Figure 1. PDAC cells exhibit an increased in vitro glutamine uptake.

(A-F) Glutamine uptake was evaluated as the amount of 2-¹⁵N-Gln lasting in culture media from 0 to 120 min. The uptake is expressed as % of glutamine in culture medium. Results are represented as mean±SEM of triplicates of two independent experiments. SEM less than 10% of the value is not visible in the graph. Curves were compared by two-way ANOVA, ^*** P <.001.
