五、研究方向:
One of my research plans is to study the etiology of spinal muscular atrophy (SMA) and to search for effective medication for the disease. SMA is an autosomal recessive genetic disease affecting motor neuron integrity. The motor neurons influence the voluntary muscles that are used for activities such as crawling, walking, and head and neck control etc. Individuals with SMA generally do not have a functional SMN1 (survival motor neuron 1) gene that produces SMN protein required for functional motor neurons. It is estimated that approximately 50 infants are the victims of SMA annually in Taiwan. However, there is no an effective drug to cure or postpone the onset of the disease. One of my research projects is to screen drugs or chemicals that are capable of altering the splicing pattern of SMN1 gene, the isoform of its products playing a critical role on the severity of spinal muscular atrophy (SMA).

The other long-term objective of my research is to understand the mechanisms involved in protein sorting at sites in the endoplasmic reticulum (ER) membrane. One of my current works is to identify and characterize the mechanisms that accomplish and regulate the co-translational translocation and integration of proteins on ER. We utilize a chemical procedure for attaching a probe to the amino group on the lysine side-chain of Lys-tRNA. The fluororecent aa-tRNA analog was incorporated into newly synthesized peptide during in vitro translation, therefore provided a unique mechanism for inserting probes into the nascent chain of proteins. Several fluorescence characteristics and techniques such as fluorescence resonance energy transfer (FRET), collisional quenching, fluorescence life-time, anisotropy (or polarity), and the sensitivity of fluorescence intensity to its environment are all used in this study.
