase C (GC-C; Gucy2c) is a transmembrane receptor expressed in intestinal epithelial cells. Activation of GC-C by its secreted ligand guanylin stimulates intestinal fluid secretion. Familial mutations in GC-C cause chronic diarrheal disease or constipation and are associated with intestinal inflammation and infection. Here, we investigated the impact of GC-C activity on ...
