CDKN1A and small cell lung carcinoma: “Small cell lung cancer” was also extracted (P = 0.040, Table 4B) and included RXRB, E2F1, CDKN1A, and TRAF3. The combination of hsa-miR-6805-5p and hsa-miR-513b-5p for pathway analysis also provided “Antifolate resistance” (P = 0.016, Table 4B) as the resultant pathway with SHMT1, SHMT2, ABCC5, and IKBKG as the target genes.
