COL4A mutations comprise a frequent cause of Familial microscopic hematuria.
Title: Frequent COL4 mutations in familial microhematuria accompanied by later-onset Alport nephropathy due to focal segmental glomerulosclerosis.
These findings suggested that artesunate attenuates alveolitis and pulmonary fibrosis by regulating expression of collagen-IV, TIMP-1 and 2, as well as MMP-2 and -9, to reduce ECM accumulation.
Title: Artesunate modulates expression of matrix metalloproteinases and their inhibitors as well as collagen-IV to attenuate pulmonary fibrosis in rats.
Data show that collagen type III (Col3), collagen type IV (Col4) and p38 mitogen-activated protein kinase (p38 MAPK) are up-regulated in models of diabetic nephropathy.
Title: [Down-regulation of p38 MAPK and collagen by 1, 25-(OH)2-VD3 in rat models of diabetic nephropathy].
Glomerular collagen alpha3(IV) protein was higher and more intense in immunofluorescence staining according to diabetic durations.
Title: Regulation of type IV collagen alpha chains of glomerular epithelial cells in diabetic conditions.
Segregation of experimental autoimmune glomerulonephritis as a complex genetic trait and exclusion of Col4a3 as a candidate gene. No significant linkage was detected in the region of rat chromosome 9 where Col4a3 is localized.
Title: Segregation of experimental autoimmune glomerulonephritis as a complex genetic trait and exclusion of Col4a3 as a candidate gene.
only few residues in the nephritogenic T-cell epitope pCol(28-40) were critical; pCol(28-40) is a potential nephritogenic T-cell epitope in Goodpasture's syndrome.
Title: Characterization of the T-cell epitope that causes anti-GBM glomerulonephritis.
Downregulation of alpha3(IV) and enhancement of the matrix metalloproteinase-2 activity in the glomeruli may contribute to the glomerular damage by altering the glomerular basement membrane components.
Title: Altered expression of matrix-related molecules in the development of chronic Thy1.1 nephritis.
The T cell epitope pCol(28-40) of noncollagen domain 1 of collagen type IV alpha 3 chain not only uniformly induces severe glomerulonephritis but also elicits anti-GBM antibodies in 76% of immunized rats after prominent glomerular injury in a rat model.
Title: A self T cell epitope induces autoantibody response: mechanism for production of antibodies to diverse glomerular basement membrane antigens.
results suggest the activated MMP-9 induced by TNFalpha cleaves the existing collagen network in the extracellular matrix, perturbing the Sertoli cell TJ-barrier; this creates a negative feedback causing TNFalpha to induce collagen alpha3(IV) and TIMP-1
Title: The interplay of collagen IV, tumor necrosis factor-alpha, gelatinase B (matrix metalloprotease-9), and tissue inhibitor of metalloproteases-1 in the basal lamina regulates Sertoli cell-tight junction dynamics in the rat testis.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
