The MMP-3 enzyme degrades collagen types II, III, IV, IX, and X, proteoglycans, fibronectin, laminin, and elastin. In addition, MMP-3 can also activate other MMPs such as MMP-1, MMP-7, and MMP-9, rendering MMP-3 crucial in connective tissue remodeling.
What is mmp13 enzyme?
Matrix metalloproteinase (MMP) 13 is a major enzyme that targets cartilage for degradation. It not only targets type II collagen in cartilage for degradation, but also degrades proteoglycan, types IV and type IX collagen, osteonectin and perlecan in cartilage [4].
What is MMP 3 test?
MMP-3 in serum is quantitated using an ELISA (Enzyme linked immunosorbent assay) procedure. It is a two-step sandwich-type immunoassay using two antibodies to MMP-3; monoclonal antibody is the capture antibody and signal polyclonal antibody is conjugated with horse-raddish peroxidase (HRP).
What is a TIMP?
plural noun. (sometimes functioning as singular) a set of kettledrums, two or more in number. Often (informal) shortened to: timps.
What reduces MMP-13?
Conclusions: Knee loading reduces MMP13 activity at least in part through Rac1-mediated p38 MAPK signaling. This study suggests the possibility of knee loading as a therapy not only for strengthening bone but also preventing tissue degradation of the femoral cartilage.
Does MMP-13 cause neuropathy?
Finally, we show that MMP-13 dysregulation also underlies paclitaxel-induced peripheral neuropathy in mammals, indicating that epidermal mitochondrial H2O2 and its effectors could be targeted for therapeutic interventions.
How many MMPs does a human have?
23 MMPs
Various types of proteinases are implicated in ECM degradation, but the major enzymes are considered to be matrix metalloproteinases (MMPs), also called matrixins [4]. Humans have 24 matrixin genes including duplicated MMP-23 genes; thus there are 23 MMPs in humans.
