PUFA modulation of LAPC-4 proliferation. Cells were propagated on medium containing 10% FBS. Monolayers were harvested, and cells were plated (5 x 103 cells/well and considered as 100% cells) in 96-well plates on a medium either containing different concentrations (0–300 µM) or lacking (control) EPA (△-△), DHA (●-●), EPA + DHA (◆-◆), and 15-HEPE (□-□). Viable cell content was determined by quantification of formazan production. For clarity, SD error bars from the mean of quadruplicate wells (SD ≤ 10% of the mean) have been omitted.
