Gene expression and methylation of matrix metalloproteinase-13 and osteoarthritis & Burden of risk alleles for complex traits in the Newfoundland and Labrador population
PART I To evaluate the role of MMP-13, a catabolic enzyme, in osteoarthritis (OA) pathogenesis, we utilized a case-control study design to analyze cartilage samples obtained from 48 OA patients and 30 healthy controls. We found that MMP-13 expression was significantly increased in OA-affected cartil...
