Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

open access: yesMolecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Large chromosomal structural variations between M. acuminata and M balbisiana and their consequences on chromosome recombination and segregation in a AAAB polyploidy context [PDF]

open access: yes, 2017
Many banana cultivars are triploid interspecific hybrids between M. acuminata (Genome A, 2n=22) and M. balbisiana (Genome B, 2n=22). They included the important group of Plantain cooking bananas classified as AAB.

Multidirectional chromosome painting substantiates the occurrence of extensive genomic reshuffling within Accipitriformes. [PDF]

open access: yes, 2015
BACKGROUND: Previous cross-species painting studies with probes from chicken (Gallus gallus) chromosomes 1-10 and a paint pool of nineteen microchromosomes have revealed that the drastic karyotypic reorganization in Accipitridae is due to extensive ...

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

open access: yesMolecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

A new species in the Hieracium lycopifolium agg. (Asteraceae) from the Western Carpathians

open access: yesActa Societatis Botanicorum Poloniae, 2011
Hieracium zajacii Szeląg is described from the Vel'ká Fatra Mts in Slovakia. It is the first representative of H. lycopifolium agg. to be found in the Carpathians. The new species is tetraploid (2n = 36) and reproduces apomictically.

Pre‐ and postzygotic mechanisms preventing hybridization in co‐occurring species of the Impatiens purpureoviolacea complex

open access: yesEcology and Evolution, 2021
In the species‐rich genus Impatiens, few natural hybrids are known, even though closely related species often occur sympatrically. In this study, we aim to bridge the gap between micro‐ and macro‐evolution to disentangle pre‐ and postzygotic mechanisms ...

The elusive evidence for chromothripsis. [PDF]

open access: yes, 2014
The chromothripsis hypothesis suggests an extraordinary one-step catastrophic genomic event allowing a chromosome to 'shatter into many pieces' and reassemble into a functioning chromosome.

Somatic mutational landscape in von Hippel–Lindau familial hemangioblastoma

open access: yesMolecular Oncology, EarlyView.
The causes of central nervous system (CNS) hemangioblastoma in Von Hippel–Lindau (vHL) disease are unclear. We used Whole Exome Sequencing (WES) on familial hemangioblastoma to investigate events that underlie tumor development. Our findings suggest that VHL loss creates a permissive environment for tumor formation, while additional alterations ...

On a break with the X: the role of repair of double-stranded DNA breaks in X-linked disease [PDF]

open access: yes, 2012
The problem of managing free reactive DNA ends in eukaryotic cells has resulted in the development of a number of mechanisms in order to ensure that free ends are rendered non-reactive, or that the double-strand DNA breaks generating the free ends are ...
