Introduction
In the Department of Analytical Pathology, the pathobiological and clinicopathological characteristics of the target molecules are analyzed for evaluating their potential significance in applying diagnostic or treatment use in future. Expression of the molecules or genes in human tissues is assessed by morphological techniques, immunohistochemistry, RT-PCR, in situ hybridization, etc., and the results are compared to clinicopathological information. We also aim to develop new, more reliable, or more effective analytical methods and tools.
Research activities
Tumor immune microenvironment in pancreatic cancer is studied clinicopathologically and pathobiologically. Tumor infiltrating lymphocytes move from the regional lymph nodes to the tumor tissue via blood stream. Endothelial cells support extravasation of lymphocytes. We have found that endothelial cells in the cancer tissue have dysfunctional expressions of adhesion molecules resulting in decrement of tumor-infiltrating lymphocytes. This dysfunction is caused by abnormal TNFR1 signaling. We have identified novel compounds that can modulate TNFR1 signaling and promote tumor-infiltrating lymphocytes, thereby enhancing the antitumor immune response (Fig 1). We have also reported the clinicopathological significance of both classical and non-classical HLA class I antigens for pancreatic cancer.
Education
We taught analytical techniques to technicians and researchers in several departments of the National Cancer Center.
Future Prospects
We will answer the requests from the selected project in various types of study containing basic, preclinical, and clinical studies, and assess the clinicopathological or pathobiological significance of the target molecules. We will develop methods of quantitative analysis to evaluate morphological findings that are currently analyzed qualitatively.
