MGMT and neoplasm: Due to the small number of databases with data on the rare tumor, the mRNA levels of MGMT in human PanNET tissues and adjacent tissues were not significantly different according to the Gene Expression Omnibus (GEO) dataset (GSE73338) (Figure S1A, Supporting Information), whereas analysis of mouse GEO data (GSE248606) indicated that the expressions of MGMT were higher in PanNET tissues than in adjacent tissues (Figure S1B, Supporting Information).
