SNORA31 and cancer: Furthermore, embedded within the Tumor Protein, Translationally-Controlled (TPT1) gene, which is known to be oncogenic in several cancers [35,36,37], the small nucleolar RNA 31 (SNORA31-001)–piR-24000 (piR_017184) pair was found to be significantly overexpressed in breast cancer tumor tissues as compared to normal breast tissues [38].
