Agarose gels to visualize bands from qPCR confirming that mRNAs for pregnane xenobiotic receptor (PXR) and its possible downstream effectors, steroidogenic acute regulatory protein (StAR), P450 side chain cleavage enzyme (P450scc), 5α-reductase (5α-red), and 3α-hydroxysteroid dehydrogenase (3α-HSD) are expressed in the rat midbrain. Note: gels depicted are those run separately for each of these targets.
