The results indicated that the expression level of AFAP1-AS1 was significantly upregulated in cancerous tissue of 80.61% (79/98) lung cancer patients comparing with paired non-tumor tissues (p < 0.05; Figure 1A and 1B), with a median difference of approximately 2.44-fold (p < 0.05; Figure 1C). The gene discussed is AFAP1; the disease is lung cancer.
