Matrix metalloproteinases (MMPs) are essential for proper extracellular matrix remodeling, a process that takes place during obesity-mediated adipose tissue formation. Here, we examine expression profiles and the potential role of MMPs and their tissue inhibitors (TIMPs) in adipose tissue remodeling during obesity. Expression patterns are studied by(More)
Several lines of evidence suggest a role for laminin-5 in skin wound healing. We report here that transforming growth factor-beta (TGF-beta), which elicits various responses during cutaneous healing, stimulates transcription of the mouse laminin alpha3A (lama3A) gene. To identify the TGF-beta-responsive elements (TGFbeta-REs) on the lama3A promoter, we have(More)
Alterations in the expression level of genes may contribute to the development and pathophysiology of obesity. To find genes differentially expressed in adipose tissue during obesity, we performed suppression subtractive hybridization on epididymal fat mRNA from goldthioglucose (GTG) obese mice and from their lean littermates. We identified the secreted(More)
Vav1 and Vav2 are members of the Dbl family of guanine nucleotide exchange factors for the Rho family of small GTPases. Although the role of Vav1 during lymphocyte development and activation is well characterized, the function of Vav2 is still unclear. In this study, we compared the signaling pathways regulated by Vav1 and Vav2 following engagement of the T(More)
