Psoriasis is a chronic, inflammatory skin disease characterized by well-defined, erythematous plaques with silvery scale secondary to aberrant keratinocyte proliferation. We have previously identified that structural membrane protein caveolin-1 (Cav1) involved in regulation of proliferation and differentiation, thus the aim this study was elucidate role Cav1 pathogenesis psoriasis vulgaris. uti...

Caveolin-1 (CAV1) is a scaffolding protein that plays a dual role in cancer. In advanced stages of this disease, CAV1 expression in tumor cells is associated with enhanced metastatic potential, while, at earlier stages, CAV1 functions as a tumor suppressor. We recently implicated CAV1 phosphorylation on tyrosine 14 (Y14) in CAV1-enhanced cell migration. However, the contribution of this modific...

BACKGROUND AND AIM Caveolin1 (CAV1) is involved in lipid homeostasis and endocytosis, but little is known about the significance of CAV1 in the pathogenesis and development of nonalcoholic fatty liver disease (NAFLD). This study aimed to determine the role of CAV1 in NAFLD. METHODS Expression of CAV1 in the in vitro and in vivo models of NAFLD was analyzed. The effects of CAV1 knockdown or ov...

Caveolin-1 (Cav1) plays a critical role in the invasion of pathogenic microbes into host cells, yet little is known about porcine Cav1. In this study, we provide the molecular characterization of Cav1 in pigs following stimulation with LPS/polyinosinic-polycytidylic acid as well as during infection with Haemophilus parasuis. The porcine Cav1 gene is 35 kb long and is located at SSC18q21; two is...

Caveolin-1 (CAV1) is an essential component of caveolae and is implicated in numerous physiological processes. Recent studies have identified heterozygous mutations in the CAV1 gene in patients with pulmonary arterial hypertension (PAH), but the mechanisms by which these mutations impact caveolae assembly and contribute to disease remain unclear. To address this question, we examined the conseq...

Caveolin-1 (CAV1) acts as a growth suppressor in various human malignancies, but its expression is elevated in many advanced cancers, suggesting the oncogenic switch of its role during tumor progression. To understand the molecular basis for the growth-promoting function of CAV1, we characterized its expression status, differential roles for tumor growth, and effect on glucose metabolism in col...

134 Background: Caveolin-1 (CAV1) is the structural component of caveolae, compartments within the plasma membrane that sequester signaling molecules, thus facilitating molecular "hot spots". The role of CAV1 in breast cancer is an active area of investigation. We sought to understand the clinical and pathological characteristics of CAV1 positive tumors (CAV 1+) through a retrospective analysis...

Here, we show that the Na/K-ATPase interacts with caveolin-1 (Cav1) and regulates Cav1 trafficking. Graded knockdown of Na/K-ATPase decreases the plasma membrane pool of Cav1, which results in a significant reduction in the number of caveolae on the cell surface. These effects are independent of the pumping function of Na/K-ATPase, and instead depend on interaction between Na/K-ATPase and Cav1 ...

Caveolin-1 (CAV1) and caveolin-2 (CAV2) are the major structural proteins of caveolae. We investigated the relationship between the clinicopathological factors of esophageal squamous cell carcinoma (ESCC) and the expression of CAV1 and CAV2. CAV1 and CAV2 expression were analyzed by quantitative reverse transcription-polymerase chain reaction (RT-PCR) in 15 esophageal cancer cell lines (TE1-15)...

Caveolin-1 (CAV1), an essential structural constituent of caveolae that plays an important role in cellular processes such as transport and signaling, has been implicated in the development of human cancers. However, it is unclear whether CAV1 is acting like an oncogene or tumor suppressor gene. We found that CAV1 expression was reduced or absent in 95% of small cell lung cancers (SCLCs; n = 21...
