Liposomal Tumor Targeting in Drug Delivery Utilizing MMP-2- and MMP-9-Binding Ligands

Liposomal Tumor Targeting in Drug Delivery Utilizing MMP-2- and MMP-9-Binding Ligands

Nanotechnology offers an alternative to conventional treatment options by enabling different drug delivery and controlled-release delivery strategies. Liposomes being especially biodegradable and in most cases essentially nontoxic offer a versatile platform for several different delivery approaches that can potentially enhance the delivery and targeting of therapies to tumors. Liposomes penetra...

Investigation of MMP-2 and MMP-9 activities in canine sera with dilated cardiomyopathy

Dilated cardiomyopathy (DCM) is accompanied by myocytes and connective tissue changes. Matrix metalloproteinases (MMPs) play important roles in cardiac remodeling. It seems that the gelatinases (MMP-2 and MMP-9) are effective enzymes in cardiomyopathy. Dilated cardiomyopathy was confirmed in 22 dogs (patient group) including 11 female and 11 male by clinical examination, auscultation, thoracic ...

Activation of MMP‐9 by membrane type‐1 MMP/MMP‐2 axis stimulates tumor metastasis

An artificial receptor for proMMP-9 was created by fusing tissue inhibitor of MMP-1 (TIMP-1) with type II transmembrane mosaic serine protease (MSP-T1). Expression of MSP-T1 in 293T cells induced binding of proMMP-9, which was processed by MMP-2 activated by membrane type 1 MMP (MT1-MMP). HT1080 cells transfected with the MSP-T1 gene produced activated MMP-9 in collagen gel, and addition of pro...

MMP-2 and MMP-9 synergize in promoting choroidal neovascularization.

Matrix metalloproteinase 2 (MMP-2) and MMP-9 are increased in human choroidal neovascularization (CNV) occurring during the exudative most aggressive form of age-related macular degeneration (AMD), but their precise role and potential interactions remain unclear. To address the question of MMP-2 and MMP-9 functions, mice deficient in the expression of MMP-2 (MMP-2 KO), MMP-9 (MMP-9 KO), and bot...
