Collagen, type IV, alpha 1

COL4A1, collagen type IV alpha1, Arresten
This gene encodes the major type IV alpha collagen chain of basement membranes. Like the other members of the type IV collagen gene family, this gene is organized in a head-to-head conformation with another type IV collagen gene so that each gene pair shares a common promoter.

RESULTS: In EUA there were significant associations for CAC with SNPs in 9p21 (rs1333049, P = 2 × 10(-9); rs4977574, P = 4 × 10(-9)), COL4A1 (rs9515203, P = 9 × 10(-6)), and PHACTR1 (rs9349379, P = 4 × 10(-4)).
DNA hypermethylation of extracellular matrix-related genes in human periodontal fibroblasts induced by stimulation for a prolonged period with lipopolysaccharide derived from Porphyromonas gingivalis.
Abiko et al., Tōbetsu, Japan. In J Periodontal Res, 09 Dec 2015
Among these genes, hypermethylation of nine ECM-related genes, FANK1, COL4A1-A2, 12A1 and 15A1, LAMA5 and B1, MMP25, POMT1 and EMILIN3, induced a significantly downregulated expression of their mRNA.
Gain-of-function somatic mutations contribute to inflammation and blood vessel damage that lead to Alzheimer dementia: a hypothesis.
Marchesi, New Haven, United States. In Faseb J, 02 Dec 2015
Because heritable autosomal dominant mutations of NLRP3, APP, TREX1, NOTCH3, and Col4A1 are known to provoke inflammatory reactions and damage the brain in a wide variety of diseases, I propose that one or more low abundant, gain-of-function somatic mutations of the same 5 gene families damage the microvasculature of the brain that leads to dementia.
Anti-angiogenic collagen fragment arresten is increased from 16 weeks' gestation in pre-eclamptic plasma.
Keogh et al., Melbourne, Australia. In Placenta, Nov 2015
INTRODUCTION: Arresten and canstatin are endogenous anti-angiogenic factors derived from type IV collagen α-chains COL4A1 and COL4A2 respectively.
