GRIN1 and breast cancer: For example, PP2A, TCL1, and Ndufb4b were upregulated in the HC vs. NC group, whereas both genes were downregulated in the NC vs. BC group (Figures S1 and S2); also the HC vs. NC group resulted in a significant downregulation of Grin1 and Rps6ka3, which reversed the upregulation of these genes in the NC vs. BC group (Figures S3 and S4).
