Research Interests

Current research mainly focus on acid ceramidase (ACDase), a lysosomal enzyme, causes degradation of Ceramide (Cer) into sphingosine (Sph) and free fatty acids at pH optimum 4.5. ACDase represents a new target for cancer therapy because of its importance in regulating the Cer–Sph–S1P inter-metabolism. Elevation of ACDase was shown in many tumor tissues when compared with patient’s matched normal ones. ACDase can also be over-expressed in prostate cancer cells after a single, low-dose of ionizing radiation, raising speculation about the correlation of increased ACDase to radio-resistance, and the potential of ACDase inhibition being a therapeutic strategy for treating cancer.
