PROTEINS are linear polypeptides that are normally synthesized on RIBOSOMES.Caveolin 1: A tyrosine phosphoprotein that plays an essential role in CAVEOLAE formation. It binds CHOLESTEROL and is involved in LIPIDS transport, membrane traffic, and SIGNAL TRANSDUCTION.Caveolins: The main structural proteins of CAVEOLAE. Several distinct genes for caveolins have been identified.Caveolin 2: Caveolin 2 is a binding partner of CAVEOLIN 1. It undergoes tyrosine phosphorylation by C-SRC PROTEIN PP60 and plays a regulatory role in CAVEOLAE formation.Caveolae: Endocytic/exocytic CELL MEMBRANE STRUCTURES rich in glycosphingolipids, cholesterol, and lipid-anchored membrane proteins that function in ENDOCYTOSIS (potocytosis), transcytosis, and SIGNAL TRANSDUCTION. Caveolae assume various shapes from open pits to closed vesicles. Caveolar coats are composed of CAVEOLINS.Caveolin 3: A caveolin that is expressed exclusively in MUSCLE CELLS and is sufficient to form CAVEOLAE in SARCOLEMMA. Mutations in caveolin 3 are associated with multiple muscle diseases including DISTAL MYOPATHY and LIMB-GIRDLE MUSCULAR DYSTROPHY.Peptide Fragments: Partial proteins formed by partial hydrolysis of complete proteins or generated through PROTEIN ENGINEERING techniques.GTP-Binding Protein alpha Subunits: The GTPase-containing subunits of heterotrimeric GTP-binding proteins. When dissociated from the heterotrimeric complex these subunits interact with a variety of second messenger systems. Hydrolysis of GTP by the inherent GTPase activity of the subunit causes it to revert to its inactive (heterotrimeric) form. The GTP-Binding protein alpha subunits are grouped into families according to the type of action they have on second messenger systems.Cell Cycle: The complex series of phenomena, occurring between the end of one CELL DIVISION and the end of the next, by which cellular material is duplicated and then divided between two daughter cells. The cell cycle includes INTERPHASE, which includes G0 PHASE; G1 PHASE; S PHASE; and G2 PHASE, and CELL DIVISION PHASE.Cell Aging: The decrease in the cell's ability to proliferate with the passing of time. Each cell is programmed for a certain number of cell divisions and at the end of that time proliferation halts. The cell enters a quiescent state after which it experiences CELL DEATH via the process of APOPTOSIS.Endocytosis: Cellular uptake of extracellular materials within membrane-limited vacuoles or microvesicles. ENDOSOMES play a central role in endocytosis.Search Engine: Software used to locate data or information stored in machine-readable form locally or at a distance such as an INTERNET site.Cell Membrane: The lipid- and protein-containing, selectively permeable membrane that surrounds the cytoplasm in prokaryotic and eukaryotic cells.Fibroblasts: Connective tissue cells which secrete an extracellular matrix rich in collagen and other macromolecules.Electron Spin Resonance Spectroscopy: A technique applicable to the wide variety of substances which exhibit paramagnetism because of the magnetic moments of unpaired electrons. The spectra are useful for detection and identification, for determination of electron structure, for study of interactions between molecules, and for measurement of nuclear spins and moments. (From McGraw-Hill Encyclopedia of Science and Technology, 7th edition) Electron nuclear double resonance (ENDOR) spectroscopy is a variant of the technique which can give enhanced resolution. Electron spin resonance analysis can now be used in vivo, including imaging applications such as MAGNETIC RESONANCE IMAGING.Phosphoric Monoester Hydrolases: A group of hydrolases which catalyze the hydrolysis of monophosphoric esters with the production of one mole of orthophosphate. EC 3.1.3.Cell Movement: The movement of cells from one location to another. Distinguish from CYTOKINESIS which is the process of dividing the CYTOPLASM of a cell.Cell Polarity: Orientation of intracellular structures especially with respect to the apical and basolateral domains of the plasma membrane. Polarized cells must direct proteins from the Golgi apparatus to the appropriate domain since tight junctions prevent proteins from diffusing between the two domains.Vascular Endothelial Growth Factor A: The original member of the family of endothelial cell growth factors referred to as VASCULAR ENDOTHELIAL GROWTH FACTORS. Vascular endothelial growth factor-A was originally isolated from tumor cells and referred to as "tumor angiogenesis factor" and "vascular permeability factor". Although expressed at high levels in certain tumor-derived cells it is produced by a wide variety of cell types. In addition to stimulating vascular growth and vascular permeability it may play a role in stimulating VASODILATION via NITRIC OXIDE-dependent pathways. Alternative splicing of the mRNA for vascular endothelial growth factor A results in several isoforms of the protein being produced.Endothelial Cells: Highly specialized EPITHELIAL CELLS that line the HEART; BLOOD VESSELS; and lymph vessels, forming the ENDOTHELIUM. They are polygonal in shape and joined together by TIGHT JUNCTIONS. The tight junctions allow for variable permeability to specific macromolecules that are transported across the endothelial layer.Neovascularization, Physiologic: The development of new BLOOD VESSELS during the restoration of BLOOD CIRCULATION during the healing process.Apoptosis: One of the mechanisms by which CELL DEATH occurs (compare with NECROSIS and AUTOPHAGOCYTOSIS). Apoptosis is the mechanism responsible for the physiological deletion of cells and appears to be intrinsically programmed. It is characterized by distinctive morphologic changes in the nucleus and cytoplasm, chromatin cleavage at regularly spaced sites, and the endonucleolytic cleavage of genomic DNA; (DNA FRAGMENTATION); at internucleosomal sites. This mode of cell death serves as a balance to mitosis in regulating the size of animal tissues and in mediating pathologic processes associated with tumor growth.Annexin A5: A protein of the annexin family isolated from human PLACENTA and other tissues. It inhibits cytosolic PHOSPHOLIPASE A2, and displays anticoagulant activity.Cell Line, Tumor: A cell line derived from cultured tumor cells.P-Glycoprotein: A 170-kDa transmembrane glycoprotein from the superfamily of ATP-BINDING CASSETTE TRANSPORTERS. It serves as an ATP-dependent efflux pump for a variety of chemicals, including many ANTINEOPLASTIC AGENTS. Overexpression of this glycoprotein is associated with multidrug resistance (see DRUG RESISTANCE, MULTIPLE).Ovarian Neoplasms: Tumors or cancer of the OVARY.

It is composed of a specialized area of the plasma membrane where bundles of the ACTIN CYTOSKELETON terminate and attach to the transmembrane linkers, INTEGRINS, which in turn attach through their extracellular domains to EXTRACELLULAR MATRIX PROTEINS.Cell Adhesion: Adherence of cells to surfaces or to other cells.Actins: Filamentous proteins that are the main constituent of the thin filaments of muscle fibers. The filaments (known also as filamentous or F-actin) can be dissociated into their globular subunits; each subunit is composed of a single polypeptide 375 amino acids long. This is known as globular or G-actin. In conjunction with MYOSINS, actin is responsible for the contraction and relaxation of muscle.Molecular Sequence Data: Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.Cell-Matrix Junctions: Specialized areas at the CELL MEMBRANE where a cell attaches to the EXTRACELLULAR MATRIX or other substratum.Amino Acid Sequence: The order of amino acids as they occur in a polypeptide chain. This is referred to as the primary structure of proteins. It is of fundamental importance in determining PROTEIN CONFORMATION.Phosphorylation: The introduction of a phosphoryl group into a compound through the formation of an ester bond between the compound and a phosphorus moiety.Retinal Neovascularization: Formation of new blood vessels originating from the retinal veins and extending along the inner (vitreal) surface of the retina.Corneal Neovascularization: New blood vessels originating from the corneal veins and extending from the limbus into the adjacent CORNEAL STROMA. Neovascularization in the superficial and/or deep corneal stroma is a sequel to numerous inflammatory diseases of the ocular anterior segment, such as TRACHOMA, viral interstitial KERATITIS, microbial KERATOCONJUNCTIVITIS, and the immune response elicited by CORNEAL TRANSPLANTATION.Choroidal Neovascularization: A pathological process consisting of the formation of new blood vessels in the CHOROID.Research Support as Topic: Financial support of research activities.Research: Critical and exhaustive investigation or experimentation, having for its aim the discovery of new facts and their correct interpretation, the revision of accepted conclusions, theories, or laws in the light of newly discovered facts, or the practical application of such new or revised conclusions, theories, or laws.

Tyrosine-phosphorylated caveolin-1: immunolocalization and molecular characterization. (1/121)Caveolin-1 was discovered as a major substrate for v-Src, but the effect of its tyrosine phosphorylation has not been known. We generated a specific antibody (PY14) to caveolin-1 phosphorylated at tyrosine 14 and studied the significance of the modification. By Western blotting of lysates of v-Src-expressing cells, PY14 recognized not only a 22-kDa band (the position of nonphosphorylated caveolin-1) but bands at 23-24 and 25 kDa. Bands of slower mobility were diminished by dephosphorylation and were also observed for mutant caveolin-1 lacking tyrosine 14. By immunofluorescence microscopy, PY14 did not label normal cells but detected large dots in v-Src-expressing cells. Immunoelectron microscopy revealed that the dots corresponded to aggregated caveolae and/or vesicles of various sizes; besides, the label was observed in intramembrane particle-free areas in the plasma membrane, which appeared to have been formed by fusion of flattened caveolae. A positive reaction with PY14 was found in normal cells after vanadate or pervanadate treatment; it occurred mainly at 22 kDa by Western blotting and was not seen as large dots by immunofluorescence microscopy. Detergent solubility, oligomerization, and association with caveolin-2 were observed similarly for caveolin-1 in normal and v-Src-expressing cells. The results indicate that phosphorylation of caveolin-1 in v-Src-expressing cells occurs at multiple residues and induces flattening, aggregation, and fusion of caveolae and/or caveolae-derived vesicles.

Sequence and detailed organization of the human caveolin-1 and -2 genes located near the D7S522 locus (7q31.1). Methylation of a CpG island in the 5' promoter region of the caveolin-1 gene in human breast cancer cell lines. (2/121)The CA microsatellite repeat marker, D7S522, is located at the center of a approximately 1000 kb smallest common deleted region that is lost in many forms of human cancer. It has been proposed that a putative tumor suppressor gene lies in close proximity to D7S522, within this smallest common deleted region. However, the genes located in proximity to D7S522 have remained elusive. Recently, we identified five independent BAC clones (approximately 100-200 kb) containing D7S522 and the human genes encoding caveolins 1 and 2. Here, we present the detailed organization of the caveolin locus and its relationship to D7S522, as deduced using a shot-gun sequencing approach. We derived two adjacent contigs for a total coverage of approximately 250 kb. Analysis of these contigs reveals that D7S522 is located approximately 67 kb upstream of the caveolin-2 gene and that the caveolin-2 gene is located approximately 19 kb upstream of the caveolin-1 gene, providing for the first time a detailed genetic map of this region. Further sequence analysis reveals many interesting features of the caveolin genes; these include the intron-exon boundaries and several previously unrecognized CA repeats that lie within or in close proximity to the caveolin genes. The first and second exons of both caveolin genes are embedded within CpG islands. These results suggest that regulation of caveolin gene expression may be controlled, in part, by methylation of these CpG regions. In support of this notion, we show here that the CGs in the 5' promoter region of the caveolin-1 gene are functionally methylated in two human breast cancer cell lines (MCF7 and T-47D) that fail to express the caveolin-1 protein. In contrast, the same CGs in cultured normal human mammary epithelial cells (NHMECs) are non-methylated and these cells express high levels of the caveolin-1 protein. Comparison of the human locus with the same locus in the pufferfish Fugu rubripes reveals that the overall organization of the caveolin-1/-2 locus is conserved from pufferfish to man. In conclusion, our current studies provide a systematic basis for diagnostically evaluating the potential deletion, mutation, or methylation of the caveolin genes in a variety of human tumors.

The membrane-spanning domains of caveolins-1 and -2 mediate the formation of caveolin hetero-oligomers. Implications for the assembly of caveolae membranes in vivo. (3/121)The mammalian caveolin gene family consists of caveolins-1, -2, and -3. The expression of caveolin-3 is muscle-specific. In contrast, caveolins-1 and -2 are co-expressed, and they form a hetero-oligomeric complex in many cell types, with particularly high levels in adipocytes, endothelial cells, and fibroblasts. These caveolin hetero-oligomers are thought to represent the functional assembly units that drive caveolae formation in vivo. Here, we investigate the mechanism by which caveolins-1 and -2 form hetero-oligomers. We reconstituted this reciprocal interaction in vivo and in vitro using a variety of complementary approaches, including the generation of glutathione S-transferase fusion proteins and synthetic peptides. Taken together, our results indicate that the membrane-spanning domains of both caveolins-1 and -2 play a critical role in mediating their ability to interact with each other. This is the first demonstration that these unusual membrane-spanning regions found in the caveolin family play a specific role in protein-protein interactions. (+info)
Vimentin-dependent utilization of LDL-cholesterol in human adrenal tumor cells is not associated with the level of expression of apoE, sterol carrier protein-2, or caveolin. (4/121)SW-13 adrenal tumor cells that lack detectable intermediate filaments (IF-free) exhibit an impaired capacity to esterify lipoprotein-derived cholesterol compared with cells that contain vimentin filaments. IF-free cells were found to synthesize and secrete significant amounts of apoE, while apoE secretion was nearly undetectable in cell lines that spontaneously express vimentin. However, stable transfectants that express a mouse vimentin cDNA exhibited elevated levels of cholesterol esterification and apoE secretion compared with untransfected IF-free cells, indicating that apoE secretion is not directly related to the capacity of these cells to esterify cholesterol. Some of the cell lines that differed in the level of apoE synthesis and secretion had similar levels of apoE mRNA, suggesting that the differences in expression involve a post-transcriptional mechanism. Treatment of these cells with forskolin and IBMX, 8br-cAMP, or TPA had no effect on apoE secretion. The level of sterol carrier protein-2 (SCP(2)) synthesis and the distribution of SCP(2) between membrane and soluble cellular fractions was not observably different in cells that contained or lacked vimentin. SW-13 cell lines contained little or no detectable caveolin-1 or caveolin-2. These studies demonstrate that the difference in the capacity of these adrenal tumor cells that contain or lack vimentin filaments to esterify low density lipoprotein-cholesterol is not obviously associated with the level of expression or distribution of apoE, SCP(2), or caveolins.

Caveolin-2 localizes to the golgi complex but redistributes to plasma membrane, caveolae, and rafts when co-expressed with caveolin-1. (5/121)We have characterized comparatively the subcellular distributions of caveolins-1 and -2, their interactions and their roles in caveolar formation in polarized epithelial cells. In Fischer rat thyroid (FRT) cells, which express low levels of caveolin-2 and no caveolin-1, caveolin-2 localizes exclusively to the Golgi complex but is partially redistributed to the plasma membrane upon co-expression of caveolin-1 by transfection or by adenovirus-mediated transduction. In Madin-Darby canine kidney (MDCK) cells, which constitutively express both caveolin-1 and -2, caveolin-2 localized to both the Golgi complex and to the plasma membrane, where it co-distributed with caveolin-1 in flat patches and in caveolae. In FRT cells, endogenous or overexpressed caveolin-2 did not associate with low density Triton insoluble membranes that floated in sucrose density gradients but was recruited to these membranes when co-expressed together with caveolin-1. In MDCK cells, both caveolin-1 and caveolin-2 associated with low density Triton-insoluble membranes. In FRT cells, transfection of caveolin-1 promoted the assembly of plasma membrane caveolae that localized preferentially (over 99%) to the basolateral surface, like constitutive caveolae of MDCK cells. In contrast, as expected from its intracellular distribution, endogenous or overexpressed caveolin-2 did not promote the assembly of caveolae; rather, it appeared to promote the assembly of intracellular vesicles in the peri-Golgi area. The data reported here demonstrate that caveolin-1 and -2 have different and complementary subcellular localizations and functional properties in polarized epithelial cells and suggest that the two proteins co-operate to carry out specific as yet unknown tasks between the Golgi complex and the cell surface.

Expression of caveolin-1 is required for the transport of caveolin-2 to the plasma membrane. Retention of caveolin-2 at the level of the golgi complex. (6/121)Caveolins-1 and -2 are normally co-expressed, and they form a hetero-oligomeric complex in many cell types. These caveolin hetero-oligomers are thought to represent the assembly units that drive caveolae formation in vivo. However, the functional significance of the interaction between caveolins-1 and -2 remains unknown. Here, we show that caveolin-1 co-expression is required for the transport of caveolin-2 from the Golgi complex to the plasma membrane. We identified a human erythroleukemic cell line, K562, that expresses caveolin-2 but fails to express detectable levels of caveolin-1. This allowed us to stringently assess the effects of recombinant caveolin-1 expression on the behavior of endogenous caveolin-2. We show that expression of caveolin-1 in K562 cells is sufficient to reconstitute the de novo formation of caveolae in these cells. In addition, recombinant expression of caveolin-1 allows caveolin-2 to form high molecular mass oligomers that are targeted to caveolae-enriched membrane fractions. In striking contrast, in the absence of caveolin-1 expression, caveolin-2 forms low molecular mass oligomers that are retained at the level of the Golgi complex. Interestingly, we also show that expression of caveolin-1 in K562 cells dramatically up-regulates the expression of endogenous caveolin-2. Northern blot analysis reveals that caveolin-2 mRNA levels remain constant under these conditions, suggesting that the expression of caveolin-1 stabilizes the caveolin-2 protein. Conversely, transient expression of caveolin-2 in CHO cells is sufficient to up-regulate endogenous caveolin-1 expression. Thus, the formation of a hetero-oligomeric complex between caveolins-1 and -2 stabilizes the caveolin-2 protein product and allows caveolin-2 to be transported from the Golgi complex to the plasma membrane.

Caveolin-1 inhibits epidermal growth factor-stimulated lamellipod extension and cell migration in metastatic mammary adenocarcinoma cells (MTLn3). Transformation suppressor effects of adenovirus-mediated gene delivery of caveolin-1. (7/121)Caveolin-1 is a principal component of caveolae membranes that may function as a transformation suppressor. For example, the human caveolin-1 gene is localized to a suspected tumor suppressor locus (D7S522; 7q31.1) that is deleted in human cancers, including mammary carcinomas. However, little is known about the role of caveolins in regulating cell movement, a critical parameter in determining metastatic potential. Here, we examine the role of caveolin-1 in cell movement. For this purpose, we employed an established cellular model, MTLn3, a metastatic rat mammary adenocarcinoma cell line. In this system, epidermal growth factor (EGF) stimulation induces rapid lamellipod extension and cell migration. Interestingly, we find that MTLn3 cells fail to express detectable levels of endogenous caveolin-1. To restore caveolin-1 expression in MTLn3 cells efficiently, we employed an inducible adenoviral gene delivery system to achieve tightly controlled expression of caveolin-1. We show here that caveolin-1 expression in MTLn3 cells inhibits EGF-stimulated lamellipod extension and cell migration and blocks their anchorage-independent growth. Under these conditions, EGF-induced activation of the p42/44 mitogen-activated protein kinase cascade is also blunted. Our results suggest that caveolin-1 expression in motile MTLn3 cells induces a non-motile phenotype. (+info)
A molecular dissection of caveolin-1 membrane attachment and oligomerization. Two separate regions of the caveolin-1 C-terminal domain mediate membrane binding and oligomer/oligomer interactions in vivo. (8/121)Caveolins form interlocking networks on the cytoplasmic face of caveolae. The cytoplasmically directed N and C termini of caveolins are separated by a central hydrophobic segment, which is believed to form a hairpin within the membrane. Here, we report that the caveolin scaffolding domain (CSD, residues 82-101), and the C terminus (residues 135-178) of caveolin-1 are each sufficient to anchor green fluorescent protein (GFP) to membranes in vivo. We also show that the first 16 residues of the C terminus (i.e. residues 135-150) are necessary and sufficient to attach GFP to membranes. When fused to the caveolin-1 C terminus, GFP co-localizes with two trans-Golgi markers and is excluded from caveolae. In contrast, the CSD targets GFP to caveolae, albeit less efficiently than full-length caveolin-1. Thus, caveolin-1 contains at least two membrane attachment signals: the CSD, dictating caveolar localization, and the C terminus, driving trans-Golgi localization. Additionally, we find that caveolin-1 oligomer/oligomer interactions require the distal third of the caveolin-1 C terminus. Thus, the caveolin-1 C-terminal domain has two separate functions: (i) membrane attachment (proximal third) and (ii) protein/protein interactions (distal third). (+info)

Caveolin-3 is a protein that in humans is encoded by the CAV3 gene. Alternative splicing has been identified for this locus, with inclusion or exclusion of a differentially spliced intron. In addition, transcripts utilize multiple polyA sites and contain two potential translation initiation sites. This gene encodes a caveolin family member, which functions as a component of the caveolae plasma membranes found in most cell types. Caveolin proteins are proposed to be scaffolding proteins for organizing and concentrating certain caveolin-interacting molecules. Mutations identified in this gene lead to interference with protein oligomerization or intra-cellular routing, disrupting caveolae formation and resulting in Limb-Girdle muscular dystrophy type-1C (LGMD-1C), HyperCKemia, distal myopathy or rippling muscle disease (RMD). Other mutations in Caveolin causes Long QT Syndrome or familial hypertrophic cardiomyopathy, although the role of Cav3 in Long QT syndrome has recently been disputed. Caveolin ...

Caveolae. Caveolae were described in the fifties of the last century by P. Palade after observing animal tissues at transmission electron microscopy. They are small invaginations (45-80 nm) of the plasma membrane that can be observed in most of the eukaryotic cells. It was suggested that most of the caveolae become vesicles (but see below). Caveolae are abundant in endothelial cells, muscle cells and adipocytes. The membrane of the caveolae contains caveolin, as well as other integral proteins linked to glycosylphosphatidylinositol, many sphingolipids (sphingomyelin and glycosphingolipids), and is enriched in cholesterol. The presence of caveolin in a cell is enought to form caveolae. There are around 100 to 200 caveolin molecules in one caveola and there are different types of caveolin in one caveola. Caveolin 1 is expressed in smooth muscle cells and in most of the non muscle cells, and it is necessary for caveolae formation in these cells. Caveolin 2, which can be expressed in the same cells ...

Angiogenic growth factor-induced endothelial cell migration is a key step towards tumor angiogenesis. When cells are migrating, caveolin-1, the principle protein component of caveolae, is excluded from the leading edge and polarized to the cell rear. The migration-stimulated caveolin rear translocation appears to play an important role in endothelial cell polarization and directional movement. In

Caveolins act as scaffold proteins in multiprotein complexes and have been implicated in signaling by G protein-coupled receptors. Studies using knock-out mice suggest that beta(3)-adrenoceptor (beta(3)-AR) signaling is dependent on caveolin-1; however, it is not known whether caveolin-1 is associated with the beta(3)-AR or solely with downstream signaling proteins. We have addressed this question by examining the impact of membrane rafts and caveolin-1 on the differential signaling of mouse beta(3a)- and beta(3b)-AR isoforms that diverge at the distal C terminus. Only the beta(3b)-AR promotes pertussis toxin (PTX)-sensitive cAMP accumulation. When cells expressing the beta(3a)-AR were treated with filipin III to disrupt membrane rafts or transfected with caveolin-1 siRNA, the cyclic AMP response to the beta(3)-AR agonist CL316243 became PTX-sensitive, suggesting G alpha(i/o) coupling.

This work establishes an impact of cavin‐1 on pressure regulation in the pulmonary circulation. Right ventricular systolic pressure was robustly increased compared to WT littermate controls and accompanied by an increased right ventricular mass and remodeling of airway‐associated blood vessels. Because PAH is a progressive disease and we used younger animals, one may predict a more full‐blown PAH phenotype with aging. Since expression of caveolin‐1 was partly maintained, cavin‐1‐knockout mice may constitute a more adequate model of heritable PAH due to mutations in caveolin‐1 than do caveolin‐1‐knockout mice. This is because the disease‐causing mutations cause a partial reduction of caveolin‐1 (Austin et al. 2012), contrasting with the situation in caveolin‐1‐knockout mice where the protein is completely lacking.. In agreement with our current findings, thicker alveolar septa, hypercellularity, and elevated pulmonary pressure have been reported in ...

Caveolin is the principal protein of caveolae and has been implicated in the pathogenesis of cerebral ischemia. To investigate whether changed expression of caveolins has a pivotal role in focal cerebral ischemia, we induced middle cerebral artery occlusion (MCAo)-reperfusion and examined expression of caveolins, inflammatory activation markers, and mediators of autophagic cell death. We also treated MCAo rats with forced exercise to determine its effects on neurological outcome. Particularly, spontaneously hypertensive rats (SHR) and normotensive Wistar-Kyoto (WKY) rats were used to compare the effects of hypertension on focal cerebral ischemia. All MCAo groups showed neurological deficiencies, motor dysfunction, and disruption of balancing ability; however, these pathological changes were more severe in SHR than WKY rats. Expression of caveolins was decreased in MCAo brain tissue, whereas the levels of iNOS and glial fibrillary acidic protein (GFAP) increased. Additionally, LC3-II and beclin-1 levels

Proteins and other substances can cross the endothelial layer that lines a blood vessel via two routes. Caveolin-1 is essential for both, Siddiqui et al. show.. Researchers already knew that caveolin-1 was necessary for transcellular protein trafficking, in which macromolecules such as albumin enter an endothelial cell from the bloodstream and exit on the tissue side. Caveolae swallow these molecular travelers and bundle them into vesicles that wend through the cell. In an alternative pathway, known as the paracellular route, molecules slip between the cells of the endothelial layer, passing through the adherens junctions that fasten adjacent cells together. Previous work showed that adherens junctions become permeable in mice lacking caveolin-1, suggesting that the protein helps seal the junctions.. Siddiqui et al. dissected the molecular chain of events that connects caveolin-1 to adherens junction integrity. Loss of caveolin-1 activated the enzyme eNOS, which spawns nitric oxide (NO) that ...

Abstract 15887: MURC/cavin-4 Functions as a Negative Regulator of Caveolin-3 in Tte Development of Heart Failure | Circulation
Background: Muscle-restricted coiled-coil protein (MURC)/cavin-4 is a novel member of the cavin family that regulates caveolae function. Caveolae formation and function are also regulated by caveolin-3 in cardiomyocytes (CMs). Overexpression of caveolin-3 induces cardiac protection, and loss of caveolin-3 causes progressive cardiomyopathy. Mutations in MURC have been identified in patients with dilated cardiomyopathy. However, the role of MURC as a caveolar component protein remains unknown.. Methods and Results: To assess the role of MURC in the development of heart failure, MURC-knockout (KO) and wild-type (WT) mice were subjected to pressure overload by transverse aortic constriction (TAC). After TAC, WT mice developed overt heart failure and eccentric cardiac hypertrophy, whereas MURC-KO mice showed preserved cardiac function accompanied by attenuated cardiac hypertrophy. We then focused on β-adrenergic receptor (AR) signaling, because MURC was colocalized and associated with β1-AR. ...
Summary is not available for the mouse gene. This summary is for the human ortholog.] The scaffolding protein encoded by this gene is the main component of the caveolae plasma membranes found in most cell types. The protein links integrin subunits to the tyrosine kinase FYN, an initiating step in coupling integrins to the Ras-ERK pathway and promoting cell cycle progression. The gene is a tumor suppressor gene candidate and a negative regulator of the Ras-p42/44 mitogen-activated kinase cascade. Caveolin 1 and caveolin 2 are located next to each other on chromosome 7 and express colocalizing proteins that form a stable hetero-oligomeric complex. Mutations in this gene have been associated with Berardinelli-Seip congenital lipodystrophy. Alternatively spliced transcripts encode alpha and beta isoforms of caveolin 1.[provided by RefSeq, Mar 2010 ...
In biology, caveolae (Latin for "little caves"; singular, caveola), which are a special type of lipid raft, are small (50-100 nanometer) invaginations of the plasma membrane in many vertebrate cell types, especially in endothelial cells, adipocytes and embryonic notochord cells. They were originally discovered by E. Yamada in 1955. These flask-shaped structures are rich in proteins as well as lipids such as cholesterol and sphingolipids and have several functions in signal transduction. They are also believed to play a role in mechanoprotection, mechanosensation, endocytosis, oncogenesis, and the uptake of pathogenic bacteria and certain viruses. Formation and maintenance of caveolae was initially thought to be primarily due to caveolin, a 21 kD protein. There are three homologous genes of caveolin expressed in mammalian cells: Cav1, Cav2 and Cav3. These proteins have a common topology: cytoplasmic N-terminus with scaffolding domain, long hairpin transmembrane domain and cytoplasmic C-terminus. ...

The plasma membrane is not uniform, but can be divided into different microdomains. Whereas some microdomains, such as clathrin-coated pits, are morphologically identifiable, others can be identified only upon colocalization with domain-specific marker molecules. Caveolae are microdomains originally identified morphologically as small noncoated invaginations of the plasma membrane. The formation of caveolae depends on expression of caveolin and, since the plasma membrane contains different noncoated invaginations, caveolae can be identified only by labeling for caveolin. Some confusion exists with respect to the relationship between caveolae and lipid rafts [see raft nomenclature ( Simons and Toomre, 2000)]. This is partly due to difficulties in isolating pure caveolae and to the various methods used for this purpose. Initially, subcellular fractionation upon Triton X-100 extraction at 4°C was used. Such fractionation allows the isolation of detergent-resistant membranes [DRMs; also called DIGs ...
This gene encodes a protein that enables the dissociation of paused ternary polymerase I transcription complexes from the 3 end of pre-rRNA transcripts. This protein regulates rRNA transcription by promoting the dissociation of transcription complexes and the reinitiation of polymerase I on nascent rRNA transcripts. This protein also localizes to caveolae at the plasma membrane and is thought to play a critical role in the formation of caveolae and the stabilization of caveolins. This protein translocates from caveolae to the cytoplasm after insulin stimulation. Caveolae contain truncated forms of this protein and may be the site of phosphorylation-dependent proteolysis. This protein is also thought to modify lipid metabolism and insulin-regulated gene expression. Mutations in this gene result in a disorder characterized by generalized lipodystrophy and muscular dystrophy. [provided by RefSeq, Nov 2009 ...

Phosphorylation of caveolin-1 plays a fundamental role in the mechanism of oxidant-induced vascular hyper permeability. However, the regulatory mechanism of caveolin-1 phosphorylation remains unclear. Here we identify a previously unexpected role for AMPKin inhibition of caveolin-1 phosphorylation under oxidative stress. A pharmacological activator of AMPK, ...
Shibata and colleagues have shown previously that the application of peptides derived from the Gαs sequence in inside-out macropatches enhanced isoproterenol-evoked sodium current (INa), attributable to an apparent increase in the number of functional channels.5,6⇓ In this issue of Circulation Research, Shibata and colleagues (Yarbrough et al8) report that the source of these new channels could be caveolae. Using antibodies directed against caveolin-3, the muscle-specific isoform of caveolin, these investigators were able to block the direct effect of isoproterenol on the Na+ channel (ie, the PKA-independent, Gαs membrane-delimited pathway). Importantly, this effect seems specific, given that antibodies directed against other caveolin isoforms did not affect isoproterenol activation of Na+ channel activity. Moreover, Yarbrough et al8 also documented, in cardiac myocytes, the apparent preferential enrichment into caveolar microdomains of Na+ channels and Gαs. Although these data led the ...
Caveolae are specialised forms of lipid rafts in the plasma membrane of most cells. They form dynamic assemblies of sphingolipids and cholesterol containing scaffolding domains with different affinities for proteins resulting in a variety of functions . The constitutive Cav-1 protein is distributed ubiquitously, while Cav-2 is usually associated with Cav-1 [3, 28]. Although Cav-3 is thought to be "muscle specific" and is expressed in striated muscles [3, 28, 29], we and others have found that Cav-3 is not expressed within human ASM [6, 30]. Recent studies have established that ASM caveolae contain a number of proteins important to [Ca2+]i regulation (e.g. agonist receptors, Ca2+ influx channels, and force regulatory proteins such as RhoA). In canine ASM, it has been established that caveolar-enriched membrane fractions express Cav-1, L-type Ca2+ channels and plasma membrane Ca2+ ATPase, but not SR proteins such as IP3R or RyR channels .. In ASM of different species, in addition to Ca2+ ...

Caveolin-1 regulates leucocyte behaviour in fibrotic lung disease | Annals of the Rheumatic Diseases
Objectives Reduced caveolin-1 levels in lung fibroblasts from patients with scleroderma and the lungs of bleomycin-treated mice promote collagen overexpression and lung fibrosis. This study was undertaken to determine whether caveolin-1 is deficient in leucocytes from bleomycin-treated mice and patients with scleroderma and to examine the consequences of this deficiency and its reversal.. Methods Mice or cells received the caveolin-1 scaffolding domain (CSD) peptide to reverse the pathological effects of reduced caveolin-1 expression. In bleomycin-treated mice, the levels of caveolin-1 in leucocytes and the effect of CSD peptide on leucocyte accumulation in lung tissue were examined. To validate the results in human disease and to identify caveolin-1-regulated molecular mechanisms, monocytes and neutrophils were isolated from patients with scleroderma and control subjects and caveolin-1, extracellular signal-regulated protein kinase (ERK), c-Jun N-terminal kinase (JNK), p38, CXC chemokine ...
At the European Molecular Biology Laboratory (EMBL) in Heidelberg, Professor Parton was mentored by Gareth Griffiths, where he honed his skills in electron microscopy while collaborating with other groups throughout the institute including Jean Gruenberg and Marino Zerial. He has maintained these collaborations to this day, despite the groups now being spread around the globe.. Collaboration has been central to his career. In a collaborative project with the laboratory of Kai Simons, he observed that the newly-discovered protein, VIP21 (later renamed caveolin-1), was an abundant marker protein of caveolae. Also at the EMBL Parton and Michael Way discovered a second member of the caveolin family, M-caveolin, now termed caveolin-3.. At The University of Queensland he collaborated with Professor John Hancock. Together they showed that caveolin mutants can act as dominant negative inhibitory mutants and that one of the mutants was a highly potent inhibitor of Ras signalling. Inhibition was specific ...
