Expression of Zn transporter mRNA is positively regulated by prolactin (PRL) in normal breast cells (HC11). mRNA expression was measured by real-time PCR in cells treated with PRL for 12 h and compared with untreated cells. Expression of Zip6 and Zip10 were elevated two- and threefold relative to untreated cells. Data represent mean fold-change from untreated cells (n = 3 samples per group, mean ± standard deviation)
