Dataset notes
Sample information and limitations One selected histone SILAC acquisition, H=25 mM glucose and L=0 mM glucose, mixed 1:1; independent biological n unspecified. Nine LFQ acquisitions are three enrichment classes with R1-R3 each, with biological/technical independence unspecified; they do not establish glucose-response replicates.
Experimental metadata notes Selected histone SILAC: 25 mM versus 0 mM glucose for 24 h, heavy=25 mM and light=0 mM; high/no-glucose response=H/L. Nine other label-free files represent Kce, KD-la and KL-la enrichment classes, not glucose treatment groups. A separate whole-cell comparison used 0.1 versus 25 mM glucose.
