ADAMTS9 and gastric cancer: Based on this, we found that LncRNA ADAMTS9-AS2 was low-expressed, while miR-223-3p was high-expressed in CR-GC cells and ACR-GC cells, and continuous low-dose cisplatin stimulation significantly decreased LncRNA ADAMTS9-AS2, and increased miR-223-3p levels in GC cells, which suggested that the expression patterns of LncRNA ADAMTS9-AS2 and miR-223-3p were changed by cisplatin treatment.
