Figure 1From: Estrogenic microenvironment generated by organochlorine residues in adipose mammary tissue modulates biomarker expression in ERα-positive breast carcinomas Organochlorine levels modulate progesterone receptor expression in estrogen receptor-α positive breast carcinomas. The percentage of PR expression in ERα-positive breast carcinoma was positively correlated with organochlorine levels in the adjacent adipose tissue (Spearman's Rho test, P = 0.044).Back to article page
