since 60 000 androgen molecules and 20 000 receptor molecules appear in the nucleus before transport stops , it seems that the quantity of 4.4 s cytoplasmic receptor estimated at 174 plus or minus 24 pmol per mg protein ( equivalent to about 8000 molecules per cell ) is insufficient to account for the total influx of androgens and androgen receptors into the nucleus .
