Therapeutic potential of silica nanoparticles, cisplatin, and quercetin on ovarian cancer: In vivo model.

Abstract

The present study evaluated the effect of silica nanoparticles, quercetin, and cisplatin against ovarian cancer. Cisplatin is a potent antineoplastic agent but has greater toxicity against cancer. Quercetin is a powerful flavonoid with remarkable anti-cancer activity due to its anti-apoptotic nature. Forty female albino rats were randomly divided into eight groups, with five rats per group. Group 1 (G1) was normal control, G2 received Carboxymethylcellulose; G3 was the normal control and treated with quercetin, G4 was given silica nanoparticles, G5 was treated with cisplatin. G6 was the tumor control. Tumor induction was done by 7, 12-dimethylbenz (a) anthracene (DMBA), G7 was treated with quercetin-cisplatin-silica nanoparticles, and in G8 quercetin-cisplatin silica nanoparticles were used to treat the induced tumor. Chemically synthesized silica nanoparticles were characterized by scanning electron microscopy (SEM), energy dispersive X-ray (EDX), and Fourier Transform Infrared (FTIR). After the treatment, animals were sacrificed and tested for biochemical and hormonal assays. G6 displayed increased body weight and a significant rise in CA125 as compared to G1. G6 also exhibited an altered hormonal profile, with a particular increase in estrogen, FSH, and testosterone, along with reduced LH and progesterone levels. Lipid profile, liver enzymes, and renal parameters (urea and creatinine) increased in G6, but G8 significantly ameliorated all damaging effects of DMBA as observed in G6. The current study revealed that silica nanoparticles combined with cisplatin and quercetin demonstrated greater protection against drastic changes induced by carcinogens in ovarian cancer mice models.
