TABLE 1.

Changes in gene expression as determined independently by microarray and RT-PCR assays^a

Target	Comparison	Change in expression (fold) inb:
		Chip assay	RT-PCR
amyE	scoC cells, t2 vs t3	4.6 ↑	4.8–5.0 ↑
citC	scoC cells, t3 vs t4	7.2 ↓	5.3–7.1 ↓
sdhA	t2, scoC vs wild-type cells	1.0	0.99–1.0

^aThe expressions of amyE, citC, and sdhA were quantitated independently by microarray and RT-PCR assays as described in the text. 

^b↑ and ↓, gene expression increase and decrease between the compared conditions.
