Abstract
AIMS Since desmin expression is diminished in vascular smooth muscle cells during reparative processes, we wanted to study whether a common intragenic single nucleotide polymorphism at nucleotide position 828 (rs1058261) of the DES gene associates with hypertension, cerebrovascular complications, and all cardiovascular events in the Tampere adult population cardiovascular risk (TAMRISK) study. MATERIALS AND METHODS A Finnish periodic health examination cohort of 336 subjects with diagnosed hypertension and 473 controls were analyzed. Samples were genotyped for polymorphism using TaqMan techniques. Prevalence of ischemic heart diseases, incidence of cerebrovascular diseases, and transient cerebral ischemic attacks (TIAs) were obtained by self-report and the National Hospital Discharge Registry (HILMO). RESULTS There was no association of any of the rs1058261 genotypes with hypertension at the age of 50. When the subjects were followed to the age of 60, after adjustment for gender and body mass index, subjects with the genotype CC had higher incidence of cerebrovascular events (cerebrovascular diseases and TIA) (4.1%) compared with the T allele (1.6%) (p = 0.046). In addition, those with CC genotype had a higher incidence of all combined cardiovascular events (12.8%) compared with subjects with the T allele (8.5%) (p = 0.028). CONCLUSIONS Our findings suggest that variations in the DES gene may be involved in cardiovascular disease.

Abstract
Hypoxia contributes to the phenotypic switch of vascular smooth muscle cells (VSMCs). Various microRNAs (miRNAs) participate in this process as post‑transcriptional regulators, however the mechanism remains unclear. In the present study, mouse VSMCs (mVSMCs) harvested from aortas were cultured in normoxic and hypoxic conditions, and the mRNA levels of miR-26b-5p, desmin, H‑caldesmon and smoothelin were quantified using reverse transcription‑quantitative polymerase chain reaction. Following treatment with a miR‑26b‑5p antagonist (agomir) or non‑targeting control (scramble), the cell areas of normoxic and hypoxic mVSMCs were analyzed by immunofluorescence staining. In addition, the protein expression levels of collagen Iα, Smad2/phosphorylated (p)‑Smad2, Smad3/p‑Smad3 and Smad4 were determined by western blotting. Potential miRNA26b‑5p binding sequences in the 3'‑untranslated region (UTR) of Smad4 were investigated, and the distribution of Smad4 in mVSMCs was visualized using immunofluorescence methods. Hypoxic mVSMCs exhibited a significant downregulation miR‑26b‑5p, upregulation of hypoxia inducible factor‑1α mRNA and suppression of desmin, H‑caldesmon and smoothelin mRNA levels. Additionally, miR‑26b‑5p agomir reduced the cell area and decreased collagen Iα expression levels in hypoxic mVSMCs compared with normoxic mVSMCs transfected with agomir, and the area was comparable with those of normoxic mVSMCs transfected with agomir or scramble. Furthermore, miR‑26b‑5p suppressed Smad4 expression in hypoxic mVSMCs, but did not change the expression levels of Smad2 and Smad3, p‑Smad2 and p‑Smad3, however p‑Smad2 and p‑Smad3 levels were upregulated in response to hypoxic stimuli. Additionally, the miR‑26b‑5p agomir caused weak immunoreactivity with Smad4 in hypoxic mVSMCs. The binding motif of miR‑26b‑5p in the Smad4 3'‑UTR was identified as UACUUGA at position 978-984. These findings suggest that miR‑26b‑5p regulates hypoxia‑induced phenotypic switching of VSMCs via the transforming growth factor β/Smad4 signaling pathway.

Abstract
Vascular smooth muscle cells (vSMCs) can switch between a contractile (differentiated) and a synthetic (dedifferentiated) phenotype. Synthetic, proliferative vSMCs are observed during embryogenesis, wound repair, and tissue engineering. The potential of isolated vSMCs to reverse this phenotypic modulation depends strictly on culture conditions. Previous studies have demonstrated that applied shear stress is an important signal for vSMC phenotype. The objective of this study was to determine whether applied shear stress is capable of triggering re-differentiation of vSMCs in tissue-engineered aortas. vSMCs were isolated from ovine arteries. Cells were cultured statically or exposed to two- (2D) and three-dimensional (3D) shear stress after seeding on a tubular matrix. For 3D in vivo testing, grafts were seeded additionally with endothelial cells and implanted in the descending aorta. Particular attention was paid to the expression pattern of vSMC markers, cell ultra-structure, matrix remodeling activity, and proliferative activity. Cultured vSMCs de-differentiated during static in vitro culture, but 2D and 3D in vitro shear stress promoted re-expression of vSMC markers. During in vivo culture, vSMCs progressed toward a fully differentiated phenotype. Cells were expressing markers of differentiated vSMCs and resembled a morphologically contractile vSMC phenotype. Matrix remodeling activity and proliferative activity decreased. This study demonstrates the phenotypic plasticity of vSMCs and their ability to return to a differentiated phenotype under shear stress conditions. These results are crucial for tissue engineering of blood vessels, because they indicate for the first time the in vitro potential to regain physiological functionality of isolated vSMCs.

Abstract
BACKGROUND Whether a hypoplastic transverse arch will grow after successful coarctectomy remains controversial. METHODS We studied 15 coarctation specimens with hypoplastic transverse arch. Eight patients were less than 1 month old and 7 were between 1 and 3 months. The diameter and length of the various segments of the aortic arch were measured. The number of elastin lamellae was determined histologically. Collagen density was quantified with a microdensitophotometer. Using immunohistochemistry, we determined alpha-actin-positive smooth muscle cells in the media of the ascending aorta and the hypoplastic transverse arch. RESULTS Despite a hypoplastic transverse arch, the ascending and descending aorta grew. The absolute number of elastin lamellae in the hypoplastic transverse arch was low, but when expressed as a ratio versus its diameter, this number was high (p < 0.05). Collagen density showed high absolute values in the descending aorta. In the older group, 4 of 7 showed no staining for alpha-actin in the hypoplastic transverse arch, whereas under 1 month of age, only 2 of 8 cases were negative. CONCLUSIONS The hypoplastic transverse arch is characterized by a relatively high number of elastin lamellae. Fewer alpha-actin-positive cells in the hypoplastic transverse arch occur in older specimens, which could indicate a diminished potential growth.

Abstract
BACKGROUND The cytoskeleton of cells in blood vessel walls contains desmin, vimentin, and cytokeratins. The distribution of these proteins in human vessels is not fully known. We have mapped the distribution of intermediate filament proteins in human arterial walls. METHODS Monoclonal antibodies targeted at the intermediate filament proteins desmin, vimentin, and cytokeratins were used, and the distribution of these proteins was studied by immunohistochemistry. RESULTS In the muscular arteries, most smooth muscle cells in the media expressed both desmin and vimentin; in the elastic arteries, the proportion of desmin-labelled cells was lower and preferentially located to the periphery of the media. In general, the desmin immunoreactivity within the intima was weak, but some smooth muscle cells and smooth muscle cells in the musculoelastic layer showed strong immunoreactivity. The vasa vasorum exhibited a heterogeneous desmin-labelling pattern. The vimentin antibodies labelled the endothelium and showed a heterogeneous staining pattern in the other layers of the arterial wall. Cytokeratin was detected in occasional cells in the media of muscular arteries, in many adluminal cells and cell clusters in the coronary intima, and in smooth muscle cells in the media of the elastic arteries. CONCLUSIONS Vimentin is widely distributed in vascular smooth muscle cells, whereas the distribution of desmin and cytokeratin varies. Each artery studied had an intermediate filament pattern typical for the anatomical location. There were no interindividual variations in the distribution of intermediate filament proteins.

Abstract
To understand the molecular mechanisms of cellular signaling of atrial natriuretic peptide (ANP), we have studied its effect on the enzymatic activity of endogenous and overexpressed protein kinase C (PKC) in rat thoracic aortic vascular smooth muscle (RTASM) cells. Angiotensin II (ANG II), endothelin-1 (ET-1), and 12-O-tetradecanoylphorbol 13-acetate (TPA) stimulated fourfold to fivefold PKC activity in PKC-alpha cDNA-transfected RTASM cells. However, pretreatment of these cells with ANP significantly inhibited the agonist-stimulated PKC activity in a dose-dependent manner. The inhibitory effect of ANP was more effective if cells were transfected with both PKC-alpha and guanylyl cyclase-A/atrial natriuretic peptide receptor (Npra) cDNAs. The agonist-stimulated PKC activity was also inhibited if RTASM cells were pretreated with cGMP analog 8-bromo-cGMP; however, the treatment of cells with a cAMP analog, dibutyryl-cAMP, did not show any discernible effect. The pretreatment of cells with Npra antagonist A-71915, significantly blocked the production of cGMP as well as the inhibitory effect of ANP on PKC activity. To further examine whether the antagonistic action of ANP and 8-bromo-cGMP on agonist-stimulated PKC activity were mediated through cGMP-dependent protein kinase (PKG), cells were treated with ANP or 8-bromo-cGMP and activators of PKC in the presence of KT-5823, a specific inhibitor of PKG. The treatment of cells with KT-5823 significantly attenuated the inhibitory effects of both ANP and 8-bromo-cGMP on agonist-stimulated PKC activity. The results from these studies provide strong evidence that ANP antagonizes the activation of PKC in RTASM cells, involving guanylyl cyclase-A receptor Npra and second messenger cGMP. Our data further support the notion that ANP acts as a negative mediator of signaling cross-talks between Npra and PKC in a cGMP-dependent manner, probably involving cGMP-dependent protein kinase in this process.

Abstract
Cellular composition of aortas from 5- to 12-week and 18- to 28-week-old human embryos were investigated using immunocytochemistry, scanning and transmission electron microscopy. The aorta of the 5- to 12-week-old embryos consisted of three sublayers differing in cellular composition. The inner sublayer adjacent to the endothelium contained round and ovoid cells with synthetic phenotype. In the intermediate sublayer, spindle-like cells ultrastructurally similar to smooth muscle cells were found. Cells of the outer sublayer resembled fibroblasts or poorly differentiated mesenchymal cells. There were not definite morphological borders between sublayers. In the 18- to 28-week-old embryo aorta the intima was separated from media by internal elastic lamina. Intimal and innermost medial cells had predominately stellate shape and synthetic phenotype. The outer part of media contained spindle-like cells that had well developed contractile structures. Both the 5- to 12-week-old and the 18- to 28-week-old embryo aortic cells were positively stained for alpha-actin and myosin and negatively stained for macrophage antigens. Thus, the majority of embryo aortic cells appeared smooth muscle cells, however there was a regional difference in shape and synthetic state of these cells.

Abstract
One of the key features of atherosclerosis formation and progression is 'dedifferentiation' of contractile arterial smooth muscle cells (SMC) in synthetic cells. In primary cultures and subcultures before 10 and after 200 passages, SMC exhibit contractile-like, synthetic and transformed phenotypes, respectively, providing a good model for studying dedifferentiation process in vitro: the rationale for comparing these phenotypes of SMC in vivo rests in similar changes in cytoenzymatic and cytoskeletal features. In vivo, dedifferentiated SMC are transformed into foam cells by accumulating lipids. Thus, the aim of this study was to determine whether cholesterol metabolism undergoes changes in dedifferentiated cells and the three cultured phenotypes were compared in regard to their cholesterol efflux mechanisms. Phenotypic changes were shown to be associated with decrease in intracellular cholesterol apoprotein mediated efflux and translocation but also with decrease in high affinity binding sites for native HDL. Thus, the dedifferentiation process triggers a need for increased supply of cholesterol for membrane synthesis and efflux down-regulation mechanisms are aimed at maximizing cholesterol availability to the cell. Plasma membrane cholesterol efflux, which seems to be apoprotein-independent, decrease slightly with cell dedifferentiation suggesting either modifications in the dedifferentiated cell membranes physical properties. Taken together, these different results showed that dedifferentiation of arterial SMC is associated with decrease in the different steps of the efflux process, which could constitute one of the early events in their foam cell transformation.

Abstract
The vascular wall of aorta and vena cava was examined for adenosine triphosphatase (ATPase) activity and cytoskeletal intermediate filaments (IF) in different representatives of vertebrates. Enzyme activity was studied by the modified method of Padykula and Herman. A streptavididin-biotin immunohistochemical method was applied to reveal desmin (D) and vimentin (V) IF. Endothelial cells of all vessels were V-positive and D-negative and exhibit high ATPase activity. Vascular smooth muscle cells (SMC) in lower vertebrates (pisces and amphibia) were also V-positive and D-negative, but showed low ATPase activity. SMC were D-positive and V-negative and possessed high enzyme activity in aves and mammals, similar to that of the endothelium. In cow vascular wall D-reactivity and high ATPase activity were mostly expressed in bundles of mosaically arranged thick SMC fibres of the outer aortic media as well as in the longitudinal fibres in the inferior vena cava. In higher vertebrates SMC of vasa vasorum were both V- and D-positive and showed high enzyme activity. The results demonstrate that D-immunoreactivity is mostly expressed in SMC of layers of high functional activity, which correlates with the intense ATPase reaction in these cells.

Abstract
Immunofluorescence-microscopy was applied to study the distribution of desmin, vimentin, and smooth muscle myosin in smooth muscle of human fetal vessels. Serial cryostat sections of the vessels examined all reacted positively with myosin and vimentin antibodies. However, heterogeneous staining of the vessels with desmin antibodies was observed. Thus, 2 types of smooth muscle staining were documented--desmin-negative and desmin-positive. Elastic and muscular arteries of the fetus (aorta, femoral and branchial artery) were desmin-negative while femoral and branchial veins were desmin-positive. In umbilical cord arteries and veins, the distribution of desmin-positive cells was largely localized to the outer layer of media, but not to the inner layer. In placenta, both desmin-positive and desmin-negative vessels were also revealed. Thus, differences in desmin expression by human vascular smooth muscle cells already exists during early stages of ontogeny.

Abstract
Cytoskeletal proteins are used as differentiation markers of vascular smooth muscle cells (SMC). To study possible changes in SMC phenotype during aging, cytoskeletal and cytocontractile proteins were quantified in the aortic intima-medias of 4-, 12-, 30-, and 36-month-old rats by one- and two-dimensional gel electrophoresis. The percentages of myosin and desmin in total protein decreased with age, while those of actin and vimentin remained unchanged. Immunohistochemical comparison of the aortas from 4- and 30-month-old rats showed that the reduction of desmin reflected a selective disappearance of desmin in some cells. There was an age-related increase in the proportion of beta-actin at the expense of the alpha-isoform. Our results suggest an age-dependent modulation of the phenotype of vascular SMC towards the synthetic state, which is opposite to that observed during developmental differentiation.
