Project Title:Investigative needle core biopsies for multi-omics in Glioblastoma
Project Type:Single Cell Spatial Analysis Reveals the Topology of Immunomodulatory Purinergic Signaling in Glioblastoma
Project Summary:Glioblastoma (GBM) is a primary brain cancer with an abysmal prognosis and few effective therapies. The ability to investigate the tumor microenvironment before and during treatment would greatly enhance both our understanding of disease response and progression, as well as the delivery and impact of therapeutics. Stereotactic biopsies are a routine surgical procedure performed primarily for diagnostic histopathologic purposes. The role of investigative biopsies – tissue sampling for the purpose of understanding tumor microenvironmental responses to treatment using integrated multi-modal molecular analyses (‘Multi-omics”) has yet to be defined. Here we adapt stereotactic needle core biopsy tissue for highly resolved multi-omics analysis methods including single cell RNA sequencing, spatial-transcriptomics, metabolomics, proteomics, phosphoproteomics, T-cell clonotype analysis, and MHC Class I immunopeptidomics. Biopsy tissue was obtained from a single patient with recurrent GBM during one procedure. In a second patient, we analyzed multi-regional core biopsies to decipher spatial and genomic variance. Finally in a separate cohort of patients we investigated the utility of stereotactic biopsies as a method for generating patient derived xenograft models. Dataset integration across modalities showed good correspondence between spatial modalities and highlighted immune cell associated metabolic pathways and poor correlation between RNA expression and the tumor MHC Class I immunopeptidome. In conclusion, stereotactic needle biopsy cores are of sufficient quality for the purposes of investigative biopsy and can generate multi-omics data, providing data rich insight into a patient’s disease process and tumor immune microenvironment and could be of potential value in evaluating treatment responses.
