Local canopy disturbance as an explanation for long-term increases in liana abundance.

Ecol Lett 2021 Sep 18. Epub 2021 Sep 18.

Department of Biological Sciences, Marquette University, Milwaukee, Wisconsin, USA.

Canopy disturbance explains liana abundance and distribution within tropical forests and thus may also explain the widespread pattern of increasing liana abundance; however, this hypothesis remains untested. We used a 10-year study (2007-2017) of 117,100 rooted lianas in an old-growth Panamanian forest to test whether local canopy disturbance explains increasing liana abundance. We found that liana density increased 29. Read More

Natural selection fluctuates at an extremely fine spatial scale inside a wild population of snapdragon plants.

Evolution 2021 Sep 17. Epub 2021 Sep 17.

PSL Université Paris: EPHE-UPVD-CNRS, USR 3278 CRIOBE, Université de Perpignan, 52 Avenue Paul Alduy, Perpignan Cedex, 66860, France.

Spatial variation in natural selection is expected to shape phenotypic variation of wild populations and drive their evolution. While evidence of phenotypic divergence across populations experiencing different selection regimes is abundant, investigations of intra-population variation in selection pressures remain rare. Fine-grained spatial environmental heterogeneity can be expected to influence selective forces within a wild population and thereby alter its fitness function by producing multiple fitness optima at a fine spatial scale.

Argininosuccinate lyase is a metabolic vulnerability in breast development and cancer.

NPJ Syst Biol Appl 2021 Sep 17;7(1):36. Epub 2021 Sep 17.

Center for Systems Biology, University of Iceland, Reykjavik, Iceland.

Epithelial-to-mesenchymal transition (EMT) is fundamental to both normal tissue development and cancer progression. We hypothesized that EMT plasticity defines a range of metabolic phenotypes and that individual breast epithelial metabolic phenotypes are likely to fall within this phenotypic landscape. To determine EMT metabolic phenotypes, the metabolism of EMT was described within genome-scale metabolic models (GSMMs) using either transcriptomic or proteomic data from the breast epithelial EMT cell culture model D492.

Genome-wide DNA methylation profile in feline haematological tumours: A preliminary study.

Res Vet Sci 2021 Sep 8;140:221-228. Epub 2021 Sep 8.

Veterinary Teaching Hospital, Graduate School of Veterinary Medicine, Hokkaido University, Japan.

Although DNA methylation has been analysed in few studies for a limited number of loci in cats with diseases, genome-wide profile of DNA methylation has never been addressed. The hypothesis for this study is that next-generation sequencing with sequential digestion of genomic DNA with SmaI and XmaI enzymes could provide highly quantitative information on methylation levels in cats. Using blood from four healthy control cats and two disease cats as well as three feline lymphoma/leukemia cell lines, approximately 74-94 thousand CpG sites across the cat genome could be analysed.
