A. Immunoblots of p75NTR levels with corresponding α-actin loading controls in PC-3 and DU-145 prostate cancer cells, T24 bladder cancer cells, MCF-7 breast cancer cells and 3T3 fibroblasts after 48 hour treatment with 0, 20, 40, 60, 80 and 100 M carprofen. A875 cell lysates were used as positive controls (+ve) for p75NTR expression. B. A MTT cell survival assay of PC-3 and DU-145 prostate cancer cells, T24 bladder cancer cells, MCF-7 breast cancer cells and 3T3 fibroblasts following 48 hour treatment with 0, 20, 40, 60, 80 and 100 μM carprofen. *p<0.01
