摘要
The endocrine disrupting chemical o, p'-dichlorodiphenyltrichloroethane (DDT) can affect reproductive organs, tissues and cells in several species. Treatment of human endometrial endothelial cells (HEECs) with 50 mu M o, p'0- DDT decreased their proliferation compared with the control. Microarray analyses revealed that o, p'-DDT affected biological processes such as the cell cycle, cell division, defence response and lipid and steroid metabolism, in cellular components such as the plasma membrane and chromosomes, with molecular functions involved in signalling, receptor and cytokine activity, confirming the results of the proliferation assay. Expression of five of the most differentially expressed genes identified in the microarray analysis was verified by real- time quantitative reverse transcription polymerase chain reaction in five HEEC cultures obtained from women in the proliferative phase and in five cultures obtained from women in the secretory phase of the menstrual cycle after treatment with o, p'- DDT. The present study supports our previous findings of decreased proliferation and increased cell death in response to o, p'- DDT and may offer important clues to the mechanisms of action of o, p'-DDT.
