Prostaglandin-endoperoxide synthase-2 (PTGS2, Log2FC 5.416, p = 0.001) was the most highly expressed gene in this group with BAFF stimulation and is associated with chemoresistance and predicts poor survival in non-small cell lung cancer (NSCLC) (Figure 3D and Figure 4D) [45]. Here, PTGS2 is linked to non-small cell lung carcinoma.
