Abstract: The present invention relates to a pharmaceutical composition for preventing and treating cancer or inflammatory disease, containing an NDRG3 expression or activity inhibitor as an active ingredient. Furthermore, the present invention relates to an NDRG3 protein-specific antibody and a use thereof. Specifically, the antibody to the NDRG3 protein is prepared, and the antibody is used to verify that NDRG3 mediated by lactate generated from a hypoxia reaction promotes cell proliferation, angiogenesis, and cytokine expression through the lactate-NDRG3-c-Raf-ERK signaling pathway, and thus the antibody binding to the epitope of the NDRG3 or a fragment of the antibody can be favorably used in the research of cancer or inflammation occurrence mechanism, the development of novel genes involved in the mechanism, and the development of therapeutic agents and new pharmaceuticals.

Abstract: The present invention relates to the elucidation of a gene that can act as a novel marker for liver cancer diagnosis and to diagnostic and prognostic measurements of liver cancer using the same. More specifically, it relates to a diagnosis kit that enables diagnostic and prognostic measurement of a liver cancer using a preparation that measures expression levels of at least one gene selected from a group of liver cancer diagnosis markers consisting of S100P, NK4, CCL20, CSPG2, PLAU, MMP12, ESM-1, ABHD7, HCAPG, CXCL-3, Col5A2, MAGEA, GSN, CDC2, CST1, MELK, ATAD2, FAP and MSN and/or a method for diagnostic and prognostic measurement of liver cancer using the same. These have been discovered using normal liver tissues and liver cancer tissues collected from the same liver cancer patient of the present invention and represent the markers whose accuracy and reliability have been greatly improved as markers of liver cancer.

Abstract: The present invention relates to a method for detecting a colon cancer in a human, comprising the steps of: (a) providing a biological sample from the human; and (b) detecting the level of a ATAD2 nucleic acid or a ATAD2 protein in the biological sample, relative to the level of the ATAD2 nucleic acid or the ATAD2 protein in a control sample from a normal human, wherein an increased level of the ATAD2 nucleic acid or the ATAD2 protein in the biological sample compared to the control sample indicates that the human has the colon cancer. The biomarker of this invention was identified using normal colon tissue, colon cancer tissue and metastatic cancer tissue derived from a colon cancer patient. Therefore, the accuracy and reliability of the present biomarker for colon cancer and/or metastasis are much more significantly improved. In addition, the biomarker of this invention permits to identify and predict colon cancer or metastasis in an accurate manner.
