Cancer: Tumors secrete gaseous sulfur-containing compounds.

摘要

Volatile gaseous sulfur-containing compounds are produced by tumors and stimulate tumour proliferation, new findings show.Glycolytic metabolism is accelerated in cancer cells, resulting in the accumulation of glucose and methionine in these cells. In this study, the nonenzymatic Maillard reaction between glucose and methionine was found to result in the generation of sulfur-containing compounds, including hydrogen sulfide and methanethiol.
