Biological activity

JST-TfR09 (10 ng/well-200 ng; 48 h) reduces viability of MT2, Su9T1, and KK1, and this cell death is inhibited by ferrostatin-1 [1]. JST-TfR09 (100 ng/mL; 48 h) downregulates TFR1, FTH1, and FTL, upregulates IRP2 and NCOA4, and induces lysosome-dependent ferritin degradation and autophagy in ED, KK1, and MT2 ATLL cell lines [1]. JST-TfR09 (100 ng/mL; 48 h) increases intracellular ferrous iron, ROS, and lipid peroxidation (MDA) levels, key hallmarks of ferroptosis, in Su9T1, MT2, ST1, SO4, KK1, and ED ATLL cell lines and MOLT4, JURKAT T-ALL cell lines [1]. JST-TfR09 induces in vitro toxicity to human erythroblasts differentiated from CD34 hematopoietic stem cells at concentrations greater than 156 ng/mL [2]. . Increased cell viability to almost 80% in MT2, Su9T1, and KK1 ATLL cell lines when co-treated with ferrostatin-1. Western Blot Analysis [1] Cell Line: ATLL cell lines (ED, KK1, MT2) Concentration: 100 ng/mL; 25 uM Aloxistatin () + 50 uM Pepstatin A () (pretreatment); 10 uM MG132 () (pretreatment) Incubation Time: 48 h (JST-TfR09); 24 h (pretreatment prior to JST-TfR09) Result: Decreased TFR1, FTH1, and FTL protein levels in ED and KK1 cells. Increased IRP2 and NCOA4 protein levels in ED and KK1 cells. Prevented JST-TfR09-induced ferritin degradation in cells pretreated with lysosomal inhibitors, while proteasomal inhibitor pretreatment did not. Increased LC3-II expression relative to LC3-I in cells, indicating autophagy activation, which was blocked by lysosomal inhibitor co-treatment.
