1 Using membranes prepared from adult rat cardiac myocytes and fibroblasts, we found that MMP14 activity is increased by angiotensin II, phenylephrine, GTP, and guanosine 5"-O-[gamma-thio]triphosphate (GTPgammaS). Phenylephrine matrix metallopeptidase 14 Rattus norvegicus
2 Using membranes prepared from adult rat cardiac myocytes and fibroblasts, we found that MMP14 activity is increased by angiotensin II, phenylephrine, GTP, and guanosine 5"-O-[gamma-thio]triphosphate (GTPgammaS). Guanosine Triphosphate matrix metallopeptidase 14 Rattus norvegicus
3 Using membranes prepared from adult rat cardiac myocytes and fibroblasts, we found that MMP14 activity is increased by angiotensin II, phenylephrine, GTP, and guanosine 5"-O-[gamma-thio]triphosphate (GTPgammaS). guanosine 5"-o-[gamma-thio]triphosphate matrix metallopeptidase 14 Rattus norvegicus
4 Using membranes prepared from adult rat cardiac myocytes and fibroblasts, we found that MMP14 activity is increased by angiotensin II, phenylephrine, GTP, and guanosine 5"-O-[gamma-thio]triphosphate (GTPgammaS). GTPgammaS matrix metallopeptidase 14 Rattus norvegicus
5 MMP14 activation by GTPgammaS occurs in a concentration- and time-dependent manner, does not occur in response to GMP or adenosine 5"-[gamma-thio]triphosphate (ATPgammaS), and is not blunted by inhibitors of Src, PKC, phospholipase C (PLC), PI3K, or soluble MMPs. GTPgammaS matrix metallopeptidase 14 Rattus norvegicus
6 MMP14 activation by GTPgammaS occurs in a concentration- and time-dependent manner, does not occur in response to GMP or adenosine 5"-[gamma-thio]triphosphate (ATPgammaS), and is not blunted by inhibitors of Src, PKC, phospholipase C (PLC), PI3K, or soluble MMPs. GTPgammaS matrix metallopeptidase 14 Rattus norvegicus
7 MMP14 activation by GTPgammaS occurs in a concentration- and time-dependent manner, does not occur in response to GMP or adenosine 5"-[gamma-thio]triphosphate (ATPgammaS), and is not blunted by inhibitors of Src, PKC, phospholipase C (PLC), PI3K, or soluble MMPs. adenosine 5'-O-(3-thiotriphosphate) matrix metallopeptidase 14 Rattus norvegicus
8 GTPgammaS-stimulated activation of MMP14 also results in membrane release of HB-EGF and the activation of EGFR. GTPgammaS matrix metallopeptidase 14 Rattus norvegicus
