GRIA2 and neoplasm: Studies have revealed that amongst the 6 identified target genes, Dpp6 [39] and Pcdh9 [40] were Tumor suppressor genes (TSGs) and Avpr2 [41], Cyp4a12b [42], Dpp6 [39], Gria2 [43], Pcdh9 [40] and Tspan11 [44] were key tumor-related transcripts that can regulate various pathways during carcinogenesis (Table 3).
