Objective To study the relationship between calcineurin (CaN) activity and axon growth. Methods The cerebral cortical neurons of rats were cultured
and grouped as control group and cyclosporin A (CsA) group in which 10 nmol/L CsA was given when serum-free NB culture media was adopted. Inverted phase contrast microscope and digital photo collection system were used to harvest the photos of neurons cultured for 3
7
10 d. The length of axons were measured by SPOT software. The CaN activities were measured by enzyme substrate colormetric methods. Results After CsA stimulation
the length of axons increased significantly at 3
7 d (P0.05) and more notably at 10 d (P0.01)
meanwhile the CaN activities were more significantly inhibited at all time points (P0.01). Conclusion CaN activities have a negative relationship with axon growth.
