Consistent with the previous findings observed in the MPTP‐PD mouse model (Iwata et al, 2004; Stichel et al, 2005), SGK1 expression increased in the SNCA‐injected SN and the increased SGK1 expression was ubiquitously detected in neuron, astrocyte, and microglia populations (Appendix Fig S8). The gene discussed is SGK1; the disease is Parkinson disease.
