The insulin - like growth factor - 2 ( igf - 2 ) and igf conjugated protein - 6 ( igfbp - 6 ) mrna level in rat calvaria bone tissue and mc - 3t3 - el cells were detected by northern blotting analyses and reverse transcription polymerase chain reaction. the estrogen responsive element ( ere ) in igfbp - 6 gene promoter was identified and involved in tcdd - reduced regulation of the gene expression by electromobility shift assays ( emsa )
