<b>Polar metabolite data</b>Polar metabolite profiling data were generated for a mouse KGC pancreatic tumor line expressing doxycycline-inducible constitutively-active<b> </b>mutant GNAS (GNAS^R201C) growing in 2D culture in the presence of doxycycline; Dox(+) or absence of doxycycline; Dox(-). The cells were harvested as 5 biological replicates and flash-frozen. The polar metabolites were extracted with 40:40:20 acetonitrile/methanol/water and replicates are denoted as Dox(+)-1, Dox(+)-2, Dox(+)-3, Dox(+)-4, Dox(+)-5 and Dox(-)-1, Dox(-)-2, Dox(-)-3, Dox(-)-4, Dox(-)-5. Polar metabolites were analyzed by QQQ-LC/MS/MSas described in the reference^1.The ion counts were normalized to the total cell number. Metabolites were quantified by integrating the area under the curve, and then normalized to internal standard values.  1) Louie, S.
