(A) Immunoblot of telomerase protein in cultured human PBMCs treated with ethanol vehicle (control), with 1 M estradiol, or with a combination (PMA/Io) of PMA (phorbol myristate acetate; final concentration 50 ng/ml) and ionomycin (final concentration 1 g/ml). Molecular weight standards are shown at the left. (B) Quantitation of telomerase activity in human PBMCs under control conditions, treated with estradiol (1 M), or stimulated with PMA/Io as above. Telomerase activity is shown as amole of product/min/mg protein.
