A Molecular Switch Controlling Self-Assembly of Protein Nanotubes Discovered
International collaborative research among South Korea, United States, and Israel research institutionsThe key to the treatment of cancer and brain disease mechanism The molecular switch that controls the self-assembly structure of the protein nanotubes, which plays crucial role in cell division and intracellular transport of materials, has been discovered. KAIST Bio and Brain Engineering Department’s Professor Myeong-Cheol Choi and Professor Chae-Yeon Song conducted the research, in collaboration with the University of California in Santa Barbara, U.S., and Hebrew University in Israel. The findings of the research were published in Nature Materials on the 19th. Microtubules are tube shaped and composed of protein that plays a key role in cell division, cytoskeleton, and intercellular material transport and is only 25nm in diameter (1/100,000 thickness of a human hair). Conventionally, cancer treatment focused on disrupting the formation of microtubules to suppress the division of cancer cells. In addition Alzheimer’s is known to be caused by the diminishing of structural integrity of microtubules responsible for intercellular material transport which leads to failure in signal transfer. The research team utilized synchrotron x-ray scattering and transmission electron microscope to analyze the self assemble structure of protein nanotubes to subnanometer accuracy. As a result, the microtubules were found to assemble into 25nm thickness tubules by stacking protein blocks 4 x 5 x 8nm in dimension. In the process, the research team discovered the molecular switch that controls the shape of these protein blocks. In addition the research team was successful in creating a new protein tube structure. Professor Choi commented that they were successful in introducing a new paradigm that suggests the possibility of controlling the complex biological functions of human’s biological system with the simple use of physical principles. He commented further that it is anticipated that the findings will allow for the application of bio nanotubes in engineering and that this is a small step in finding the mechanism behind cancer treatment and neural diseases.

Is it possible to identify rumors on SNS?
Rumors sporadically spread with people with fewer followers in the centerResearched over 100 rumors in the US from 2006 to 2009 Is it possible to filter information on SNS such as Twitter and Facebook? A research team led by Professor Mee-Young Cha from the Department of Cultural Technology Graduate School at KAIST, Professor Kyo-Min Jung of Seoul National University, Doctor Wei Chen and Yajun Wang of Microsoft Asia, has developed a technology that can accurately filter out information on Twitter to 90% accuracy. The research not only deduced a new mathematical model, network structure, and linguistic characteristics on rumors from SNS data, but is also expected to enhance the effort to make secure technology to regulate Internet rumors. The team analysed the characteristics of rumors in over 100 widespread cases in the US from 2006 to 2009 on Twitter. The team gathered data, which included a range of areas such as politics, IT, health and celebrity gossips, and their analysis could identify rumors to 90% accuracy. The filtering was more accurate in rumors that included slanders or insults. The research team identified three characteristics of the spread of rumors. Firstly, rumors spread continuously. Normal news spreads widely once and is mentioned rarely again on media, but rumors tend to continue for years. Secondly, rumors spread through sporadic participation of random users with no connections. Rumors start from people with fewer followers and spread to the more popular. This phenomenon is often observed in rumors concerning celebrities or politicians. Lastly, rumors have unique linguistic characteristics. Rumors frequently include words (such as “it may be true,” “although not certain, I think,” “although I cannot fully remember”) related to psychological processes that question, deny, or infer the reliability of the information. Professor Cha said, “This research deduced not only a statistical and mathematical model but also is an integrated research on social psychological theory on the characteristics of rumors that attract great attention from the society based on ample data.” The results were made public in IEEE International Conference on Data Mining last December in Texas, USA.

Professor Suk-Bok Chang receives 14th Korea Science Award in the field of Chemistry
Professor Suk-Bok Chang from the Department of Chemistry at KAIST received the “2013 Korea Science Award” in chemistry hosted by the National Research Foundation and the Ministry of Science, ICT, and Future Planning, Republic of Korea. The Korea Science Award is a presidential award of Korea, which was first established in 1987 to recognize research excellence in natural science. Three scientists are selected for the award in every other year. Professor Chang primarily researches the catalyzing mechanism of carbon-hydrogen bonds in organic molecules. He has succeeded in making great progress in the field of organic chemistry especially in developing a new type of transition metal catalytic behavior that can be applied to low-reactivity compounds. Hydrocarbons are abundant in nature, but its unreactive nature in ambient conditions makes it unsuitable as reactant for compound synthesis. In addition, the mechanism behind transition metal catalyzed carbon-hydrogen bond synthesis has not been proven sufficiently. The prediction that fossil fuels will be depleted before the end of the century makes hydrocarbon synthesis an extremely important matter. The need for an effective hydrocarbon synthesis method inspired Professor Chang to pursue research in the transition metal catalysis method and to develop a catalytic system that would allow efficient synthesis even in ambient conditions. Professor Chang has been the lead researcher for the Institute for Basic Science’s “molecule catalysis reaction research team” since December 2012 and has been carrying out this research in KAIST.

Mechanism in regulation of cancer-related key enzyme, ATM, for DNA damage and repair revealed
Professor Kwang-Wook Choi A research team led by Professor Kwang-Wook Choi and Dr. Seong-Tae Hong from the Department of Biological Sciences at KAIST has successfully investigated the operational mechanism of the protein Ataxia Telangiectasia Mutated (ATM), an essential protein to the function of a crucial key enzyme that repairs the damaged DNA which stores biometric information. The results were published on December 19th Nature Communications online edition. All organisms, including humans, constantly strive to protect the information within their DNA from damages posed by a number of factors, such as carbonized materials in our daily food intake, radioactive materials such as radon emitting from the cement of buildings or ultraviolet of the sunlight, which could be a trigger for cancer. In order to keep the DNA information safe, the organisms are always carrying out complex and sophisticated DNA repair work, which involves the crucial DNA damage repair protein ATM. Consequently, a faulty ATM leads to higher risks of cancer. Until now, academia predicted that the Translationally Controlled Tumor Protein (TCTP) will play an important role in regulating the function of ATM. However, since most of main research regarding TCTP has only been conducted in cultured cells, it was unable to identify exactly what mechanisms TCTP employs to control ATM. The KAIST research team identified that TCTP can combine with ATM or increase the enzymatic activity of ATM. In addition, Drosophilia, one of the most widely used model organisms for molecular genetics, has been used to identify that TCTP and ATM play a very important role in repairing the DNA damaged by radiation. This information has allowed the researchers to establish TCTP’s essential function in maintaining the DNA information in cell cultures and even in higher organisms, and to provide specific and important clues to the regulation of ATM by TCTP. Professor Kwang-Wook Choi said, “Our research is a good example that basic research using Drosophilia can make important contributions to understanding the process of diseases, such as cancer, and to developing adequate treatment.” The research has been funded by the Ministry of Science, ICT and Future Planning, Republic of Korea, and the National Research Foundation of Korea. Figure 1. When the amount of TCTP protein is reduced, cells of the Drosophila's eye are abnormally deformed by radiation. Scale bars = 200mm Figure 2. When the amount of TCTP protein is reduced, the chromosomes of Drosophilia are easily broken by radiation. Scale bars = 10 mm. Figure 3. When gene expressions of TCTP and ATM are reduced, large defects occur in the normal development of the eye. (Left: normal Drosophilia's eye, right: development-deficient eye) Figure 4. ATM marks the position of the broken DNA, with TCTP helping to facilitate this reaction. DNA (blue line) within the cell nucleus is coiled around the histone protein (green cylinder). When DNA is broken, ATM protein attaches a phosphate group (P). Multiple DNA repair protein recognizes the phosphate as a signal that requires repair and gathers at the site.
