OBJECTIVE: Aim: To study apoptotic processes and their role in the formation of premature dopaminergic neurodegeneration, to identify key biomarkers for early diagnosis and implementation of complex measures towards braking the progression of PD in the early stages, to develop possible treatment regimens with a specific neuroprotective effect on the dopaminergic system.
PATIENTS AND METHODS: Materials and Methods: The experiment involved 90 Wistar rats (6 months old, 220-290 g). Parkinsonism was induced by the neurotoxin MPTP (N-methyl4-phenyl-1,2,3,6-tetrahydropyridine). Intact animals received saline (1 ml/100 g, i.p.); the control group received MPTP followed by saline. Rats were divided into nine groups: I - intact; II - PD control; III - PD + Amantadine (AM); IV - PD + AM + Cerebrocurin; V - PD + AM + Pramistar; VI - PD + AM + Gliatilin; VII - PD + AM + Noophen; VIII - PD + AM + Pronoran; IX - PD + AM + Melatonin.
RESULTS: Results: The data obtained indicate that neuroprotective therapy of PD with drugs such as melatonin, cerebrocurin, pronoran, and gliatilin in combination with amantadine leads to an increase in the expression of the HIF-1α, HIF-3α, and HSP70 genes, and can also serve as a molecular marker for the activation of endogenous neuroprotection mechanisms under experimental PD conditions.
CONCLUSION: Conclusions: We have experimentally demonstrated a new target of neuroprotection in PD conditions - apoptosis of dopamine-producing neurons and substantiated modulators of this process - drugs for combined therapy with amantadine (melatonin, cerebrocurin, pronoran, and gliatilin) as promising drugs for PD treatment.
