In addition to stability, the findings revealed that not only the ice nucleation temperature, but also the thermal history of the formulation post ice nucleation defines the surface area of ice and the porous structure of the freeze-dried cake. Dietary supplement companies have recently started to focus on the personalization of products and the improvement of the relevant performance. In this respect, a versatile, easy-to-handle capsular delivery platform with customizable content and release kinetics was here proposed and evaluated after filling with caffeine as a model dietary ingredient. In particular, capsular devices comprising 1 to 3 independent inner compartments were attained by Lego-inspired assembly of matching modular units with different wall compositions, manufactured by injection molding and fused deposition modeling 3D printing. Accordingly, one-, two- and three-pulse release profiles of the dietary ingredient were obtained from differently assembled devices following the breakup of the compartments occurring promptly (immediate-release), on pH change (delayed-release) or after tunable lag times (pulsatile-release). The latter release mode would enable the onset of the stimulating effect of caffeine at different times of the day after a single administration when convenient. The performance of each individual compartment only depended on the composition (i.e., promptly soluble, swellable/soluble or enteric soluble polymers) and thickness of its own wall, while it was not affected by the composition and number of joined modular units. Moreover, the delivery platform was extended to include an external gastroresistant shell enclosing previously assembled devices. AIMS Obesity is associated with adipose tissue (AT) dysfunction marked by cellular hypertrophy, inflammation, hypoxia and fibrosis. Angiopoietin-like protein 4 (ANGPTL4) inhibits lipoprotein lipase which regulates triglyceride storage. Recently, inhibition of ANGPTL4 has been suggested as potential treatment for type 2 diabetes. Here we evaluate ANGPTL4's role in diabetes and examine ANGPTL4 in relation to markers of AT dysfunction and fatty liver disease. MATERIALS & METHODS We obtained a unique set of paired samples from subjects undergoing weight loss surgery including subcutaneous AT (SCAT), omental AT (OMAT), liver, thigh muscle biopsies and serum including a post-surgical SCAT biopsy after 9 months. RESULTS SCAT ANGPTL4 expression and circulating protein levels were higher in people with diabetes and correlated with glucose levels and HOMA-IR but not BMI. At post-surgical follow up, SCAT ANGPTL4 declined in subjects with diabetes to levels of those without diabetes. ANGPTL4 expression correlated with HIF1A and inflammation (MCP-1, IL-6). CONCLUSIONS We found that SCAT ANGPTL4 was closely linked with the expression of ANGPTL4 in the liver and represented a good proxy for liver steatosis. We suggest the elevation of ANGPTL4 levels in diabetes and the association with inflammation and hypoxia is due to a compensatory mechanism to limit further AT dysfunction. A reduction of ANGPTL4 for the treatment of T2DM as previously suggested is thus unlikely to be of further benefit. BACKGROUND Low-density lipoprotein receptor-related protein 1 (LRP1) plays a key role in fatty acid metabolism and glucose homeostasis. In the context of dyslipemia, LRP1 is upregulated in the heart. Our aim was to evaluate the impact of cardiomyocyte LRP1 deficiency on high fat diet (HFD)-induced cardiac and metabolic alterations, and to explore the potential mechanisms involved. METHODS We used TnT-iCre transgenic mice with thoroughly tested suitability to delete genes exclusively in cardiomyocytes to generate an experimental mouse model with conditional Lrp1 deficiency in cardiomyocytes (TNT-iCre+-LRP1flox/flox). FINDINGS Mice with Lrp1-deficient cardiomyocytes (cm-Lrp1-/-) have a normal cardiac function combined with a favorable metabolic phenotype against HFD-induced glucose intolerance and obesity. Glucose intolerance protection was linked to higher hepatic fatty acid oxidation (FAO), lower liver steatosis and increased whole-body energy expenditure. Proteomic studies of the heart revealed decreased levels of cardiac pro-atrial natriuretic peptide (pro-ANP), which was parallel to higher ANP circulating levels. cm-Lrp1-/- mice showed ANP signaling activation that was linked to increased fatty acid (FA) uptake and increased AMPK/ ACC phosphorylation in the liver. Natriuretic peptide receptor A (NPR-A) antagonist completely abolished ANP signaling and metabolic protection in cm-Lrp1-/- mice. CONCLUSIONS These results indicate that an ANP-dependent axis controlled by cardiac LRP1 levels modulates AMPK activity in the liver, energy homeostasis and whole-body metabolism. Siglec-15 is an immunoreceptor that binds to its ligand to exert diverse functions in osteoclast development, bone resorption, and even tumor-associated macrophage-mediated T cell immunity. Siglec-15 is a highly conserved member of the Siglec family and is constitutively expressed in osteoclasts, macrophages and dendritic cells. The activation domain in Siglec-15 can transmit a positive signal to regulate osteoclastogenesis via the formation of a complex with DAP12. check details In tumors, Siglec-15 is negatively regulated by IFN-γ, thus influencing effector T cell-mediated antitumor immunity. Importantly, this tumor-associated function of Siglec-15 is similar to that identified for PD-L1/PD-1 in normalization cancer immunotherapy. Cell-directed therapies are increasingly urgent and of clinical interest for their potential for reduced side effects and increased safety. Therefore, targeting Siglec‑15 might lead to novel discoveries for the clinical treatment of bone and tumor diseases or related diseases. BACKGROUND Studies have demonstrated that the failure of oligodendrocyte precursor cells (OPCs) differentiation as a major cause of remyelination failure in demyelinating disease. The reasons for this failure are not completely understood. We hypothesized that the present of myelin debris in CNS play an important role in poor OPCs differentiation in the mouse model of demyelinating disease. METHODS Mice were fed by the food mixed with normal or 0.2 % cuprizone (CPZ) for 6 weeks. Then the learning and memory impairment were tested by Morris water maze test. The spontaneous alternation behavior and depression-like symptoms were assessed by tail suspension test and open filed test. The number of OPCs and oligodendrocytes were counted by immunofluorescence. After exposed to CPZ for 6 weeks, the mice were then receiving stereotactic injection of NEP1-40 into the CA3 of hippocampus. The behavioral, learning and memory changes were assessed by tail suspension test and open field test. The differentiation of OPCs were detected by immunofluorescence and western blot. RESULTS The mice in CPZ group are more likely to show signs of depression and they showed impairment of long-term learning and memory function. The differentiation of OPCs were impaired in CPZ group. We found that mice treated with NEP1-40 showed less depression-like symptom in TST and higher locomotor activity in the OFT than the mice treated with PBS. CONCLUSIONS Our study suggest that NEP1-40 can promote OPC differentiation and survival. Further study should focus on the effect of NEP1-40 on the differentiation and survival of OPCs in vitro. Blood levels of progranulin (PGRN) are suggested to be decreased in patients with Parkinson's disease (PD). However, the association between blood levels of progranulin and the severity of PD is not yet clear. A total of 55 PD patients and 55 normal control (NC) subjects were recruited in the present study. Hoehn and Yahr stages (H&Y) and Unified Parkinson's Disease Rating Scale scores (UPDRS) were examined to assess the severity of the disease. UPDRS motor section (UPDRS-III) was used to assess the motor function of the patients. Plasma levels of PGRN were tested by Elisa assays. Plasma PGRN levels are significantly decreased in PD patients (PD vs. NC 333.8 ± 8.067 vs. 364.2 ± 10.11 ng/ml, p = 0.020). In the subgroup analysis, plasma PGRN levels decrease as H&Y score increases (H&Y = 1 vs. H&Y = 2 363.5 ± 3.251 vs. 336.3 ± 7.403 ng/ml, p = 0.013; H&Y = 1 vs. H&Y = 3-5 363.5 ± 3.251 vs. 218.1 ± 18.12 ng/ml, p  less then  0.001; H&Y = 2 vs. H&Y = 3-5 336.3 ± 7.403 vs. 218.1 ± 18.12 ng/ml, p = 0.076). Plasma levels of progranulin are negatively correlated with the severity of PD, as reflected by UPDRS (γ=-0.754, p  less then  0.001), UPDRS-III (γ=-0.808, p  less then  0.001) and disease duration (γ=-0.633, p  less then  0.001). Circulating PGRN levels might be a potential indicator of the disease severity of PD. Glioma is the most common primary malignant tumor in the human brain. Although there are a variety of treatments, such as surgery, radiation and chemotherapy, glioma is still an incurable disease. Super-enhancers (SEs) are implicated in the control of tumor cell identity, and they promote oncogenic transcription, which supports tumor cells. Inhibition of the SE complex, which is required for the assembly and maintenance of SEs, may repress oncogenic transcription and impede tumor growth. In this review, we discuss the unique characteristics of SEs compared to typical enhancers, and we summarize the recent advances in the understanding of their properties and biological role in gene regulation. Additionally, we highlight that SE-driven lncRNAs, miRNAs and genes are involved in the malignant phenotype of glioma. Most importantly, the application of SE inhibitors in different cancer subtypes has introduced new directions in glioma treatment. BACKGROUND Circular RNAs (circRNAs) are a special type of non-coding RNA. To elucidate the relationship between hemodynamics and the function of circRNAs in endothelial cells (ECs), a modified T chamber system was designed and produced for the present experiment. This T chamber system can be used to simulate the hemodynamic environment at the bifurcation of the arteries. METHODS Normal ECs cultured on glass slides were placed in the T chamber, the cell layer was impacted at a flow rate of 500 mL/min, and high-throughput microarrays were used to analyze the expression profiles of circRNAs in ECs. The differential expressions of circRNAs in the ECs treated with impinging flow were compared to those in ECs in conventional culture conditions. The characteristics of the differentially expressed circRNAs were analyzed with bioinformatics and quantitative reverse transcription polymerase chain reaction analyses were conducted to verify results. RESULTS Compared to normal samples, there were changes in the expressions of many circRNAs. A total of 974 circRNAs were differentially expressed, and of these, 378 were upregulated and 596 were downregulated (fold change [FC] ≥ 2 and P less then 0.05), which suggests that these circRNAs were altered under hemodynamic conditions. CONCLUSIONS We present the differential expression profiles of circRNAs in ECs after the application of impinging flow; our results indicate that these differentially expressed circRNAs may be involved in inflammatory responses and damage in ECs. The present findings provide valuable information on cRNA profiles as well as clues for future studies that will investigate the roles that circRNAs play in ECs after inflammatory injury.
