Based on the ACRG data, we found that the transcript level of SLC7A9 was higher in patients with microsatellite stable (MSS)/TP53 (−) tumours than in patients with MSS/TP53 (+) tumours, suggesting that the SLC7A9 expression level was related to TP53 status (Fig. 2a). The gene discussed is TP53; the disease is neoplasm.
