Description

Introduction to MMP12 Antibody

MMP12 antibodies are immunological tools designed to detect and quantify matrix metalloproteinase-12 (MMP12), a protease involved in extracellular matrix remodeling, immune modulation, and disease progression. These antibodies are critical for research and diagnostic applications, including Western blot (WB), immunohistochemistry (IHC), and immunofluorescence (IF) .

Biological Roles of MMP12

MMP12, also known as macrophage metalloelastase, is implicated in both physiological and pathological processes:

  • Asthma: MMP12 supports pulmonary B cell follicle formation and local antibody responses. Its absence in Mmp12−/− mice reduces germinal center B cells and allergen-specific IgE/IgA levels, impairing adaptive immunity .

  • Cancer: Overexpression in lung squamous cell carcinoma (LUSC) correlates with poor prognosis and immune cell infiltration. MMP12 facilitates tumor growth, invasion, and metastasis .

  • Vascular Remodeling: Cleaves N-cadherin to activate β-catenin signaling, promoting vascular smooth muscle proliferation .

Target Background

Function
MMP12, also known as macrophage elastase, is a matrix metalloproteinase that plays a role in tissue injury and remodeling. It exhibits significant elastolytic activity, meaning it can break down elastin, a key component of connective tissue. MMP12 is known to accept both large and small amino acids at the P1' site, but it prefers leucine. At the P1 site, it shows a preference for aromatic or hydrophobic residues, with small hydrophobic residues (ideally alanine) occupying the P3 position.

Gene References and Functions

  1. A study conducted on a Bulgarian population investigated the association between the MMP12 -82 A>G promoter single nucleotide polymorphism (SNP) and bronchial asthma. The results suggest that the variant G allele of this polymorphism may be protective against the development of bronchial asthma. PMID: 29390099
  2. Research indicates that MMP-12 could potentially serve as a target for the development of novel therapeutic agents for esophageal squamous cell carcinoma. PMID: 29033183
  3. Studies have revealed an association between MMP-12 (-82A/G) polymorphisms and both the risk of obesity and its severity. PMID: 29317790
  4. A meta-analysis has demonstrated a significant association between the MMP-12 (-1082 A/G) gene polymorphism and the risk of ischemic stroke (OR 2.55; 95% CI 1.75 to 3.71). PMID: 29906531
  5. Downregulation of MMP12 through increased oxygen concentration has been observed to enable temporal expression control of MMP12. This process involves several mechanisms, including HIF-1alpha. These findings suggest a role for MMP12 in trophoblast invasion during the first trimester of pregnancy. PMID: 28990117
  6. Research has demonstrated that hypoxia activates a HIF-KDM3A-MMP12 signaling cascade, promoting trophoblast invasion and the remodeling of uterine spiral arteries. PMID: 27807143
  7. Current evidence suggests that the MMP12 rs652438 polymorphism, but not MMP12 rs2276109, may influence the risk of Parkinson's disease. PMID: 28655442
  8. M4 macrophages have been identified as a potential source for HDAC9 and MMP12 expression in advanced human carotid plaques. PMID: 28343758
  9. Elevated MMP12 levels have been observed in the gingival tissue of patients with periodontitis. MMP12-producing monocyte-derived cells exhibit reduced CD200R surface levels. The production of MMP12 by these cells is induced by CSF2, and treatment with a CD200R ligand has been shown to reduce CSF2-induced MMP12 production. This novel association between the CD200/CD200R pathway and MMP12 production by monocyte-derived cells may play a crucial role in the progression of periodontitis. PMID: 29101312
  10. In the Bulgarian population, the G allele of the MMP12 -82 A > G promoter polymorphism has been identified as a protective factor for chronic obstructive pulmonary disease (COPD). PMID: 28692348
  11. Studies have shown that MMP12 facilitates platelet aggregation, adhesion, and alpha granule secretion induced by type I collagen.

  12. Research has indicated that Pseudomonas aeruginosa infection induces the expression of matrix metalloproteinases.
