Cancer cell states recur across tumor types and form specific interactions with the tumor microenvironment.

ABSTRACT: Transcriptional heterogeneity among malignant cells of a tumor has been studied in individual cancer types and shown to be organized into cancer cell states; however, it remains unclear to what extent these states span tumor types, constituting general features of cancer. Here, we perform a pan-cancer single-cell RNA-sequencing analysis across 15 cancer types and identify a catalog of gene modules whose expression defines recurrent cancer cell states including 'stress', 'interferon response', 'epithelial-mesenchymal transition', 'metal response', 'basal' and 'ciliated'. Spatial transcriptomic analysis linked the interferon response in cancer cells to T cells and macrophages in the tumor microenvironment. Using mouse models, we further found that induction of the interferon response module varies by tumor location and is diminished upon elimination of lymphocytes. Our work provides a framework for studying how cancer cell states interact with the tumor microenvironment to form organized systems capable of immune evasion, drug resistance and metastasis.

Project description:Gastric cancer (GC) heterogeneity between and within tumors represents a barrier to disease management. We generated a comprehensive single-cell atlas of GC comprising 31 primary gastric tumor samples representing clinical stages I-IV and histological subtypes. We identified 34 distinct cell-lineage states, related by developmental trajectories and previously unreported rare cell populations. Many lineage states exhibited a distinctive tumor-associated expression profile, each contributing individually to a combined tumor-wide molecular collage. We observed increased plasma cell proportions as a feature of diffuse-type tumors associated with epithelial-resident KLF2, and a stagewise accrual of novel cancer-associated fibroblast sub-populations marked by high INHBA and FAP co-expression. Our results provide a high-resolution molecular resource for GC translational studies, identifying intra- and inter-patient lineage-states across distinct GC subtypes. #### GEO title mapping with the ID in PMID:34642171 #### Manuscript_ID Primary_Tumor Primary_Normal Peritoneal_Tumor Peritoneal_Normal NGCII521 sample7.csv sample6.csv - - NGCII513 sample22.csv sample21.csv - - NGCII512 sample26.csv sample25.csv - - NGCII520 sample5.csv sample4.csv - - NGCII514 sample24.csv sample23.csv - - NGCII518 sample2.csv sample1.csv - - NGCII525 sample10.csv sample9.csv - - NGCII527 sample12.csv sample11.csv - - NGCII538 sample36.csv sample35.csv sample38.csv sample37.csv NGCII539 sample32.csv - - - NGCII529 sample13.csv - - - NGCII511 sample15.csv - - - NGCII498 sample18.csv - - - NGCII522 sample29.csv - - - NGCII499 sample16.csv - - - NGCII502 sample14.csv - - - NGCII509 sample17.csv - - - NGCII540 sample33.csv - - - NGCII541 sample34.csv - - - NGCII543 sample39.csv - - - NGCII510 sample27.csv - - - NGCII519 sample3.csv - - - NGCII531 sample28.csv - - - NGCII545 sample40.csv - - - NGCII533 sample30.csv - - - NGCII524 sample8.csv - - - NGCII536 - sample31.csv - - NGCII011 - - sample19.csv - NGCII015 - - sample20.csv -
