Bulletin des Sciences Mathématiques, 2018 We study mutations of Conway-Coxeter friezes which are compatible with mutations of cluster-tilting objects in the associated cluster category of Dynkin type $A$. More precisely, we provide a formula, relying solely on the shape of the frieze, describing how each individual entry in the frieze changes under cluster mutation.

arXiv, 2023 A mutation cycle is a cycle in a graph whose vertices are labeled by the quivers in a given mutation class and whose edges correspond to single mutations. For any fixed $n\ge 4$, we describe arbitrarily long mutation cycles involving $n$-vertex quivers.

Nature Communications, 2018 This Article contains errors in Fig. 3, Fig. 4 and Fig. 7, for which we apologize. In Fig. 3, panel ‘b’, the 0.5 hour time point after Ku55933 treatment images were inadvertently replaced with duplicates of the 3 hour time point after Ku55933 treatment ...

A Spatial Mutation Model with Increasing Mutation Rates [PDF]
arXiv, 2021 We consider a spatial model of cancer in which cells are points on the $d$-dimensional torus $\mathcal{T}=[0,L]^d$, and each cell with $k-1$ mutations acquires a $k$th mutation at rate $\mu_k$. We will assume that the mutation rates $\mu_k$ are increasing, and we find the asymptotic waiting time for the first cell to acquire $k$ mutations as the torus ...

Mutation Spectra and the Neutrality of Mutations [PDF]
Australian Journal of Biological Sciences, 1974 The effect of amino acid replacements on enzyme function was studied in the tJ-galactosidase of Escherichia coli. Mutants possessing 50% or less of normal enzyme activity were isolated and examined. Of 733 amino acid substitutions calculated to have occurred, only 11 reduced tJ-galactosidase activity below 50 %.

ID3 regulates the MDC1-mediated DNA damage response in order to maintain genome stability
Nature Communications, 2017 MDC1 is a key component of the DNA damage response and interacts with several factors such as γ-H2AX. Here the authors show that MDC1 interacts with ID3, facilitating MDC1 recruitment to sites of damage and repair of breaks.

Plants, 2022 Mutagenic effectiveness and efficiency are the most important factors determining the success of mutation breeding, a coherent tool for quickly enhancing genetic diversity in crops. However, conclusive evidence of using an effective and efficient dose of
