This research project yielded the following results.1) Predictive factors for aggressive recurrence of hepatocellular carcinoma (HCC) and identification of a novel molecular target: A prognosis of HCC patients was found to depend on the mode of recurrence, and prognostic indicators were tumor differentiation, tumor size, and aurora kinase B (ARKB) which plays a key role in genome instability. ARKB is considered to be a promising molecular target for HCC treatment.2) Clinical implication of Gap junctional intercellular communication, Conexin (Cg) 43:3) Cx 43 was found to facilitate the growth of HCC, and to be a possible molecular target, and also Vitamin K 2 was found to suppress HCC growth through upregulation of Cx32 and downregulation of Cx43.4) Identification of genes responsible for carcinogenesis and development of HCC : We identified CREB3L4, INTS3, SNAPAP located at 1q 21.5) Identification of genes responsible for pancreatic cancer metastasis : We identified Gr7 which is phospholylated with FAK, thereby inducing cell invasion. We synthesized a peptide, G7-18NATE-P which inhibits phospholylation of Grb7, thereby clarifying the inhibitory effect on the peritoneal dissemination model of pancreas cancer.6) Effect of Iκ B kinase (IKKB) inhibition on pancreas cancer: SiRNA and synthesized compound, IMD-0354 for IKKB inhibitor were found to suppress the growth of pancreas cancer in the xenograft model.

该研究项目产生了激进的肝细胞癌反映（HCC）的因素的因素：hcc患者的程序员依赖于递归分化的方式，肿瘤大小和极光激酶B（ARKB），在该模式中起着关键作用基因组不稳定性。 .4）鉴定基因对癌变的反应和HCC的发展：我们确定了CREB3L4，INTS3，SNAPAP位于1q 21.5）确定的GR7 HICH被FAK磷酸化，从而诱导了细胞的侵袭。胰腺癌的腹膜模型。6）对胰腺癌的乳腺癌：siRNA和合成化合物，IKKB抑制剂的IMD-0354，可抑制施加仪模型中p骨癌的生长。
