Figure 2: LNCaP phenoxodiol / docetaxel isobologram measured after 48 hr of treatment. LNCaP cell proliferation was determined using an MTS assay following 48 hr docetaxel plus phenoxodiol treatment at various doses and combinations. * indicates significant increase in proliferation relative to (0 μM PXD, 100 nM DOC) treatment after 48 hr.
