A. Kimura and colleagues "examined the mechanism by which estrogen regulates telomerase activity in Caov-3 human ovarian cancer cell lines, which express estrogen receptor (ER), to determine whether the regulation affects the expression and/or phosphorylation of the telomerase catalytic subunit (hTERT), 17beta-estradiol (E-2)-induced telomerase activity, and hTERT expression."

According to their paper in Oncogene, "Transient expression assays using luciferase reporter plasmids...
