Abstract

The present study demonstrated two novel findings. To the best of our knowledge, it is the first study to demonstrate that regulated upon activation, normal T-cell expressed and secreted (RANTES), produced by breast tumor‑associated monocyte-derived dendritic cells (TADCs) following breast cancer cell exposure to phthalate esters, may contribute to the progression of cancer via enhancement of cancer cell proliferation, migration and invasion. Furthermore, the present study revealed that didymin, a dietary flavonoid glycoside present in citrus fruits, was able to reverse phthalate ester‑mediated breast cancer aggravation. MDA‑MB‑231 cells were treated with butyl benzyl phthalate (BBP), di‑n‑butyl phthalate (DBP) or di‑2‑ethylhexyl phthalate (DEHP). Subsequently, the conditioned medium (CM) was harvested and cultured with monocyte‑derived dendritic cells (mdDCs). Cultures of MDA‑MB‑231 cells with the conditioned medium of BBP‑, DBP‑ or DEHP‑MDA‑MB‑231 tumor‑associated mdDCs (BBP‑, DBP‑ or DEHP‑MDA‑TADC‑CM) demonstrated enhanced proliferation, migration and invasion. Exposure of the MDA‑MB‑231 cells to DBP induced the MDA‑TADCs to produce the inflammatory cytokine RANTES, which subsequently induced MDA‑MB‑231 cell proliferation, migration and invasion. Depleting RANTES reversed the effects of DBP‑MDA‑TADC‑mediated MDA‑MB‑231 cell proliferation, migration and invasion. In addition, didymin was observed to suppress phthalate‑mediated breast cancer cell proliferation, migration and invasion. The present study suggested that didymin was capable of preventing phthalate ester-associated cancer aggravation.
