Publication number: 20200377862Abstract: The present disclosure relates to a cancer cell line having a stem cellularity and a method for producing the same, and more specifically, to inducing cancer cells to cancer stem cells by applying metabolic stress. More specifically, the present disclosures relates to the production and establishment of the cancer stem cell by repeating culturing in a glucose-deficient medium. The main features of the cancer stem cell produced by the method are that, in a glucose-deficient environment, the resistance to apoptosis is exhibited high and the resistance to anticancer drugs is highly exhibited high.Type: ApplicationFiled: April 20, 2018Publication date: December 3, 2020Applicant: YOUNSEI UNIVERSITY INDUSTRY FOUNDATIONInventors: Jaemoon YANG, Jin-Suck SUH, Minhee KU

Patent number: 10144806Abstract: Provided are polyaniline coordinated with a transition metal, a core-shell nanoparticle including the same as a core, and preparation methods thereof. According to the polyaniline coordinated with a transition metal and the nanoparticle of the present application, it is possible to prepare polyaniline coordinated with a transition metal using an oxidizing agent having a core-shell structure and including the transition metal and a nanoparticle including the same as a core. The polyaniline prepared as such is in a doped state, and, thus, a preparation process is simple. Further, dispersibility with respect to a solvent is improved, and a band gap level of the polyaniline can be easily regulated.Type: GrantFiled: March 3, 2015Date of Patent: December 4, 2018Assignee: University-Industry Foundation, Yonsei UniversityInventors: Seungjoo Haam, Yong-min Huh, Jaemoon Yang, Jihye Choi, Eun Bi Choi, Seo Ryung Bae, Byunghoon Kang, Myeong-Hoon Kim, Yoochan Hong, Hyun-Ouk Kim
