Despite their essential role in protection, T cells can be dangerous if unregulated. Dysfunctional T cell activity has been implicated in numerous diseases, including the failure of organ transplants, allergic reactions, multiple sclerosis, and coronary artery disease. Signal transduction pathways activated by the T cell receptor (TCR) are good targets for the development of therapies. However,...
Ovarian cancer is mainly confined in peritoneal cavity and its metastasis is often associated with the formation of malignant ascites. As lysophosphatidic acid (LPA) is present at high levels in ascites of ovarian cancer patients and potently stimulates cell migration, we reason that LPA-stimulated cell migration may play an important role in ovarian cancer metastasis. Here, we show that only o...
Cortical microtubule arrays are critical in determining the growth axis of diffusely growing plant cells, and various environmental and physiological factors are known to affect the array organization. Microtubule organization is partly disrupted in the spiral1 mutant of Arabidopsis thaliana, which displays a right-handed helical growth phenotype in rapidly elongating epidermal cells. We show h...
Eutrema salsugineum and Schrenkiella parvula are salt-tolerant relatives of the salt-sensitive species Arabidopsis thaliana. An important component of salt tolerance is the regulation of Na(+) ion homeostasis, which occurs in part through proteins encoded by the Cation/Proton Antiporter-1 (CPA1) gene family. We used a combination of evolutionary and functional analyses to examine the role of CP...
The genome of Thellungiella parvula, a halophytic relative of Arabidopsis (Arabidopsis thaliana), is being assembled using Roche-454 sequencing. Analyses of a 10-Mb scaffold revealed synteny with Arabidopsis, with recombination and inversion and an uneven distribution of repeat sequences. T. parvula genome structure and DNA sequences were compared with orthologous regions from Arabidopsis and p...
African-American (AA) men experience an increased risk of developing prostate cancers as well as increased mortality following treatment as compared to European-American (EA) men. The aim of our study was to identify biological factors with the potential to predispose AA men to prostate tumor progression and metastasis. To identify cancer-specific gene expression patterns in AA men, we establis...
سابقه و هدف: سیستم های sos مهم ترین نقش را در تحمل شوری گیاه دارد. این سیستم در آرابیدوپسیس تالیانا به عنوان یک سیستم پیام رسانی سلول در مسیرهای تحمل به تنش شوری عمل می کند. مواد و روش ها: در این تحقیق با بررسی توالی ژن sos1 در آرابیدوبسیس از پایگاه tair، ebi، ncbi، plantcare وexpasy و هم چنین جهت بررسی روابط این ژن در سیزده گونه گیاهی مختلف، میزان همولوژی آن ها از لحاظ میزان تشابه با نرم افزار...
For plants growing in highly saline environments, accumulation of sodium in the cell cytoplasm leads to disruption of metabolic processes and reduced growth. Maintaining low levels of cytoplasmic sodium requires the coordinate regulation of transport proteins on numerous cellular membranes. Our previous studies have linked components of the Salt-Overly-Sensitive pathway (SOS1-3) to salt toleran...
