Significant clustering of bipolar disorder samples wasobserved (P=.005). B, Genes known to be involved in complexesI through V of the mitochondrial respiratory chain and present in at least20% of samples were used for clustering (n = 72). Significant clustering ofbipolar disorder samples (P=.004) and control samples (P=.02) was observed. Redundant probe sets were excluded from clusteringanalysis. Dark-shaded rectangles indicate bipolar disorder; light-shaded rectangles,schizophrenia; open rectangles, controls; L, lithium carbonate; V, valproicacid; and ?, treatment not known. Figure Legend:

The figure includes all genesrepresented on the HG- U95Av2 array (Affymetrix, Santa Clara, Calif) that codefor mitochondrial proteins involved in oxidative phosphorylation. Comparisonof the bipolar disorder group with the control group revealed that most geneswere down-regulated (indicated in blue), some were not significantly changedor had a presence call lower than 60% (indicated in yellow), and none weresignificantly increased. ATP indicates adenosine triphosphate; COX, cytochrome-c oxidase; Cyt, cytochrome; NADH, nicotinamide adenine dinucleotide;OSCP, oligomycin sensitivity–conferring protein; and RISP, Rieske iron-sulfurprotein. A dashed line around a box indicates that the gene was representedon the chip more than once (eg, Cyt C1); if a box has more than 1 color, thevarious representations of the gene on the array met different criteria asindicated by the colors (eg, subunit E). Fold difference is shown to the rightof the box (positive values calculated as bipolar disorder/control; negativevalues calculated as control/bipolar disorder). Figure Legend:

Four genes were selected for verification. A and E,The oligomycin sensitivity–conferring protein (OSCP), a subunit of mitochondrialadenosine triphosphate synthase. B and F, The mitochondrial cytochrome-c oxidase subunit, COX VIIb. C and G, The proteasome α-3 subunit.D and F, The proteasome β-4 subunit.
