Abstract
AbstractTo illustrate the effect of nitric oxide (NO) on the microtubules of Sertoli cells (SC), SCs of piglets were treated with sodium nitroprusside (SNP). Changes in cell viability, anti-oxidant activity, enzyme activity and p38 mutagen-activated protein kinase (p38MAPK) activation were detected. The results were as follows. A low concentration of NO can keep SC microtubule and cell viability normal, and a high concentration of NO could increase p38MAPK activation, decrease anti-oxidant activity and transferrin secretion, and destroy the structure and distribution of the microtubules. The results suggest that SNP treatment results in an increase in NO in SCs and decreased cell anti-oxidant activity. The high concentration of NO destroys cell microtubules by activating p38MAPK.
