Recent studies have found that tumor cells can overexpress SLC6A6 to compete for taurine, thereby inducing T cell death and dysfunction and promoting tumor progression87; in addition, taurine secreted by TAM can inhibit ferroptosis in prostate cancer by activating the liver X receptor α/stearoyl-CoA desaturase 1 pathway.88 This evidence concerns the gene SLC6A6 and Familial prostate cancer.
