    RESEARCH INTERESTS

    Dr. Liou’s research interests focus on three areas: (1) Signal transduction pathways of cell differentiation and survival for mouse embryonic stem (mES) cells. He has recently discovered signal pathway to commit mouse embryonic stem cell differentiate into neural linage cells. (2) Mechanisms of cancer cell apoptosis and metastasis. Dr. Liou has identified several proteins and signals to control cancer cell migration and survival. (3) Molecular mechanism of endothelial cell survival.

    RESEARCH ACTIVITIES & ACCOMPLISHMENTS

    Dr. Liou has demonstrated that COX-2 derived PGE2 protects mES cells from apoptosis through EP2 and PI3K-Akt signal pathway. Further, he has shown multiple mechanisms of PGI2 which include PGI2 transcriptional up-regulates 14-3-3 via PPAR-dependent pathway, phosphorylates XIAP and induces eNOS expression through ERK to protect endothelial cell survival. He has also reported that mitochondrial COX-2 plays an important role for cancer cell survival. Dr. Liou has presented his studies in many international conferences.

    HONORS & AWARDS

  • Travel Award of the 8th American Society for Biochemistry and Molecular Biology (ASBMB) Annual Meeting.
