Lung cancer

Lung cancer has been one of the most fundamental leading causes of death within the past 10 years[1].The severity of the disease is related to the metastatic potential and aberrant apoptosis of lung cancer cells.Metastasis is the process when cancer cells transport from their original tumor site and establish a secondary tumor elsewhere.These aggressive behaviors comprise their anoikis resistance and their migrate abilities[2].The process of a programmed cell death in an attached condition is called apoptosis whereas anoikis is a cellular mortality in a detached condition.One of the most essential processes of metastasis is cell migration where cancer cells are able to migrate through their surrounding extra cellular matrix and penetrate into the blood circulating system allowing them to freely settle at a novel site.Therefore,the discoveries of new therapeutic strategies targeting metastasis process and apoptosis cell death have garnered the most interest in cancer pharmaceutical sciences.Gigantol,a bibenzyl compound extracted from Dendrobium draconis,has been a promising natural derived compound for cancer therapy due to several cytotoxic effects in cancer cells[3].This study has discovered that Gigantol exhibits a metastasis inhibiting effect through enhancing detachment-induced apoptosis and reducing migration activities as well as inducing apoptosis in lung cancer cells. This fnding has proven that Gigantol could be a potential cancer therapeutic compound that should be further developed for cancer therapy.
