Study links gene with lung cancer:
This article was originally published in Clinica
Scottish scientists have identified a gene which could protect against lung cancer. The gene, which produces an enzyme called glutathione S-transferase that can detoxify cancer causing agents, has previously been linked with breast cancer (see Clinica No 804, p 27). In the new study, researchers treated the skin of mice with the carcinogenic chemicals found in cigarette smoke that are most closely linked to lung cancer. They found that that mice which lacked the gene developed three times as many precancerous tumours as those without the gene.
