کاوئولین1 (cav1) ژنی از خانواده پروتئین کاوئول است که سطح سیتوپلاسمی ساختار های کاوئول واقع در غشا سلولی را می پوشاند. در ناحیه بالادست ژن این پروتئین، ناحیه ای غنی از پورین وجود دارد که به شدت پلی مورف بوده و دارای موتیف های gaaa و ggaa می باشد که محل اتصال گروهی از فاکتورهای رونویسی نظیر ets، irf و stat4 است. . بیان افزایش یافته ژن cav1 در مدل های حیوانی بیماری ms و نیز مغز بیماران مبتلا به آ...
Caveolin-1 (CAV1) is an essential structural constituent of caveolae, specialized lipid raft microdomains on the cell membrane involved in endocytosis and signal transduction, which are inexplicably deregulated and are associated with aggressiveness in numerous cancers. Here we identify CAV1 as a direct transcriptional target of oxygen-labile hypoxia-inducible factor 1 and 2 that accentuates th...
بیماری multiple sclerosis (ms) به عنوان یکی از بیماری های خودایمن و تخریب کننده ی میلین در ماده ی سفید سیستم عصبی مرکزی می باشد. این بیماری به طور عمده در افراد جوان شیوع داشته و منجر به ناتوانی های بسیاری در آنان می گردد. با توجه به بررسی های انجام گرفته، نقش ژن(cav1) caveolin1 در مسیرهای ملکولی سنتز میلین در نمونه های حیوانی مشابه ms به اثبات رسیده است. همچنین این پروتئین در حفظ انسسجام سد خ...
Respiratory syncytial virus (RSV) is a significant cause of severe respiratory illness worldwide, particularly in infants, young children, and the elderly. Although no licensed vaccine is currently available, an engineered version of the metastable RSV fusion (F) surface glycoprotein-stabilized in the pre-fusion (pre-F) conformation by "DS-Cav1" mutations-elicits high titer RSV-neutralizing res...
Activity-dependent CREB phosphorylation and gene expression are critical for long-term neuronal plasticity. Local signaling at CaV1 channels triggers these events, but how information is relayed onward to the nucleus remains unclear. Here, we report a mechanism that mediates long-distance communication within cells: a shuttle that transports Ca(2+)/calmodulin from the surface membrane to the nu...
PURPOSE The relationship between caveolin-1 (CAV1) G14713A polymorphism and cancer susceptibility remains inconclusive. The current meta-analysis was performed on the basis of a systematic search in electronic databases for a more precise estimation of the associations. METHODS Odds ratio (OR) with 95% confidence interval (CI) was used to estimate the pooled effect. RESULTS A total of 12 st...
The inflammatory milieu in the respiratory tract in cystic fibrosis (CF) has been linked to the defective expression of the cystic transmembrane regulator (CFTR) in epithelial cells. Alveolar macrophages (AM), important contibutors to inflammatory responses in the lung, also express CFTR. The present study analyzes the phenotype of human AM with silenced CFTR. Expression of CFTR mRNA and the im...
The 7q31 locus contains several genes affected in cancer progression. Although evidences exist regarding its impact on tumorigenesis, the role of genetic alterations and the expressions of locus-related genes are still controversial. Our study aimed to define the 7q31 copy number alterations in primary melanomas, primary-metastatic tumor pairs and cell lines. Data were correlated with clinical-...
This study aimed to explore the genetic association of polymorphisms in caveolin-1 gene (CAV1) with hepatitis B virus-related hepatocellular carcinoma (HBV-related HCC) susceptibility in a Chinese Han population.The genotyping of polymorphism was conducted using polymerase chain reaction-restriction fragment length polymorphism method. Whether the genotype distribution of polymorphisms in the h...
We have utilized small interfering RNA (siRNA)-mediated depletion of the beta-COP subunit of COP-I to explore COP-I function in organellar compartmentalization and protein traffic. Reduction in beta-COP levels causes the colocalization of markers for the endoplasmic reticulum (ER)-Golgi intermediate compartment (ERGIC), Golgi, trans-Golgi network (TGN), and recycling endosomes in large, globula...
