Article Title: Profiling of Atherosclerotic Lesions by Gene and Tissue Microarrays Reveals PCSK6 as a Novel Protease in Unstable Carotid Atherosclerosis
Journal: Arteriosclerosis, Thrombosis, and Vascular Biology
doi: 10.1161/atvbaha.113.301743
Figure Legend Snippet: Figure 1. Study design. Carotid plaques (n=34) from asymptomatic and symptomatic patients were sectioned at 2 levels and 3 cores drilled from each level (A) to construct 2 tissue microarray (TMA) blocks with 204 cores in total (B). Based on symptomatic vs asymptom- atic microarray comparisons generated for n=127 plaques (C), highly upregulated genes were chosen for the study (D; in red). Several genes already known to be associated with atherosclerosis were also included (D; in black). TMAs were stained by immunohistochemistry (IHC) with antibodies toward human proteins of interest, and tissue sections were scored (0, 1, 2, or 3) for semiquantitative grading of staining intensity (E). Significantly differentially expressed proteins were validated further by IHC on individual plaques (F).
Techniques Used: Construct, Microarray, Generated, Staining, Immunohistochemistry
![Figure 4. PCSK6 is the most significantly upregulated proprotein convertase (PC) in symptomatic carotid plaques. Analy- ses of n=127 microarray profiles between carotid plaques (CP) and normal controls (iliac arteries [IA]) show significant down- regulation of Furin and PCSK5 in plaque tissue, upregulation of PCSK6 and PCSK7, whereas PCSK9 and PCSK2 did not exhibit significant variation in expression (A). Posi- tive correlation was found between expres- sion of PCSK6 and PCSK9, PCSK2 and PCSK7, whereas negative was observed with PCSK5 (B). Several PCSK6 isoforms recognized by different Affymetrix probes were significantly upregulated in plaques compared with controls, but most highly the isoform coding for secreted protein (C). This isoform was the only one with signifi- cantly higher expression in comparison between symptomatic (s) and asymptom- atic (as) plaques (D). Results were con- firmed by quantitative real-time polymerase chain reaction (qRT-PCR) analyses for expression of secreted PCSK6 isoform in a separate cohort of n=233 carotid plaques (E and F). Micorarray data expressed as log2 value and qRT-PCR data as fold change compared with control. Data in A, C, and D show mean with SD, whereas median with interquartile range is depicted in E and F.
