Figure 4. Modulation of AR and PSA proteins with Rosemary extract.

Figure 4

A) 22Rv1 and LNCaP cells were treated with Rosemary Extract standardized to 40% carnosic acid (RE-40) for 24 hrs and cell lysates used to evaluate protein expression of AR by Western blot. B) Effect of RE-40 on PSA production in LNCaP cells after 24hrs was detected by ELISA. Columns, results are representative of experiments performed in six replicates; bars, SD. ***P<0.001, RE-40 treated sample versus control.
