As presented in Figure 1B, we knew that SNHG1 expression was elevated by MPP+ treatment but suppressed by RES pre-incubation in SH-SY5Y and SK-N-SH cells upon MPP+ treatment, suggesting SNHG1 might be involved in RES-mediated influences in the MPP+-induced cell model of PD. Here, SNHG1 is linked to Parkinson disease.
