Taurine is an inhibitor of lipid peroxidation. Inhibits diethylnitrosamine and phenobarbital-induced hepatocarcinogenesis. Taurine has been used as a sulfur source in examining the gene expression profile of transporters in Bacillus subtilis via DNA array analysis. A report on the use of taurine as a sole sulfur source by several strains of E. coli has been published. The cytoprotective role of taurine has been investigated in cell culture. Taurine uptake in lactating porcine mammary tissue has been studied.
