In terms of treatment, in GC linked or not to H. pylori, the proteins nuclear receptor corepressor 1 (NCOR1), KIT proto-oncogene, receptor tyrosine kinase (KIT), KRR1 small subunit processome component homolog (KRR1), and ESF1 nucleolar pre-RRNA processing protein homolog (ESF1) play significant roles in the molecular processes of S-1, docetaxel, and cisplatin [29]. This evidence concerns the gene NCOR1 and gastric cancer.
