ADAMTS9 and gastric cancer: The results showed that high-dose cisplatin had little effects on both CR-GC cells and ACR-GC cells (Figure 5A–5D), and upregulation of LncRNA ADAMTS9-AS2 inhibited cell proliferation and viability in CR-SGC7901 and CR-BGC-823 cells to a very limited extent (Figure 5A, 5B).
