Benzylbutylphthalate是邻苯二甲酸酯(PAEs)的一员，通过上调Zeb1的表达，可引起血管瘤(HA)细胞的迁移和侵袭。Benzylbutylphthalate激活乳腺癌细胞中的芳香烃受体(AhR)，刺激SPHK1/S1P/S1PR3信号传导，促进转移性乳腺癌干细胞(BCSCs)的形成。
Benzyl butyl phthalate, a member of phthalic acid esters (PAEs), can trigger the migration and invasion of hemangioma (HA) cells via upregulation of Zeb1. Benzyl butyl phthalate activates aryl hydrocarbon receptor (AhR) in breast cancer cells to stimulate SPHK1/S1P/S1PR3 signaling and enhances formation of metastasis-initiating breast cancer stem cells (BCSCs)[1][2][3].
Benzyl butyl phthalate (BBP) is commonly added during the manufacturing of plastics to increase flexibility and elasticity[1].Benzyl butyl phthalate induces histone modifications in S1PR3 in side population (SP) cells, but not in non-SP cells[3].
