Inhibition of transcription affects synthesis of steroidogenic acute regulatory protein and steroidogenesis in MA-10 mouse Leydig tumor cells.

abstract：:We constructed seven chimeric molecules in which sequential segments in the cDNA for thyroid peroxidase (TPO) were replaced with the homologous regions of myeloperoxidase (MPO) cDNA. The sizes of the translated cDNA segments A through G ranged from 23-175 amino acid residues in length. The TPO-MPO cDNA chimeras, inser...
