S1PR5 and nervous system disorder: qRT-PCR study of 10 genes related to DNA damage or neurological disorders showed that the expression of Tubulin polymerization promoting protein family member 3 (Tppp3), sphingosine-1-phosphate receptor 5 (S1pr5), and RNA-binding protein with multiple splicing (Rbpms) was decreased, while the expression of Leptin receptor (Lepr) was increased in mouse blood after γ-irradiation (Figure 6A,B).
