Uptake transporter Slco1a1, 1b2, 1a6, Slc22a6, Slc22a7, Slc22a1 and Slc22a2 expression in kidneys of C57BKS and db/db mice. A) Messenger RNA expression of uptake transporters in kidneys of C57BKS and db/dB mice. Total RNA was isolated from kidneys of these mice, and mRNA was quantified by the branched DNA signal amplification assay. The data is plotted as average RLU per 10 μg total RNA ± SEM. B) Protein expression of Slco1a1 and 1b2 in crude membrane fractions from kidneys of C57BKS and db/db mice (n = 2). Proteins (75 μg/lane) were separated on 4–20% acrylamide/bis PAGE, transblotted, incubated with primary and secondary antibodies and visualized by fluorescence. C) Quantification of western blots by using the Quantity One® software (Biorad, Hercules, CA). The average band intensity for C57BKS males was considered 100% and other groups were compared with that density. Asterisks (*) represent a statistically significant expression difference between db/db mice and C57BKS control mice of the same gender (p≤0.05). Number signs (#) represent a statistically significant expression difference between male and female db/db mice or male and female C57BKS mice (p≤0.05). Slc22a7 mRNA expression was downregulated in db/db male and female mice. Slco1a1, Slc22a2 and 22a6 mRNA expression was downregulated in db/db males as compared to C57BKS males. Slco1a1, Slc22a2 and 22a6 mRNA expression was more in C57BKS males as compared to C57BKS females. Slco1a1 and 1b2 protein expressions were significantly decreased in db/db females as compared to C57BKS females.
