After WD feeding, Epac1–/–, but not Epac2–/–, mice had significantly higher mRNA levels of tumor necrosis factor-alpha (TNF-α) and F4/80 in the epididymal white adipose tissue (EWAT), increased circulating lipocalin-2 protein and more severe glucose intolerance, suggesting greater inflammation and insulin resistance in WD-fed Epac1–/– mice than corresponding WT mice. The gene discussed is LCN2; the disease is Glucose intolerance.
