Figure 2From: Estrogenic microenvironment generated by organochlorine residues in adipose mammary tissue modulates biomarker expression in ERα-positive breast carcinomas High organochlorine levels promote high proliferation in estrogen receptor-α positive breast carcinomas of postmenopausal. All ERα-positive breast carcinomas from postmenopausal women had high cellular proliferation when levels of organochlorine residues were 2600 ppb or higher (above the dashed line) (Fisher's exact test, P = 0.017 – statistical analysis of tumors with low and intermediate proliferation grouped).Back to article page
