TypeGene ModificationChromosome rearrangementProtein expressionProtein Function
tumoral       loss of function
by methylation in uterus breast, colon, brain carcinomas
tumoral       loss of function
in renal clear cell carcinoma with poor prognosis
constitutional     --low  
in heart failure
tumoral     --low  
in uveal melanoma with metastases
constitutional     --over  
increased in the renal arteries and proximal tubules of subjects with diabetic nephropathy or chronic allograft nephropathy
constitutional     --low  
is reduced in atherosclerotic plaques from subjects with type 2 diabetes and increased by SIRT1
constitutional     --low  
during preadipocyte differentiation, the Sp1-dependent decrease in TIMP3 expression is required for the successful implementation of the adipocyte differentiation program
tumoral        
silenced by promoter methylation in a consistent fraction of Papillary thyroid carcinoma
constitutional     --low  
increases inflammation and polarizes macrophages towards a more inflammatory phenotype resulting in increased atherosclerosis
constitutional     --over  
TIMP3 mRNA expression increases and TIMP3 protein is in the appropriate cellular layers to regulate proteolytic remodeling as the follicle progresses toward ovulation
constitutional        
induces choroidal neovascularization by moderating the polarization of macrophages in age-related macular degeneration
Susceptibility to age-related macular degeneration
Variant & Polymorphism SNP , other
  • SNP may contribute to individual differences in breast cancer susceptibilty and survival
  • S156C mutation results in an abnormal localization of protein and increases angiogenesis
  • association of variants with age-related macular degeneration
  • expression level of TIMP3 was significantly associated with AMD pathology
  • Candidate gene
    Marker
  • plasma TIMP3 is a potential biomarker for predicting the tumor stage and T status in patients with oral squamous cell carcinoma (OSCC)
  • positive correlation between TIMP-3 promoter methylation and gastric cancer risk and indicated that TIMP-3 promoter methylation may be used as a molecular marker for gastric cancer
  • Therapy target
    SystemTypeDisorderPubmed
    cancerhead and neck 
    promoter methylation of TIMP3 (and CDH1) predicts better outcome in head and neck squamous cell carcinoma treated by radiotherapy only
    cardiovascular  
    could serve as a therapeutic approach in limiting abdominal aortic aneurysm development or expansion
    cancerbone 
    TIMP3 is a new target for inhibition of progression and chemotherapeutic resistance
    ANIMAL & CELL MODELS
  • iron overload in Timp3-/- mice showed twofold higher iron accumulation in the liver compared with WT mice because of constituently lower levels of ferroportin
