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

Molecular 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

Audience effects in the Atlantic molly (Poecilia mexicana)-prudent male mate choice in response to perceived sperm competition risk? [PDF]

, 2009
Background Multidirectional interactions in social (or communication) networks can have a profound effect on mate choice behavior. For example, Poecilia mexicana males show weaker expression of mating preferences when being observed by an audience male ...

Hippo pathway at the crossroads of stemness and therapeutic resistance in breast cancer

Molecular Oncology, EarlyView.
Dysregulation of the Hippo pathway drives nuclear accumulation of YAP/TAZ, activating stemness‐related transcriptional programs that sustain breast cancer stemness and fuel therapeutic resistance across subtypes, underscoring Hippo signaling as a targetable vulnerability. Figure created and edited with BioRender.com.

Apparent competition and insect community structure: towards a spatial perspective

, 2005
Competition has been widely discussed as a process that may structure communities of plants and animals. Its role in insect communities is less clear, especially as many insect species do not appear to compete for resources.

Apparent competition, quantitative food webs, and the structure of phytophagous insect communities.

, 2006
Phytophagous insects and their natural enemies make up one of the largest and most diverse groups of organisms on earth. Ecological processes, in particular negative indirect effects mediated by shared natural enemies (apparent competition), may be ...

Plant diversity alters the representation of motifs in food webs

Nature Communications, 2019
Plant diversity affects ecosystem function in myriad ways, but the effect on food webs has received less investigation. Here, the authors use high-resolution food web data from a grassland diversity experiment to show that apparent and exploitative ...

Effect of Substrate Moisture Content and Invasive Grass Competition on Native Fig (Ficus fistulosa) Seedling Recruitment in Limestone Quarries

Biotropia: The Southeast Asian Journal of Tropical Biology, 2016
Challenges for restoration of degraded habitats on quarried limestone present in many countries including Indonesia. Ficus fistulosa as native species was chosen as a study species in the study of quarry restoration, as this species was shown in the ...

CD47 promotes mitogen‐activated protein kinase and epithelial‐to‐mesenchymal transition molecular programs to drive prometastatic phenotypes in non‐small cell lung cancer

Molecular Oncology, EarlyView.
Beyond its role in immune evasion, this study identified that CD47 drives tumor‐intrinsic signaling in non‐small cell lung cancer (NSCLC). Transcriptomic profiling and functional studies revealed that CD47 regulates cell adhesion, migration, and metastasis through an ERK–EMT signaling axis.

Apparent Competition between Myoglobin and Metallothionein for Renal Reabsorption

Experimental Biology and Medicine, 1978
SummaryArtery-to-vein and artery-to-urine transit characteristics of 125I-myoglobin across the rabbit kidney were compared to those of cadmium-metallothionein (CdMT) labelled with 109Cd, and their interaction during tubular reabsorption was determined.

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

Molecular 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 ...
