Abstract: The object aims to comprehensively analyze miRNA that undergoes epigenetic silencing in cancer to identify miRNA associated with cancer, elucidate the role of the identified miRNA in cancer, and develop a novel method for detecting cancer and a novel therapeutic agent for cancer both of which relate to the miRNA. Disclosed is a method for detecting cancer in a subject, which comprises detecting methylated CpG in a CpG island located in a promoter region of a microRNA 34b gene and/or a microRNA 34c gene in a biological sample collected from the subject. Also disclosed is a therapeutic agent for cancer, which comprises a nucleic acid encoding a BTG4 gene or BTG4, or comprises a nucleic acid encoding a miR-34b gene and/or an miR-34c gene or miR-34b and/or miR-34c.

Abstract: This invention relates to an agent, a composition and a product comprising at least one apoptosis-inducing substance, and at least one substance which inhibits expression and/or activity of an apoptosis-inhibiting substance; a method for inducing apoptosis or for treating a proliferative disease using one or more of them; a nucleic acid construct comprising a nucleic acid molecule encoding a protein to be expressed and a nucleic acid molecule which inhibits expression of an undesired protein; and a method for expressing a desired protein in a cell while inhibiting the expression of an undesired protein.

Abstract: The invention relates to a sample containing a gastric mucosa lavage fluid collected from a subject who has received a gastric mucus removal treatment and a method for detecting a disease-related marker using the same. By using the sample of the invention, the disease-related marker can be detected conveniently, less invasively, highly sensitively and highly accurately.

Abstract: Novel human genes usable in gene diagnosis and development of new therapeutic methods are disclosed. Specifically, human genes containing a nucleotide sequence encoding the entirety of or a portion of the amino acid sequence represented by SEQ ID NO:3, in particular, ones which are under the specific transcriptional regulation by a tumor suppressor gene p53.
