Abstract:
ABSTRACT Short repetitive sequences are common in the human genome, and many fall within transcription units. We have previously shown that transcription through CAG repeat tracts destabilizes them in a way that depends on transcription-coupled nucleotide excision repair and mismatch repair. Recent observations that antisense transcription accompanies sense transcription in many human genes led us to test the effects of antisense transcription on triplet repeat instability in human cells. Here, we report that simultaneous sense and antisense transcription (convergent transcription) initiated f

Abstract:
ABSTRACT Transcriptional interference is the influence, generally suppressive, of one active transcriptional unit on another unit linked in cis. Its wide occurrence in experimental systems suggests that it may also influence transcription in many loci, but little is known about its precise nature or underlying mechanisms. Here we report a study of the interaction of two nearly identical transcription units juxtaposed in various arrangements. Each reporter gene in the constructs has its own promoter and enhancer and a strong polyadenylation signal. We used recombinase-mediated cassette exchange

AbstractDinoflagellate chromosomes represent a unique evolutionary experiment, as they exist in a permanently condensed, liquid crystalline state; are not packaged by histones; and contain genes organized into tandem gene arrays, with minimal transcriptional regulation. We analyze the three-dimensional genome of Breviolum minutum, and find large topological domains (dinoflagellate topologically associating domains, which we term ‘dinoTADs’) without chromatin loops, which are demarcated by convergent gene array boundaries.

Abstract DNA supercoiling acts as a global transcriptional regulator in bacteria, that plays an important role in adapting their expression programme to environmental changes, but for which no quantitative or even qualitative regulatory model is available. Here, we focus on spatial supercoiling heterogeneities caused by the transcription process itself, which strongly contribute to this regulation mode. We propose a new mechanistic modeling of the transcription-supercoiling dynamical coupling along a genome, which allows simulating and quantitatively reproducing in vitro and in vivo transcript

Abstract:
Genomic DNA is organised in complex spatial arrangements, and a given stretch of DNA may encode more than one gene. In some cases one gene may be entirely contained within a region of the DNA already occupied by another larger gene. The presence of these nested genes, often situated in introns and in the opposite orientation, poses important implications with regards to gene expression, function and regulation. A consequence of the nested gene arrangement is convergent transcription, occurring when two promoters on opposite DNA strands are active. Elucidating the mechanics of multiple interact

With recent advances in sequencing and mapping of genomes, the occurrence of overlapping and nested transcription units is more common than previously thought in both eukaryotes and prokaryotes. The interleaved genome model means that transcriptional interference by collisions between concurrently transcribing RNA polymerases is more likely than ever before.

Abstract:
DNA damage is an ongoing threat to both the ability of the cell to faithfully transmit genetic information to its offspring as well as to its own survival. In order to maintain genomic integrity, eukaryotes have developed a highly conserved mechanism to detect, signal and repair damage in DNA, known as the DNA damage response (DDR). In fission yeast the two DDR pathways converge at the regulation of single transcriptional factor complex (MBF) resulting in opposite directions. We have shown that when the DNA-synthesis checkpoint is activated, Max1 is phosphorylated by Cds1 resulting in the abro

BCL6 is a zinc finger transcriptional repressor, which is highly expressed in germinal centre B-cells, and is essential for germinal centre formation and T-dependent antibody responses. Deregulated BCL6 expression is associated with certain non- Hodgkin’s lymphomas. High expression is observed in breast cancer. Tight lineage and temporal regulation of BCL6 is, therefore, required for normal immunity and abnormal regulation occurs in cancer. Regulatory mechanisms have been analysed in two settings. Firstly, BCL6 is strongly induced by the tyrosine kinase inhibitor, Imatinib, in chronic myeloid

Generation of cardiac asymmetry is crucial to ensure the proper form and consequent function of the heart and thus is a highly regulated process. Molecular signals originate long before morphological asymmetry and therefore can direct it; a complex regulatory network has been characterized which invariably converges on the Tgf-β‎ signalling molecule Nodal and its downstream target, the homeobox transcription factor Pitx2.

Although representing only a very small volume of the heart, the conduction system plays a crucial role in the appearance of cardiac arrhythmias. The cells forming the conduction system are derived from the same cardiac progenitors as the working cardiomyocytes, and the choice between these
