Publication number: 20080015158Abstract: It is intended to provide methods for suppressing the huntingtin gene expression by using a double-stranded RNA (dsRNA), huntingtin gene expression inhibitors to suppress the huntingtin gene expression, and preventives and/or remedies of Huntington's disease. Targeting against a specific sequence of mRNA at immediately upstream of CAG repeats in HD genes of Huntington's disease, the huntingtin gene expression is suppressed by using a dsRNA homologous to the sequence. In this invention, a short siRNA (short double-stranded RNA) having bp as short as around 21-23 bp can be effectively used as the dsRNA homologous to a specific RNA sequence in a region at immediately upstream of CAG repeats. The dsRNA of this present invention can be used as a huntingtin gene expression inhibitor, or a preventive and/or a remedy of Huntington's disease by administering or introducing into a living body or a living cell in mammals for the prevention and/or treatment of Huntington's disease.Type: ApplicationFiled: April 30, 2004Publication date: January 17, 2008Inventors: Kanazawa Ichiro, Liu Wanzhao, Yu-Lai Wang, Keiji Wada, Jun Goto, Miho Murata

Publication number: 20060131587Abstract: The present invention provides a manufacturing method of a high performance active matrix substrate at a high throughput with a less expensive apparatus, and an image display device using the active matrix substrate. On a stage moving in the short axis direction X and long axis direction Y on a rail, a glass substrate is carried, which has an amorphous silicon semiconductor film formed. Polycrystallized and large grain silicon film may be obtained by intensity modulating the pulsed laser beam in a line beam shape by means of a phase shift mask with a periodicity in the long axis direction Y of the laser beam, moving the laser beam randomly in the modulation direction of the amorphous silicon semiconductor film formed on the glass substrate to expose to crystallize the film. The image display device may incorporate an active matrix substrate having active elements such as thin film transistors formed by this silicon film.Type: ApplicationFiled: January 30, 2006Publication date: June 22, 2006Inventors: Takeshi Sato, Tazuo Takeda, Masakazu Saito, Jun Goto, Makoto Ohkura
