Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Dimethyl fumarate combined with cisplatin at subcytotoxic doses sensitizes cervical cancer toward ferroptosis and apoptosis through GSH restriction and p53 (re)activation

open access: yesMolecular Oncology, EarlyView.
Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.

Invasion Consequences in Communities Maintained by Niche and Intransitive Coexistence Mechanisms

open access: yesDiversity, 2023
Understanding invasion mechanisms or identifying their potential outcomes has been a longstanding objective of invasion. Many recent empirical and theoretical works tend to frame a perspective of invasion biology within the field of coexistence theory ...

Condensation and coexistence in a two-species driven model

open access: yes, 2004
Condensation transition in two-species driven systems in a ring geometry is studied in the case where current-density relation of a domain of particles exhibits two degenerate maxima.

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

open access: yesMolecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Nitrogen input enhances the impacts of emigration and immigration on plant species composition in a temperate grassland

open access: yesEcosphere
Human‐induced increase in atmospheric nitrogen (N) deposition has decreased species diversity at the local scale (α diversity) over global grasslands.

The Asian clam Corbicula fluminea, an accidental host for the European bitterling Rhodeus amarus

open access: yesKnowledge and Management of Aquatic Ecosystems
European bitterling (Rhodeus amarus) embryonic development depends entirely on freshwater mussels of the family Unionidae as host. As almost all the six widespread European unionid mussel species are declining in Southwestern Germany, this could result ...

The competition model with Holling type II competitive response to interfering time

open access: yesJournal of Biological Dynamics, 2020
In Nature, species coexistence is much more frequent than what the classical competition model predicts, so that scientists look for mechanisms that explain such a coexistence.

Free Energy Minimizers for a Two--Species Model with Segregation and Liquid-Vapor Transition

open access: yes, 2002
We study the coexistence of phases in a two--species model whose free energy is given by the scaling limit of a system with long range interactions (Kac potentials) which are attractive between particles of the same species and repulsive between ...

Testing mechanisms of compensatory fitness of dioecy in a cosexual world [PDF]

open access: yes, 2019
Questions: All else being equal, populations of dioecious species with a 50:50 sex ratio have only half the effective reproductive population size of bisexual species of equal abundance. Consequently, there is a need to explain how dioecious and bisexual
