Enhancing radioprotection: exploring the impact of L-carnitine supplementation on the oxidative stress in the liver.
Background: The adverse effects of radiotherapy (RT) primarily occur through oxidative stress, and attempts are being made to mitigate these effects. L-Carnitine (L-Car) involved in physiological functions, possesses antioxidant and tissue-protective properties. The goal of this investigation is to appraise the radioprotective efficacy of L-Car supplementation.
Methods and results: The groups were established by dividing thirty-two rats as: control, RT (10 Gy), RT + L-Car (200 mg/kg/d), L-Car. Upon completion of the experiment, the livers were harvested for histopathological, immunostaining [tumor necrosis factor-alpha (TNF-α), Caspase-3], spectrophotometric [total oxidant status (TOS), total antioxidant status (TAS), oxidative stress index (OSI)], and mRNA expression [(Nuclear factor erythroid 2-related factor 2 (Nrf2), Kelch-like ECH-associated protein 1 (Keap-1), Heme Oxygenase (HO-1), Transforming growth factor beta 1 (TGF-β1)] analyses. In the damage group, decreased Keap-1, Nrf2, HO-1, and TAS values, along with increased histopathological findings, alanine transferase, aspartate transferase, TNF-α, Caspase-3, TOS, OSI, TGF-β1 levels were found. All findings were improved with L-Car treatment.
Conclusions: Considering these findings, it can be inferred that L-Car exhibits tissue-protective effects against organ damage predominantly induced by RT-related oxidative stress. Additionally, it has prevented the development of inflammation, apoptosis, and fibrosis. Therefore, L-Car may be considered as a supplement to reduce complications associated with RT.
期刊介绍:
Molecular Biology Reports publishes original research papers and review articles that demonstrate novel molecular and cellular findings in both eukaryotes (animals, plants, algae, funghi) and prokaryotes (bacteria and archaea).The journal publishes results of both fundamental and translational research as well as new techniques that advance experimental progress in the field and presents original research papers, short communications and (mini-) reviews.
