MetabolomicsIntraspecific competition drives orthogonal variation in root exudate metabolic and functional traits in a dominant plant species’ seedlings

1. Classical plant functional traits, often limited by intercorrelation and incomplete capture of dynamic variation, are insufficient for fully predicting ecological responses to environmental change. Quantifying independent functional dimensions, particularly those reflecting molecular and bioch...

MetabolomicsAntibiotics create a shift from mutualism to competition in human gut communities with a longer-lasting impact on fungi than bacteria

Background

Antibiotic treatment has a well-established detrimental effect on the gut bacterial composition, but effects on the fungal community are less clear. Bacteria in the lumen of the gastrointestinal tract may limit fungal colonization and invasion. Antibiotic drugs t...

TranscriptomicsDifferent isoforms of Maxwell´s Demon, a conserved cell membrane protein, mediate lose/win decisions during cell competition
Cell competition promotes the elimination of weaker cells from a growing population. Here we investigate how cells of Drosophila wing imaginal discs distinguish “winners” from “losers” during cell competition. Using genomic and functional assays we have identified Maxwell`s Demon (Mwd), a cell membr...

TranscriptomicsCell competition regulates thymocyte turnover
Wild type thymi were transplanted into a competitive (wild type hosts), or non-competitive (Rag2-/-γc-/-KitW/Wv hosts) environment. Triple negative 2 and 3 (TN2/3) stages were sorted 14 days afetr transplantation and separated for cells of host or donor origin. Global gene expression data for TN2/3 ...

MetabolomicsMg2+ in drinking water exacerbates Salmonella Typhimurium T6SS-mediated intestinal bacterial competition through affecting metabolic reprogramming

By establishing a model of enteritis in mice infected with Salmonella Typhimurium, this study investigates the effects of ion concentration in drinking water on intestinal metabolites and microbiota structure in mice, as well as its influence on pathogen susceptibility and the host-patho...

MetabolomicsVariations in carbon flux allocation among cassava (Manihot esculenta) cultivars arise from balanced competition between starch accumulation and structural component development

Cassava (Manihot esculenta Crantz) storage roots exhibit significant variation in starch content among cultivars, yet the metabolic and molecular mechanisms governing carbon allocation between storage and structural components remain poorly understood. Here, we investigated carbon partitioning in...

TranscriptomicsMyc mild overexpression in the heart in a mosaic fashion induces matabolic changes and triggers hipertrophic protection pathways without a pathological phenotype
Recently, it was described that mammalian cells are able to eliminate those with relative lower Myc levels in the epiblast through cell competition. We have described that cardiomyocytes during heart development are also able to complete eliminating cells with lower Myc levels. We have also shown th...

TranscriptomicsTranscriptome analyses during disease progression
Transcriptome was assessed in the transitions from the normal thymus (with regular progenitor turnover), to a thymus devoid of extrinsic progenitor competition for 10 weeks, to fully malignant T cell acute lymphoblastic leukemia (T-ALL). Comparison of global gene expression between normal thymus, to...
