20150072416 | METABOLITE FOR IMPROVING PRODUCTION, MAINTENANCE AND PROLIFERATION OF PLURIPOTENT STEM CELLS, COMPOSITION COMPRISING THE SAME, AND METHOD OF CULTURING PLURIPOTENT STEM CELL USING THE SAME - According to the present invention, when nicotinamide is added in a culture process for producing pluripotent stem cells from human differentiated cells, it can increase the efficiency of reprogramming and can significantly reduce the time required for induction of reprogramming. It was verified that nicotinamide inhibits the induction of senescence and oxidative stress in the reprogramming process and increases cell proliferation and mitochondrial activity to effectively improve culture conditions for induction of reprogramming. Particularly, the present invention will contribute to optimizing a process of producing induced pluripotent stem cells from a small amount of patient-specific somatic cells obtained from various sources, and thus it will significantly improve a process of developing clinically applicable personalized stem cell therapy agents and new drugs and will facilitate the practical application of these agents and drugs. In another aspect, according to the present invention, in defined culture conditions in which feeder cells and serum were not used, it was found that nicotinamide can provide a culture medium composition effective for maintaining the undifferentiated state of human embryonic stem cells and human induced pluripotent stem cells, which are typical pluripotent stem cells. The invention can be effectively used for the development of a high-efficiency system for culturing large amounts of human pluripotent stem cells, which is required for the industrialization of human pluripotent stem cells. | 03-12-2015 |

20120315284 | COMPOSITION FOR ENHANCING TRAIL SENSITIVITY COMPRISING INHIBITORS FOR EXPRESSION OR ACTIVITY OF TIP41 AS A TARGET GENE OF TRAIL SENSITIZER - The present invention relates to a pharmaceutical composition, including inhibitors for expression or activity of TIP41 protein, for prevention and treatment of cancer. When the liver cancer cell lines, showing resistance to TRAIL, are treated with TIP41 siRNA and TRAIL, apoptosis is induced in cancer cell. The same effect is found in cases of lung cancer and colon cancer with resistance against TRAIL. Moreover, this induction of apoptosis by TIP41 siRNA and TRAIL was confirmed in tumor xenograft, which was injected with Huh7 liver cancer cells and then was subjected to TIP41 siRNA transfection and TRAIL treatment. In addition, it was confirmed through animal experiments in which the tumor size has reduced and apoptosis was induced by treatment with TIP41 siRNA and TRAIL. Of note, MKK7/JNK pathway was confirmed to mediate the apoptosis induced by the application of TIP41 siRNA and TRAIL. The apoptosis were verified to be caused by the activation of MKK7/JNK signaling pathway. Taken together, the present invention provide the strong evidence that the pharmaceutical composition, including inhibitors for TIP41 expression or activity can be used for cancer prevention and treatment as well as an anti-cancer adjuvant. Taken together, the pharmaceutical composition comprising inhibitors for expression or activity of TIP41 protein may be used for prevention and treatment of cancer or as an anti-cancer adjuvant. | 12-13-2012 |
