RESEARCH INTERESTS

Dr. Huang's research team has recently focused on the studies of cancer proteomics and tumor-associated macrophages. They have been exploiting the strategies of proteomics to investigate the cancer protein alterations and studying their possible clinical relevance to cancer metastasis and poor prognosis. Additionally, they have learned that solid tumor is not only composed of tumor cells, rather, it comprises a range of stromal cells including fibroblasts and macrophages. They are paying much attention on the interaction between tumor cells and tumor-associated macrophages.

RESEARCH ACTIVITIES & ACCOMPLISHMENTS

Recently, they have used 2D-DIGE and MALDI-TOF to identify beta-1,4- galactosyltransferase-IV differentially expressed in the tumor tissue and its adjacent non-tumor tissue of a colorectal cancer patient. By using a novel tissue lysis method and immunoblot analyses, they noted that 28% of colon cancer patients exhibited tumor beta-1,4-galactosyltransferase-IV overexpression, which was able to serve as an independent factor to predict cancer metastasis and shorter survival. On the other hand, they have successfully used an in vitro Matrigel system to prove the stimulatory effect of macrophages on the angiogenic activity of cancer cells. Interleukin-6 was first time indicated to participate in macrophage-involving tumor angiogenesis. In addition, they have found that ET-ETR axes and uPA-integrin interaction are also involved in transendothelial migration and cancer metastasis induced by tumorassociated macrophages.
