Essential Hypertension (EH) results in the burden of cardiovascular disease (CVD) such as Heart Failure (HF) and Ischemic Stroke (IS). A rapidly emerging field involving the role of Wnt/β-catenin signaling pathway in cardiovascular development and dysfunction has recently drawn extensive attention. In the present study, we conducted a genetic association between genomic variants in Wnt/β-catenin signaling pathway and EH, HF, IS. A total of 95 SNPs in 12 Wnt signaling genes (WNT3A, WNT3, WNT4, DKK1, DKK2, LRP5, LRP6, CTNNB1, APC, FZD1, FRZB, SFRP1) were genotyped in 1,860 participants (440 patients with EH, 535 patients with HF, 421 patients with IS and 464 normal control subjects) using Sequenom MassArray technology. WNT3A rs752107(C > T) was strongly associated with an increased risk of EH, HF and IS. Compared with WNT3A rs752107 CC genotype, the CT genotype carriers had a 48% increased risk of EH (OR = 1.48, 95% CI = 1.12–1.96, P = 0.006), the TT genotype conferred a 139% increased risk of EH (OR = 2.39, 95% CI = 1.32–4.34, P = 0.003). Regarding HF and IS, the risk of HF in the T allele carriers (CT + TT) was nearly increased by 58% (OR = 1.58, 95% CI = 1.22–2.04, P = 4.40 × 10−4) and the risk of IS was increased by 37% (OR = 1.37, 95% CI = 1.04–1.79, P = 0.025). Expression quantitative trait loci (eQTL) analysis indicated that rs752107 C allele corresponded to a significant reduction of WNT3A expression. We described a genetic variant of WNT3A rs752107 in Wnt/β-catenin signaling strongly associated with the risk of EH, HF and IS for the first time.

Abstract Background Thoracic aortic diameters have been associated with cardiovascular risk factors and atherosclerosis. However, limited evidence regarding the role of thoracic aortic diameters as risk markers for major cardiovascular outcomes among women and men exist. Purpose To evaluate the independent associations between crude and indexed ascending and descending aortic (AA and DA) diameters with major cardiovascular outcomes among women and men and to provide optimal cutoff values associated with increased cardiovascular risk. Methods and results 2178 women and men ≥55 years from the prospective population-based Rotterdam Study underwent multi-detector CT scan of thorax. Crude diameters of the AA and DA were measured and indexed by height, weight, body surface area (BSA) and body mass index (BMI). Incidence of stroke, coronary heart disease (CHD), heart failure (HF), cardiovascular and all-cause mortality were evaluated during 13 years of follow-up. Weight-, BSA-, or BMI-indexed AA diameters showed significant associations with total or cardiovascular mortality in both sexes and height-indexed values showed association with HF in women. Crude AA diameters were associated with stroke in men and HF in women. For DA, crude and almost all indexed diameters showed significant associations with either stroke, HF, cardiovascular or total mortality in women. Only weight-, BSA- and BMI-indexed values were associated with total mortality in men. For crude DA diameter, the risk for stroke increased significantly at the 75th percentile among men while the risks for HF and cardiovascular mortality increased at the 75th and 85th percentiles respectively in women. Conclusions Our study suggests a role for descending thoracic aortic diameter as a marker for increased cardiovascular risk, in particular for stroke, heart failure and cardiovascular mortality among women. The cut points for increased risk for several of cardiovascular outcomes were below the 95th percentile of the distribution of aortic diameters.

Abstract Aims Obesity is associated with increased risk for heart failure. We analysed data from the Swedish Obese Subjects (SOS) study, a prospective matched cohort study, to investigate whether bariatric surgery reduces this risk. Methods and results From the total SOS population (n = 4047), we identified 4033 obese individuals with no history of heart failure at baseline, of whom 2003 underwent bariatric surgery (surgery group) and 2030 received usual care (control group). First-time principal diagnoses of heart failure were identified by crosschecking the SOS database with the Swedish National Patient Register and the Swedish Cause of Death Register using diagnosis codes. During a median follow-up of 22 years, first-time heart failure occurred in 188 of the participants treated with surgery and in 266 of those receiving usual care. The risk of developing heart failure was lower in the surgery group than in the control group [sub-hazard ratio 0.65, 95% confidence interval (CI) 0.54–0.79; P < 0.001]. After pooling data from the two study groups, the quartile of subjects with the largest weight loss after 1 year (mean −41 kg) displayed the greatest risk reduction (sub-hazard ratio 0.51, 95% CI 0.30–0.70; P < 0.001). This association remained statistically significant after adjustment for surgical intervention and potential baseline confounders (sub-hazard ratio 0.60, 95% CI 0.36–0.97; P = 0.038). Conclusion Compared with usual care, bariatric surgery was associated with reduced risk of heart failure among persons being treated for obesity. The risk of heart failure appeared to decline in parallel with a greater degree of weight loss. ClinicalTrials.gov Identifier NCT01479452.

Diabetes patients have an increased risk of heart failure (HF). Diabetes is highly prevalent in HF with preserved ejection fraction (HFpEF), which is on the rise worldwide. The role of diabetes in HF is less established and available treatments of HF are not effective in HFpEF patients. Tissue factor (TF), a transmembrane receptor, plays an important role in immune-cell inflammation and atherothrombosis in diabetes. However, its role in diabetes-induced cardiac inflammation, hypertrophy, and HF has not been studied. Here, we have utilized Wildtype (WT), heterozygous, and Low-TF (with 1% human TF) mice to determine TF’s role in <i>Type1 diabetes</i>-induced HF. We found significant upregulation of cardiac TF mRNA and protein levels in diabetic WT hearts compared to non-diabetic controls. WT diabetic hearts also exhibited increased inflammation and cardiac hypertrophy versus controls. However, these changes in cardiac inflammation and hypertrophy were not found in diabetic Low-TF mice compared to their non-diabetic controls. TF deficiency was also associated with improved cardiac function parameters suggestive of HFpEF, which was evident in diabetic WT mice. The TF regulation of inflammation and cardiac remodeling was further dependent on downstream ERK1/2 and STAT3 pathways. In summary, our study demonstrated an important role of TF in regulating diabetes-induced inflammation, hypertrophy, and remodeling of the heart leading to HF with preserved ejection fraction.

Abstract Background Acromegaly is associated with an increased risk of fatal and non-fatal cardiovascular (CV) events. Controlling acromegaly decreases, but does not normalize this risk. Brain natriuretic peptide (BNP) assessment is used in the general population for the diagnosis of heart failure and to predict ischemic recurrences and mortality. This is a retrospective, longitudinal, monocenter study that evaluates the role of serum N-terminal fragment of BNP (NT-pro-BNP) for predicting CV events in acromegaly patients. Methods Serum NT-pro-BNP levels were measured in 76 patients with acromegaly (23 males, 57.7±1.5 years), and compared with other predictors of CV events. NT-pro-BNP cut-off value discriminating the occurrence of CV events was determined by ROC analysis. CV events were recorded during a follow-up of 78.6±6.4 months. Results CV events occurred in 9.2% of patients. Mean log(NT-pro-BNP) concentration was higher in patients who experienced CV events than in those who did not (p<0.01) and in patients who died due to CV events than in those who died due to other causes (p<0.01). Based on the ROC curve, a cut-off value of 91.55 pg/mL could predict CV events (OR 19.06). Log(NT-pro-BNP) was lower in surgically treated patients by surgery (p<0.05), and in those cured by neurosurgery (p<0.02). Conclusions High NT-pro-BNP value is an independent middle-term predictor of fatal or non-fatal CV events in patients with acromegaly. According to this parameter, surgically treated patients show lower CV risk than those managed with medical therapy, especially if the disease is cured.

Considering the pleiotropic roles of glutathione transferase (GST) omega class members in redox homeostasis, we hypothesized that polymorphisms in GSTO1 and GSTO2 might contribute to prostate cancer (PC) development and progression. Therefore, we performed a comprehensive analysis of GSTO1 and GSTO2 SNPs’ role in susceptibility to PC, as well as whether they might serve as prognostic biomarkers independently or in conjunction with other common GST polymorphisms (GSTM1, GSTT1, and GSTP1). Genotyping was performed in 237 PC cases and 236 age-matched controls by multiplex PCR for deletion of GST polymorphisms and quantitative PCR for SNPs. The results of this study, for the first time, demonstrated that homozygous carriers of both GSTO1*A/A and GSTO2*G/G variant genotypes are at increased risk of PC. This was further confirmed by haplotype analysis, which showed that H2 comprising both GSTO1*A and GSTO2*G variant alleles represented a high-risk combination. However, the prognostic relevance of polymorphisms in GST omega genes was not found in our cohort of PC patients. Analysis of the role of other investigated GST polymorphisms (GSTM1, GSTT1, and GSTP1) in terms of PC prognosis has shown shorter survival in carriers of GSTP1*T/T (rs1138272) genotype than in those carrying at least one referent allele. In addition, the presence of GSTP1*T/T genotype independently predicted a four-fold higher risk of overall mortality among PC patients. This study demonstrated a significant prognostic role of GST polymorphism in PC.

Previous studies have confirmed the clinical efficacy of sacubitril/valsartan (Sac/Val) for the treatment of heart failure with reduced ejection fraction (HFrEF). However, the role of Sac/Val in heart failure with preserved ejection fraction (HFpEF) remains unclear. Sac/Val is a combination therapeutic medicine comprising sacubitril and valsartan that acts as a first angiotensin receptor blocker and neprilysin inhibitor (angiotensin-receptor neprilysin inhibitor (ARNI)). Here, we investigated the role of Sac/Val in high-salt diet-induced HFpEF coupled with vascular injury as well as the underlying mechanism. Rats were fed with high-salt feed, followed by intragastric administration of Sac/Val (68 mg/kg; i.g.). The results of functional tests revealed that a high-salt diet caused pathological injuries in the heart and vascular endothelium, which were significantly reversed by treatment with Sac/Val. Moreover, Sac/Val significantly decreased the levels of fibrotic factors, including type I collagen and type Ⅲ collagen, thus, reducing the ratio of MMP2/TIMP2 while increasing Smad7 levels. Further investigation suggested that Sac/Val probably reversed the effects of high-salt diet-induced HFpEF by inhibiting the activation of the TGF-β1/Smad3 signaling pathway. Thus, treatment with Sac/Val effectively alleviated the symptoms of high-salt diet-induced HFpEF, probably by inhibiting fibrosis via the TGF-β1/Smad3 signaling pathway, supporting the therapeutic potential of Sac/Val for the treatment of HFpEF.

Abstract Background:Long noncoding RNAs (lncRNAs) can drive cancer progression. Here, we studied the role of a novel lncRNA, LINC01956, in glioblastoma (GBM). Methods:RT-PCR assay was used to examine LINC01956 expression levels. Colony-formation, MTT, cell-cycle and in-vivo tumorigenesis assays were used to examine the role of LINC01956 in cell growth in vitro and in vivo. Boyden assay was used to examine cell invasion ability in vitro. RNA immunoprecipitation and RNA-protein pull-down assays were used to examine the interaction between LINC01956 and FUS protein.ChIP assay was used to examine HIF1-binding sites in the LINC01956 promoter.Results:The level of LINC01956 was elevated in GBM cell lines and tissues. LINC01956 downregulation suppressed the migration and proliferation of GBM cells. M2 polarization of macrophages induced by exosomes derived from glioma cells overexpressing LINC01956 further accelerated GBM progression. Mechanistically, we found that FUS interacted with both LINC01956 and β-catenin. LINC01956 bound to FUS and reduced its ubiquitination. LINC01956 evoked nuclear translocation of phosphorylated (p)-β-catenin by recruiting FUS. Furthermore, under hypoxic conditions, LINC01956 was regulated by HIF-1α. Conclusion:Taken together, our data revealed for the first time that LINC01956 exerts protumor effects via FUS-dependent activation of the WNT/β-catenin signaling pathway.
