Figure 6. Expression of ABC transporters in PDT-resistant clones.

Figure 6

(A) qPCR analysis of most significantly upregulated ABC transporters. Expression of individual murine ABC transporters was measured using the TaqMan® Array Mouse ABC Transporters from Life Technologies. Gapdh was used for normalization. Each clone was analyzed in biological duplicate. Stars denote the significance of difference from 4T1 cells; one star, p < 0.05, two stars, p < 0.01. For actual data see Supplementary Table S4. (B) Western blot analysis of the most upregulated ABC transporters. The membrane carrying blotted proteins from cellular extracts of parental and PDT-resistant clones in biological duplicates was sequentially probed with ABCA1, ABCB1 antibodies and eventually with actin antibody to demonstrate equal protein loading.
