Head and neck squamous cell carcinoma (HNSCC) remains a leading cause of cancer deaths worldwide with ~500,000 cases/year. Cisplatin is the gold standard systemic agent for HNSCC. Cisplatin resistance, both intrinsic and acquired, has been described in preclinical models and is frequently encountered in clinical practice; when it occurs, it is deadly. The overarching goal of H-CARR is to develop a robust biological understanding of the key drivers of cisplatin resistance in HNSCC and develop the means of detecting it early in development and overcoming it once it arises.
H-CARR team previously showed that: 1) cellular processing of cisplatin-generated metabolic stress is a critical driver of sensitivity and/or resistance and 2) coordinated genomic (TP53 mutation) and transcriptomic (Nrf-2 activation) reprogramming is essential to organizing the metabolic response to cisplatin generated stress. H-CARR brings together biological and metabolic models of cisplatin resistance and extensive translational capabilities to image tumor metabolism non-invasively and detect biological shifts using circulating tumor cells (CTCs), providing a comprehensive window into development of cisplatin resistance.
H-CARR investigates convergent mechanisms of treatment resistance, altered metabolism and suppressed anti-tumor immunity synergistically and iteratively via 3 Research Projects:
Project 1:
Metabolic adaptation enables cisplatin resistance and inhibits tumor immunity
Project 2:
Defining the role of KEAP1/NRF2 signaling dysregulation and sensory nerve reprograming during acquisition of cisplatin resistance and metastasis in HNSCC.
Project 3:
Quantification of cisplatin sensitivity and resistance using metabolic imaging and circulating tumor cell (CTC) biomarkers.

H-CARR is supported by a robust administrative and analytical infrastructure organized into 3 Cores.
An Administrative Core provides critical centralized support to H-CARR investigators and ensures seamless interactions and integration between the three projects and cores within the center as well as the broader ARTNet community.
A Systems Bioinformatics Core coalesces the data streams from all 3 Projects into one coherent multi 'omics understanding of cisplatin response and development of resistance.
A Tumor Model and Biospecimen Repository Core provides H-CARR investigators with a centralized facility that ensures the systematic collection, processing, storage, and distribution of peripheral blood, surrogate and specialized specimens, and samples of head and neck squamous cell carcinoma (HNSCC) from patients.
