These reports together with our results support that ICMT, OGDH, TKT, ZMPSTE24, RPS6KA1, CACNA1B, and MAPK8IP3, as well as pathways for biosynthesis of antibiotics, terpenoid backbone biosynthesis, and MAPK signaling pathway may play important roles in osimertinib resistance in NSCLC. The gene discussed is CACNA1B; the disease is non-small cell lung carcinoma.
