Patent number: 9169520Abstract: The present invention provides a novel cancer marker for evaluating the onset, the preclinical stage, the clinical stage, or the prognosis of a cancer in a subject, and an evaluation method using the same. A cancer marker containing at least one miRNA selected from hsa-miR-92 and hsa-miR-494 is used as a marker for cancers excluding breast cancer. A method for evaluating the possibility of cancers excluding breast cancer includes the step of detecting the expression level of a cancer marker in a biological sample collected from a subject. In this method, the cancer marker contains at least one miRNA selected from hsa-miR-92 and hsa-miR-494.Type: GrantFiled: September 27, 2013Date of Patent: October 27, 2015Assignees: NEC CORPORATION, TOKYO MEDICAL UNIVERSITYInventors: Masahiko Kuroda, Masami Tanaka, Kosuke Oikawa, Takayuki Mizutani, Masakatsu Takanashi, Seiko Iizuka, Yoshinori Kosugi, Kazuma Ohyashiki, Akihiko Tsuchida

Patent number: 8828964Abstract: Disclosed is an identification marker which can be utilized for detection of various human cancer cells and whose expression closely relates to malignant alteration of cells, and compositions for human cancer treatment which are based on suppression of cancer cell proliferation through inhibition of expression of the identification marker. The marker is human heterochromatin protein 1? (HP1?), and the compositions for cancer treatment comprises one or more agents which suppresses the expression of human HP1? gene, such as siRNAs to human HP1?.Type: GrantFiled: September 13, 2012Date of Patent: September 9, 2014Assignees: Accural Inc., MBC, Inc.Inventors: Masahiko Kuroda, Masakatsu Takanashi, Kosuke Oikawa

Publication number: 20130012412Abstract: An embodiment of the present invention provides a marker, a test method, and a test kit which can detect the onset of breast cancer that cannot be detected by palpation or mammography examination or breast cancer in an early stage (clinical stage 0), which are simple, and which have high reliability. A marker associated with breast cancer of an embodiment of the present invention is characterized by being a micro-RNA that is found in serum or plasma. More specifically, the marker contains at least a micro-RNA that is present in the serum or the plasma at a significantly reduced level after the onset of breast cancer, or during or after an early stage (during or after clinical stage 0) of breast cancer compared with that before the onset of breast cancer or before the early stage (before clinical stage 0) of breast cancer.Type: ApplicationFiled: September 14, 2012Publication date: January 10, 2013Applicants: KONICA MINOLTA HOLDINGS, INC., MIRACURE, INC.Inventors: Masahiko KURODA, Masami TANAKA, Kosuke OIKAWA, Takayuki MIZUTANI, Masakatsu TAKANASHI
