BACKGROUND: The study aims to examine the possible effect of melatonin against cisplatin-induced submandibular degeneration in experimental rats exploring its ameliorative mechanisms.
METHODS: Rats were classified into four experimental groups; control group; melatonin group; cisplatin group; and cisplatin+melatonin group. Submandibular tissues were collected. Biochemical, histopathological, and immunohistopathological examination and quantitative reverse transcription polymerase chain reaction (qRT-PCR) analysis were performed.
RESULTS: The results indicate that intraperitoneal administration of melatonin (30 mg/kg body weight) alongside cisplatin significantly elevated submandibular glands (SMG) and reduced glutathione (GSH) and superoxide dismutase (SOD) levels (p < 0.001), while it reduced malondialdehyde (MDA) levels, NF-κB gene expression, the protein level of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), interleukin-1 beta (IL-1β), immunoexpression of low-dose cyclooxygenase-2 (Cox-2), and CD68. Moreover, melatonin reduced immune and gene expression of alpha-smooth muscle actin (α-SMA), immunoexpression of caspase-3, and gene expression of Bax in comparison to the cisplatin group.
CONCLUSION: Melatonin attenuated cisplatin-induced submandibular destruction alleviating SMG oxidative stress, inflammation, and fibrosis in addition to halting cellular apoptosis, sheds light on its usage in clinical application.
