GSTM1 and anemia (phenotype): LA-induced anemia could be attributed to binding lead to proteins in RBCs (García-Niño and Pedraza-Chaverri, 2014) as well as to shortening of RBCs’ life-span via depletion of the antioxidant system within the RBCs (Patra and Swarup, 2000; Lavicoli et al., 2003), inhibition of some Hb synthesizing enzymes (Dongre et al., 2011), and induction of RBC hemolysis via Hb oxidation (Flora et al., 2012).
