What are MMP-2 and MMP-9?
Matrix metalloproteinases (MMPs) are a family of zinc-dependent proteases, and MMP-2 and MMP-9 are major members of the MMP family (6,7). MMP-2 and MMP-9 are mainly secreted by tumor cells and stromal cells in the form of zymogens.
What is MMP-2 test?
MMP-2 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-2; monoclonal antibody is the capture antibody and signal polyclonal antibody is conjugated with horse-raddish peroxidase (HRP).
What is MMP made of?
The basic structure of MMPs (Collagenases, Stromelysins and other MMPs) is composed of a signal peptide (Pre), a propeptide domain (Pro), a catalytic domain (Cat) and a hinge region (H) and C-terminal, hemopexin-like domain (HPX). Gelatinases contain three fibronectin type II repeats in the Cat (FN).
What is the function of TIMPs?
TIMPs have various biological activities including the modulation of cell proliferation, cell migration and invasion, anti-angiogenesis, anti- and pro-apoptosis and synaptic plasticity.
What is mmp3 enzyme?
MMP-3 enzyme is also known as Stromelysin-1or as Transin-1 which hydrolyzes natural collagen at physiological pH and temperature. It dissolves the intervertebral nucleus pulposus and annulus fibrosus of Herniated Lumbar Intervertebral Disk .
What is MMPI in psychology?
The Minnesota Multiphasic Personality Inventory (MMPI) is the most widely used and researched clinical assessment tool used by mental health professionals to help diagnose mental health disorders.
Does MMPI diagnose personality disorders?
The MMPI-2 is a self-report inventory with 567 true-false questions about yourself. Your answers help mental health professionals determine whether you have symptoms of a mental illness or personality disorder. Some questions are designed to reveal how you feel about taking the test.
What is the function of MMPs?
In summary, MMPs are multifunctional proteases that: 1) proteolyse ECM components with subsequent release of bioactive fragments and proteins; 2) participate in membrane shedding; 3) play an important role in chemokine processing; and 4) alter the activity status of other proteases.
How many MMPs are there?
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.
