Washington [US], May 16 : Irregularities in the body's genetic code for protein production have been linked to malignant tumours. However, most genetic material contains components whose purpose is unknown.Could changes in non-coding material affect a person's health or possibly be linked to cancer?Based on a new study from Case Western Reserve University School of Medicine, non-coding DNA molecules play an important role in health and disease, including tumour growth.More specifically, they've discovered that these molecules may hold promise for warning of malignancies such as esophageal cancer, where a lack of biomarkers makes it hard to detect and treat tumours early."What we wanted to find out," said Kishore Guda, an associate professor at the School of Medicine and lead researcher of the study recently published in the peer-reviewed journal Gastroenterology, "was can we use these as potential biomarkers for developing cancers?"Ribonucleic acid (RNA) codes for proteins and carries genetic information in all living cells. In cancers, these RNA molecules are not only "turned on," but also appear to be activated in cells that are likely to progress to cancer.With that knowledge, it may be possible to detect cancers at an early stageor even before they become cancermaking it possible to improve patient outcomes and even survival.In their study, the researchers performed the first discovery and characterization of a specialized sub-class of what is known as "long intergenic" non-coding RNA molecules in esophageal malignancy.What they found: A panel of these molecules was also "turned on" in cancer tissues and in pre-malignant tissues (for example, those at high risk for becoming cancer). And these RNA molecules can be detected in patient biopsy tissues using routine imaging.Those RNA molecules also seem to inhibit the growth of esophageal cancer cells by regulating other genes potentially involved in cancer development, thus providing new opportunities for therapeutic targeting of these cancers, the authors concluded."Our study opens a new area of investigation by implicating these RNA molecules as additional players in esophageal cancer," Guda said. "Our goal is to understand how and when these molecules are turned on during esophageal cancer development, and how they control other genes involved in cancer processes."With this new knowledge, the team hopes to test whether the RNA molecules can be integrated into CWRU's EsoCheck molecular diagnostic panellicensed to Lucid Diagnosticsfor detecting cells at a high risk of becoming cancerous.They also want to test whether blocking the RNA molecules or blocking the genes controlled by these molecules, might lead to a new treatment strategy for cancer that is often lethal.Disclaimer: This post has been auto-published from an agency feed without any modifications to the text and has not been reviewed by an editor
