PLoS One . 2012 May; 7(4):e35040. PMID: 22545096
Matrix metalloproteinases (Mmps) stimulate tumor invasion and metastasis by degrading the extracellular matrix. Here we reveal an unexpected role for Mmp10 (stromelysin 2) in the maintenance and tumorigenicity of mouse...

Am J Physiol Cell Physiol . 2011 Oct; 302(2):C453-62. PMID: 22031598
Matriptase proteolytic activity must be tightly controlled for normal placental development, epidermal function, and epithelial integrity. Although hepatocyte growth factor activator inhibitor-1 (HAI-1) represents the predominant endogenous inhibitor for matriptase...

J Biol Chem . 2009 Nov; 285(5):3261-70. PMID: 19940125
Extracellular acidosis often rapidly causes intracellular acidification, alters ion channel activities, and activates G protein-coupled receptors. In this report, we demonstrated a novel cellular response to acidosis: induction of the...
