Patent number: 10973884Abstract: The present invention relates to a pharmaceutical composition for treating cancer, containing cytochrome b5 reductase 3 (CYB5R3) protein as an active ingredient. Over-expression of CYB5R3 in cancer cells results in significant reduction of hypoxia-inducible factor-1? (HIF-1?) expression, which leads inhibition of cancer cells growth in vitro and in vivo. Thus, the CYB5R3 gene or protein of the present invention can be useful as an active ingredient of a pharmaceutical composition for treating cancer.Type: GrantFiled: March 31, 2016Date of Patent: April 13, 2021Inventors: Mi Sun Won, Hyun Seung Ban, Bo Kyung Kim, Soon Woo Nam, Kyeong Lee, Young-Ju Lee, Hong-Sub Lee, Dong Uk Kim, Ki Cheol Park, Joo-Young Im, Kyoung-Jin Oh

Patent number: 10760051Abstract: The present invention relates to a method for producing astrocytes comprising obtaining neural progenitor cells from stem cells so as to continuously produce astrocytes with high purity and same traits, followed by two steps of differentiating the neural progenitor cells into the astrocytes, and astrocytes produced therefrom. Since the method of preparing the astrocytes provided in the present invention enables not only production of the astrocytes with high purity and faster production of the astrocytes with same characteristics, but also rapid differentiation of the astrocytes using the neural progenitor cells when necessary, it can be widely used for effectively treating a patient with a disease which requires transplantation of the astrocytes.Type: GrantFiled: August 13, 2015Date of Patent: September 1, 2020Assignee: Korea Research Institute of Bioscience and BiotechnologyInventors: Baek Soo Han, Sang Chul Lee, Kwang-Hee Bae, Cheonok Lee, Won Kon Kim, Kyoung Jin Oh
