  • Publication number: 20140377768
    Abstract: The present invention provides a novel antitumor agent that acts through a novel mechanism. The novel antitumor agent contains as an active ingredient a substance capable of inhibiting a cell cycle-dependent Rho GTPase activating protein (RhoGAP). The RhoGAP is cell cycle-dependent and plays an important role in a process through which cancer cells acquire invasive capacity and/or metastatic capacity. The invasion and/or metastasis of cancer cells can be controlled by targeting the RhoGAP. Examples of the substance capable of inhibiting a cell cycle-dependent RhoGAP include an antisense oligonucleotide against a gene encoding the RhoGAP and an oligonucleotide that induces RNA interference of the gene. As the oligonucleotide, one containing an artificial nucleic acid such as BNA is preferred because of its excellent stability. The present invention also provides a screening method including selecting an antitumor agent capable of suppressing cancer cell invasion and/or metastasis through a novel mechanism.

  • Patent number: 4974198
    Abstract: A vector processing system prevents delays in reading microinstructions from a control memory during processing operations. The vector processing system permits a second microinstruction to be read from the control memory before processing is completed on a first microinstruction. Thus, delays caused by waiting for the processing to be completed on the first microinstruction before loading the next microinstruction are prevented. The disclosed vector processing system incorporates a start command hold flag that holds the start command from a second microinstruction until the processing initiated by the first microinstruction is completed.

  • Patent number: 4882701
    Abstract: A branch instruction processing unit executes a branch-on-count (BCT) instruction for loop control of a program by means of pipeline control. The unit includes a memory for storing the number of loops for each BCT instruction, a first storage register for storing the output of the memory, a detection circuit for detecting if the output of the memory is a "1" while the output is stored in the first storage register, a second storage register for storing the output of the first storage register, and a branch judgement circuit which judges if each instruction is taken in response to the detection of a "1" by the detection circuit while the output of the first storage register is being stored in the second storage register.

  • Patent number: 4476525
    Abstract: A pipeline-controlled data processing system includes decoding apparatus for decoding successive instructions and a detection device responsive to the decoding apparatus output for determining when a particular two-instruction sequence is present. When a first instruction calls for an operation to be executed and the execution result to be loaded into an arithmetic register, and when a second instruction immediately following the first instruction calls for the storing of the output of the arithmetic register into both a main memory unit and a cache memory, the execution result is simultaneously stored in all of the arithmetic register, main memory and cache memory.
