  • Effects of Cantharidinate on apoptosis of human colorectal cancer UTC-116 cells were investigated by means of 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay, H and E staining, flow cytometry, and Raman Spectra analysis. The results showed Cantharidinate to exert inhibitory action on proliferation of human colorectal cancer UTC-116 cells, inducing apoptosis, arresting cells in G1 phase, with decline of S and G2 phases. In addition, the results of Raman spectrum showed significant changes in the UTC-116 cells chemical structure with stretching after the application of Cantharidinate. Taken together, these results suggest that the treatment of human colorectal cancer with Cantharidinate may be associated with multiple molecular mechanisms for apoptosis. Furthermore, similar to fluorouracil, Cantharidinate should be considered as novel assistant drug for controlling the growth of human colorectal cancer UTC-116 cells.

  • Effects of transforming growth factor-beta (TGF-${\beta}$) were investigated in human colorectal cancer, and the influence of cantharidinate in inhibiting TGF-${\beta}1$ expression was explored. Relationships among TGF-${\beta}1$ and sex, age, tumor size, tumor location, tumor stage were also analyzed. H&E and immunohistochemistry staining were employed to assess colorectal cancer and TGF-${\beta}1$ expression, respectively. Then, HCT-116 CRC cells were randomly divided into four groups, controls, no serum-treated, chemotherapy and cantharidinate-treated. Immunohistochemistry and real-time PCR were employed to assess the expression of TGF-${\beta}1$ in CRC cells. Our data showed that the expression of TGF-${\beta}1$ might be associated with tumor size and tumor location (P<0.05). The expression of TGF-${\beta}1$ in CRC groups was higher than in adjacent groups (P<0.05). In addition, the expression of TGF-${\beta}1$ in cantharidinate-treated group was much lower than in CRC group (P<0.05). Taken together, these results suggest that TGF-${\beta}1$ plays an important role in CRC development. Cantharidinate might inhibit the expression of TGF-${\beta}1$ and control the development of colorectal cancer.
