  • Patent number: 8426131
    Abstract: Investigation on the frequency of FLT3/ITD found in various blood cancers has revealed that the frequency is high in acute myeloblastic leukemia in particular. Studies on the effects of FLT3/ITD in the blood cell lines revealed that the tyrosine residues in FLT3/ITD is constitutively phosphorylated in these cell lines and that blood cells into which FLT3/ITD is introduced show IL-3 independent proliferation. Moreover, the blood cells into which FLT3/ITD is introduced are found to be capable of forming tumors and inhibit cell differentiation. The inventors have found that it is possible to screen for pharmaceutical compounds against tumors by using inhibition of these FLT3/ITD functions as an index.

    Abstract: The present invention provides methods for screening compounds which inhibit activation of a member of the IL-6 signaling pathways, comprising: (a) a positive screening step using a cell capable of being killed by IL-6 stimulation to select compounds which inhibit death of the cell when it is stimulated by IL-6; and then (b) a biochemical screening step to further select compounds which inhibit activation of a member of the IL-6 signaling pathways by a biochemical means from the compounds selected in step (a). The present invention also provides compounds which inhibit activation of a member of the IL-6 signaling pathways identified using said methods.

  • Patent number: 7503876
    Abstract: In a departure standby state in which a transmission is shifted to a drive stage and a mechanical clutch is disengaged, if a vehicle speed is greater than or equal to a predetermined value, the transmission is shifted to the neutral, and then the mechanical clutch is engaged. Then, it is determined whether the transmission is being rotated in reverse or not based on a rotational fluctuation on the driving side or the driven side in the process for engaging the mechanical clutch. When an accelerator pedal is pressed down at an angle greater than or equal to a predetermined angle, or when a gear shift instruction is input from the shift lever, if the transmission is being rotated in reverse the transmission is inhibited from being shifted to the drive stage, while if the transmission is not being rotated in reverse the transmission is shifted to the drive stage according to the pressed down state of the accelerator pedal, or a gear shift in instruction.
