Evaluation of apoptogenic adenovirus type 5 oncolytic vectors in a Syrian hamster head and neck cancer model.

Human adenovirus (HAdV) vectors are intensely investigated for virotherapy of a wide variety of human cancers. Here, we have evaluated the effect of two apoptogenic HAdV5 vectors in an immunocompetent Syrian hamster animal model of head and neck cancer. We established two cell lines of hamster cheek pouch squamous cell carcinomas, induced by treatment with 9,10-dimethyl-1,2-benzanthracene.

Reversal of the adynamic bone disorder and decreased vascular calcification in chronic kidney disease by sevelamer carbonate therapy.

A model of chronic kidney disease (CKD)-induced vascular calcification (VC) that complicates the metabolic syndrome was produced. In this model, the metabolic syndrome is characterized by severe atherosclerotic plaque formation, hypertension, type 2 diabetes, obesity, and hypercholesterolemia, and CKD stimulates calcification of the neointima and tunica media of the aorta. The CKD in this model is associated the adynamic bone disorder form of renal osteodystrophy.

Bone morphogenic protein-7 (BMP-7), a novel therapy for diabetic nephropathy.

Background: Bone morphogenic protein-7 (BMP-7), an essential developmental renal morphogen, is a secreted differentiation factor of the adult collecting duct. It activates receptors in the collecting duct, distal nephron, proximal tubule, and glomerulus. BMP-7 is therapeutic in tubulointerstitial nephritis raising the question of broader efficacy in chronic kidney disease (CKD).
