PMCH and cancer: In the patient group, decreased expression was observed in genes such as DCC (clusters 13 [GABAergic neurons], 17 [glutamatergic neurons], 5 [glutamatergic neurons], 18 [neuroblast], and 1 [glutamatergic neurons]), PMCH (cluster 9 [neural progenitor cells]), HTR2C (cluster 7 [cancer cell]), and TTR (cluster 7 [cancer cell]), and DPP10 (cluster 4 [glutamatergic neurons]).
