Publication number: 20190227066Abstract: This invention is directed to methods for the facile and accurate identification of cancer cells in a tissue sample, such as a surgical field. In particular, the compositions and methods employ conjugates comprising pro-fluorescent fluorescein based moieties bound to folic or pteroic acid targeting moiety optionally through a linker. The pro-fluorescent fluorescein based moieties are non-fluorescent but capable of being rendered fluorescent by intracellular processes. The conjugates are employed to detect cancer cells that overexpress folic acid receptors thereby providing for differential accumulation of these conjugates in these cells.Type: ApplicationFiled: August 22, 2017Publication date: July 25, 2019Inventors: John FANTE, Theodore HESSLER, III, Robert MORIARTY, Richard PARIZA, Gerald F.

Publication number: 20190227067Abstract: [Problem] The present invention addresses the problem of providing a novel biomarker which makes it possible to find the prognosis of glioma, the risk of distant recurrence of glioma, the invasion ability of glioma cells and the like and also makes it possible to detect the prognosis, the risk, the invasion ability or the like in an earlier stage of a therapy of glioma. [Solution] The present invention relates to a method for evaluating the prognosis of glioma, said method comprising the steps of: detecting ACTC1 protein and/or mRNA encoding the protein in a glioma-containing sample collected from a patient; and determining that the prognosis of the glioma is poor when the ACTC1 protein and/or the mRNA encoding the protein is detected in the aforementioned step. According to the present invention, the prognosis of glioma, the risk of distant recurrence of glioma, the invasion ability and the like can be evaluated using a novel biomarker, i.e., ACTC1 protein and/or mRNA encoding the protein.Type: ApplicationFiled: July 28, 2016Publication date: July 25, 2019Applicant: SAPPORO MEDICAL UNIVERSITYInventors: Osamu HONMOU, Masahiko WANIBUCHI, Shunya OHTAKI, Masanori SASAKI, Yuko SASAKI, Nobuhiro MIKUNI
