Skin Cancer

Current Projects
Trang Nguyen, PhD

Dr. Nguyen is focusing on the key molecular pathways involved in T-cell unresponsive states, which prevents a full immune response against cancer. Within the suppressive cancer environment, T cells stop recognizing and fighting cancer cells. Dr. Nguyen is examining new genes and pathways that activate T cells and overcome the defects of unresponsive T cells. The insights gained from these studies may inspire new therapeutic strategies for cancer immunotherapy.

Kavita Y. Sarin, MD, PhD

Basal cell cancer (BCC) is the most common cancer in the United States with 2 million cases annually resulting in $5 billion in societal cost. Although the majority of BCCs are small and surgically accessible, some individuals develop frequent recurrences of BCC and suffer from severe disability related to surgery and decreased quality of life. Dr. Sarin will focus on a group of 100 patients who develop extreme numbers of this skin cancer, in order to identify the genetic mechanisms that contribute to cancer susceptibility. While most BCCs are thought to develop from DNA damage caused by the sun’s ultraviolet rays, a patient’s genetics also play a critical role in disease progression. Understanding the mechanisms that contribute to cancer susceptibility will help identify at-risk individuals, so they can be monitored for earlier diagnosis and prevention. She also aims to develop new non-surgical therapies for these patients. Dr. Sarin works under the mentorship of Jean Y. Tang, MD, PhD, at Stanford University, Stanford.

Project title: "Genetic contributions and novel therapies for individuals with frequent basal cell cancer"
Institution: Stanford University
Award Program: Clinical Investigator

Adam J. Stevens, PhD

Dr. Stevens aims to discover how engineered immune cells may be applied to the treatment of solid tumors that limit the infiltration of endogenous T cells. Dr. Stevens is using protein engineering to design synthetic receptors that direct T cells to tumor-associated antigens and facilitate penetration into the tumor. Once inside the tumor, the engineered cells should serve as signaling hubs to recruit additional immune cells and kill the cancer cells.

Linghe Xi, PhD

Dr. Xi is studying signaling events that drive squamous cell carcinomas (SCCs), a common form of skin cancer. She focuses on WNT signaling, which is an important player in cell fate determination. It appears that WNT signaling is essential for SCC tumor formation, but exactly where and how it is required remains unknown. She is dissecting the activity of WNT signaling during the progression from normal epithelial cells to benign papillomas, and then to malignant SCC tumors. She is also investigating the critical downstream effectors of WNT signaling in this process, in order to identify improved targets for cancer therapeutics.
