  • Publication number: 20170182012
    Abstract: It has been revealed that, from a pre-onset stage of Alzheimer's disease, enhancement of phosphorylations of MARCKS and the like causes abnormal spine formation or the like, consequently developing the disease. Moreover, it has also been revealed that the phosphorylations of MARCKS and the like are caused by PKC and the like, and further that b-raf is involved in the phosphorylation of a tau protein important for the progression of Alzheimer's disease. Thus, these proteins have been found to be target molecules useful in the diagnosis and treatment of Alzheimer's disease. In addition, it has also been revealed that, in a pre-onset stage of frontotemporal lobar degeneration also, b-RAF phosphorylation enhancement causes a decrease in the number of spines and the like, consequently developing the disease. Thus, b-RAF has been found to be a target molecule useful in the diagnosis and treatment of frontotemporal lobar degeneration.

  • Publication number: 20160053257
    Abstract: The present inventors have found microRNAs which are strongly associated with stabilization of NRF2 in tumors, and an object of the present invention is to provide means for utilizing such miRNAs for the diagnosis and treatment of cancer. The inventors conducted screening of 470 microRNAs in a microRNA library by use of HeLa cells. As a result, 8 miRNAs each exhibiting a large decrease in miRNA activity as compared with a control miRNA, and 8 miRNAs each exhibiting a large increase in miRNA activity as compared with a control miRNA, were identified. The inventors have found that the NRF2 activation in the living body, in particular tumor cells, can be detected by use of the thus-identified miRNAs, whereby malignancy of a tumor, or the like can be differentiated. The inventors have also found that a nucleic acid including a miRNA sequence associated with reduction in the aforementioned ARE activity can be used as a cancer therapeutic agent.
