A team of researchers from IIT Madras, Cancer Institute, Sree Balaji Dental College and Hospital, Chennai, and Indian Institute of Science (IISc) Bengaluru have identified a specific microRNA (miRNAs) called ‘miR-155’ that is over-expressed in tongue cancer. MicroRNAs (miRNAs) are small Ribo Nucleic Acid. They are non-coding RNAs involved in the regulation of a variety of biological and pathological processes, including the formation and development of cancer. This finding is important in that molecular strategies can potentially be devised to manipulate miR-155 expression to develop therapeutics for tongue cancer.
