Live-cell visualisation of chromatin for the study of radiation-induced chromosome aberrations

, 2011
This thesis was submitted for the degree of Master of Philosophy and awarded by Brunel University.Chromosomes can be visualised during the metaphase stage of the cell cycle however, there are various limitations associated with the visualisation of ...

Mechanism of chromatin reassembly at the yeast PHO5 promoter upon repression [PDF]

, 2007
The goal of this study has been to elucidate the mechanisms responsible for rebuilding nucleosomes at the PHO5 promoter upon rerepression. In this work, I could unambiguously show that histones are incorporated at the PHO5 promoter upon repression ...

Candida albicans repetitive elements display epigenetic diversity and plasticity [PDF]

, 2016
Transcriptionally silent heterochromatin is associated with repetitive DNA. It is poorly understood whether and how heterochromatin differs between different organisms and whether its structure can be remodelled in response to environmental signals. Here,

Effect of terahertz irradiation on DNA damage repair in living cells

FEBS Open Bio, EarlyView.
We investigated the effect of terahertz (THz) wave irradiation on DNA double‐strand break (DSB) repair in living cells. We found that THz irradiation enhanced DSB repair at specific frequencies, whereas heat treatment inhibited it, indicating that this effect is nonthermal and frequency‐specific.

Human cytomegalovirus IE1 protein alters the higher-order chromatin structure by targeting the acidic patch of the nucleosome

eLife, 2016
Human cytomegalovirus (hCMV) immediate early 1 (IE1) protein associates with condensed chromatin of the host cell during mitosis. We have determined the structure of the chromatin-tethering domain (CTD) of IE1 bound to the nucleosome core particle, and ...

Compositional and structural analysis of selected chromosomal domains from Saccharomyces cerevisiae

, 2012
In eukaryotic genomes, chromatin is the template of all nuclear processes including transcription, recombination and replication. Besides the wrapping of DNA in nucleosome core particles, eukaryotic chromatin is associated, interpreted and modified by ...

Aging Is a Key Driver for Adult Acute Myeloid Leukemia

Aging and Cancer, EarlyView.
Acute myeloid leukemia (AML) is a classical age‐related hematologic malignancy, and a key driver of AML is aging, which profoundly regulates intrinsic factors such as genomic instability, epigenetic reprogramming, and metabolic dysregulation, and alters bone marrow microenvironment.

Initial Genomics of the Human Nucleolus [PDF]

, 2010
We report for the first time the genomics of a nuclear compartment of the eukaryotic cell. 454 sequencing and microarray analysis revealed the pattern of nucleolus-associated chromatin domains (NADs) in the linear human genome and identified different ...

Mutant NPM1 in Acute Myeloid Leukemia Initiation and Maintenance

Aging and Cancer, EarlyView.
NPM1 mutations drive acute myeloid leukemia by acting as neomorphic transcriptional regulators that cooperate with Menin–MLL and XPO1 to sustain HOX/MEIS1 expression and block differentiation. Targeting these mutant‐specific transcriptional dependencies provides a rational therapeutic strategy for NPM1‐mutated AML.

Transcription factor complex formation and chromatin fine structure alterations at the murine c-fms (CSF-1 receptor) locus during maturation of myeloid precursor cells [PDF]

, 2002
Expression of the gene for the macrophage colony stimulating factor receptor (CSF-1R), c-fms, has been viewed as a hallmark of the commitment of multipotent precursor cells to macrophages.
