A metalloprotease that digests cartilage proteoglycan optimally at pH 5.3 has been purified (4400-fold) to homogeneity from 20-g samples of human articular cartilage containing about 100 micrograms of enzyme. This enzyme was cleanly separated from a related neutral metalloprotease with an optimum pH of 7.2. The acid metalloprotease displays 40% of its maximum activity at pH 7.2 and so has signi...
BACKGROUND Squamous dysplasia is the precursor lesion for esophageal squamous cell carcinoma (ESCC). A primary screening test for ESCC which identified this lesion could lead to a reduction in disease-specific mortality. MATERIALS AND METHODS We conducted a population-based screening study in Linzhou, China. All subjects provided blood samples and underwent endoscopy with Lugol's iodine stain...
BACKGROUND Insulin is a vital peptide hormone that is a central regulator of glucose homeostasis, and impairments in insulin signaling cause diabetes mellitus. In principle, it should be possible to enhance the activity of insulin by inhibiting its catabolism, which is mediated primarily by insulin-degrading enzyme (IDE), a structurally and evolutionarily distinctive zinc-metalloprotease. Despi...
