Spontaneous mutation accumulation in multiple strains of the green alga, Chlamydomonas reinhardtii

open access: yes, 2014
Estimates of mutational parameters, such as the average fitness effect of a new mutation and the rate at which new genetic variation for fitness is created by mutation, are important for the understanding of many biological processes. However, the causes

Mutational spectra and mutational signatures:insights into cancer aetiology and mechanisms of DNA damage and repair [PDF]

open access: yes, 2018
Reporter gene assays, in which a single mutation from each experiment can contribute to the assembly of a mutation spectrum for an agent, have provided the basis for understanding the mutational processes induced by mutagenic agents and for providing ...

A mutational scar-based genome-wide map of DNA double-strand break repair

open access: yesNature Communications
Genome alterations arise from inaccurate DNA repair and accumulate as distinct mutational signatures. Here, we systematically interrogate the contribution of every protein-coding gene to double-strand break (DSB) repair by generating high-resolution ...

Hippo pathway at the crossroads of stemness and therapeutic resistance in breast cancer

open access: yesMolecular Oncology, EarlyView.
Dysregulation of the Hippo pathway drives nuclear accumulation of YAP/TAZ, activating stemness‐related transcriptional programs that sustain breast cancer stemness and fuel therapeutic resistance across subtypes, underscoring Hippo signaling as a targetable vulnerability. Figure created and edited with BioRender.com.

Analysis of the DNA damage response in living cells [PDF]

open access: yes, 2007
DNA lesions arising from environmental and endogenous sources induce various cellular responses including cell cycle arrest, DNA repair and apoptosis. Although detailed insights into the biochemical mechanisms and composition of DNA repair pathways have ...

Rare Primary Mitochondrial DNA Mutations and Probable Synergistic Variants in Leber’s Hereditary Optic Neuropathy

open access: yes, 2012
Background Leber’s hereditary optic neuropathy (LHON) is a maternally inherited blinding disorder, which in over 90% of cases is due to one of three primary mitochondrial DNA (mtDNA) point mutations (m.11778G>A, m.3460G>A and m.14484T>C, respectively ...

Analysis of mutational signatures in C. elegans:Implications for cancer genome analysis

open access: yes, 2020
Genome integrity is constantly challenged by exogenous and endogenous insults, and mutations are associated with inherited disease and cancer. Here we summarize recent studies that utilized C.

Deciphering transcriptional plasticity in pancreatic ductal adenocarcinoma reveals alterations in sensory neuron innervation

open access: yesMolecular Oncology, EarlyView.
Pancreatic sensory neurons innervating healthy and PDAC tissue were retrogradely labeled and profiled by single‐cell RNA sequencing. Tumor‐associated innervation showed a dominant neurofilament‐positive subtype, altered mitochondrial gene signatures, and reduced non‐peptidergic neurons.

An assessment of the impact of environmental factors on the quality of post-mortem DNA profiling.

open access: yes, 2009
DNA profiling has ignited public interest and consequently their expectations for the capabilities of forensic criminal and science investigations. The prospect of characterising the genetic makeup of individuals or trace samples from a wide variety of ...

Indirect DNA Readout by an H-NS Related Protein: Structure of the DNA Complex of the C-Terminal Domain of Ler

open access: yes, 2011
Ler, a member of the H-NS protein family, is the master regulator of the LEE pathogenicity island in virulent Escherichia coli strains. Here, we determined the structure of a complex between the DNA-binding domain of Ler (CT-Ler) and a 15-mer DNA duplex.
