Gel electrophoresis of DNA was used for estimation of DNA changes caus
ed in C6 glioma cells by treatment with psychotropic drugs (imipramine
, amitryptiline and fluoxetine). Some discrete bands containing a popu
lation of short DNA fragments appeared after 1 and 5 days of cultivati
on. Apoptotic DNA breaks were verified at single cell level using the
TUNEL test in cells treated with fluoxetine.
