Publication number: 20180292400Abstract: The invention relates to ex-situ biosensors that impedimetrically detect cardiac biomarkers of interest in a bodily fluid sample derived from a patient. The biosensors include a multi-array of vertically aligned platinum wires having immobilized thereon an aptamer that is selected to specifically and selectively bind to the cardiac markers of interest. The biosensors are contacted with a portion of the bodily fluid sample, and the aptamer binds to the cardiac markers of interest in the bodily fluid sample. As a result, an electrochemical impedance signal is generated and therefore, a change in electrochemical impedance is indicative of the presence of the cardiac markers of interest in the bodily fluid sample. The biosensors are point-of-care, on-demand devices that can be used in a medical environment, as well as in domestic settings.Type: ApplicationFiled: October 4, 2016Publication date: October 11, 2018Applicant: UNIVERSITY OF PITTSBURGH-OF THE COMMONWEALTH SYSTEM OF HIGHER EDUCATIONInventors: Prashant N.

Publication number: 20180245162Abstract: The present invention relates to methods and compositions for determining whether a subject having prostate cancer is at greater risk of developing progressive disease, and methods of treating the subjects. It is based, at least in part, on the discovery that approximately 90% of men carrying at least one of the following fusion genes: TRMT11-GRIK2, SLC45A2-AMACR, MTOR-TP53BP1, LRRC59-FLJ60017, TMEM135-CCDC67 and CCNH-C5orf30 experienced prostate cancer recurrence, metastases and/or prostate cancer-specific death after radical prostatectomy (each examples of “progressive prostate cancer”), while these outcomes occurred in only 36% of men not carrying any of these fusion genes. It is also based, at least in part, on the discovery that no patient studied survived five years without recurrence if their primary prostate cancer contained a TRMT11-GRIK2 or MTOR-TP53BP1 fusion gene. It is also based, at least in part, on the discovery that the protein encoded by the MAN2A1-FER fusion gene exhibits kinase activity.Type: ApplicationFiled: February 14, 2018Publication date: August 30, 2018Applicant: UNIVERSITY OF PITTSBURGH - OF THE COMMONWEALTH SYSTEM OF HIGHER EDUCATIONInventors: Jianhua Luo, Yangping Yu, Joel B.
