Biflorin inhibits the proliferation of gastric cancer cells by decreasing MYC expression.

Gastric cancer is the third leading cause of cancer-related death worldwide. To evaluate the anticancer potential and molecular mechanism of biflorin, a prenyl-ortho-naphthoquinone obtained from Capraria biflora L. roots, we used ACP02, a gastric cancer cell line established from a primary diffuse gastric adenocarcinoma. In this study, biflorin was shown to be a potent cytotoxic agent against ACP02 by Alamar Blue and Trypan Blue assays. Morphological analysis indicated cell death with features of necrosis. Furthermore, a decrease in colony formation, migration and invasion of ACP02 cells was observed after treatment with biflorin (1.0, 2.5 and 5.0 μM). Regarding the underlying molecular mechanism of biflorin in ACP02 cells, we observed a decrease in MYC expression and telomere length using FISH. Our findings suggest a novel molecular target of biflorin in ACP02 cells, which may be a significant therapeutic approach for gastric cancer management.
