Fig. 3From: Transcriptional profiling of transport mechanisms and regulatory pathways in rat choroid plexusQuantitative expression of genes encoding SLCs. Illustration of the relative transcriptional abundance of the 11 SLC super-categories generated based on similarities in transported substrates (see Additional file 1, sheet 6). The area of each circle illustrates the relative accumulative transcription abundance in TPM (transcripts per million)Back to article page
