On the basis of the GDSC data, we analyzed drug sensitivity patterns in 8 gastric cancer cell lines with high SLC2A1 expression based on ATRA, known all−trans−retinoic acid, fluorouracil, a compound of oral fluoropyrimidine S-1, and oxaliplatin, known as XELOX [32]. The gene discussed is SLC2A1; the disease is gastric cancer.
