Estrogenic Evaluation and Organochlorine Identification in Blubber of North Sea Harbour Porpoise (Phocoena phocoena) Stranded on the North Sea Coast

Figure 4

Estrogen receptor- (ER-) mediated antagonistic activity elicited by North Sea harbour porpoise blubber samples () in MCF-7-ERE cells when exposed simultaneously to E2 (5.0 × 10⁻³ ng/mL). The horizontal dashed line represents the response of the cells exposed to 5.0 × 10⁻³ ng/mL of E2. Results are expressed as percent of the maximal response induced by E2. Asterisks indicate that the response is significantly different from the response of 5.0 × 10⁻³ ng/mL of E2 ().
