Spatial transcriptomic analysis of tumoural (PanCK+) and stromal (PanCK-) regions in TNBC tissue samples using an immunoncology probe-based panel on the GeoMxâ„¢ Digital Spatial Profiler (DSP) This dataset was obtained by in-situ hybridisation of probes to a tissue microarray (TMA) of human triple-negative breast cancer (TNBC) tissue which was subsequently stained for Pan-cytokeratin (PanCK, Green) and cluster of differentiation 45 (CD45, Magenta). In-situ probes were cleaved from the tissue using UV-light according to immunofluorescence staining. These probes were then hybridised to reporter code sets (nCounter Nanostring) and quantified on the MAX/FLAX nCounter system accoridng to manufacturer instruction (FOV 555). The purpose of this dataset is to allow interrogation of the differential transcriptomic profiles of tumoural (PanCK+) and stromal (PanCK-) regions of TNBC disease to further investigate disease pathogenesis and spark hypothesis-driven research into potential new therapies and prognostic markers for patients with this subtype of disease. These data can be used for further transcriptomic analysis as a validation dataset or discovery dataset to investigate different mRNA expression levels of genes of interest. The data may be accessed via GeoMx Analysis Suite (avaliable at https://130.209.227.95/login) and/or visualised through importation into R Studio for comparative analysis. Files included: - Digital count files (dcc. files) from GeoMx nCounter (starting in 20210520_...) - Raw data exported from GeoMx Analysis Suite (see TNBC-raw-data-GeoMx.xlsx) - Normalised data exported from GeoMx Analysis Suite (performed using negative probe normalisation) (see TNBC-negprobe-normalised-data-all-GeoMx.xlsx) - Immunofluorescence images (.tiff) of TNBC TMAs All data has been anonymised for data protection purposes.
