The present study aimed to investigate whether curcumin in nanoparticle form may provide hepatoprotection in an ovarian cancer model in rats treated with cisplatin. Twenty-five female Wistar rats were divided into five 4-week treatment groups: (1) healthy rat group and four groups of 7,12-dimethylbenz(a)anthracene-induced ovarian cancer model rats receiving (2) vehicle only, (3) cisplatin 4 mg/kg BW/week, (4) cisplatin 4 mg/kg BW/week + curcumin 100 mg/kg BW/day, and (5) cisplatin 4 mg/kg BW/week + nanocurcumin (NC) 100 mg/kg BW/day. At the end of the treatment, a histopathological evaluation was carried out on the liver samples, in addition to oxidative stress, apoptosis, inflammatory, and fibrosis markers analyses. The group treated with cisplatin + NC had lower aspartate transaminase and alanine transaminase levels and lowered malondialdehyde and higher glutathione levels than those treated with cisplatin only. In addition, the nuclear factor-erythroid factor 2-related factor 2/Kelch-like ECH-associated protein 1 pathway genes were upregulated in the group treated with cisplatin + NC. We also demonstrated that NC effectively suppressed the gene expression of inflammatory marker tumor necrosis factor-α, as well as fibrosis marker transforming growth factor-β1. Furthermore, NC treatment reduced the fibrotic area in the hepatic tissues, as shown by Masson’s trichrome staining.
