Expression profiling suggests a regulatory role of gallbladder in lipid homeostasis

Figure 1 Half of an array hybridization image from a normal gallbladder sample.

Figure 2 Scatterplot of two independent cDNA array analyses of the same sample. Each point stands for a gene or cDNA cluster, with the X coordinate representing the gene expression level in one test and the Y representing the value of the other test. An R² of 0.97 indicates high reproducibility of the cDNA array assay.

Figure 3 RT-PCR and sequencing confirmation of genes that were expressed in the gallbladder. RT-PCR electrophoresis result: A: CYP27A1(320 bp); B: NR1H4(352 bp); C: CMOAT(353 bp); D: AKR1C3(240 bp). Sequencing result of PCR product: E: CYP27A1; F: CMOAT.
