NTSR1 and central nervous system cancer: To support the involvement of neurotransmitter receptor genes in MBs’ progression, we examined the expression of NTR genes in two published scRNA‐seq datasets (Data source: GSE119926).[13, 16] Interestingly, most tumor cells prominently expressed synaptogenesis genes, similar to the reported phenomenon in gliomas.[35, 36] Synaptic gene enrichment was mainly found in clusters of MBs (Figure 4A,B; Figure S6A, Supporting Information), while various NTRs were upregulated in tumor cells.
