Abstract

Head and neck squamous cell carcinoma (HNSCC) ranks as the sixth most common cancer globally. Most studies in HNSCC demonstrated that regulatory T (Treg) cells confine the anti-tumor activity of effector T cells which may contribute to the immune escape and uncontrolled tumor progression. Here, we uncovered that the specific abrogation of Bcl6 in Treg cells resulted in significantly delayed malignant transformation of 4NQO-induced tumorigenesis. Bcl6 deficiency impairs the lineage stability of Treg cells by down-regulating the histone H3K4 trimethylation. Importantly, Bcl6 inhibition repressed the tumor growth of murine HNSCC and exhibited synergistic effects with immune checkpoint blockade therapy. These findings suggest that Bcl6 can be exploited as a promising therapeutic target for HNSCC treatment.

期刊介绍： Genes & Diseases is an international journal for molecular and translational medicine. The journal primarily focuses on publishing investigations on the molecular bases and experimental therapeutics of human diseases. Publication formats include full length research article, review article, short communication, correspondence, perspectives, commentary, views on news, and research watch. Aims and Scopes Genes & Diseases publishes rigorously peer-reviewed and high quality original articles and authoritative reviews that focus on the molecular bases of human diseases. Emphasis will be placed on hypothesis-driven, mechanistic studies relevant to pathogenesis and/or experimental therapeutics of human diseases. The journal has worldwide authorship, and a broad scope in basic and translational biomedical research of molecular biology, molecular genetics, and cell biology, including but not limited to cell proliferation and apoptosis, signal transduction, stem cell biology, developmental biology, gene regulation and epigenetics, cancer biology, immunity and infection, neuroscience, disease-specific animal models, gene and cell-based therapies, and regenerative medicine.
