Accelerated progression of residual non-small cell lung cancer (NSCLC) after
incomplete radiofrequency ablation (RFA) has frequently been reported. In this
study, NSCLC cells A549, CCL-185, and H358 were treated using a water bath at
47°C for 5, 10, 15, 20, and 25 min gradually to establish the sublines A549-H,
CCL-185-H, and H358-H, respectively. A549-H, CCL-185-H, and H358-H cells showed a
significant increase in proliferation rate when compared with their corresponding
parental cellsin vitro The expression of hypoxia-inducible factor-1? (HIF-1?) was
obviously upregulated in both A549-H and CCL-185-H cells. Silencing of HIF-1?
abolished the insufficient RFA-induced proliferation in A549-H and CCL-185-H
cells. Furthermore, insufficient RFA treatment markedly elevated the
phosphorylation of ERK1/2 and Akt, but not of p38 MAPK or JNK, in A549-H and
CCL-185-H cells. The inhibitor of Akt, LY294002, but not the inhibitor of ERK1/2,
PD98059, suppressed the upregulation of HIF-1? and the proliferation of A549-H
and CCL-185-H cellsin vitro Thein vivoresults confirmed that insufficient RFA
could trigger the tumor growth, upregulate the HIF-1? expression, and activate
Akt in A549 xenograft tumors. Our data suggest that insufficient RFA can promote
thein vitroandin vivogrowth of NSCLC via upregulating HIF-1? through the PI3K/Akt
signals.
