Description
Matrix metallopeptidase 9 (MMP-9) is an enzyme encoded by the MMP9 gene. This protein; which is produced by normal alveolar macrophages and granulocytes; can be activated by 4-aminophenylmercuric acetate and phorbol ester and up-regulated by ARHGEF4; SPATA13 and APC via the JNK signaling pathway in colorectal tumor cells. MMP-9 is involved in the breakdown of extracellular matrix in normal physiological processes; such as embryonic development; reproduction; angiogenesis; bone development; wound healing; cell migration; learning and memory; as well as in pathological processes; such as arthritis; intracerebral hemorrhage; and metastasis
