  • Publication number: 20110070245
    Abstract: IMP-1 was abundantly expressed in the majority of lung-cancers examined. Positive immunostaining of IMP-1 was correlated with tumor size (pT-classification; P=0.0003), non-adenocarcinoma histology (P<0.0001), low-histological grade (P=0.0001), and poor prognosis (P=0.0053). Suppression of IMP-1 expression with siRNA effectively suppressed growth of NSCLC cells. IMP-1 was able to bind to mRNAs encoding a variety of proteins involved in signal transduction, cell-cycle progression, cell adhesion and cytoskeleton, and various types of enzymatic activities. These results suggest that IMP-1 expression is likely to play important roles in lung cancer development and progression, and that IMP-1 is a prognostic marker and a promising therapeutic target for treatment of lung cancer.

  • Publication number: 20100291091
    Abstract: LY6K is identified herein as a potential biomarker useful for the diagnosis of cancer, such as lung and esophageal cancers, as well as for the prognosis of patients with these diseases. As discussed in detail herein, LY6K is specifically over-expressed in most lung and esophageal cancer tissues examined, and is elevated in the sera of a large proportion of patients with these tumors. Accordingly, LY6K may be used in combination with other tumor markers to significantly improve the sensitivity of cancer diagnosis. LY6K may be used in the treatment of ESCC cells, as demonstrated by the fact that small interfering RNAs (siRNAs) of LY6K suppressed growth of the cancer cells. Moreover, the LY6K molecule is also a likely candidate for development of novel therapeutic approaches, such as antibody therapy.

  • Publication number: 20100184047
    Abstract: The present invention is based on the observation that the co-activation of CDCA8 and AURKB, and their cognate interactions, play a significant role in lung-cancer progression.

  • Publication number: 20090208514
    Abstract: In order to identify the molecules involved in esophageal carcinogenesis and those to be useful for diagnostic markers as well as targets for new drugs and immunotherapy, a cDNA microarray representing 32,256 genes was constructed to analyze the expression profiles of 19 esophageal squamous-cell carcinomas (ESCCS) purified by laser-capture microdissection. A detailed genome-wide database for sets of genes that are significantly up- or down-regulated in esophageal cancer is disclosed herein. These genes find use in the development of therapeutic drugs or immunotherapy as well as tumor markers. Additionally, genes associated with lymph-node metastasis and post-surgery recurrence are disclosed herein. Among the candidate molecular target genes, a Homo sapiens epithelial cell transforming sequence 2 oncogene (ECT2) and a cell division cycle 45, S. cerevisiae, homolog-like (CDC45L) are further characterized.
