Thus, 10 studies had addressed 9 different types of cancer: 2 focused on gastric cancer (GC),[9,10] 2 on colorectal cancer,[11–12] 1 on esophageal squamous (ESC),[13] 1 on bladder cancer (BC) and prostate cancer,[15,16] 1 on hepatocellular carcinoma (HCC),[8] 1 on Glioma (GLO),[9] and 1 on Osteosarcoma (OSC).[17] The ZEB1-AS1 expression level was measured in all cancerous specimens. The gene discussed is ZEB1; the disease is gastric cancer.
