BackgroundMost eukaryotic protein‐coding genes exhibit alternative cleavage and polyadenylation (APA), resulting in mRNA isoforms with different 3′ untranslated regions (3′ UTRs). Studies have shown that brain cells tend to express long 3′ UTR isoforms using distal cleavage and polyadenylation sites (PASs).Methods...... hiện toàn bộ

Chromatin immunoprecipitation coupled with massive parallel sequencing (ChIP‐seq) is a powerful technology to identify the genome‐wide locations of DNA binding proteins such as transcription factors or modified histones. As more and more experimental laboratories are adopting ChIP‐seq to unravel the transcriptional and epigenetic regulatory mechanisms, computational analyses of ChIP‐seq al...... hiện toàn bộ
The principles and molecular mechanisms underlying biological pattern formation are difficult to elucidate in most cases due to the overwhelming physiologic complexity associated with the natural context. The understanding of a particular mechanism, not to speak of underlying universal principles, is difficult due to the diversity and uncertainty of the biological systems. Although current genetic...... hiện toàn bộ
The Cistrome Data Browser (DB) at the website (cistrome.org/db) provides about 56,000 published human and mouse ChIP‐seq, DNase‐seq, and ATAC‐seq chromatin profiles, which we have processed using uniform analysis and quality control pipelines. The Cistrome DB Toolkit at the website ( hiện toàn bộ
BackgroundMicroRNAs (miRNAs) are a significant type of non‐coding RNAs, which usually were encoded by endogenous genes with about ~22 nt nucleotides. Accumulating biological experiments have shown that miRNAs have close associations with various human diseases. Although traditional experimental methods achieve great successes in miRNA‐disease interaction ...... hiện toàn bộ

BackgroundSymmetry of biological structures can be thought as the repetition of their parts in different positions and orientations. Asymmetry analyses, therefore, focuses on identifying and measuring the location and extent of symmetry departures in such structures. In the context of geometric morphometrics, a key step when studying morphological variati...... hiện toàn bộ
BackgroundPrecision medicine approach holds great promise to tailored diagnosis, treatment and prevention. Individuals can be vastly different in their genomic information and genetic mechanisms hence having unique transcriptomic signatures. The development of precision medicine has
demanded moving beyond DNA sequencing (DNA‐Seq) to much more pointed RNA‐...... hiện toàn bộ
BackgroundA main goal of metagenomics is taxonomic characterization of microbial communities. Although sequence comparison has been the main method for the taxonomic classification, there is not a clear agreement on similarity calculation and similarity thresholds, especially at higher taxonomic levels such as phylum and class. Thus taxonomic classificati...... hiện toàn bộ
