SCIENTIFIC INQUIRY Prostate cells usually require testosteroneand other androgens to survive. But some prostate cancercells thrive despite treatments that eliminate androgens.One hypothesis is that estrogen, often considered a femalehormone, may be activating genes normally controlled by an androgen in these cancer cells. Describe one or moreexperiments to test this hypothesis. (See Figure 11.9 to reviewthe action of these steroid hormones.)
