Figure 8. Haematopoietic PARP14 in mouse atheromata and PARP9–PARP14 expression in human plaques.

Figure 8

(a) Representative image and quantification of aortic root lesion formation and CD68+ macrophage accumulation (green, Alexa 488) in high-fat and high-cholesterol diet-fed LDLR−/− mice whose bone marrow was reconstituted by PARP14−/− mice (BMTPARP14−/−→LDLR−/− mice, n=5), compared with LDLR−/− mice with PARP14+/+ bone marrow (BMTPARP14+/+→LDLR−/− mice, n=6–7). Scale bars, 100 μm. (b) mRNA expression of the aorta from a. n=6–8. (c) Immunofluorescence staining of PARP14 and PARP9 proteins (green, Alexa 488) in human carotid plaques. CD68 (red, Alexa 594). Nuclei (blue, 4,6-diamidino-2-phenylindole, DAPI). Scale bars, 100 μm; insets, 10 μm (n=5). Prevalence of PARP14+ or PARP9+ macrophages in macrophage-poor versus macrophage-rich plaques. *P<0.05 and **P<0.01, respectively, by Student's t-test. Error bars indicate s.d.
