Abstract

To investigate SOD-liked, GPx-liked and cellular anti-oxidation activities of fractionated mucus proteins from Perionyx excavatus (Pe) and Eudrilus eugeniae (Ee) in the MC3T3 osteoblast precursor cell line. The crude mucus proteins were extracted from Pe and Ee and fractionated using the anion exchange chromatography method with FPLC. The fractionated proteins were studied to determine their SOD-liked and GPx-liked activities. The most efficient fractions were studied for cellular anti-oxidation activities in the MC3T3 cell line including scavenging, protecting and repairing conditions. The results showed that the highest SOD-liked activities of EeANX1 were found at 4.17 µg/ml and GPx-liked activities of EeANX4 were found at 5.26 µg/mL. EeANX1 had no cytotoxic effect on MC3T3 at 500 µg/mL, and the IC50 of EeANX4 was over 300 µg/mL. When both EeANX1 and EeANX4 were investigated for cellular anti-oxidation activity in MC3T3 cells at 20 µg/mL, the cellular superoxide and total ROS production of were significantly (p<0.05) lower than those of 250 µM pyocyanin (ROS inducer) in ROS scavenging, protecting and repairing conditions. The 20 µg/mL of EeANX1 and EeANX4 demonstrated increased SOD and GPx activities in MC3T3. Investigation o...Continue Reading

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
