Caco-2 or LS-180 cells were grown on Transwell® inserts, 4.71 cm2 for 7 (Caco-2) and 6 (LS-180) days. The cells were exposed to E1, E2, levothyroxine or rifampin for 24 h and 48 h. Total RNA was isolated by adding 1 mL Trizol® reagent (Gibco-BRL, Carlsbad, CA, USA) to the cells and processed according to the manufacturer’s instructions. The concentration and purity of isolated RNA samples were measured using Quant-iTTM RiboGreen® RNA assay kit (Invitrogen, Eugene, OR, USA). The RNA sample (0.06 µg) was reverse transcribed by an iScriptTM cDNA synthesis kit (Bio-Rad Laboratories, Hercules, CA, USA). Relative quantification of gene expression was performed by iTaqTM SYBR® Green supermix with ROX (Bio-Rad Laboratories) using an ABI Prism 7500 Real Time PCR system (Applied Biosystems, Foster City, CA, USA). Each experiment was performed in duplicate and repeated for each condition tested. The mRNA levels of all genes were normalized using 18s as an internal control. Results are expressed as ratios of MDR1 to 18s expression.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
