Corynoxine suppresses lung adenocarcinoma proliferation and metastasis via inhibiting PI3K/AKT pathway and suppressing Cyclooxygenase-2 expression.

Background: Lung adenocarcinoma (LUAD) is the most common lung cancer subtype, and the prognosis of affected patients is generally poor. The traditional Chinese medicine Uncaria rhychophaylla has been reported to exhibit anti-lung cancer properties. Accordingly, the main bioactive ingredient in Uncaria rhychophaylla, Corynoxine, may hold great value as a treatment for lung cancer.

Leukemia inhibitory factor is involved in the pathogenesis of NSCLC through activation of the STAT3 signaling pathway.

Leukemia inhibitory factor (LIF) is a tumor promoter in several cancer types. However, the role of LIF in non-small cell lung cancer (NSCLC) remains to be explored. The present study explored the hypothesis that LIF is important for NSCLC development by measuring LIF expression and its downstream signal transducer and activator of transcription 3 (STAT3) phosphorylation in tumor samples derived from patients with NSCLC.
