biorhythm+mechanism

'Scientist-Engineer of the Month' for December: Professor Choi Joon Ho Professor Choi Joon Ho (department of Biological Sciences) was made ‘Scientist-Engineer of December’ for his discovery of new gene (twenty-four) that helps biorhythm and proving that this gene helps control biorhythm. Professor Choi published 100 dissertations over the past 25 years and made significant advancements in the field of molecular virus and neurobiology. In 1995 Professor Choi uncovered the fact that the NS3 protein in C type hepatitis function as RNA helicase thereby opening the path to developing a cure for C type hepatitis; this is an international patent with Chiron corporation. The result was published in Biochemical and Biophysical Research Communications Journal and was the most domestically referred to dissertation in biological sciences in 1999. In addition Professor Choi published in Nature magazine in 1999, a dissertation that uncovered the fact that the DNA of papillomar virus has another protein (hSNF5) that direct it apart from ordinary proteins. In 2000~2005 Professor Choi published many dissertations in journals like Immunity, Cancer Research, Molecular and Cellular Biology, Oncogene, Journal of Virology, and etc. Professor Choi screened over 10,000 species of pomace fly mutations and discovered the twenty-four gene that affects the biorhythm of pomace flies. He analyzed this gene further and found a new function that was different from known biorhythm mechanisms. This research allowed a better understanding of biological clock of pomace flies and therefore was another step towards better understanding the control mechanism of human biological clock.
