Fatty acid binding protein 4 in circulating leucocytes reflects atherosclerotic lesion progression in Apoe(-/-) mice.
Bottom Line: Interestingly, the transcript FABP4 correlated significantly with lesion size, further supporting a disease associated increase.Using human circulating leucocytes, we confirmed the presence of FABP4 protein in neutrophils and monocytes.In conclusion, we have showed that cellular levels of FABP4 in circulating leucocytes associate with lesion development in the experimental Apoe(-/-) model.

Mentions: Gene expression profiles in leucocytes from atherosclerotic Apoe−/− mice were analysed to identify if any atherosclerosis-related changes could be detected in circulating cells. The atherosclerotic mice were investigated at three different time-points, 12, 20 and 32 weeks of age, to cover different stages of plaque development. To adjust for any changes correlating to ageing rather than atherosclerosis, the non-atherosclerotic C57BL/6 mouse was used as control. When comparing the transcript profiles between Apoe−/− and control mice, we revealed FABP4 to be the most changed transcript in the circulating leucocytes (Fig. 1A). The transcript level of FABP4 between young (8 weeks old) Apoe−/− and control mice did not differ, as measured by real-time RT-PCR (Fig. 1B). Neither, ALT, CKMB or CRSC differed between the mice groups, indicating normal status of liver, heart and kidney (data not shown).
