BIRC5 and gastric cancer: The gene expression levels of microtubules (i.e., baculoviral IAP repeat-containing 5 (BIRC5), F-Box protein 5 (FBXO5), RuvB-like AAA+ ATPase 2 (RUVBL2), and kinesin family member 15 (KIF15)) were downregulated in JK-206-treated GC cells compared to the control group (Figure 4b and Figure 5b).
