PTGES and lung cancer: Of those identified target genes, we selected HSPA6 (Figure 3A), histidine‐rich glycoprotein (HRG) (Figure 3B), ubiquitin D (Figure 3C), prostaglandin E synthase (PTGES) (Figure 3D), tyrosine kinase (TXK) (Figure 3E), and MMP2 (Figure 3F) and measured those gene expressions in eight lung cancer cells 48 h after treatment with acRoots at 10 mg/mL (Figure 3).
