Abstract
Cyclophosphamide (CP) is an antineoplastic drug widely used in chemotherapy. Curcumin (CUR) and piperine (PP) show a protective effect on neurodegenerative and neurological diseases. This research was designed to measure several biochemical parameters in the brain tissue of CP-applied rats to investigate the impact of combined CUR–PP administration. The study evaluated six groups of eight rats: Group 1 was the control; Groups 2 and 3 were administered 200 or 300 mg/kg CUR-PP via oral gavage; Group 4 received only 200 mg/kg CP on day 1; Groups 5 and 6 received CP + CUR-PP for 7 days. Data from all parameters indicated that CP caused brain damage. Phosphorylated TAU (pTAU), amyloid-beta peptide 1–42 (Aβ1–42), glutamate (GLU), and gamma amino butyric acid (GABA) parameters were the same in Groups 4, 5, and 6. On the other hand, 8-hydroxy-2-deoxyguanosine (8-OHdG), nitric oxide (NO), interleukin-6 (IL-6), nuclear factor kappa beta (NF-kβ), malondialdehyde (MDA), and tumor necrosis factor-alpha (TNF-α) levels in the CP + CUR-PP groups were lower than those in the CP group (p < 0.05). However, superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), and reduced glutathione (GSH) parameters were higher in the CP + CUR-PP groups compared to the CP group (p < 0.05). It is thought that the similarity of Groups 5 and 6 with Group 4 in Aβ1–42, pTAU, GLU, and GABA parameters hinder the determination of treatment protection however, they might have a therapeutic effect if the applied dose or study duration were changed. This study attempted to evaluate the effects of a CUR–PP combination on CP-induced brain damage in rats by measuring biochemical parameters and performing histopathological examinations. Based on the findings, this CUR–PP combination could be considered an alternative medicine option in cases with conditions similar to those evaluated in this study.
期刊介绍:
The Journal of Biochemical and Molecular Toxicology is an international journal that contains original research papers, rapid communications, mini-reviews, and book reviews, all focusing on the molecular mechanisms of action and detoxication of exogenous and endogenous chemicals and toxic agents. The scope includes effects on the organism at all stages of development, on organ systems, tissues, and cells as well as on enzymes, receptors, hormones, and genes. The biochemical and molecular aspects of uptake, transport, storage, excretion, lactivation and detoxication of drugs, agricultural, industrial and environmental chemicals, natural products and food additives are all subjects suitable for publication. Of particular interest are aspects of molecular biology related to biochemical toxicology. These include studies of the expression of genes related to detoxication and activation enzymes, toxicants with modes of action involving effects on nucleic acids, gene expression and protein synthesis, and the toxicity of products derived from biotechnology.
