Genetic risk factors for ischaemic stroke and its subtypes (the METASTROKE coll...

Various genome-wide association studies (GWAS) have been done in ischaemic stroke, identifying a few loci associated with the disease, but sample sizes have been 3500 cases or less. We established the METASTROKE collaboration with the aim of validating associations from previous GWAS and identifying novel genetic associations through meta-analysis of GWAS datasets for ischaemic stroke and its subtypes.

A genome-wide association study using a DNA pooling strategy identifies BBS9 an...

Stroke is a major cause of morbidity in developed countries and therefore finding adequate treatments to promote patient’s recovery is a priority task, requiring the elucidation of the molecular pathways influencing brain recovery. Few studies, however, have assessed the role of genes in stroke outcome. This study describes a pilot genome-wide association study (GWAS) to identify genetic factors contributing to...

Association of a genetic variant in the ALOX5AP with higher risk of ischemic st...

Variants in the 5-lipoxygenase-activating protein (ALOX5AP) and phosphodiesterase 4D (PDE4D) genes have first been associated with ischemic stroke (IS) through whole-genome linkage screens. However, association studies obtained conflicting results. We aimed to investigate the contribution of selected single nucleotide polymorphisms (SNPs) in these genes for the first time in a large Iberian population.

Variants of the Matrix Metalloproteinase-2 but not the Matrix Metalloproteinase...

Multiple lines of evidence suggest that genetic factors contribute to stroke recovery. The matrix metalloproteinases -2 (MMP-2) and -9 (MMP-9) are modulators of extracellular matrix components, with important regulatory functions in the Central Nervous System (CNS). Shortly after stroke, MMP-2 and MMP-9 have mainly damaging effects for brain tissue. However, MMPs also have a beneficial activity in angiogenesis ...

Detection of caliciviruses associated with acute infantile gastroenteritis in S...

Acute gastroenteritis caused by viruses is one of the leading causes of infantile morbidity. The aim of the present study was to investigate the presence of human caliciviruses of the genera norovirus and sapovirus in children up to 3 years of age with acute gastroenteritis from low-income communities in the city of Salvador, Brazil. This study is an extension of previous work carried out to establish the profi...

Mitochondrial haplogroup H1 is protective for ischemic stroke in Portuguese pat...

The genetic contribution to stroke is well established but it has proven difficult to identify the genes and the disease-associated alleles mediating this effect, possibly because only nuclear genes have been intensely investigated so far. Mitochondrial DNA (mtDNA) has been implicated in several disorders having stroke as one of its clinical manifestations. The aim of this case-control study was to assess the c...
