2019 JUN 06 (NewsRx) -- By a News Reporter-Staff News Editor at Cancer Gene Therapy Daily -- New research on Oncology - Prostate Cancer is the subject of a report. According to news reporting originating in London, Canada, by NewsRx journalists, research stated, “Early and accurate detection of cancer is essential to optimising patient outcomes. Of particular importance to prostate cancer is the ability to determine the aggressiveness of a primary tumour, which allows for effective management of patient care.”

Financial support for this research came from Prostate Cancer Canada.

The news reporters obtained a quote from the research from the University of Western Ontario, “In this work, we propose using gene vectors called tumour-activatable minicircles which deliver an exogenously encoded reporter gene into cancer cells, forcing them to produce a unique and sensitive biomarker. These minicircles express a blood reporter protein called secreted embryonic alkaline phosphatase mediated by the tumour-specific survivin promoter, which exhibits activity graded to prostate cancer aggressiveness. Together, these components underlie a detection system where levels of blood reporter are indicative of not only the presence, but also the metastatic potential of a tumour. Our goal was to assess the ability of tumour-activatable minicircles to detect and characterise primary prostate lesions. Our minicircles produced reporter levels related to survivin expression across a range of prostate cancer cell lines. When survivin-driven minicircles were administered intratumourally into mice, reporter levels in blood samples were significantly higher (p <0.05) in mice carrying prostate tumours of high versus low-aggressiveness.”

According to the news reporters, the research concluded: “Continued development of this gene-based system could provide clinicians with a powerful tool to evaluate prostate cancer aggressiveness using a sensitive and affordable blood assay.”
