Figure 1From: Expression of LRP and MDR1 in locally advanced breast cancer predicts axillary node invasion at the time of rescue mastectomy after induction chemotherapyEthidium-bromide-stained agarose gel after RT-PCR amplification of MDR1 mRNA. The MDR1-expressing tumors are demonstrated by the presence of a 168 base-pair band, above the β-globin positive control (lanes 3, 4, 7, 8, 11, 13, 15, 16, 18, 20 and 22).Back to article page
