Preeclampsia is a pregnancy-specific disorder that is a major cause of maternal and foetal morbidity and mortality, with a prevalence of 6-8% of pregnancies. Although the downregulation of lysyl oxidase (LOX) and LOX-like protein 2 (LOXL2), which leads to reduced trophoblast cell migration and invasion through activation of the TGF-β1/Smad3/collagen pathway, is relevant to preeclampsia, the mechanisms regulating differences in the gene expression of LOX and LOXL2 in placentas are not yet understood. This study aimed to investigate the mechanisms regulating differences in the gene expression of LOX and LOXL2 in placentas.

The expression of miRNAs, LOX and LOXL2 in preeclamptic placentas and control placentas was analysed by qPCR. Localisation of miR29a and LOXL2 in preeclamptic placentas was performed by RNA-Fluorescence in-situ hybridization assay. The direct regulation of LOXL2 by miR-29a was assessed by dual-luciferase reporter assays in human extravillous trophoblast cells (HTR8/SVneo). Cell migration and invasion were evaluated by Transwell assays in HTR8/SVneo cells.

miR-29a expression was upregulated in preeclamptic placentas and negatively correlated with LOXL2 mRNA expression levels. selleckchem RNA-Fluorescence in-situ hybridization assay revealed a clear overlap between miR-29a and LOXL2 in the placentas of preeclampic women. LOXL2 was a direct target gene of miR-29a, as confirmed by a dual-luciferase reporter assay in HTR8/SVneo trophoblast cells. miR-29a suppressed HTR8/SVneo trophoblast cell migration and invasion. LOXL2 overexpression reversed the inhibitory effects of miR-29a on HTR8/SVneo trophoblast cell migration and invasion.

Our results suggest that the upregulation of miR-29a suppresses the migration and invasion of HTR8/SVneo trophoblast cells by directly targeting LOXL2 in preeclampsia.

Diet-induced and exercise-induced weight loss remains a key strategy to combat metabolic disorders, but is often difficult to achieve. Current pharmacological approaches result in variable responses in different patient cohorts and long-term efficacy may be limited by medication intolerance and nonadherence. A clinical need exists for complementary therapies to curb the burden of cardiometabolic diseases. One such approach may include interventional sympathetic neuromodulation of organs relevant to cardiometabolic control. The experience from catheter-based renal denervation studies clearly demonstrates the feasibility, safety and efficacy of such an approach. In analogy, denervation of the common hepatic artery is now feasible in humans and may prove to be similarly useful in modulating sympathetic overdrive directed towards the liver, pancreas and duodenum. Such a targeted multiorgan neuromodulation strategy may beneficially influence multiple aspects of the cardiometabolic disease continuum offering a holistic approach.
Aldosterone synthase gene, CYP11B2 is regulated by potassium and angiotensin II (Ang II). We have reported that Ang II could change the DNA methylation status around transcription factor-binding sites and a transcription start site (TSS) and activate expression of CYP11B2. Similar to Ang II, small increases in extracellular potassium levels also increase CYP11B2 mRNA levels.

Adrenocortical H295R cells were treated with different doses of potassium. Methylation analysis of CYP11B2 promoter region was done by bisulfite sequencing. CYP11B2 mRNA and protein levels, chromatin accessibility, methylation and demethylation activity were estimated. The transcriptional ability of CYP11B2 promoter with or without methylation was assessed. Potassium stimulation caused DNA demethylation around cyclic AMP responsive element binding protein 1 (CREB1) and nuclear receptor subfamily 4 group A (NR4A) family-binding sites and a TSS; demethylation was accompanied by recruitment of CREB1 and NR4A1 and increased chromatin accessibility of the CYP11B2 promoter. DNA methylation activity decreased in the nucleus. DNA demethylation at CpG1 (Ad1), CpG2 (Ad5) and CpG3 were detected within 2 to 4 days after potassium (16 mmol/l) stimulation. The changes reached a maximum level by day 7. DNA at CpG2 (Ad5) and CpG3 was re-methylated to levels that were similar to those of nontreated cells at day 9. Potassium treatment significantly reduced DNA methylation activity at days 7 and 9. DNA demethylation activity was not changed by potassium.

Potassium induced reversibly DNA demethylation, which switches the phenotype of CYP11B2 expression from an inactive to an active state.

In this large online survey of primarily men who have sex with men, those who used preexposure prophylaxis reported greater sexual satisfaction than did nonusers, including sexual sensations, sexual presence/awareness, and sexual exchange. Person-centered care and messaging may require acknowledging that some people use preexposure prophylaxis for reasons beyond HIV prevention.

Dislocation of the magnet inside the implanted component of a cochlear implant (CI) can be a serious risk for patients undergoing a magnetic resonance imaging (MRI) exam. CI manufacturers aim to reduce this risk either via the design of the implant magnet or magnet housing, or by advising a compression bandage and cover over the magnet. The aim of this study is to measure forces and torque on the magnet for different CI models and assess the effectiveness of the design and preventative measures on the probability of magnet dislocation.

Six CI models from four manufacturers covering all the current CI brands were included. Each model was positioned on a polystyrene head with compression bandage and magnet cover according to the recommendations of the manufacturer and tested for dislocation in a 1.5T whole-body MRI system. In addition, measurements of the displacement force in front of the MRI scanner and torque at the MRI scanner isocenter were obtained.

Chance of CI magnet dislocation was observed for two CI models.
