Interestingly, we found a lncRNA (LOC105378009) located in the upstream of SGK1 promoter region within 10kb space, therefore, in the present study, we sought to investigate the role of SGK1 within T cells of patients with gastric cancer (GC), and the association between SGK1 and LOC105378009 as well as the characteristics of GC and their potential prediction value for diagnosis or prognosis. This evidence concerns the gene SGK1 and gastric cancer.
