Carboplatin-based Nanomedicine to Enhance the Anticancer Effect in SK-NEP-1 WilmsꞌTumor Cells

Wilms tumor (WT) is the most common pediatric malignant primary renal tumor. Carboplatin (CRB), a platinum compound is widely used in the treatment of multiple cancers including ovarian, lung, head and neck, and wilm's tumor. However, lower uptake of CRB in cancer cells and toxicity concerns in healthy cells often limited its clinical outcome. The aim of this study was to investigate the antitumor effect of CRB on SK-NEP-1 wilm's cancer cells. Earlier, CRB was formulated in nanoparticulate formulations and characterized its biophysical parameters. SK-NEP-1 cell growth in vitro was assessed by MTT. Then, apoptosis potential was investigated by TUNEL, Hoechst, and colony formation assay. CRB treatment resulted in inhibition of cell proliferation of SK-NEP-1cells in a dose-dependent manner. TUNEL, Hoechst, and colony formation assay demonstrated that CRB was more effective in killing wilm's cancer cell when encapsulated in nanoparticle formulations. Overall, the present study demonstrates that CRB treatment resulted in marked inhibition of cell proliferation and cell apoptosis. These results may pave way for the effective treatment of wilm's tumor in clinical models.
