However, the outcomes of ITT showed that the glucose-lowering effect of insulin was substantially impaired in Agtrap??mice on HFD compared with WT Agtrap+/+ mice (relative glucose level; SD, 41.eight?.3 versus 26.9?.0 , F=1.247, P=0.290; HFD, 52.7?.0 versus 42.three?.5 , F=7.200, P=0.016) (Figure 5B). These results help the conclusionDOI: ten.1161/JAHA.113.that ATRAP deficiency is closely associated with insulin resistance.ATRAP Deficiency Exacerbates Inflammatory Responses in Adipose Tissue in Response to HF LoadingWe investigated doable alterations in adipocytokine production and identified that the HF loading ediated upregulation of MCP-1, a important player within the inflammatory course of action,25,26 was exacerbated within the adipose tissue of Agtrap??mice compared with WT Agtrap+/+ mice (Figure 6A). On the other hand, the HF loading ediated increase in IL-6 expression did not attain the statistical significance inside the adipose tissue of Agtrap??mice and no significant alterations were observed in TNFa or PAI-1. Simply because MCP-1 contributes for the macrophage recruitment in inflamed adipose tissue, we subsequent examined macrophage-related gene expression and macrophage infiltration. We discovered that the expression patterns of CD68 and F4/80 have been considerably elevated within the adipose tissue of Agtrap??but not WT Agtrap+/+ mice on HFD (CD68, 1.54?.18 versus 0.87?.09 fold induction, P=0.001; F4/80, 1.73?.33 versus 1.01?.12 fold induction, P=0.013; Figure 6A). On immunohistochemical staining for F4/80-positive cells and its quantitative evaluation, there was an elevated accumulation of infiltrating macrophages in white adipose tissue with the Agtrap??mice on HF loading compared with WT Agtrap+/+ mice (Figure 6B). This finding is consistent with the upregulation of macrophage-specific genes (CD68, F4/80 in Figure 6A) within the adipose tissue of Agtrap??mice.
