Research Overview 1

Interaction of drug solution pretreated BMSCs with breast cancer cells

This research aims to investigate the effects of bone marrow-derived mesenchymal stem cells (BMSCs) that have been pretreated with drug solutions on human breast cancer cells. BMSCs pretreated with the drug solutions reduce the growth and proliferation rate of MCF-7, an effect that may be attributed to the reduction of FGF4 protein level in the pretreated BMSCs conditioned medium. The drug solutions pretreated BMSCs may have a potential application in stem cell?mediated therapy for human breast cancer and other malignancies.

Research Overview 2

Expression of multiple copy recombinant DNA topoisomerase gene in Pichia pastoris

This research describes the selection of clones containing multiple copy number gene for expression of human DNA topoisomerase in shaker flask system. DNA relaxation activity reveals that the target enzyme in the culture supernatants of GS115 exhibits consistent enzyme activity over the cultivation time-points. The enzyme produced can be used for affordable gel-based DNA relaxation assay development in performing high throughput screening for target-specific growth inhibitors. These inhibitors may contribute to the improvement of the treatment of cancer patients.

Research Overview 3

Fundamental study of infectious colorectal cancer

This research demonstrates that silencing IL-21 gene in HCT116 increase the cytotoxic level and FGF4 mRNA expression in the cancer cells. Gene silencing also reduces the aggressiveness of the cancer cells. Neutralizing FGF4 in conditioned medium of IL-21-silenced HCT116 further increase the cytotoxic level but restore the aggressiveness of HCT116. The results pave the knowledge for the discovery of important factors to be used as biomarkers for new drug design to effectively treat the patients having infectious diseases and colorectal cancer simultaneously.
