Promensil is an over the counter plant based hormonal supplement used to treat menopausal symptoms, and is considered safer than human estrogen treatments. This project evaluates the model cell line, T47D-KBluc, which synthesizes luciferase in response to estrogen receptor binding, which can be used to quantify the binding affinity of each hormone. Using both luciferase assays and PCNA, the cell was examined for its growth and estrogen receptor activity when exposed to Promensil in order to determine that T47D-KBluc is responsive to estrogen like compounds. The findings can be used to support future studies of Promensil and its components in order to develop a better understanding of phytoestrogen drugs.
