It was noted that levels of the protein, βarrestin2, were lower in certain prostate cancer cells than in normal prostate cells. It was also noted that the expression of testosterone-fed androgen receptors is higher in such cases.

The findings were reported in Proceedings of the National Academy of Sciences Online Early Edition.

The study’s corresponding author, Dr. Yehia Daaka, Distinguished Chair in Oncologic Pathology in the MCG School of Medicine, said that an increase in the volume of androgen receptors is considered to be behind prostate cancer progression in men with advanced complication.
