RESUMO

The Withanolide D is a chemotherapeutic potential against the human tumor cell. However, there is no report on the effect of this compound on ovarian function, especially on preantral folliculogenesis. The aim of this study was to evaluate the toxicity of a new candidate to anticancer drug, Withanolide D (WD) on morphologic integrity, development (activation and granulosa cell proliferation) and gene expression of ABCB1 protein of caprine preantral follicles. Ovarian fragments were cultured in vitro for 2 or 6 days in α-MEM or α-MEM added with paclitaxel (PTX -0.1 µg/mL; negative control) and different concentrations of WD (WD1.5, WD3.0 or WD6.0). The higher dose of WD showed a toxic effect similar to PTX and higher (P < 0.05) than other treatments after 2 and 6 days. In addition, WD6.0 reduced the cell proliferating compared to PTX or mild dose. The expression of ABCB1 remained unchanged in the presence of the chemotherapeutic agents (PTX and WD) throughout the culture period. In conclusion, WD exerted a toxic effect observed by decreasing follicular survival and cell proliferation, on the preantral caprine follicles similar to PTX, whose negative effect on folliculogenesis is already widely known.
