Gigantol Inhibits Epithelial to Mesenchymal Process in Human Lung Cancer Cells

الملخص EN

Lung cancer remains a leading public health problem as evidenced by its increasing death rate.

The main cause of death in lung cancer patients is cancer metastasis.

The metastatic behavior of lung cancer cells becomes enhanced when cancer cells undergo epithelial to mesenchymal transition (EMT).

Gigantol, a bibenzyl compound extracted from the Thai orchid, Dendrobium draconis, has been shown to have promising therapeutic potential against cancer cells, which leads to the hypothesis that gigantol may be able to inhibit the fundamental EMT process in cancer cells.

This study has demonstrated for the first time that gigantol possesses the ability to suppress EMT in non-small cell lung cancer H460 cells.

Western blot analysis has revealed that gigantol attenuates the activity of ATP-dependent tyrosine kinase (AKT), thereby inhibiting the expression of the major EMT transcription factor, Slug, by both decreasing its transcription and increasing its degradation.

The inhibitory effects of gigantol on EMT result in a decrease in the level of migration in H460 lung cancer cells.

The results of this study emphasize the potential of gigantol for further development against lung cancer metastasis.
