Cell‐cycle‐specific lesion evolution rather than inhibition of double‐strand‐break repair underpins cisplatin radiosensitization

open access: yesMolecular Oncology, EarlyView.
We analyze cisplatin–DNA adducts (CDAs) and double‐strand breaks (DSBs) in a cell‐cycle‐dependent manner. We find that CDAs form similarly across all cell cycle phases. DSBs arise only in S‐phase. CDAs might not directly impair DSB repair, but S‐phase DSB lesions evolve in the presence of CDAs and disrupt repair in G2, also causing radiosensitization ...

Inferring kangaroo phylogeny from incongruent nuclear and mitochondrial genes

open access: yes, 2013
The marsupial genus Macropus includes three subgenera, the familiar large grazing kangaroos and wallaroos of M. (Macropus) and M. (Osphranter), as well as the smaller mixed grazing/browsing wallabies of M. (Notamacropus).

A dated phylogeny and collection records reveal repeated biome shifts in the African genus Coccinia (Cucurbitaceae) [PDF]

open access: yes, 2011
Background: Conservatism in climatic tolerance may limit geographic range expansion and should enhance the effects of habitat fragmentation on population subdivision.

The complete mitochondrial genome and phylogenetic analysis of Leptobotia bellacauda (Teleostei: Cypriniformes: Botiidae)

open access: yesMitochondrial DNA. Part B. Resources
The complete mitochondrial genome of Leptobotia bellacauda was sequenced and characterized for the first time. The mitogenome was a 16,591 bp circular molecule, including 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, two ribosomal RNA ...

Biogeographic history of the endangered dwarf buffalo, subgenus Anoa (Bovidae: Bubalus quarlesi and Bubalus depressicornis): a perspective based on mitochondrial DNA phylogeny [PDF]

open access: yesEvolutionary Systematics
The Anoa, including the Mountain Anoa (Bubalus quarlesi) and the Lowland Anoa (Bubalus depressicornis) according to current taxonomy, are endangered bovid species endemic to the tropical island of Sulawesi.

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

open access: yesMolecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Phylogenomics and barcoding of Panax: toward the identification of ginseng species

open access: yesBMC Evolutionary Biology, 2018
Background The economic value of ginseng in the global medicinal plant trade is estimated to be in excess of US$2.1 billion. At the same time, the evolutionary placement of ginseng (Panax ginseng) and the complex evolutionary history of the genus is ...

Longitudinal circulating tumor DNA profiling in patients with advanced endometrial cancer using an off‐the‐shelf targeted NGS panel

open access: yesMolecular Oncology, EarlyView.
Intratumour heterogeneity complicates precision management of advanced endometrial cancer. Circulating tumor DNA (ctDNA) offers a minimally invasive strategy to capture tumor evolution and therapeutic resistance. Here, we compare tumor‐agnostic NGS with tumor‐informed ddPCR, outlining their relative sensitivity, concordance, and clinical implications ...

ESR1 methylation and ESR1 mutations in circulating tumor cells (CTCs) and paired plasma‐cfDNA of advanced breast cancer patients: A feasibility proof‐of‐concept study

open access: yesMolecular Oncology, EarlyView.
Circulating tumor cells (CTCs) and plasma cell‐free DNA (cfDNA) were analyzed to detect ESR1 mutations and methylation in patients with advanced breast cancer. CTC‐derived DNA showed higher sensitivity for mutation detection and revealed complementary genetic and epigenetic alterations, highlighting the added value of CTC analysis for understanding ...
