Protective effects of Aloe vera extract against doxorubicin-induced degeneration in ovarian follicles and stromal cells in mice.
The present study aimed to evaluate the protective effects of Aloe vera on doxorubicin (DOX)-induced degeneration in ovarian follicles and stromal cells in mice. Mice (n=48) were randomly divided into six groups. The positive control group mice received pretreatment of N-acetylcysteine orally (po), followed by a single intraperitoneal (ip) dose of DOX after 1 h (NAC+DOX). The negative control group mice were pre-treated with saline (po) and administered a single DOX dose (ip) after 1 h (SAL+DOX). The other groups of mice were pre-treated with different concentrations (0.1, 1.0, or 10.0 mg/kg; po) of Aloe vera and then received a single dose of DOX (ip) after 1 h (AV0.1+DOX, AV1.0+DOX, and AV10.0+DOX). The control group received saline po and ip (SAL+SAL). Aloe vera was administered once daily for 3 consecutive days. On the fourth day, the ovaries were processed for histological analysis, immunohistochemistry, and real-time PCR (mRNA for superoxide dismutase (SOD), catalase (CAT), nuclear factor erythroid 2-related factor 2 (NRF2), and tumor necrosis factor-α (TNF-α). Results showed that 0.1 and 1.0 mg/kg Aloe vera protected ovarian follicles and stromal density against DOX-induced degeneration. Furthermore, 0.1 and 1.0 mg/kg Aloe vera reduced TNF-α protein expression and increased NRF2, SOD, and CAT mRNA levels. In conclusion, 0.1 and 1.0 mg/kg Aloe vera had protective effects against DOX-induced degeneration in ovarian follicles and stromal cells in mice.
