GRIN1 and hepatocellular carcinoma: Notably, gene hubs like Drd1, Gria1‐4, Grin1, Grin2b, Grm5, and GABAα receptor genes were also highly connected, mirroring gene expression patterns observed in liver fibrosis, cirrhosis, and hepatocellular carcinoma (HCC) (Stepanov et al. 2022; Wang et al. 2017; Zeng et al. 2023).
