SLC1A3 and gastric adenocarcinoma: We also observed elevated SLC1A3 RNA levels in several tumor types from the TCGA database [especially kidney renal clear cell carcinoma (KIRC, P = 5.5 × 10−30), kidney renal papillary cell carcinoma (KIRP, P = 2.1 × 10−10), liver hepatocellular carcinoma (LIHC, P = 3.2 × 10−10), and stomach adenocarcinoma (STAD, P = 6.1 × 10−5)] (Fig EV1D).
