Digital Spatial Profiling of immuno-oncology proteins in mouse hepatocellular carcinoma xenograft treated with THIO-based combination immune therapie
Ontology highlight
ABSTRACT: THIO (6-thio-dG) is a nucleoside analog that induces telomeric DNA damage and triggers activation of anti-tumor immunity in several cancer types such as lung and colorectal cancers. To evaluate its effect in hepatocellular carcinoma (HCC), THIO in combination with the current standard care first-line therapy for advanced HCC, anti-PD-L1 and anti-analyze, was tested in immunocompetent mice subcutaneously implanted with syngeneic HCC cell line (Hep55.1c). Formalin-fixed paraffin-embedded (FFPE) tumor tissues were collected after the treatment, and therapeutic modulations of the tumor immune landscape were assessed with Digital Spatial Profiling of 38 immuno-oncology-related proteins in region of interest (ROI) and intra-ROI segments enriched for T cells, other leukocytes, and HCC/stromal cells.
