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.

Increased decidual mRNA expression levels of candidate maternal pre-eclampsia susceptibility genes are associated with clinical severity.
Keogh et al., Melbourne, Australia. In Placenta, 28 Feb 2014
Through genome-wide linkage and genetic association studies in PE-affected families and large population samples, we previously identified the following as positional candidate maternal susceptibility genes for PE; ACVR1, INHA, INHBB, ERAP1, ERAP2, LNPEP, COL4A1 and COL4A2.
Fetal intracerebral hemorrhage and cataract: think COL4A1.
Bonneau et al., Angers, France. In J Perinatol, Jan 2014
The COL4A1 gene encodes the alpha1 chain of type IV collagen, a crucial component of nearly all basement membranes.
Prolyl-4-hydroxylase α subunit 2 promotes breast cancer progression and metastasis by regulating collagen deposition.
Xu et al., Lexington, United States. In Bmc Cancer, Dec 2013
RESULTS: Using gene co-expression analysis, we showed that P4HA2 was associated with expression of Col1A1, Col3A1, and Col4A1 during breast cancer development and progression.
Hereditary cerebral small vessel diseases: a review.
Dotti et al., Siena, Italy. In J Neurol Sci, 2012
Clinical features and diagnostic clues of these conditions, [cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy (CARASIL), COL4A1-related cerebral small vessel diseases, autosomal dominant retinal vasculopathy with cerebral leukodystrophy (AD-RVLC), and Fabry's disease] are here reviewed.

COL4A1 mutations in patients with sporadic late-onset intracerebral hemorrhage.
Gould et al., San Francisco, United States. In Ann Neurol, 2012
Our data support the hypothesis that increased intracellular accumulation of COL4A1, decreased extracellular COL4A1, or both, contribute to sporadic cerebrovascular disease and sporadic, nonfamilial, intracerebral hemorrhages

Camen et al., Craiova, Romania. In Rom J Morphol Embryol, 2011
analysis of collagen IV and MMP-9 expression in hypertrophic gingiva during orthodontic treatment

Stroke-related translational research.
Tournier-Lasserve et al., Boston, United States. In Arch Neurol, 2011
Herein, we highlight genome-wide association studies and genetic studies of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy, COL4A1 mutations, and cerebral cavernous malformations; advances in molecular biology and biomarkers; newer brain imaging research; and recovery from stroke emphasizing cell-based and other rehabilitative modalities.
