Caveolin and GLT-1 gene expression is reciprocally regulated in primary astrocytes: Association of GLT-1 with non-caveolar lipid rafts

2004

Caveolae represent membrane microdomains acting as integrators of cellular signaling and functional processes. Caveolins are involved in the biogenesis of caveolae and regulate the activity of caveolae-associated proteins. Although caveolin proteins are found in the CNS, the regulation of caveolins in neural cells is poorly described. In the present study, we investigated different modes and mechanisms of caveolin gene regulation in primary rat astrocytes. We demonstrated that activation of cAMP-dependent signaling pathways led to a marked reduction in protein levels of caveolin-1/-2 in cortical astrocytes. Application of transforming growth factor-alpha (TGF-alpha) also resulted in a decre…

Differential Promotion of Glutamate Transporter Expression and Function by Glucocorticoids in Astrocytes from Various Brain Regions

2005

Steroids that activate glucocorticoid receptors (GRs) and mineralocorticoid receptors have important regulatory effects on neural development, plasticity, and the body's stress response. Here, we investigated the role of corticosteroids in regulating the expression of the glial glutamate transporters glial glutamate transporter-1 (GLT-1) and glutamate-aspartate transporter (GLAST) in rat primary astrocytes. The synthetic glucocorticoid dexamethasone provoked a marked increase of GLT-1 transcription and protein levels in cortical astrocytes, whereas GLAST expression remained unaffected. Up-regulation of GLT-1 expression was accompanied by an enhanced glutamate uptake, which could be blocked …

Functional interaction of estrogen receptor α and caveolin isoforms in neuronal SK-N-MC cells

2003

Estrogen receptors (ERs) are expressed in neuronal cells and exhibit a wide variety of activities in the central nervous system. The actions of ERs are regulated in a hormone-dependent manner as well as by a number of co-activators and -repressors. A recently identified co-activator of ERalpha is caveolin-1 which has been shown to mediate the ligand-independent activation of this steroid receptor. In the present study we have demonstrated that neuronal SK-N-MC cells lacking functional ERalpha show high levels of caveolin-1/-2 specific transcripts and proteins. Ectopic expression of ERalpha in SK-N-MC cells leads to the transcriptional suppression of caveolin-1 and -2 genes. This silencing e…
