objective(s): the purpose of this study was to conduct a meta-analysis on human micrornas (mirnas) expression data of endometriosis tissue profiles versus those of normal controls and to identify novel putative diagnostic markers. materials andmethods: pubmed, embase, web of science, ovid medline were used to search for endometriosis mirna expression profiling studies of endometriosis. the mirn...
The so-called amyloid hypothesis, that the accumulation and deposition of oligomeric or fibrillar amyloid β (Aβ) peptide is the primary cause of Alzheimer's disease (AD), has been the mainstream concept underlying AD research for over 20 years. However, all attempts to develop Aβ-targeting drugs to treat AD have ended in failure. Here, we review recent findings indicating that the main factor u...
We investigate the possibility that microRNA can act as an oncogene or tumor suppressor gene. Experimentally verified microRNA target genes information (TarBase) are integrated with microRNA and mRNA expression data (NCI-60) to study this hypothesis, in which the Pearson correlation and Spearman rank coefficients are used to quantify these relations for nine cancer types. Correlation coefficien...
In the post-human genomic era, more and more other genomes have been sequenced. Comparative genomic analysis gives us an opportunity to find out the similarities and differences among different organisms. Moreover, comparative analysis of metabolic pathway can give us important information on their evolution and potential pharmacological targets. In this study, we propose a cross-species pathwa...
From Alois Alzheimer's description of Auguste D.'s brain in 1907 to George Glenner's biochemical dissection of beta-amyloid in 1984, the "amyloid hypothesis" of Alzheimer's disease has continued to gain support over the past two decades, particularly from genetic studies. Here we assess the amyloid hypothesis based on both known and putative Alzheimer's disease genes.
In this paper, we present KEGGscape a pathway data integration and visualization app for Cytoscape ( http://apps.cytoscape.org/apps/keggscape). KEGG is a comprehensive public biological database that contains large collection of human curated pathways. KEGGscape utilizes the database to reproduce the corresponding hand-drawn pathway diagrams with as much detail as possible in Cytoscape. Further...
A new database system named KEGG is being organised to computerize functional aspects of genes and genomes in terms of the binary relations of interacting molecules or genes. We are currently working on the metabolic pathway database that is composed of three interconnected sections: genes, molecules, and pathways, which are also linked to a number of existing databases through our DBGET retrie...
MOTIVATION Pathway association analysis has made great achievements in elucidating the genetic basis of human complex diseases. However, current pathway association analysis approaches fail to consider tissue-specificity. RESULTS We developed a tissue-specific pathway interaction enrichment analysis algorithm (TPIEA). TPIEA was applied to two large Caucasian and Chinese genome-wide associatio...
