Gene Protecting Brain Nerves Discovered
THE KOREA TIMES 2005.1.31By Kim Tae-gyu / Staff Reporter
South Korean scientists have for the first time discovered genes tasked with protecting brain nerves.
Korea Advanced Institute of Science and Technology professor Kim Jae-seob said Sunday the new genes, named pyrexia, shield brain nerves from outside stimuli, including high temperatures.
``The channel gene of pyrexia will open the door to developing new-concept medicines for brain damage in patients of high fever or drug addicts,’’ he said.
The channel gene refers to transport proteins, which provide a static passageway for a variety of essential substances to enter into cells.
``Up until now, a lot of channel genes activated by temperatures have been identified. But among them, pyrexia is first that guards brain nerves from external stresses,’’ Kim said.
Kim’s team learned pyrexia plays a pivotal role in the body through experiments with genetically engineered flies that did not have any pyrexia.
Up to 60 percent of the pyrexia-depleted mutants were paralyzed within three minutes of exposure to a temperature of 40 degrees Celsius.
In comparison, just 9 percent of normal flies were paralyzed with the same stimulus, indicating pyrexia is responsible for protecting animals from high-temperature stress.
``Our next goal is to develop pyrexia-embedded drugs, which can be expected to commercially debut in about five years,’’ Kim said.
Kim has already applied for international patents for his medical breakthrough, which will be printed in the March edition of Nature Genetics, a science journal.

Nerve-protecting gene discovered
Korean scientists for the first time have identified a gene that blocks nerve damage from fevers and the use of narcotics, a state-run research institute said yesterday.
The finding may open the way for new medicine that can prevent the loss of brain function which is frequently caused by excessive stimulation of nerves and abnormally high body temperature.
"The research is in an early stage. But this approach has the potential to develop genetics-based preventatives against brain-attacking diseases," said Kim Jae-seob, a bioscience professor of the Korea Advanced Institute of Science and Technology, who led the study.
The researchers named the gene Pyrexia, which means fever. Kim"s team extracted it from genetically engineered fruit flies using a genome-screening system. In laboratory tests, they found that the gene is activated to 39 degrees Celsius or higher.
The researchers enhanced Pyrexia"s functionality in some fruit flies while removing the gene from others to observe their different reactions when exposed to high temperature.
"The fruit flies without the gene showed severe nerve disorder and suffered paralysis of brain function, while Pyrexia-enhanced flies maintained their normal brain conditions," the professor said.
The researchers got the same result from experiments with human cells, he said.
There are a lot of channel proteins, which enable ions to enter and exit the cell, that react to the level of temperature, but Pyrexia is the first of its kind that actually protects the neurons from external stimulus, he said.
The finding will appear on the March edition of the London-based science magazine Nature Genetics.

Nobel Laureate Heads KAIST
Nobel Laureate Heads KAIST
By Kim Tae-gyu / Staff Reporter
THE KOREA TIMES 05-29-2004
A Nobel laureate will lead the Korea Advanced Institute of Science and Technology (KAIST), winning a stiff race with a pair of strong Korean candidates.
The KAIST on Friday said the state-financed institute appointed Robert Laughlin as its 12th president instead of two local hopefuls, professors Shin Seong-cheol and Park Seong-ju.
This is the first time that foreigners take charge of the KAIST since it was established in 1971 and Laughlin also is noted in the history as the first Nobel Prize winner to head Korea"s educational institute.
After receiving approval of Science-Technology Minister Oh Myung, Laughlin will be inaugurated as early as next month, according to a KAIST official.
Laughlin, a Stanford professor, made his name after being co-awarded the 1998 Nobel Prize in Physics with Horst Stoermer and Daniel Tsui for the discovery of a new form of quantum fluid.
The findings, which explained the fractional quantum hall effect for the first time, have been recognized as a significant breakthrough in understanding quantum physics.
The American physicist had also sustained a special connection with Korea even before he garnered the prestigious prize and has visited Korea several times.
Early last month, Laughlin was named to head the Asia Pacific Center for Theoretical Physics (APCTP) in recognition of his notable interest in Korea.
The APCTP is an international research institute headquartered inside Pohang University of Science and Technology in North Kyongsang Province.

Professor Kim Donates W5 Bil. to KAIST
Korea Times 2004.5.21
By Kim Tae-gyu / Staff Reporter
A professor from the Korea Advanced Institute of Science and Technology (KAIST) has donated his inherited wealth of 5 billion won to the state-owned institute.
The KAIST announced professor Kim Dong-won contributed 5 billion won in properties and cash, which he inherited from his father, who passed away late last year.
``Professor Kim has asked us to spend the contribution in the development of Korea’s science in accordance with the late Kim’s will,’’ said Park Jae-wook, a KAIST spokesman.
Park added Kim had tried to remain anonymous, but his identity was revealed by some local newspapers. Kim is currently in the United States as he is out of his post on an interim basis and will come back to Korea in August.
Four billion won of the donation will be used to set up scholarships, which will endow 20 million won each to 10 KAIST students every year. The remaining 1 billion won will help invite illustrious scholars to the institute.
Adding to the good news for KAIST, Lee Chong-moon, chairman of the U.S.-based venture company Ambex, has also donated 2 billion won.
The 76-year-old Lee called for the KAIST to inspire a sprit among students by establishing a management center named after him.

18th Student Council Elected
The KAIST Herald December 3, 2003
The votes were cast and counted on November 27. Donggodongrak won the election of the 18th Undergraduage Student Council of Korea Advanced Institute of Science and Technology (KAIST). Of the 2,340 eligible voters for the 18th student council election, 1,304 votes, or about 56 percent of the total, were amassed after a full day of election on November 27.
The two candidate teams, waiting to hear the result with much anxiety, were juniors Hye-min Kim and Jung-mo Kim running for the president and vice president positions, respectively, of the team "Donggodongrak" and juniors Dong-geun Kim and Yong-jae Yoon running for the same positions, respectively under the name "Woorung Chonggak."
Donggodongrak secured over 58 percent of the votes, with 760 supporting ballots, while Woorung Chongak polled 503 votes, or about 39 percent of the votes. Forty-one votes, or three percent of the votes cast were spoiled votes. With more than half the voters having participated, the election was valid, and Donggodongrak was declared the new student council of KAIST.
The election platform of the Donggodongrak team largely consist of four themes, composed of several smaller goals. First, they assert the "togetherness" of the student government and plan to achieve it by publishing monthly newsletters, hosting an open outdoor student council every other week, and creating various committees.
Secondly, they assert under the theme of an "improving" student government that they will promote festivals and events among the sixteen departments, form an official "class" of the freshmen, and broaden the association of the student representatives.
Third, Donggodongrak declares it wants to create an "open and just environment" by holding periodic meetings with the school for direct discussions of school policies; and by taking care of the welfare of the students in detail.
Finally, they advocate "a student government that communicates with society"; they will support opportunities to become more aware of various issues of society.
President Hye-min Kim, a graduate of Pusan Science High School, has participated in various intramural, socially active groups, and is majoring in applied mathematics. Vice-president Jung-mo Kim is a graduate of Mokpo High School and studies mechanical engineering.

Researchers Find Mechanism of Tumor Suppressor Genes
By Kim Tae-gyu. Staff ReporterTHE Korea Times 02-06-2004
Korean scientists continue to break new ground in fighting cancer as domestic researchers examined the mechanism of a gene which can help detect and treat various sorts of cancer.
Korea Advanced Institute of Science and Technology (KAIST) Prof. Lim Dae-sik on Thursday said his team uncovered the mechanism of RASSF1A (Ras Association Domain Family 1 A), or tumor suppressor genes, for the first time in the world.
The gene was widely considered to play an important role in reducing the proliferation of cancer cells, but its exact function and processes have remained unknown up to now.
It is the second cancer-related breakthrough by Koreans in a week after Korea Institute of Science and Technology (KIST) Prof. Chung Hesson unveiled the oral anti-cancer drug.
``Cancer results from the failed management of cell cycles due to things like radiation. After a two-year intensive study, we found out how RASSF1A governs the cell cycle,"" Lim said.
Lim added cancer is caused by abnormal cells, which continue to grow and divide out of control unlike normal cells, which die over time. Cancer cells develop into malignant tumors, eventually inflicting damaging effect on the human body.
As a result, a lack of the RASSF1A indicates a high possibility of cancer and injection of it into cells is believed to help cure the deadly disease, according to Lim.
Dr. Song Min-sup, who took charge of the research, said the findings will especially pave the way for the detection and treatment of lung cancer.
``The dearth of RASSF1A was reported mostly in the case of lung cancer. The new findings will provide insight into the diagnosis and cure of lung cancer from its early stages,"" Song explained.
Lung cancer is a very elusive disease because it doesn"t cause symptoms in its infancy. When symptoms do occur, usually it is too late.
``We expect commercial detection kits or drugs for lung cancer in around five years after pre-clinic experimentation and two-phase clinic trials,"" Song expected.
Details of the study is available in the scientific journal Nature Cell Biology in its February edition.
