Finally, similarly to that reported for XIST and the other positive regulator FTX, JPX has an oncogenic role in gastric cancer and again the underlying molecular mechanism is based on a ceRNA mechanism: JPX increased the chemokine receptor CXCR6 by sponging its inhibitory miR-197 and thus promoting gastric cancer progression [190]. The gene discussed is CXCR6; the disease is gastric cancer.
