SLC16A1 and diffuse large B-cell lymphoma: In this work, we investigated nutrient flux in a DLBCL model through radioactive uptake of exogenously labeled fuels—[18F]-S-FL, synthesized in our group, together with [18F]FDG, L-[1-13C]lactate and D-[13C6]glucose following treatment with MCT1 inhibitor, AZD3965.
