Mammalian housekeeping genes evolve more slowly than tissue-specific genes.
Do housekeeping genes, which are turned on most of the time in almost every tissue, evolve more slowly than genes that are turned on only at specific developmental times or tissues? Recent large-scale gene expression studies enable us to have a better definition of housekeeping genes and to address the above question in detail. In this study, we examined 1581 human-mouse orthologous gene pairs ...
متن کاملTissue-specific regulation of mouse MicroRNA genes in endoderm-derived tissues
MicroRNAs fine-tune the activity of hundreds of protein-coding genes. The identification of tissue-specific microRNAs and their promoters has been constrained by the limited sensitivity of prior microRNA quantification methods. Here, we determine the entire microRNAome of three endoderm-derived tissues, liver, jejunum and pancreas, using ultra-high throughput sequencing. Although many microRNA ...
متن کاملTISA: tissue-specific alternative splicing in human and mouse genes.
Alternative splicing (AS) is a mechanism by which multiple transcripts are produced from a single gene and is thought to be an important mechanism for tissue-specific expression of transcript isoforms. Here, we report a novel graphing method for transcript reconstruction and statistical prediction of tissue-specific AS. We applied three selection steps to generate the splice graph and predict t...
متن کاملPartitioning the Human Transcriptome Using HKera, a Novel Classifier of Housekeeping and Tissue-Specific Genes
High-throughput transcriptomic experiments have made it possible to classify genes that are ubiquitously expressed as housekeeping (HK) genes and those expressed only in selective tissues as tissue-specific (TS) genes. Although partitioning a transcriptome into HK and TS genes is conceptually problematic owing to the lack of precise definitions and gene expression profile criteria for the two, ...
متن کاملTissue-specific disallowance of housekeeping genes: the other face of cell differentiation.
We report on a hitherto poorly characterized class of genes that are expressed in all tissues, except in one. Often, these genes have been classified as housekeeping genes, based on their nearly ubiquitous expression. However, the specific repression in one tissue defines a special class of "disallowed genes." In this paper, we used the intersection-union test to screen for such genes in a mult...
