Patent number: 9278108Abstract: A nucleic acid molecule that can bind to HMGB1 protein and applications thereof are provided. A nucleic acid molecule having a dissociation constant for HMGB1 protein of 5×10?7 or less can be used as the nucleic acid molecule that can bind to HMGB1 protein. The HMGB1 binding nucleic acid molecule can bind to HMGB1 protein that is known to be a cause of diseases such as cancer and inflammation, and it is therefore possible to obtain an effect to prevent and an effect to treat such diseases by allowing the HMGB1 binding nucleic acid molecule to bind to HMGB1 protein in a living body.Type: GrantFiled: July 16, 2010Date of Patent: March 8, 2016Assignees: NEC Solution Innovators, Ltd., Kanagawa Prefectural Hospital OrganizationInventors: Hiromi Takenaka, Jou Akitomi, Shintarou Katou, Shotaro Tsuji, Takashi Ohtsu, Iwao Waga

Publication number: 20130244239Abstract: The present invention is to provide a new detection method that is superior in detection sensitivity and allows a simple operation. A nucleic acid construct that includes a cloning region, an encoding nucleic acid of a peptide tag, an encoding nucleic acid of an aptamer that is bindable to the peptide tag is used. By inserting the encoding nucleic acid of arbitrary peptide into the cloning region of the nucleic acid construct, the nucleic acid construct is expressed in vivo. Thereby, a complex of a fusion transcript having the base sequence that includes the encoding nucleic acid of arbitrary peptide, the encoding nucleic acid of a peptide tag, and the encoding nucleic acid of the aptamer and a fusion translation that includes the arbitrary peptide and the peptide tag is formed.Type: ApplicationFiled: March 31, 2011Publication date: September 19, 2013Applicant: NEC SOFT, LTD.Inventors: Shotaro Tsuji, Makiko Tsuji, Takashi Ohtsu

Publication number: 20130102480Abstract: The present invention provides a prediction device, a prediction method, a program, and a recording medium, with which whether or not desired aptamer sequences are enriched can be predicted easily. The prediction device of the present invention 10 includes an input unit 11, a calculation unit 12, and a prediction unit 13. The input unit 11 is a unit through which sequence information on a target aptamer sequence group including selected aptamers in a target pool and a reference aptamer sequence group including reference aptamer sequences are inputted. The calculation unit 12 calculates the free energy of the target aptamer sequence group and the free energy of the reference aptamer sequence group. The prediction unit 13 compares the free energy of these sequence groups, and predicts that the target pool is an enriched pool when the free energy of the target aptamer sequence group is lower than the free energy of the reference aptamer sequence group.Type: ApplicationFiled: July 2, 2011Publication date: April 25, 2013Applicants: KANAGAWA PREFECTURAL HOSPITAL ORGANIZATION, NEC SOFT, LTD.Inventors: Jou Akitomi, Shintarou Katou, Shotaro Tsuji, Takashi Ohtsu, Iwao Waga
