Scientific Interests

Dr. Arnold Chin's Laboratory is dedicated to improving the lives of patients with urologic malignancies. Much of their initial studies have focused on understanding the molecular pathways that program the tumor infiltrating lymphocytes in bladder and prostate cancer, which they have shown can influence tumor growth, ability to metastasize and response to immune-based therapies. More recently, they began studying the characteristics and drivers of bladder cancer stem cells.

Chin's laboratory currently studies two main areas:

  1. They have identified an alternatively spliced form of a transcription factor, FOXP3, that activates and makes bladder cancer stem cells more aggressive. They will exploit this observation by understanding its basic biology and develop novel inhibitors of FOXP3.
  2. They are characterizing the tumor population in micrometastatic lymph nodes, which they hypothesize is enriched in a cancer stem cell population. Identifying this population will improve pathologic staging as well provide therapeutic insight into inhibiting the process of metastases.
