Genomic and Transcriptomic Landscape of an Oral Squamous Cell Carcinoma Mouse Model for Immunotherapy.

ABSTRACT: The immune checkpoint inhibitor (ICI), anti-programmed death-1 (anti-PD-1), has shown moderate efficacy in some patients with head and neck squamous cell carcinoma (HNSCC). Because of this, it is imperative to establish a mouse tumor model to explore mechanisms of antitumor immunity and to develop novel therapeutic options. Here, we examined the 4-nitroquinoline-1-oxide (4NQO)-induced oral squamous cell carcinoma (OSCC) model for genetic aberrations, transcriptomic profiles, and immune cell composition at different pathologic stages. Genomic exome analysis in OSCC-bearing mice showed conservation of critical mutations found in human HNSCC. Transcriptomic data revealed that a key signature comprised of immune-related genes was increased beginning at the moderate dysplasia stages. We first i
