Individual members of the gene ontology category Unfolded Binding Protein are shown. The average intensity of all genes shown is above threshold. Fold changes and values beyond the cutoff for significance are in bold. For clarity, genes that do not reach significance in any category are not shown. Genes induced by MDMA are separated by a free line.

Real-time PCR validation of chaperone and heat shock gene upregulation by MDMA exposure (2 rats) versus unstressed untreated rats (3 rats). Fold change (2−ΔΔCt) is the normalized gene expression (2−ΔCt) in the test sample divided by the normalized gene expression (2−ΔCt) in the control sample. Fold regulation represents fold change results in a biologically meaningful way. Fold change values greater than one indicate a negative or downregulation and the fold regulation is the negative inverse of the fold change. Shown are positive changes in fold regulation by MDMA of at least 1.4 over controls.
