Abstract
Appendage patterning and evolution have been active areas of inquiry for the past two centuries. While most work has centred on the skeleton, particularly that of amniotes, the evolutionary origins and molecular underpinnings of the neuromuscular diversity of fish appendages have remained enigmatic. The fundamental pattern of segmentation in amniotes, for example, is that all muscle precursors and spinal nerves enter either the paired appendages or body wall at the same spinal level. The condition in finned vertebrates is not understood. To address this gap in knowledge, we investigated the development of muscles and nerves in unpaired and paired fins of skates and compared them to those of chain catsharks. During skate and shark embryogenesis, cell populations of muscle precursors and associated spinal nerves at the same axial level contribute to both appendages and body wall, perhaps representing an ancestral condition of gnathostome appendicular neuromuscular systems. Remarkably in skates, this neuromuscular bifurcation as well as colinear Hox expression extend posteriorly to pattern a broad paired fin domain. In addition, we identified migratory muscle precursors (MMPs), which are known to develop into paired appendage muscles with Pax3 and Lbx1 gene expression, in the dorsal fins of skates. Our results suggest that muscles of paired fins have evolved via redeployment of the genetic programme of MMPs that were already involved in dorsal fin development. Appendicular neuromuscular systems most likely have emerged as side branches of body wall neuromusculature and have been modified to adapt to distinct aquatic and terrestrial habitats.

Abstract
BACKGROUND Peripheral artery disease (PAD), a diffuse manifestation of atherothrombosis, is a major cardiovascular threat. Although platelets are primary mediators of atherothrombosis, their role in the pathogenesis of PAD remains unclear. OBJECTIVES The authors sought to investigate the role of platelets in a cohort of symptomatic PAD. METHODS The authors profiled platelet activity, mRNA, and effector roles in patients with symptomatic PAD and in healthy controls. Patients with PAD and carotid artery stenosis were recruited into ongoing studies (NCT02106429 and NCT01897103) investigating platelet activity, platelet RNA, and cardiovascular disease. RESULTS Platelet RNA sequence profiling mapped a robust up-regulation of myeloid-related protein (MRP)-14 mRNA, a potent calcium binding protein heterodimer, in PAD. Circulating activated platelets were enriched with MRP-14 protein, which augmented the expression of the adhesion mediator, P-selectin, thereby promoting monocyte-platelet aggregates. Electron microscopy confirmed the firm interaction of platelets with monocytes in vitro and colocalization of macrophages with MRP-14 confirmed their cross talk in atherosclerotic manifestations of PAD in vivo. Platelet-derived MRP-14 was channeled to monocytes, thereby fueling their expression of key PAD lesional hallmarks and increasing their directed locomotion, which were both suppressed in the presence of antibody-mediated blockade. Circulating MRP-14 was heightened in the setting of PAD, significantly correlated with PAD severity, and was associated with incident limb events. CONCLUSIONS The authors identified a heightened platelet activity profile and unraveled a novel immunomodulatory effector role of platelet-derived MRP-14 in reprograming monocyte activation in symptomatic PAD.

Abstract
Abdominal aortic aneurysms (AAA) are characterized by extensive extracellular matrix (ECM) fragmentation and inflammation. However, the mechanisms by which these events are coupled thereby fueling focal vascular damage are undefined. Here we report through single-cell RNA-sequencing of diseased aorta that the neuronal guidance cue netrin-1 can act at the interface of macrophage-driven injury and ECM degradation. Netrin-1 expression peaks in human and murine aneurysmal macrophages. Targeted deletion of netrin-1 in macrophages protects mice from developing AAA. Through its receptor neogenin-1, netrin-1 induces a robust intracellular calcium flux necessary for the transcriptional regulation and persistent catalytic activation of matrix metalloproteinase-3 (MMP3) by vascular smooth muscle cells. Deficiency in MMP3 reduces ECM damage and the susceptibility of mice to develop AAA. Here, we establish netrin-1 as a major signal that mediates the dynamic crosstalk between inflammation and chronic erosion of the ECM in AAA. Abdominal aortic aneurysms (AAA) are characterized by extensive extracellular matrix degradation. Here Hadi et al. identify a netrin-1/neogenin-based crosstalk between macrophages and vascular smooth muscle cells (VSMCs), leading to the secretion of the matrix metalloproteinase MMP-3 by VSMCs and subsequent matrix degradation in AAA lesions.

Abstract
Objective:
To determine whether monocyte-platelet aggregates (MPA) correlate with aortic aneurysm (AA) prevalence and severity.
BACKGROUND:
Inflammation and intraluminal thrombus are key hallmarks of complex AA. While monocytes fuel inflammation in AA, the contribution of platelets is unknown. We hypothesized that increased platelet activity yields to MPA that drive AA development and indicate disease severity.
Methods:
Blood was collected from 49 symptomatic patients admitted for aneurysm repair procedures (8 thoracic and 41 abdominal) and 36 matched controls. All subjects were on aspirin monotherapy. Platelet responsiveness to agonists was characterized by light transmission aggregometry. Flow cytometry analysis allowed leukocytes (CD45+)/monocytes (CD14+)-platelet (CD61+) aggregates (LPA/MPA) measurements in the blood and profiled MPA in post-surgical aneurysm tissues.
Results:
Platelet aggregation in response to ADP (57% vs. 35% aggregation, p<0.001) and arachidonic acid (24% vs. 16% aggregation, p=0.03), was increased in patients with AA versus controls. LPA (17.7 vs 6.2% CD61+ leukocytes, p=0.002) and MPA (18.0 vs 7.2% CD61+ Monocytes, p=0.008) were robustly increased in AA vs controls. MPA but not LPA was strongly and positively associated with AA size (p<0.0001). To delve into the role of MPA
in situ
in AA sac, platelets and tissue macrophage activation was characterized. Compared to the non-diseased part of the aorta, diseased section had significantly higher platelet infiltration (7.0% vs 1.2% CD61+ cells, p=0.006) and interaction with CD68+ tissue macrophages (8.3% vs. 0.7%, CD61+ macrophages p=0.03). Notably, macrophages highly expressed the adhesion protein, ICAM-1, in the diseased part (39.6 vs 3.3% in the non-diseased section, p<0.001) which further increased to 69.4% (p=0.01) when macrophages were in contact with platelets.
Conclusions:
Our data highlights MPA as a novel mediator valuable to predict AA prevalence and severity.

Abstract
The role of Asn-linked oligosaccharide in the functional properties of both human tissue-type plasminogen activator (t-PA) and a genetic variant of t-PA was studied. Nonglycosylated and glycosylated wild-type t-PA were produced in mammalian cells which express recombinant t-PA. These proteins were compared in fibrin binding and 125I-labeled fibrin clot lysis assays, using purified components. The nonglycosylated form showed higher fibrin binding, as well as higher fibrinolytic potency than the glycosylated form. Subsequently, prevention of glycosylation of a t-PA variant which lacked the finger and epidermal growth factor domains (delta FE), was carried out in an attempt to enhance its fibrinolytic activity. Glycosylation was prevented by changing Asn to Gln; at Asn-117 to produce delta FE1X t-PA, and at Asn-117, -184, and -448 to produce delta FE3X t-PA. All variants were similar to wild-type t-PA in their catalytic dependence on fibrinogen fragments, fibrinolytic activity in fibrin autography analysis, and plasminogen activator activity. In a clot lysis assay, using citrated human plasma, the fibrinolytic potency of the variants were comparable to that of wild-type t-PA at activator concentrations of 17-51 nM (approximately 1-3 micrograms/ml). At 0.5-5.1 nM (approximately 0.03-0.3 micrograms/ml), however, the variant proteins had lower fibrinolytic potency than wild-type t-PA. Fifty percent lysis in 1.5 h for wild-type, delta FE, delta FE1X, and delta FE3X t-PA, required 2.5, 10, 7.5, and 5.5 nM t-PA, respectively. The fibrinogenolytic activity in human plasma was measured for wild-type, delta FE, delta FE1X, and delta FE3X t-PA, and showed significant fibrinogen depletion after 3 h of incubation at 51 nM, decreasing to 11, 11, 50, and 72% of basal levels, respectively. These data indicate that partial or total nonglycosylated t-PA variants have a higher fibrinolytic versus fibrinogenolytic ratio than their fully glycosylated counterparts.

Abstract
The synthesis and mutagenicity of two derivatives of 7,12-dimethylbenz[a]anthracene (DMBA; 1), i.e., 1,2-H2DMBA (4) and 1,2,3,4-H4DMBA (5), are reported. These analogues (4 and 5) represent dihydro and tetrahydro A-ring reduced forms of DMBA, a region in the parent hydrocarbon (1) proposed to be involved in metabolism to the ultimate carcinogen. The synthesis for 4 without isolation of intermediates from the tosylhydrazone of 1,2,3,4-tetrahydrobenz[a]anthracene-4,7,12-trione (10) by successive reaction with 8 molar equiv of CH3Li, HI, and NaBH4 represents a novel approach to this hydrocarbon now available in sufficient quantity for biological studies. Interestingly, both of these reduced analogues 4 and 5 exhibited mutagenic activity in the Ames assay in the presence or absence of microsomal activation for strains TA98 and TA100. In these strains, DMBA was active only in the presence of S-9 fraction. In the plasmid-deficient strain TA1537, only tetrahydro analogue 5 exhibited mutagenic activity both in the absence and presence of S-9 fraction.
