Australian Study Reveals New Mesothelioma Biomarker

A large multi-center Australian study has revealed what researchers say could be an important new biomarker for malignant mesothelioma. Mesothelioma is a virulent cancer of internal body membranes usually caused by exposure to asbestos. As with other cancers, mesothelioma cells produce certain compounds at higher levels than healthy cells do. Micro RNAs, or miRNAs, are short chains of ribonucleic acid, some of which are produced in abundance by cancer cells. Using miRNA microarrays, the Australian researchers profiled plasma samples from patients with malignant mesothelioma and from healthy controls. After reviewing 90 miRNAs previously associated with mesothelioma, they found two – miR-29c and miR-92a – in particularly high amounts. Further testing found a total of 15 novel miRNAs in the plasma of … Continue reading Australian Study Reveals New Mesothelioma Biomarker »
