“Nevertheless, nucleons reach 95% of chromatin decondensation in the presence of heparin plus GSH or heparin alone.”
“The fact that the correlation between heparin and GSH concentrations needed to induce sperm nuclei decondensation was 3- to 4-fold greater that in nucleons might be due to the complete lack of nucleon membranes.”
“Therefore, rupture of disulfide bridges is not the main mechanism to induce nuclei decondensation and perhaps the GSH role resides in potentate the heparin effect by increasing its negative charge.”
