GSTP1 rs1695 and rs1871042, and SOD2 rs4880 as molecular markers of lipid peroxidation in blood storage.

ABSTRACT:

Background

Red blood cells (RBC) are subject to oxidative stress by reactive oxygen species (ROS) during storage. Molecular characterisation of oxidative stress in stored RBC, which may also occur in other blood components during long periods of storage, is rare.

Materials and methods

Our study included 45 healthy RBC donors recruited in Brazil. Blood was collected into standard Grifols^® Triple Bags containing CPD SAG-M. Haematological values, biochemical data, and oxidative stress markers were assessed weekly during storage until 42 days after collection. GSTM1 and GSTT1 were determined by multiplex-polymerase chain reaction (PCR), while GSTP1 rs1695 and rs1871042, CAT rs1001179, and SOD2 rs4880 were evaluated by real-time PCR.
