Obesity is associated with altered serum concentrations of ATM-expressed factors. Serum protein concentrations of CXCL1, -2, -3 (Gro), CXCL6 (GCP-2), CXCL7 (NAP-2), CXCL9 (MIG), CXCL10 (IP-10), CXCL11 (I-TAC), CXCL16 (S-PROX), TGFβ1, and sgp130 were quantified in obese and lean subjects. Statistically significant differences are indicated (*, p < 0.05; **, p < 0.01).
