Genes down-regulated in MCF-7 cells exposed to Gg using the human oxidative stress and antioxidant defence PCR array.

Gene symbol	Gene description	Expression relative to control
GPX	glutathione peroxidase-1	−24.59
SOD-3	superoxide dismutase	−10.78
MT3	metallothionein-3	−10.48
SFTPD	surfactant pulmonary associated protein-D	− 7.36
AOX1	aldehyde oxidase-1	−6.72

Cells were exposed to media containing 1 μM Gg or vehicle (control) for 24 h followed by RNA extraction and real-time quantitative PCR analysis. Results represent the mean of two independent experiments performed in triplicate.
