Gossypol Inhibits Metastasis of Lung Cell Carcinoma by Reversing Epithelial to Mesenchymal Transition and Suppressing Proteases Activity
Gossypol, a natural polyphenolic compound, possesses antivirus activity and induces cell death of different types of tumors. However, the efficacy of gossypol on lung carcinoma metastases and epithelial to mesenchymal transition remains unknown. The aim of the present work was to determine the cellular and molecular mechanism of the anti-cancer and anti-metastatic efficacies of gossypol on human lung carcinoma cells. Gossypol showed a marked suppression of the viability, motility, and invasion in H1299 and A549 cells. Zymography assay showed that gossypol was sufficient to suppress the activities of urokinase-type plasminogen activator and matrix metalloproteinase-2. Gossypol reversed TGF-β-induced epithelial to mesenchymal transition. Gossypol reduced vimentin, p-FAK, p-Src and p-paxillin. In vivo studies of gossypol were performed using subcutaneous inoculation and tail vein injection of A549 into immunodeficient BALB/c nude mice and severe combined immunodeficient mice.
期刊介绍：
The journal publishes in the areas of toxicity and toxicology of environmental pollutants in air, dust, sediment, soil and water, and natural toxins in the environment.Of particular interest are:
Toxic or biologically disruptive impacts of anthropogenic chemicals such as pharmaceuticals, industrial organics, agricultural chemicals, and by-products such as chlorinated compounds from water disinfection and waste incineration;
Natural toxins and their impacts;
Biotransformation and metabolism of toxigenic compounds, food chains for toxin accumulation or biodegradation;
Assays of toxicity, endocrine disruption, mutagenicity, carcinogenicity, ecosystem impact and health hazard;
Environmental and public health risk assessment, environmental guidelines, environmental policy for toxicants.
