Prof. Dr. Je-Yong Choi is a Professor at the Department of Medicine, Kyungpook National University. He completed his PhD studies in Biochemistry at Kyungpook National University in 1994. His research interests include osteoarthritis; osteoporosis; vascular calcification; bone cell biology; biomineralization; Runx/Cbfb transcription factors; and mouse genetics. In addition, His Major Research Achievements include (1) Identifying essential roles for Cbfb in osteoblast formation and chondrocyte maturation by Runx2 and in articular chondrocyte maintenance by Runx1; (2) exploring various biological applications of 4-Hexylresorcinol, including anticancer, anti-inflammatory, and biocompatibility enhancing functions; (3) establishing a mouse vascular calcification (VC) model using high dose vitamin D and identifying the essential role of Runx2 and VDR in VC; and (4) discovering the essential role of the Runx2 carboxyl terminus for subnuclear targeting, osteoblast formation, and chondrocyte maturation during skeletal
