DNA damage is lethal and capable of inducing cellular aging or apoptosis. In this work, the highly tumorigenic and cisplatin-resistant human non-small cell lung cancer (NSCLC) cells were transfected with construct encoding the complete sequence of p16INK4a (p16). The stable clones with elevated p16 exhibited enhanced sensitivities to low concentration(More)
Ellipticine and its analogues were reported as topoisomerase II inhibitors and promising antitumor agents. In this work, we showed that the growth of human non-small-cell-lung-cancer (NSCLC) epithelial cells A549 can be inhibited by ellipticine. The inhibitory effect was reverted by PI3K inhibitors. The sub-G(1) phase cells after ellipticine treatment(More)
Cycas taitungensis Shen, Hill, Tsou & Chen is an endemic species remaining in two remnant populations in southeastern Taiwan. Ecological studies showed that the sex ratio between female and male of the main population is approximately 1.7:1. Leaf production was found to be correlated with tree height before reaching 1 m in length (r = 0.95). The annual(More)
The mechanism of action of Prunella vulgaris L. (PV) affecting cell migration and invasion of human liver cancer cells remains unknown. In this work we showed that the aqueous extract of PV affected migration and invasion of human liver carcinoma cells by inhibiting activities of metalloproteases, MMP-2 and MMP-9, without affecting cell viabilities. We(More)
We evaluated the possible anticancer performance of a natural compound, goniothalamin (GTN), against human lung cancer using as a non-small cell lung cancer (NSCLC) cell line, H1299, as the model system. Cellular proliferation was significantly inhibited by GTN. Using an improved alkaline comet-nuclear extract (comet-NE) assay, GTN was found to induce a(More)
A number of effective anti-cancer drugs contain either indole or quinoline group. Compounds fused indole and quinoline moieties altogether as indolylquinoline were rarely reported as anti-cancer agents. We reported here that a synthetic indolylquinoline derivative, 3-((7-ethyl-1H-indol-3-yl)-methyl)-2-methylquinoline (EMMQ), inhibited the growth of human(More)
In this work, we demonstrated that the growth of human non-small-cell-lung-cancer cells H460 and A549 cells can be inhibited by low concentrations of an epoxide derivative, teroxirone, in both in vitro and in vivo models. The cytotoxicity was mediated by apoptotic cell death through DNA damage. The onset of ultimate apoptosis is dependent on the status of(More)
As a practical and safe herbal medicine, the seeds of Brucea javanica (L.) Merr., were used to cure patients suffering from infectious diseases such as malaria. Recent advances revealed that the herb could also be a useful cancer therapy agent. The study demonstrated that aqueous B. javanica (BJ) extract attenuated the growth of human non-small-lung cancer(More)
Being effective and relatively safe, the traditional Chinese medicinal herb Brucea javanica (BJ) has been valuable in curing patients in East Asia and its nearby regions for years. Recent reports suggested that the medicinal herb possesses broad antitumor activity against various cancer cells. This study evaluated whether low concentrations of BJ aqueous(More)

The inhibitory effect of human epidermoid cancer cells A431 caused by conjugate toxin containing transforming growth factor (TGF-alpha) and ricin A was studied. TGF-alpha is a protein with 50 amino acids that specifically binds and stimulates phosphorylation of cell surface epidermal growth factor receptor (EGFR) and, subsequently, triggers cell(More)
