Figure 3: A: Part of the purine metabolism pathway as depicted in the Small Molecule Pathway Database (SMPDB) (http://www.smpdb.ca/); B: The detailed changes of enzymes from the parallel transcriptomics analysis shown in Figure 4. AMP: adenosine monophosphate; ADP: adenosine diphosphate; ATP: adenosine triphosphate; IMP: inosine monophosphate; IDP: inosine diphosphate; ITP: inosine triphosphate; OB: diet-induced-obese (i.e. the OB-SC group and the OB-MS group); RW: regular weight (i.e. the RW-SC group and the RW-MS group); Ampd2: Adenosine monophosphate deaminase 2; Adat2: Adenosine deaminase, tRNA-specific 2.
