The brain responds to injury and infection by activating innate defense and tissue repair mechanisms. Working upon the hypothesis that the brain defense response involves common genes and pathways across diverse pathologies, we analysed global gene expression in brain from mouse models representing three major central nervous system disorders, cerebral stroke, multiple sclerosis and Alzheimer's disease...
The second codon of a transcript, besides encoding for an amino acid, is now known to also have multiple molecular functions and is involved in translation efficiency and protein turn-over and maturation processing. These multiple purposes therefore make the selection constraints on this codon's composition more complex. To examine the biological significance of various permutations of the second...
Transcription factors (TFs) are proteins that bind to specific promoter regions of their target genes and regulate gene transcription. Many of these factors have been found to influence flowering. Lycoris longituba exhibits a great deal of diversity in flower color and flower form, making it a suitable model for the study of floral development. We have identified 338 putative TFs from more than thirty...
The role of hyaluronan in cardiac growth has become evident, previously shown by increased myocardial levels of hyaluronan in a rat model of cardiac hypertrophy.To further investigate the role of hyaluronan and regulation of its synthesis in cardiac hypertrophy, quantitative measurements of myocardial hyaluronan concentration was correlated to gene transcription in hypertrophic cardiac tissue. Factor...
YPEL5 is a member of the YPEL gene family that is highly conserved in the eukaryotic species and apparently involved in a certain cell division-related function. In this study, we examined the functional and phylogenetic aspects of YPEL5 protein in more detail. During cell cycle, YPEL5 protein was detected at different subcellular localizations; at interphase, it was located in the nucleus and centrosome,...
Early studies suggested that most connexin genes share a relatively simple structure with a single intron of variable length interrupting the 5′ untranslated region (UTR). Here we report that zebrafish cx45.6 shows six isoforms of alternative 5′UTRs which are generated from multiple promoter usage and alternative pre-mRNA splicing. Interestingly, cx45.6 undergoes tandem alternative splicing, which...
While the methylation machinery of mammalian cells has been shown to be capable of both maintenance and de novo methylation at CpNpG sites, CpNpG methylation in the human genome has not been demonstrated. Here, we report the first observation of 5-methylcytosines in CpNpG triplets in the human genome. We identify the existence of CpNpG methylation in a number of genes which contain trinucleotide repeat...
