Intracellular phosphorylation profiles of N-MCT in KSHV-infected BCBL-1 cells (A) and uninfected CEM-SS cells (B) with (solid lines) and without (dotted lines) PMA stimulation. Shown are the levels of mono-, di-, and triphosphorylated N-MCT metabolites. The data shown are representative of two independent experiments. Compounds: (▪, □) N-MCT-MP; (▴, ▵) N-MCT-DP; (•, ○) N-MCT-TP in PMA-stimulated and unstimulated cells, respectively.
