A mechanism for how reactive oxygen species cause cell responses studied
A research team led by Professor Kwang-Hyun Cho of the Department of Biology and Brain Engineering, KAIST, and Dr. Gi-Sun Kwon of the Korea Research Institute of Bioscience and Biotechnology succeeded in proving the mechanism behind the determination of cell life in relation to reactive oxygen species. The results of the venture were published in the June 3rd edition of Science Signaling. The title of the research paper is “MLK3 is part of a feedback mechanism that regulates different cellular responses to reactive oxygen species.” The research team discovered that the molecular switch that determines the division of apoptosis of a cell was based on MLK3 feedback mechanism. MLK stands for mixed-lineage kinase. Under sufficient stress, the mechanism instructs the cell to undergo the division but in an overly stressful environment, the mechanism stops the cell division and instead, induces apoptosis. This discovery is expected to be a breakthrough in illnesses related to the concentration of the reactive oxygen species (ROS). At low concentration of ROS, the protein associated with cell division, ERK (extracellular-signal-regulated kinase), is activated while as the ROS concentration increases, JNK (c-Jun N-terminal protein kinases), responsible for apoptosis, becomes activated. Furthermore, through computer simulation analysis and mathematical modeling, in tandem with molecular cell biology experiments, the MLK3 based feedback mechanism was the fundamental molecular switch that determines the balance between ERK and JNK, and ultimately the cell’s responses. Professor Cho commented that “the contradicting cell responses to ROS had remained a mystery, but with the system biology, an approach in which information technology and biotechnology converge, such riddles can be resolved. We expect that the proven mechanism will be used to overcome aging or cancer growth as a result of ROS in the near future.” Picture shows the process of identifying cell responses caused by reactive oxygen species.

An Exploratory Study on Smartphone Abuse among College Students
Professor Uichin Lee Professor Uichin Lee of the Department of Knowledge Service Engineering, KAIST, and his research team developed a system that automatically diagnoses the levels of smartphone addiction based on an analysis of smartphone use records. Professor Lee investigated the usage patterns of 95 smartphone users (college students) by conducting surveys and interviews and collecting logged data. The research team divided participants into “risk” and “non-risk” groups based on a self-reported rating scale to evaluate their abuse of smartphones. As a result, 36 students were categorized as “high risk” and 59 were categorized as “low risk.” The researchers collected over 50,000 hours of smartphone use encompassing power levels, screen, battery status, application use, internet use, calling, and texting. The results showed that the “high risk” group used only 1~2 applications, focusing on mobile messengers (Kakotalk, etc.) and SNS (Facebook, etc.). In addition, a relationship was found between alarm function and addiction levels. Users who set alarms for Kakaotalk messages and SNS comments used smartphones for an additional 38 minutes per day on average. Results also showed that “high risk” students were on their smartphones for 4 hours and 13 minutes per day, 46 minutes longer than “low risk” students who used smartphones for 3 hours and 27 minutes. The difference was prevalent during 6 am and noon, and 6pm and midnight. In addition, “high risk” students accessed their smartphones 11.4 times more than “low risk” students. Based on the collected data, Professor Lee developed an automatic system that distinguished users into “high risk” or “low risk” categories with 80% accuracy. The new system is expected to give an early diagnosis of addiction to smartphone users, thereby allowing for early treatment and intervention before the user becomes addicted. Professor Lee commented that, "the conventional addiction analysis based on self-analysis surveys did not provide real-time data and were largely inaccurate. The new system overcomes these limitations through data science and personal big data analysis" and that he is "developing an application that monitors smartphone abuse." Figure 1.

Immune Evasion Mechanism of Hepatitis C Virus Revealed
Professor Ui-Cheol Shin Inhibiting major histocompatibility complex [MHC] class I protein expression, T cell immune response is evaded. The research will be a great help to the development of C hepatitis vaccine. Roughly 1-2% of the population in Korea is known to be infected with Hepatitis C. Most Hepatitis C Virus (HCV) infections progress to a chronic disease and can cause liver cirrhosis or liver cancer, which may lead to death. Unlike Hepatitis type A or B, there is no vaccine for Hepatitis C Virus and therefore avoiding exposure to the virus is the best known method of prevention. However, a team of researchers at KAIST has produced research results, which may contribute significantly to the vaccine development. KAIST Graduate School of Medical Sciences & Engineering’ Professor Ui-Cheol Shin and his team have successfully identified why Hepatitis C Virus does not cause an immune response within the human body. The research results were published in the May edition of The Journal of Gastroenterology, a world-renowned journal in the field of gastroenterology. The immune response occurs to eliminate the virus that has invaded our body. During this process, a major histocompatibility complex [MHC] class I plays a key role in inducing T cell response, which is needed for the elimination of virus-infected cells. When a cell is infected by a virus, a substance called interferon causes the increased expression of major histocompatibility complex class I. T cell recognizes the increased MHC class I and therefore finds the virus-infected cells. However, the effect that Hepatitis C Virus has on major histocompatibility complex class I has not been clearly identified until now. The research team has revealed, using a cell culture for infection systems, that the Hepatitis C Virus suppresses the expression of major histocompatibility complex class I. Also, the mechanism to prove that HCV activates a protein called PKR within the cell to inhibit MHC class I protein expression was identified at a molecular level. In this study, researchers established the hypothesis that regulating PKR protein in the cell can enhance the T cell immune response, which was then proved through experiments. Professor Ui-Cheol Shin said, “There are a lot of new drugs to treat Hepatitis C Virus, while its vaccine has not been developed yet. Revealing the HCV immune evasion mechanism will help stimulate momentum for the HCV vaccine development.” The first author of the journal, Dr. Won-Seok Kang is a graduate from Yonsei College of Medicine. After earning his medical degree, he has continued his training as a ‘doctor-scientist’ at KAIST Graduate School of Medical Sciences & Engineering to study Hepatitis C Virus immune evasion mechanism in this research. Hepatitis C Virus activates PKR-eIF2a pathway, which inhibits the major histocompatibility complex class I, and therefore weakens the T cell activation to the viral activity.
