STK11 and cancer: Figure 6 reveals that a meta-path of hsa-mir-17-STK11/LKB1 plays a key role in lung cancer by regulating cancer cell metabolism.34–36 STK11/LKB1 is a central regulator of T cell development, activation and metabolism.37 In addition, the T cell plays an important functional role in asthma as well.38 Collectively, hsa-mir-17-STK11/LKB1 may offer a potential pathobiological pathway for lung cancer-associated asthma.
