Project description:Host responses to intracellular UPEC communities We used laser capture microdissection and microarrays to identify urothelial transcripts differentially expressed in response to proximity to intracellular UPEC. Keywords: spatial/cell type analysis
Project description:Genomic DNA extracted from two different Photobacterium profundum strains: SS9 strain (completely sequenced and used to made the microarray) and DSJ4 strain were labeled with Cy3 and Cy5 fluorophores and competitively hybridized on the microarray built on the basis of the SS9 strain genomic sequence. Aim: the identification of the genomic regions absent in the DSJ4 strain with respect to the SS9 strain. The SS9 strain was isolated from the Sulu Trench and display an optimum growth at 28 MPa (2800 metres of depth). The DSJ4 strain was recovered from a sediment sample obtained from the Ryukyu Trench (Japan) at a depth of 5110 m and displays an optimum growth at 10 MPa (but shows no significant change in growth at pressure up to 50 MPa).

Project description:Pancreatic ductal adenocarcinoma (PDAC) is a highly lethal and treatment-refractory cancer. Molecular stratification in pancreatic cancer remains rudimentary and does not yet inform clinical management or therapeutic development. Here we construct a high-resolution molecular landscape of the multicellular subtypes and spatial communities that compose PAC using single-nucleus RNA-seq and whole-transcriptome digital spatial profiling (SP) of 43 primary PDAC tumor specimens that either received neoadjuvant therapy or were treatment-naïve. We uncovered expression programs across malignant cells and fibroblasts, including a newly-identified neural-like progenitor malignant cell program that was enriched after chemotherapy and radiotherapy and associated with poor prognosis in independent cohorts. Integrating spatial and cellular profiles revealed three multicellular communities: classical, squamoid-basaloid, and treatment-enriched. Our refined molecular and cellular taxonomy can advance precision oncology in PAC through stratification in clinical trials and as roadmap for therapeutic targeting of specific cellular phenotypes and multicellular interactions.
