Pectolinarigenin inhibits non ‑small cell lung cancer progression by regulating the PTEN/PI3K/AKT signaling pathway.

Pectolinarigenin inhibits non‑small cell lung cancer progression by regulating the PTEN/PI3K/AKT signaling pathway. Oncol Rep. 2018 Oct 02;: Authors: Xu F, Gao X, Pan H Abstract Lung cancer is the principal cause of cancer‑-associated mortality. Pectolinarigenin (Pec) reportedly has effective antitumor activity against certain cancer types. Phosphatase and tensin homolog (PTEN) is a well‑known tumor suppressor and serves a vital role in cancer progression. However, the effect of Pec on non‑small cell lung cancer (NSCLC) cell proliferation and metastasis, and the underlying mechanism, has not yet been elucidated. In the present study, it was demonstrated that Pec inhibited the proliferation of A549 and Calu‑3 cells in dose‑ and time‑dependent manners. The apoptosis rate significantly increased with increasing doses of Pec. Apoptosis‑associated protein expression was additionally altered by Pec exposure. Pec was able to suppress the metastasis of NSCLC cells; it upregulated the mRNA and protein expression levels of E‑cadherin, and downregulated the mRNA and protein expression levels of vimentin. Additionally, Pec was able to activate PTEN and subsequently downregulate the PI3K/protein kinase B (AKT) signaling pathway. In summary, Pec was able to inhibit cell proliferation, promote apoptosis and suppress metastasis in NSCLC cells through the PTEN/PI3K/AKT signaling pathway, indicating that Pec is a potential agent for ...
