Targeted Prevention of Non-Melanoma Skin Cancer

Skin cancer is the most common malignancy worldwide.  One out of three new cancers is a skin cancer. Approximately 5 million cases of non-melanoma skin cancer (NMSC) – basal cell carcinoma (BCC) and cutaneous squamous cell carcinomas (cSCC) occur annually.  Incidence rates for NMSC continue to rise, creating a substantial impact on morbidity and health care costs that account for $8.1 billion a year for skin cancer treatment. The majority of these lesions represent keratinocytic neoplasms. The overall goal of this multi-institutional Program Project Grant (PPG) is to employ novel technologies and develop new targeted prevention strategies to eradicate intraepithelial neoplasias in the skin (e.g. actinic keratosis, squamous cell carcinoma in situ), and thereby, to dramatically reduce the risk of cSCC.

To achieve this goal, we will conduct a multilevel program of rational drug development, including:

1) To assess, in experimental models and human studies, the significance of TLR4 and TOPK/PRPK signaling pathways in skin carcinogenesis leading to cSCC development

2) To evaluate the relationship between TLR4 and TOPK/PRPK activation and previously established signaling pathways of relevance in AK and cSCC development

3) To identify and develop novel therapeutic preventive agents that specifically “hit” these molecular targets in cSCC mouse models and effectively modulate their signaling pathways

4) To test the most promising target-specific agents in preclinical pharmacology models

5) To assess target engagement and safety of selected agents through pilot and Phase 1 clinical trials

Knowledge of the key molecular targets in solar ultraviolet (UV) radiation signaling pathways and the development of multiple topically administered agents that can hit and effectively modulate these targets ultimately will allow for precision medicine-based approaches in cSCC prevention. While the two basic science projects (Projects 1 and 2) aim to identify and validate UV-induced signaling pathways and agents that modulate these targets, the clinical project (Project 3) will undertake the task of moving leading candidate drugs from mouse models into acute solar simulated light studies and Phase 1 clinical trials. 

Novel technologies include signaling network analysis using state-of-the-art proteomic arrays coupled with the latest exploratory and downstream bioinformatic approaches and in vivo reflectance confocal microscopy for non-invasive assessment and selection of tissue samples in human skin. This highly integrated and translational research-based program project, emphasizing a multidisciplinary, precision medicine approach for the prevention of cSCC of the skin can also serve as a model for preventing other epithelial malignancies.
