Special Issue Information

Dear Colleagues,

In organisms, disorder and abnormal transcription in the regulation of genes often results in diseases and phenotypic defects. Gene transcriptions are complex multi-level processes controlled by cis- and trans-regulatory elements (e.g., promoters, enhancers, insulators, silencers, poly (dA:dT) tracts and other regulatory elements), as well as regulatory RNAs such as miRNAs, lncRNAs and circRNAs. However, current knowledge of these regulatory elements and RNAs is still limited. Thanks to the success of the ENCODE, FANTOM and GTEX Projects, we know that most DNA is not “junk” and has actual regulatory functions. Using novel biotechnologies such as RNA sequencing, single-cell multi-omics, ChIA-PET and Hi-C chromosome conformation capture, more regulatory elements and RNAs are bioinformatically characterized for transcribed regions and transcript isoforms, which are recognized by RNA-binding proteins, DNA-binding proteins, transcription factor-binding regions that harbour specific histone modifications, DNA methylations, open chromatins, and 3D chromatin interactions in different cellular types and tissues.

It is important to note the advances in, approaches to and pipelines for the bioinformatic analysis of gene transcription regulation to reveal more regulatory elements and regulatory RNAs. We are pleased to invite authors to submit manuscripts on the regulatory transcriptions of genes with bioinformatic analysis on genomics, epigenomics or transcriptomics, as well as single-cell multi-omics, in different cellular types and tissues. In this Special Issue, original articles and reviews on bioinformatic research or tools are welcome. Research areas may include (but are not limited to): RNA-binding proteins, DNA-binding proteins, transcription factor-binding regions, specific histone modifications, DNA methylations, open chromatin and 3D chromatin interactions, and regulatory RNAs.

 

We look forward to receiving your contributions.

Cell autonomous circadian oscillation is present in central and various peripheral tissues. The intrinsic tissue clock and various extrinsic cues drive gene expression rhythms. Transcription regulation is thought to be the main driving force for gene rhythms. However, how transcription rhythms arise remains to be fully characterized due to the fact that transcription is regulated at multiple steps. In particular, Pol II recruitment, pause release, and premature transcription termination are critical regulatory steps that determine the status of Pol II pausing and transcription output near the transcription start site (TSS) of the promoter. Recently, we showed that Pol II pausing exhibits genome-wide changes during daily transcription in mouse liver. In this article, we review historical as well as recent findings on the regulation of transcription rhythms by the circadian clock and other transcription factors, and the potential limitations of those results in explaining rhythmic transcription at the TSS. We then discuss our results on the genome-wide characteristics of daily changes in Pol II pausing, the possible regulatory mechanisms involved, and their relevance to future research on circadian transcription regulation.
