Studies of gene expression in experimental cerebral ischaemia models can contribute to understanding the pathophysiology of brain ischaemia and to identifying prognostic markers and potential therapeutic targets. The normalization of relative qRT-PCR data using a suitable reference gene is a crucial prerequisite for obtaining reliable conclusions. No(More)
OBJECTIVE The IGF-II receptor gene (IGFIIR) is located at chromosome 6q26, a region that harbors a genetic marker linked to insulin-resistant traits in Mexican-Americans. In the present study conducted in Spaniards, we tested a common polymorphism in IGFIIR for association with type 2 diabetes and insulin-resistant traits. DESIGN Case-control association(More)
The innate immune system can immediately respond to microorganism intrusion by helping to prevent further invasion. Bactericidal/permeability-increasing protein (BPI) is a major constituent of neutrophils that possesses anti-inflammatory properties. Inflammation is increasingly recognized as a component of the metabolic syndrome. We hypothesized that the(More)
Despite the large number of molecules reported as being over-expressed after ischaemia, little is known regarding their regulation. miRNAs are potent post-transcriptional regulators of gene expression, and reports have shown differentially miRNA expression in response to focal cerebral ischaemia. The present study analysed miRNA expression from acute to(More)
The present study aims to identify transcription factors (TFs) contributing to angiogenesis, a mechanism involved in giving plasticity to the brain, as potential therapeutic targets after cerebral ischemia. The promoter sequences from candidate genes involved in angiogenesis were submitted to a comparative analysis by bioinformatics software. High-mobility(More)
Leucine-rich repeat in Flightless-1 interaction protein 1 (Lrrfip1) is an up-regulated protein after cerebral ischemia whose precise role in the brain both in healthy and ischemic conditions is unclear. Different Lrrfip1 isoforms with distinct roles have been reported in human and mouse species. The present study aimed to analyze the Lrrfip1 transcriptional(More)
Hemorrhagic transformation (HT) of cerebral infarction is a common and serious occurrence following acute ischemic stroke. The expression of survivin, a member of the inhibitor of apoptosis protein family, has been shown to increase after cerebral ischemia. This protein has been mainly located at the microvasculature within the infarcted and peri-infarcted(More)
Brain plasticity provides a mechanism to compensate for lesions produced as a result of stroke. The present study aims to identify new transcription factors (TFs) following focal cerebral ischaemia in rat as potential therapeutic targets. A transient focal cerebral ischaemia model was used for TF-binding activity and TF–TF interaction profile analysis. A(More)
Conventional C18 silica columns have proven to be useful for the analysis of amino acids (AA) from protein hydrolysates but undesirable peak overlapping is usually found when analyzing body fluids given that a large number of AAs are present in the samples. As an alternative to silica packings, an ethyl-bridged packing for reversed-phase liquid(More)
