Research is exploring the emerging roles of long non-coding RNAs in various contexts, including the nervous system, cancer, and muscle development. The functions of these RNAs are being investigated in relation to different diseases and conditions, such as epilepsy, glioblastoma, and cervical cancer. Studies are also examining the potential of non-coding RNAs, including circular RNAs and PIWI-interacting RNAs, in diagnostics and therapeutics.
