Project description:HIF-metagene identifies hypoxic or constitutive HIF activation in scRNA-seq. Hypoxic normal cells have higher HIF-metagene scores than normoxic normal cells, and ccRCC tumour cells (harbouring VHL inactivation) have higher HIF-metagene score than normal cells.

Project description:Triple negative breast cancer (TNBC) is the most aggressive breast cancer subtype and the lack of specific signature makes difficult the development of targeted therapeutic strategy. We previously found that PRICKLE1, an evolutionary conserved protein acting as a regulator of vertebrate development, is upregulated in TNBC. Proteomic approaches allowed us to decipher the protein complex associated to PRICKLE1 in TNBC. Within that complex, we identified a large subset of proteins involved in the regulation of Rho-GTPase family members. We build a metagene with regulators of small G-protein activity and we found that this metagene is overexpressed in TNBC and is a poor prognosis marker. We analyzed the combination of the metagene expression and PRICKLE1 expression and identified that combined expression of ECT2 and PRICKLE1 provides a worst prognosis than PRICKLE1 expression alone in TNBC. ECT2 is a GEF for Rac1 and we showed that PRICKLE1 regulate the enzymatic activity of ECT2. Finally, we also observed that Ect2 and Prickle1 are functionally connected during evolution since both act synergistically to coordinate cellular movement during vertebrate gastrulation. Our results demonstrate the pivotal role of PRICKLE1 in TNBC and build the path for development of targeted therapeutic strategies to heal TNBC patients.

Project description:We isolated nuclear mRNPs from yeast using an endogenous bi-molecular tagging approach on Sub2 and Hpr1. To validate the nature of these isolated particles, extracted RNA was sequenced and differential enrichment, as well as metagene coverage analysis were performed.

Project description:Soil transplant serves as a proxy to simulate climate change in realistic climate regimes. Here, we assessed the effects of climate warming and cooling on soil microbial communities, which are key drivers in Earth’s biogeochemical cycles, four years after soil transplant over large transects from northern (N site) to central (NC site) and southern China (NS site) and vice versa. Four years after soil transplant, soil nitrogen components, microbial biomass, community phylogenetic and functional structures were altered. Microbial functional diversity, measured by a metagenomic tool named GeoChip, and phylogenetic diversity are increased with temperature, while microbial biomass were similar or decreased. Nevertheless, the effects of climate change was overridden by maize cropping, underscoring the need to disentangle them in research. Mantel tests and canonical correspondence analysis (CCA) demonstrated that vegetation, climatic factors (e.g., temperature and precipitation), soil nitrogen components and CO2 efflux were significantly correlated to the microbial community composition. Further investigation unveiled strong correlations between carbon cycling genes and CO2 efflux in bare soil but not cropped soil, and between nitrogen cycling genes and nitrification, which provides mechanistic understanding of these microbe-mediated processes and empowers an interesting possibility of incorporating bacterial gene abundance in greenhouse gas emission modeling.
