The cerebrovascular remodeling is a prominent feature of hypertension and considered a major risk factor for stroke. Cerebrovascular smooth muscle cells meet volume challenge during this pathophysiological process. Our previous studies suggest that volume regulated chloride channels may be critical to the cell cycle of vascular smooth muscle cells. However, it is unknown whether the volume-regu...
BACKGROUND AND PURPOSE Serotonin is one of the most potent constrictors of cerebral blood vessels and is implicated in several pathological conditions, including migraine and cerebral ischemia. Recent evidence has suggested that tyrosine kinase is involved in vasocontractile responses. The objective of this study was to test the hypothesis that activation of tyrosine kinase contributes to serot...
Peptide hormone somatostatin and its receptors have a wide range of physiological functions and play a role in the treatment of numerous human diseases, including colorectal cancer. Octreotide, a synthetic somatostatin-analog peptide, inhibits growth of colonic cancer cells primarily by binding to G-protein coupled receptors and elicits cellular responses through second-messenger systems. Insul...
We have previously shown that during wound healing migrating keratinocytes, which are in contact with the dermal matrix, express interstitial collagenase, whereas basal epidermal cells, which reside on an intact basement membrane, do not. Duplicating this in vivo pattern, collagenase production was induced in primary human keratinocytes grown on native type I collagen, but only background level...
ConA-induced cell surface activation of pro-matrix metalloproteinase-2 (pro-MMP-2) by MDA-MB-231 human breast cancer cells is apparently mediated by up-regulation of membrane type 1 MMP (MT1-MMP) through transcriptional and posttranscriptional mechanisms. Here, we have explored the respective roles of cell surface clustering and protein tyrosine phosphorylation in the ConA-induction effects. Tr...
