An in vitro steroidogenesis assay using H295R human adenocarcinoma cells has been suggested as a possible alternative to gonad explant assays for use as a Tier I screening assay to detect endocrine active chemicals capable of modulating steroid hormone synthesis.

A number of environmental contaminants and plant flavonoid compounds have been shown to inhibit the activity of 3beta-hydroxysteroid dehydrogenase/Delta(5)-Delta(4) isomerase (3beta-HSD). Because 3beta-HSD plays a critical role in steroid hormone synthesis, inhibition of 3beta-HSD represents a potentially important mode of
