Approach and Results: We investigated major adverse cardiac event during 10 years after 6-month intravascular ultrasound examination using our previous studies database. A total of 732 patients treated with bare-metal stent (54 LASM versus 678 non-LASM) and 529 patients treated with first-generation drug-eluting stent (82 LASM versus 447 non-LASM), who did not have clinical event or censoring at the time of follow-up intravascular ultrasound, were included for the present analysis. major adverse cardiac event was defined as the composite of cardiac death, target vessel-related myocardial infarction, target lesion revascularization and stent thrombosis. Multivariable adjustment and inverse probability weight were performed to consider baseline differences. After multivariable adjustment, LASM was related to a greater risk of major adverse cardiac event (hazard ratio, 1.666 [95% CI, 1.041-2.665]; P=0.0333) and very-late stent thrombosis (hazard ratio, 3.529 [95% CI, 1.153-10.798]; P=0.0271) than non-LASM in patients treated with first-generation drug-eluting stent, but not in those treated with bare-metal stent. Results were consistent after inverse probability weight. Among patients with LASM of first-generation drug-eluting stent, no late stent thrombosis occurred in patients who continued to receive dual antiplatelet therapy.\u0000\u0000\u0000CONCLUSIONS\u0000The relationship between LASM and major adverse cardiac event might depend on the type of implanted stents during the long-term follow-up, highlighting the clinical significance of polymers and drugs in drug-eluting stent system.","PeriodicalId":8404,"journal":{"name":"Arteriosclerosis, Thrombosis, & Vascular Biology","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87518046","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Distribution of fat is important for cardiometabolic health, with peripheral fat depots having a protective effect and central visceral fat depots conferring a detrimental effect on health. There are important sex differences in fat distribution that are masked when studying body mass index as a measure of obesity. From epidemiological, murine, and in vitro studies, several mechanisms have been proposed to explain the sex differences in adipose distribution, including sex hormonal effects, cell-intrinsic properties, and the microenvironment in fat depots. More recently, human genetics have revealed hundreds of loci for central obesity providing disruptive opportunities for mechanistic discoveries and clinical translation. A striking feature is that over one-third of these loci have reproducible but poorly understood sexual dimorphic associations with central obesity, most having stronger effects in women. Understanding the genetic and molecular mechanisms of adipose distribution and its sexual dimorphism in humans provides a unique opportunity to advance mechanism-based, sex and gender aware, precision medicine for early identification of at-risk individuals, as well as novel therapeutic strategies for central obesity and cardiometabolic disorders.","PeriodicalId":8404,"journal":{"name":"Arteriosclerosis, Thrombosis, & Vascular Biology","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84633949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, little is known about the effect and molecular mechanism of S-nitrosylation (SNO) modifications in TAD formation. Approach and Results: SNO levels were higher in aortic tissues from TAD patients than in those from healthy controls, and PLS3 (plastin-3) SNO was identified by liquid chromatography-tandem mass spectrometry analysis. Furthermore, tail vein administration of endothelial-specific adeno-associated viruses of mutant PLS3-C566A (denitrosylated form) suppressed the development of TAD in mice, but the wild-type PLS3 (S-nitrosylated form) virus did not. Mechanistically, Ang II (angiotensin II)-induced PLS3 SNO enhanced the association of PLS3 with both plectin and cofilin via an iNOS (inducible nitric oxide synthase)-dependent pathway in endothelial cells. The formation of PLS3/plectin/cofilin complex promoted cell migration and tube formation but weakened adherens junction formation in Ang II-treated endothelial cells. Interestingly, denitrosylated form of PLS3 partially mitigated Ang II-induced PLS3/plectin/cofilin complex formation and cell junction disruption. Additionally, the inhibition of iNOS attenuated PLS3 SNO and the association of PLS3 with plectin and cofilin, thereby modulating endothelial barrier function.\u0000\u0000\u0000CONCLUSIONS\u0000Our data indicate that protein SNO modification in endothelial cells modulates the progression of aortic aneurysm and dissection. The iNOS-mediated SNO of PLS3 at the Cys566 site promoted its interaction with cofilin and plectin, thus contributing to endothelial barrier disruption and pathological angiogenesis in TAD.","PeriodicalId":8404,"journal":{"name":"Arteriosclerosis, Thrombosis, & Vascular Biology","volume":"63 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87514136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Genome-wide association studies of coronary artery disease have identified several tightly linked, common intronic risk variants in LIPA which unexpectedly associate with increased mRNA expression. However, an exonic variant (rs1051338 resulting in T16P) in linkage with intronic variants lies in the signal peptide region and putatively disrupts trafficking. We sought to functionally investigate the net impact of this locus on LIPA and whether rs1051338 could disrupt LIPA processing and function to explain coronary artery disease risk. Approach and Results: In monocytes isolated from a large cohort of healthy individuals, we demonstrate both exonic and intronic risk variants are associated with increased LIPA enzyme activity coincident with the increased transcript levels. To functionally isolate the impact of rs1051338, we studied several in vitro overexpression systems and consistently observed no differences in LIPA expression, processing, activity, or secretion. Further, we characterized a second common exonic coding variant (rs1051339), which is predicted to alter LIPA signal peptide cleavage similarly to rs1051338, yet is not linked to intronic variants. rs1051339 also does not impact LIPA function in vitro and confers no coronary artery disease risk.\u0000\u0000\u0000CONCLUSIONS\u0000Our findings show that common LIPA exonic variants in the signal peptide are of minimal functional significance and suggest coronary artery disease risk is instead associated with increased LIPA function linked to intronic variants. Understanding the mechanisms and cell-specific contexts of LIPA function in the plaque is necessary to understand its association with cardiovascular risk.","PeriodicalId":8404,"journal":{"name":"Arteriosclerosis, Thrombosis, & Vascular Biology","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82286032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
