COX7A1 and cancer: Except Patient 1 (P1), the results from Patient 2 to Patient 6 (P2-P6) also showed that the expression of COX7A1 in tumor tissues was much lower than normal lung tissues in both RNA level and protein level (Fig. 1B–D), indicating the anti-cancer potential of COX7A1 during the process of NSCLC development.
