carboplatin and thalidomide induced neuro-hepatotoxicity in rats

Carboplatin and thalidomide are good candidate’s treatments against many types of cancer. Latest studies

demonstrated that these chemotherapeutic drug cause oxidative damage. So, the present study was conducted to

estimate the neurotoxic and hepatotoxic effects induced by carboplatin/thalidomide regimen and to explore the

potential protective effect of Citrillus colocynthis extract (CCE) in rats. The obtained results showed that

carboplatin/thalidomide induced histological changes, caused significant elevation in serum liver enzymes, decline

in brain and plasma neurotransmitters, and increase in acetylcholine esterase. At the molecular level,

carboplatin/thalidomide caused marked elevation in inflammatory and apoptotic markers and suppressed the

expression of proliferator-activated receptor-gamma coactivator-1 and mitochondrial transcription factor a in brain

and liver tissues. Also, the regemin declined the GSH system and nuclear factor erythroid-2-related factor 2

(NRF2), and induced oxidative stress as indicated by elevated tissues level of thiobarbituric acid reactive substances

and 8-hydroxydeoxyguanosine. The co-supplemnation with CCE minimized thalidomide/carboplatin-induced

abnormalities in brain and liver tissues. As a result, the current findings revealed that CCE may have a protective

effect against carboplatin/thalidomide-induced toxicity.
