An atr‐dependent function for the ddx19 rna helicase in nuclear r‐loop metabolism
(EMBO, 2017-03-17)Coordination between transcription and replication is crucial in the maintenance of genome integrity. Disturbance of these processes leads to accumulation of aberrant DNA: RNA hybrids (R-loops) that, if unresolved, generate ... -
Analysis of the DNA damage response in model systems
(2014-07-24)The integrity of our DNA is constantly threatened by endogenous and exogenous sources of damage. In the absence of sufficient repair mechanisms, this damage can lead to mutations, potentially resulting in the development ... -
Biochemical and functional characterization of human MSL2
(2013-04-10)DNA in Eukaryotic cells is complexed with histone proteins to form chromatin. This mediates DNA packaging into the nucleus but also facilitates the regulation of all DNA-templated processes, including transcription, ... -
Centrobin functions in centriole duplication, primary ciliogenesis and genome maintenance
(2018-03-06)The centrosome is composed of numerous proteins that make up its core structure. Other proteins also transiently localise and interact with centrosomal proteins for functional modulation. Centrobin, one of the core centrosomal ... -
Centrosome cohesion: functions of C-NAP1
(2016-01-07)Double stranded DNA encodes the genetic material of the cell. Replication and segregation cycles are regulated in order to maintain the integrity of the DNA sequence from one cell cycle to the next. Detection of lesions ... -
Characterisation of novel ATM-interacting factors involved in double-strand break repair
(2012-10-22)Ataxia-telangiectasia (A-T) is a rare human disease characterized by cerebellar degeneration, immune system defects and cancer predisposition. The disease has been the subject of intense scientific scrutiny, particularly ... -
Characterisation of three zinc finger proteins ZC3H8, ZC3H11A and ZC3H14, identified as new partners of ATM, the central regulator of biological response to DNA double strand breaks
(NUI Galway, 2019-12-16)The integrity of our genome is very important therefore, our cells have developed efficient DNA repair mechanisms to control this integrity and avoid mutations. Although the DNA double strand break response pathway is ... -
DNA damage and induction of apoptosis in pancreatic cancer cells by a new dinuclear bis(triazacyclonane) copper complex
(Elsevier, 2015-01-26)The dinuclear copper(II) complex [Cu-2{bcmp(-H)}(mu-OH)](NO3)(2)center dot H2O (1, bcmp = 2,6-bis(1,4,7-triazacyclonon-1-ylmethyl)-4-methylphenol) has been synthesized and characterized by electrospray ionization mass ... -
Electrochemiluminescence arrays for studies of metabolite-related toxicity
(Wiley-Blackwell, 2016-06-01)This article reviews recent progress from our laboratory in electrochemiluminescence (ECL) arrays designed for screening toxicity-related chemistry of chemical and drug candidates. Cytochrome P450s and metabolic bioconjugation ... -
Histone h2ax y142 phosphorylation is a low abundance modification
(Elsevier BV, 2015-11-01) -
Impacts of DNA damage on the pericentriolar material and centriole duplication
(2015-12-03)The centrosome consists of two barrel-shaped centrioles embedded in a proteinaceous pericentriolar material (PCM), a highly organised scaffold that serves as a platform for proteins that regulate spindle assembly, protein ... -
KIF18B, a nuclear kinesin, is involved in DNA damage response
(NUI Galway, 2021-03-08)DNA damage from both exogenous and endogenous sources occurs continuously in all cells. A multitude of DNA repair mechanisms have evolved to maintain genome stability. The 53BP1 tumour suppressor has been identified as a ... -
The kinesin KIF18B interacts with 53BP1 and is required for efficient double strand break repair
(2015-11-19)Genetic changes can lead to detrimental genomic instability, mutagenesis, oncogenesis and premature aging. The DNA damage response (DDR) is responsible for safeguarding the genome from such harmful alterations. 53BP1 ... -
Microrna-29a regulates the benzo[a]pyrene dihydrodiol epoxide-induced dna damage response through cdc7 kinase in lung cancer cells
(Springer Nature, 2013-07-01)Cdc7 kinase is a key regulator of DNA replication and has an important role in the cellular DNA damage response by controlling checkpoint signaling and cell survival. Yet, how the activity of Cdc7 kinase is regulated is ... -
Mrc1, Tof1 and Csm3 inhibit CAG·CTG repeat instability by at least two mechanisms
(Springer, 2008)Trinucleotide repeats frequently expand and contract in humans and model organisms. Protein factors that modulate this process have been found by candidate gene approaches or mutant screens for increased expansion ... -
Nucleolar reorganisation promotes repair of rDNA double strand breaks by homologous recombination throughout the cell cycle.
(2013-12-16)The nucleolus is the largest functional domain within the nucleus and is the site of ribosome biogenesis. It has a distinct structure and houses ribosomal RNA gene (rDNA) transcription, pre-ribosomal RNA (pre-rRNA) processing, ... -
Programmed DNA damage in myogenesis
(2017-02-23)Skeletal muscle is a major tissue type in humans, comprising approximately 40% of total body mass in adults. Skeletal muscle is ultimately composed of elongated multinucleate cells known as myofibers. These myofibers are ... -
