RESEARCH INTERESTSDr. Shih's research is mainly focused on how tumor cells escape from the immune attack and what the molecular mechanisms mediated by the tumor cells are. Three major research directions are undergoing in his lab: (1) cloning of genes encoding “immunogenic” tumor-associated antigens (TAAs), those are recognized by immune cells, from patients with lung or ovarian cancer; (2) functional studies of those TAAs in tumor cells and in tumor surveillance, primarily, focused on how tumor cells mediate TAAs to induce immune suppression or tolerance; (3) therapeutic effects of the TAAs in tumor prevention and eradication. In addition, his lab is also interested in functional dysregulation of cytotoxic T lymphocytes (Tc) and T regulator (Treg) in cancer patients by examining activation status of signaling molecules. Currently, several tumor-associated genes have been identified and characterized as novel clinical prognostic and diagnostic markers for lung and ovarian cancers. Results from molecular dissection of several TAAs functioning in tumor cells also strongly supports their roles on tumor malignancy. Using those TAAs as vaccine antigens in animal model, his lab preliminarily conformed their therapeutic effects on tumor prevention and eradication.
RESEARCH ACTIVITIES & ACCOMPLISHMENTSDr. Shih has successfully cloned and identified several genes coding for immunogenic tumor-associated antigens using either a combination of biochemical purification and mass spectrometric analyses or peptide-displaying system. Expression statuses of those antigens have been confirmed to be tightly associated with clinical outcomes, including total disease-free and metastasis-free survivals, in patients with either lung or ovarian cancer. They also further characterized the cellular functions of these antigens in tumor cells. For instance, overexpression of the p48ENO1 gene in noninvasive cells could significantly increase cell migration and enhance lung metastasis in animals. The molecular mechanisms associated with this biological behavior are mediated by upregulation of some chemokines and cytoskeleton proteins in the cells. Intriguingly, using P48ENO1 as a target of immune attack, they successfully demonstrated that induction of anti-ENO1 immunity was sufficient to prevent and suppress tumor growth in immunocompetent mice. This work has been filed US and Taiwan patents and published in an international journal. Additionally, this funding can provide not only alternative cancer treatment for cancer patients, but also a novel potential tumor marker for prognosis of lung cancer.
