SNORD17 and cancer: Literature data show that RN7SK RNA plays an important role in the process of neurodegeneration (Santoro et al., 2016), and the loss of this small RNA will reduce the transcription of cell cycle regulators, leading to cell cycle exit and differentiation, which may affect the occurrence of cancer (Bandiera et al., 2021); Liang et al. (2022) found that SNORD17 expression was significantly up-regulated in patient tissues.
