Objective: To study influence of acute hypoxia on the current of voltage-gated potassium channel (IK) in pulmonary artery smooth muscle cells (PASMC) of rats. Methods: A total of 20 male SD rats were randomly and equally divided into normoxic control group and acute hypoxia group. The rats in acute hypoxia group were kept in hypoxic chamber for 8 h before experiment. Whole cell patch-clamp technique was used to record IK in PASMC. Results: Acute hypoxia significantly decreased the IK density in PASMC of rats. During -60mV to -10mV of resting membrane potential（RMP）, acute hypoxia did not significantly decrease peak IK density in PASMC of rats, P>0.05; At 0 mV, acute hypoxia significantly decreased the peak IK density in PASMC [from（38.1 ± 5.2） pA / pF decreased to（9.82 ± 2.1） pA / pF ,P<0.05], then along with RMP increase in PASMC, the decreasing amplitude of peak IK density in PASMC gradually increased（P<0.05）; From + 30 mV to+ 60 mV, the decreasing amplitude of peak IK density in PASMC further significantly increased（P<0.01）; At + 60 mV the peak IK density decreased from（38.1 ± 5.2） pA / pF to（9.82 ± 2.1） pA / pF , and the decreasing amplitude reached (46.8±3.3)%. Conclusion: Acute hypoxia can decrease Kv current in PASMC of rats, leading to hypoxic pulmonary vasoconstriction.

Hedgehog (Hh) signaling pathway is present in many animals and plays an important role in regulating embryonic development and differentiation. Aberrant activation of Hh signaling contributes to the pathogenesis of many malignancies. Recent studies have shown that dysregulated Hh signaling pathway participates in the tumorigenesis, tumor invasion, and metastasis of hepatocellular carcinoma (HCC). Investigation of the relationship between Hh signaling pathway and HCC will help elucidate the molecular mechanism of pathogenesis of HCC and provide a new insight into the development of novel anticancer therapy and therapeutic target.
