The paradox of cooperation among selfish cancer cells

open access: yesEvolutionary Applications, 2023
It is traditionally assumed that during cancer development, tumor cells abort their initially cooperative behavior (i.e., cheat) in favor of evolutionary strategies designed solely to enhance their own fitness (i.e., a “selfish” life style) at the ...

Negative frequency dependent selection unites ecology and evolution

open access: yesEcology and Evolution, 2023
From genes to communities, understanding how diversity is maintained remains a fundamental question in biology. One challenging to identify, yet potentially ubiquitous, mechanism for the maintenance of diversity is negative frequency dependent selection (

Breeding system study in sunnhemp (Crotalaria juncea L.) A stepping stone in crop improvement

open access: yesElectronic Journal of Plant Breeding, 2020
Sunnhemp (Crotalaria juncea L.) belonging to the family Fabaceae is having wide range of industrial utilization as fibre crop, fodder crop and green manure. Pollination is the key mutualism between two kingdoms of organisms.

The Fungal Aroma Gene ATF1 Promotes Dispersal of Yeast Cells through Insect Vectors

open access: yesCell Reports, 2014
Yeast cells produce various volatile metabolites that are key contributors to the pleasing fruity and flowery aroma of fermented beverages. Several of these fruity metabolites, including isoamyl acetate and ethyl acetate, are produced by a dedicated ...

Humanin vitrofertilisation and developmental biology: a mutually influential history [PDF]

open access: yesDevelopment, 2019
ABSTRACTThis article describes the origins and development of in vitro fertilisation (IVF) and how it was influenced by, and influenced, basic research in developmental biology. It describes the technical and social challenges that confronted the pioneers in this field of study, and the considerable progress that has been made since those early days ...

Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

The importance of being persistent: The first true resident gut symbiont in Drosophila. [PDF]

open access: yesPLoS Biology, 2018
In the animal kingdom, nutritional mutualism is a perpetual and intimate dialogue carried out between the host and its associated gut community members. This dialogue affects many aspects of the host's development and physiology. Some constituents of the

A novel independence test for somatic alterations in cancer shows that biology drives mutual exclusivity but chance explains co-occurrence [PDF]

open access: yesGenome Biology, 2016
AbstractJust like recurrent somatic alterations characterize cancer genes, mutually exclusive or co-occurring alterations across genes suggest functional interactions. Identifying such patterns in large cancer studies thus helps the discovery of unknown interactions. Many studies use Fisher’s exact test or simple permutation procedures for this purpose.

Multiple ETS family transcription factors bind mutant p53 via distinct interaction regions

open access: yesFEBS Letters, EarlyView.
Mutant p53 gain‐of‐function is thought to be mediated by interaction with other transcription factors. We identify multiple ETS transcription factors that can bind mutant p53 and found that this interaction can be promoted by a PXXPP motif. ETS proteins that strongly bound mutant p53 were upregulated in ovarian cancer compared to ETS proteins that ...

Reproductive biology of pointleaf manzanita (Arctostaphylos pungens) and the pollinator-nectar robber spectrum

open access: yesJournal of Pollination Ecology, 2012
Floral visitor species are often assumed to act either mutualistically towards plants (as pollinators) or to exploit them (as nectar-robbers or as nectar or pollen thieves).
