	1	In vitro effects of polyphenols on colorectal cancer cells显示文摘AIM:To investigate the effects of quercetin and genistein on colon cancer cell proliferation and their estrogen receptorβ(ERβ)expression.METHODS:Colon cancer cells were stably transfected with a mammalian expression vector to overexpress ERβ(HCT8-β8-expressing cells)or a control vector(HCT8-pSV2neo-expressing cells).The proliferation of these cells was examined after treatment with quercetin or genistein(5-100μmol/L),or 10 nmol/L17β-estradiol(17β-E2).Cell viability was examined by acridine orange staining following treatments for 48 or144 h.Effects of quercetin and genistein on ERβtranscriptional transactivation were examined by luciferase activity in HCT8-β8-expressing cells transiently transfected with a pEREtkLUC reporter vector.In addition,the regulation of ERβtranscription by phytoestrogens and 17β-E2 was examined by quantitative polymerase chain reaction.RESULTS:Proliferation of HCT8-β8-expressing cells was not reduced low doses(5μmol/L)of quercetin and genistein,while it was reduced at 25-50μmol/L with an effect similar to 10 nmol/L 17β-E2.Treatment with doses of phytoestrogens≥75μmol/L completely blocked cell growth and reduced overall cell counts,however no effects at any dose were observed in HCT8-pSV2neoexpressing cells.These results were supported by viability staining that revealed acridine orange-stained lysosomes with high doses or extended treatment periods.Genistein and quercetin(50μmol/L)significantly increased ER-responsive luciferase activity similar to 10nmol/L 17β-E2(P<0.05).Furthermore,genistein and quercetin(50μmol/L),as well as 10 nmol/L 17β-E2significantly increased ERβmRNA levels in HCT8-β8-expressing cells(P<0.05).In addition,treatment of HCT8-pSV2neo-expressing cells with 50μmol/L quercetin or 10 nmol/L 17β-E2 significantly increased ERβmRNA levels compared to untreated controls(P<0.05),though the absolute levels were much lower than in HCT8-β8-expressing cells.CONCLUSION:The antitumorigenic effects of the phytoestrogenic compounds quercetin and genistein on colon cancers cells occur through ERβactivity and expression.
