ABSTRACT / SAŽETAK:
Suppression of cell movement is an imperative in the effectiveness of future generations of chemotherapeutics. Frizzled 7 receptor (FZD7), as the first protein of Wnt/β-catenin signaling cascade, plays a significant role in regulation of cell differentiation, proliferation, and cell migration. This study aimed to investigate the potential effects of platinum (IV) complex: [PtCl4 (dbu-S, S-eddp)] – C1, and its corresponding ligand – L1 on cell movement, as well as the FZD7 expression and localization after treatments on two human colorectal carcinoma cell lines (HCT-116, SW-480). A Wound healing assay was used to examine cell migration, while FZD7 protein expression was examined by immunofluorescence. Chemical compounds, especially L1, reduced cell motility of both tested cell lines. They showed a particularly good effect on HCT-116 cells, increasing protein expression of the antimigratory marker FZD7 whose localization was observed on the cell membrane of HCT-116 cells. Suppression of cell movement was significantly lower in SW-480 cells after treatments, when compared to HCT-116, with an obvious decrease of FZD7 receptor expression and its localization in the cytoplasm of these cells. Our results indicate that among the examined treatments, the ligand showed more significant results in the suppression of HCT-116 cell movement, most likely through the stimulation of differentiation, which is indicated by the promotion of FZD7 expression.
