    • 功能:
      Type IV collagen is the major structural component of glomerular basement membranes (GBM), forming a 'chicken-wire' meshwork together with laminins, proteoglycans and entactin/nidogen.; Canstatin, a cleavage product corresponding to the collagen alpha 2(IV) NC1 domain, possesses both anti-angiogenic and anti-tumor cell activity. It inhibits proliferation and migration of endothelial cells, reduces mitochondrial membrane potential, and induces apoptosis. Specifically induces Fas-dependent apoptosis and activates procaspase-8 and -9 activity. Ligand for alphavbeta3 and alphavbeta5 integrins.
    • 基因功能参考文献:
      1. Herein, we describe a large family of first-degree relatives affected by a novel heterozygous variant in COL4A2 (c.3490G.A). PMID: 28542708
      2. Data showed that Col4A2 can restrain triple-negative breast cancer (TNBC) cell lines MDA-MB-231 and MDA-MB-468 proliferation, migration, cell cycle, and ultimately lead to apoptosis. The data indicated that Col4A2 was significantly correlated with the proliferation and invasive potential of TNBC. PMID: 27906681
      3. In this study, the inhibitory effect of recombinant canstatin on tumour growth was investigated using a gastric cancer xenograft model. PMID: 27919040
      4. These results of this study provide evidence that the mutation of COL4A2 is associated with lacunar ischemic stroke and deep intracerebral hemorrhage. PMID: 28954878
      5. COL4A2 expression is significantly upregulated in human masticatory mucosa during wound healing PMID: 28005267
      6. These results indicate that the CHD-related genetic variant at the COL4A2 locus affects COL4A2/COL4A1 expression, smooth muscle cells survival, and atherosclerotic plaque stability, providing a mechanistic explanation for the association between the genetic variant and CHD risk. PMID: 27389912
      7. Expression of miR-26a and miR-29a was significantly down regulated in leukoplakia and cancer tissues but up regulated in lichen planus tissues. Expression of target genes such as, ADAMTS7, ATP1B1, COL4A2, CPEB3, CDK6, DNMT3a and PI3KR1 was significantly down regulated in at least two of three disease types with respect to normal tissues. PMID: 27515006
      8. identified a novel COL4A2 (c.2399G>A, p.G800E, CCDS41907.1) mutation in an autosomal dominant family with porencephaly and ocular abnormalities PMID: 26708157
      9. No significant change in canstatin levels was observed between normotensive and pre-eclampsia patients. PMID: 26343951
      10. Reduction of COL4A2 expression by RNAI-mediated knockdown induces cell death. Finally, elevated Notch3 expression levels correlate with higher COL4A2 expression in human ovarian tumor specimens PMID: 25169943
      11. An association was found between common variation in the COL4A2 gene and sporadic cerebral small vessel disease. PMID: 25653287
      12. Interleukin-1-induced changes in the glioblastoma secretome suggest its role in tumor progression. PMID: 24503185
      13. dominant COL4A2 mutations are a novel major risk factor for familial cerebrovascular disease, including porencephaly and small-vessel disease with reduced penetrance and variable phenotype, which might also be modified by other contributing factors. PMID: 22333902
      14. this study confirmed that abnormalities of the alpha1alpha1alpha2 heterotrimers of type IV collagen cause porencephaly and stresses the importance of screening for COL4A2 as well as for COL4A1. PMID: 22209246
      15. COL4A2 was overexpressed in the ER-negative breast cancer group. PMID: 20805453
      16. an imbalance of glomerular alpha2(IV) and alpha5(IV) chain expression occurred in IgA nephropathy PMID: 12021518
      17. Data show that the NC1 but not 7S domain is essential for chain association and initiation of triple helix formation in human collagen alpha2(IV) . PMID: 15522229
      18. alpha2(IV)NC1 domain has a role in regulating tumor cell behavior PMID: 15743801
      19. Comparison of alpha5(IV) with alpha2(IV) expression in Alport patients is simple and eliminates technical artifacts. PMID: 17554254
      20. support a crucial role for angiogenesis inhibitors in shifting the fate of radiation-induced HIF-1alpha activity from hypoxia-induced tumor radioresistance to hypoxia-induced tumor apoptosis PMID: 17557121
      21. The co-detection of alpha5 and alpha2 chains of collagen IV in frozen skin biopsies is therefore proposed as a simple technique to diagnose Alport syndrome. PMID: 18706356
      22. E1B-55kD-deleted oncolytic adenovirus armed with canstatin gene yields an enhanced anti-tumor efficacy on pancreatic cancer. PMID: 19481338
