Steroidogenesis-related gene expression in the rat ovary exposed to melatonin supplementation

OBJECTIVE: To analyze steroidogenesis-related gene expression in the rat ovary exposed to melatonin supplementation. METHODS: Thirty-two virgin adult female rats were randomized to two groups as follows: the control group GI received vehicle and the experimental group GII received melatonin supplementation (10 µg/night per animal) for 60 consecutive days. After the treatment, animals were anesthetized and the collected ovaries were immediately placed in liquid nitrogen for complementary deoxyribonucleic acid microarray analyses. A GeneChip¯ Kit Rat Genome 230 2.0 Affymetrix Array was used f...
