AB  - Introduction: Cuprizone is a copper chelating agent rensposible for toxic
demyelination. Although its mechanism of demyelination is not fully elucidated, its
toxicity is thought to result, at least partially, from induced autophagy.
The Aim: To examine the effect of cuprizone on autophagy markers in different
neural structures in rats with the assessment of behavior in the open field test.
Material and Methods: This study was performed on 16 female DA rats, 6 weeks
old.The control group (n=8) did not receive cuprizone, while the experimental group
(n=8) received food with 0.6% cuprizone content during 7 weeks. Afterwards,
locomotion and anxiety-like behavior were assessed in the open field test. Imunoblot
technique was performed on: cortex, corpus callosum, cerebellum and spinal cord, in
order to examine the markers of autophagy signaling pathway: pUlk, p62, Beclin1,
LC3II, pAMPK, pmTOR and pRaptor.
Results: Cuprizone-fed animals had a reduced locomotor activity and exhibited an
anxiety-like behavior. In the cortex, p62 and pAMPK were decreased, while pmTOR
tended to be lower. In the corpus callosum, pULK was increased and pmTOR was
decreased. LC3II tended to be increased, while pAMPK tended to be decreased. In the
cerebellum, pAMPK was reduced, while pmTOR was increased. In the spinal cord,
Beclin1 and pRaptor were decreased, while pmTOR, pAMPK, LC3II, p62 tended to
be decreased.
Conclusion: Long-term use of cuprizone leads to impaired locomotor activity and

anxiety-like behavior. Cuprizone-induced damage is most likely due to AMPK-
independent autophagy in the cortex and corpus callosum, while autophagy is

probably inhibited in the cerebellum and spinal cord.

AB  - The effects of tiazofurin (TR; 2-β-D-ribofuranosylthiazole-4-carboxamide), a purine nucleoside analogue on basal and amphetamine (AMPH)-induced locomotor and stereotypic activity of adult Wistar rat males were studied. The animals were injected with low (3.75, 7.5, and 15 mg/kg ip) and high (62.5, 125, and 250 mg/kg ip) TR doses. Neither low nor high TR doses influenced basal locomotor and stereotypic activity in comparison with the corresponding controls treated with saline only. However, pretreatment with TR at any dose applied, except for the lowest one, significantly decreased AMPH-induced (1.5 mg/kg ip) locomotor activity, while AMPH-induced stereotypic activity was inhibited with the two highest TR doses. In addition, TR was detected in the brain by HPLC already 15 min after the injection (125 mg/kg ip) to reach a maximum 2 h after the administration and was detectable in this tissue during the next 4 h. Our results indicate that TR modifies central regulation of the motor activity, possibly by influencing dopaminergic (DA-ergic) transmission.
