POSTECH Scientists Research RNA Polymerase Contribution to Gene Expression, Published in Nature Communications

Noise plays a key role in important biological processes, such as bacterial antibiotics resistance, cancer development, and stem cell differentiation. Physics can explain much of this biological phenomenon. Professor Nam Ki Lee of the Department of Physics and the School of Interdisciplinary Bioscience and Bioengineering with Department of Physics graduate students Sora Yang, Seunghyeon Kim, Cheolhee Kim, Hyeong Jeon An and Professor Jaeyoung Sung of Chung-Ang University studied how cells propagate noise using RNA polymerase. Their research was published in this month’s Nature Communica..

Prof. Yoon-Seok Chang Wins Korean Society of Environmental Engineers Academic Research Award

Professor Yoon-Seok Chang (School of Environmental Science and Engineering), a worldwide authority on dioxin, has been selected as a first prize winner of the academic research award by the Korean Society of Environmental Engineers. An awards ceremony was held at the Kimdaejung Convention Center on August 21st. Over the past 30 years, Professor Chang has published nearly 200 SCI papers and studies which include analyses of toxic substances such as dioxins and other endocrine on human health. His study of the environmental risks of bio-nanomaterials has recently received academic attention.

Professor Hyung Joon Cha on Bone Regeneration Enhanced by Use of Mussel Adhesive Proteins

POSTECH Department of Chemical Engineering Professor Hyung Joon Cha and his team’s research on bone graft material binder technology was published in the Journal of Materials Chemistry B.Mussels stick to rocks because its protein has strong adhesive properties. This protein has been used as a binder for bodily wounds and surgery. An engineered mussel glue protein,a promising functional binder for the acceleration of bone substitute-assisted bone regeneration,has been developed by the joint research team of POSTECH and Korea University Anam Hospital, which can be used in teeth implants. ..

Generated Cells a Scientific Breakthrough for RNA Therapeutic Research

The research team of Professors Jaesung Park (Department of Mechanical Engineering) and Yong Song Gho (Department of Life Sciences) has developed a way to generate artificial nanovesicles that can be used to deliver RNA, a breakthrough that is expected to be used in exosomes research and to have applications in drug and RNA-delivery systems. Their paper, "Microfluidicfabrication of cell-derived nanovesicles as endogenous RNA carriers”,made it onto the cover of the journalLab on a Chipand was selected as a Hot Article. Exosomes/microvesicles are known to shuttle biological signals..

Professors Develop Customized 3D Printed Implant for Facial Reconstruction

Despite having numerous advantages, clinical applications of 3D printed scaffolds for tissue regeneration are extremely rare. A team consisting of POSTECH Professor of Mechanical Engineering Dong-Woo Cho, Professor Jong Won Rhie of the Department of Plastic Surgery College of Medicine at the Catholic University of Korea, and Won-Soo Yun of T&R Biofab Co., have applied 3D printing technology for correcting an asymmetric face caused by the removal of a tumor in a patient about a decade ago.The patient had trauma in the right malar region and because of this his eyes were misaligned. In this ..

Scientists at GIFT Develop a New Theory for Plasticity of Face-Centered Cubic Metals

The fundamental concepts of physics are crucial to understanding the correlation of the structure and strength of materials. Some materials, like a steel coil spring or rubber, are elastic. Grasping a rubber ball deforms the shape momentarily before it returns to its original state. Other materials when manipulated with, such as clay, will retain its newly deformed shape. This phenomenon, called plasticity, has been studied by scientists in designing high strength steels and alloys. The demand for high-technology metallic materials continues to depend on further research and understanding of ..

New Research Shows How Cholesterol Can Lead to Cancer

POSTECH researchers have found another reason to cut down on a high-fat and cholesterol diet. Their findings show that cholesterol is crucial for Wnt signaling pathway often linked to human birth defects, cancer, and other diseases. Research groups of Prof. Jin-Kwan Han in the Department of Life Sciences at POSTECH and Prof. Wonhwa Cho from the University of Illinois at Chicago performed this study. Their research was published in the July edition of Nature Communications. Wnt signaling processes biological functions through ‘canonical’ and ‘non-canonical’ pathways..

POSTECH Scientists Develop a New Treatment for Rheumatoid Arthritis

A research team, led by Department of Materials Science and Engineering Associate Professor Sei Kwang Hahn and graduate student Hwiwon Lee, has published research on a new rheumatoid arthritis treatment. The article “Hyaluronate – Gold Nanoparticle/Tocilizumab Complex for the Treatment of Rheumatoid Arthritis” was published in the April 2014 edition of the ACS Nano, a monthly scientific journal published by the American Chemical Society. Rheumatoid arthritis (RA) is a chronic inflammatory immune disease that affects 0.5 to 1 percent of the adult population worldwide and ..

Revolutionizing Organ Development: POSTECH Researchers Develop Novel 3D Bioprinting Process

Professor Dong-Woo Cho’s team at POSTECH is engaged in the development of novel tissue and organ printing technology that can bridge that gap that currently exists between the supply and demand of tissues and organs for patients suffering from tissue loss or organ failure. This novel tissue printing technology could lead to the regeneration of healthy functional tissues or organs for patients, thus, eliminating the need for tissue grafts and mechanical devices. The POSETCH team made up of Falguni Pati, Jinah Jang, and Dong-Heon Ha, recently published their findings in an article entitle..
