Signaling pathways involved in paraquat-induced pulmonary toxicity: Molecular mechanisms and potential therapeutic drugs.

Paraquat poisoning is a severe health problem globally, particularly in developing countries. Due to its severe toxicity, the mortality rate of paraquat poisoning is greatly higher than other pesticide poisoning. Paraquat accumulates in the lung by specific polyamine uptake and causes a great amount of reactive oxygen species generation induced by redox cycling.

FAM129A promotes invasion and proliferation by activating FAK signaling pathway in non-small cell lung cancer.

Family with sequence similarity 129, member A (FAM129A), also called Niban or C1orf24, was initially identified from a rat model of hereditary renal carcinoma. FAM129A inhibited apoptosis and promoted migration and proliferation in human cancers. However, little is known about the downstream signaling during tumor progression.
