How Avrin works
Avrin's active metabolite rhein Rhein reduces cartilage destruction by decreasing expression of matrix metalloproteinase (MMP)-1 and -3 as well as upregulating tissue inhibitor of matrix metalloproteinases which serve to reduce the activity of several MMPs . The anti-inflammatory action of rhein reduces the level of interleukin-1beta activity which plays a large role in reduction of extracellular matrix production, MMP activity, and continued inflammation . Rhein reduces abnormal osteoblast synthetic activity through an unknown mechanism .
