[Oncology Reports 29 109‑116, 2013; DOI 10.3892/or.2012.2069].The aim of the present study was to construct and characterize human epidermal growth factor receptor 2 (HER2) lipid magnetic ball (H‑LMB) for separating circulating tumor cells (CTCs) in patients with gastric carcinoma (GC) and to compare the result of separated CTC counts with that of next‑generation sequencing (NGS) for single‑gene analysis to verify the consistency for evaluating the association between the detection results and the progress of clinical treatment, so as to facilitate early diagnosis and dynamic monitoring of GC. A lipid magnetic ball (LMB), coated with Fe3O4 nanoparticles, was synthesized by microemulsion technique and an anti‑HER2 antibody was conjugated to the surface of LMB to form H‑LMB, followed by the characterization of the prepared H‑LMB. The detection of capture efficiency of LMBs in GC cells was tested by MTT and expression of HER2 mRNA was determined by reverse transcription‑quantitative PCR. The positive detection rate of HER2 was verified by HER2‑fluorescence in situ hybridization (FISH) test on the separated CTCs from GC. Further verification was performed based on the consistency between the result of separated CTCs and that of single‑gene NGS assay of HER2, associated with the determination of clinical consistency. The constructed H‑LMB exhibited good stability and specificity. The mutation rate of HER2 by the FISH test was 14% in the blood samples of 50 patients with GC and was 14% by NGS assay. The mutation rate of HER2 was 12% in H‑LMB and the positive detection rate was 85.7% compared with the results of the FISH test, indicating consistency with the clinical diagnosis and pathological examination results. In conclusion, the anti‑HER2 antibody‑modified LMB can separate CTCs with HER2 abnormal expression, which exhibits an application potential in GC diagnosis and treatment and is of great clinical significance for the diagnosis and evaluation of its therapeutic effect on GC.C1q/TNF‑α‑related protein 9 (CTRP9) is downregulated in gestational diabetes mellitus (GDM) and may exert a protective effect against GDM, although its mechanism of action is yet to be elucidated. To investigate the specific role of CTRP9 in GDM, the human placental trophoblast cell line HTR8/SVneo was treated with high glucose (HG) to simulate the environment of GDM in vitro. The effects of CTRP9 on the HTR8/SVneo cells and endoplasmic reticulum (ER) stress were analyzed before and after CTRP9 overexpression using reverse transcription‑quantitative PCR and western blotting. The results obtained demonstrated that CTRP9 alleviated ER stress in the trophoblast cell line. After treating with the ER‑stress inducer tunicamycin, cell viability was investigated by performing Cell Counting Kit‑8, TUNEL and western blotting assays, which revealed that CTRP9 increased the activity of HTR8/SVneo cells induced by HG through the alleviation of ER stress. Subsequently, ELISA and western blotting assay results demonstrated that CTRP9 inhibited HG‑induced inflammation of the HTR8/SVneo cells by the reduction in ER stress. Finally, the detection of reactive oxygen species, nitric oxide (NO) synthase and NO levels confirmed that CTRP9 inhibited the oxidative stress of HTR8/SVneo cells induced by HG through the reduction of ER stress. Collectively, the results of the present study suggested that CTRP9 may decrease trophoblast cell damage caused by HG through the suppression of ER stress, and therefore, CTRP9 may potentially be a therapeutic target in the treatment of GDM.Flies are often observed to approach dark objects. To a naive observer they seem to pay selective attention to one out of several objects although previous research identified as a possible underlying mechanism a reflex-like fixation behavior integrating responses to all objects. In a combination of behavioral experiments and computational modelling, we investigated the choice behavior of flies freely walking towards an arrangement of two objects placed at a variable distance from each other. The walking trajectories were oriented towards one of the objects much earlier than predicted by a simple reactive model. We show that object choice can be explained by a continuous control scheme in combination with a mechanism randomly responding to the position of each object according to a stochastic process. This may be viewed as a special form of an implicit attention-like mechanism, for which the model does not require an explicit decision mechanism or a memory for the drawn decision.Over the last decade, there has been a growing interest to understand the link between metabolism and the immune response in the context of metabolic diseases but also beyond, giving then birth to a new field of research. Termed 'immunometabolism', this interdisciplinary field explores paradigms of both immunology and metabolism to provided unique insights into different disease pathogenic processes, and the identification of new potential therapeutic targets. Similar to other inflammatory conditions, the atherosclerotic inflammatory process in the artery has been associated with a local dysregulated metabolic response. Thus, recent studies show that metabolites are more than just fuels in their metabolic pathways, and they can act as modulators of vascular inflammation and atherosclerosis. In this review article, we describe the most common immunometabolic pathways characterised in innate and adaptive immune cells, and discuss how macrophages' and T cells' metabolism may influence phenotypic changes in the plaque. Moreover, we discuss the potential of targeting immunometabolism to prevent and treat cardiovascular diseases (CVDs).The SARS-CoV-2 virus that results in COVID-19 has been found to damage multiple organs beyond the lung. Interestingly, the SARS-CoV-2 spike (S) protein can be found circulating in the blood of COVID-19 patients. Experimental findings are demonstrating that the circulating S protein can bind to receptors resulting in inflammation and cell, tissue, and organ damage. Avolio et al. previously determined that the S protein acting through the cluster of differentiation 147 (CD147) receptor, and another unknown mechanism had detrimental effects on human cardiac pericytes (Clin Sci (Lond) (2021) 135 (24) 2667-2689. DOI 10.1042/CS20210735). These findings support the notion that circulating SARS-CoV-2 S protein could contribute to cardiovascular disease independent of viral infection. Future studies are needed to determine the effect of the S protein on pericytes in other organs and evaluate the effectiveness of CD147 receptor-blocking therapies to decrease organ damage caused by the S protein.
Morbidity of chronic kidney disease (CKD) is increased, with many complications and high mortality rates. The characteristics of oral microbiome in CKD patients have not been reported. This study aims to analyze the oral microbiome, and to demonstrate the potential of microbiome as noninvasive biomarkers for CKD patients.

The study collected 253 oral samples from different regions of China (Central China and East China) prospectively and finally 235 samples completed Miseq sequencing, including 103 samples from CKD patients and 132 healthy controls (HCs).

Compared with HCs (n=88), the oral microbial diversity in CKD patients (n=44) was increased. Fourteen genera including Streptococcus, Actinomyces and Leptotrichia were enriched, while six genera including Prevotella and Haemophilus were decreased in CKD patients. Moreover, 49 predicted microbial gene functions including arginine metabolism and tryptophan metabolism increased, while 55 functions including Ribosome and DNA repair recombination proteins decreased. Furthermore, correlation analysis demonstrated that 38 operational taxonomic units (OTUs) were closely related to 5 clinical indicators of CKD. Notably, 7 optimal biomarkers were identified using random forest model, and the classifier model respectively reached an area under the curve (AUC) of 0.9917 and 0.8026 in the discovery and validation phase, achieving a cross-region validation.

We first illustrated the characteristics of the oral microbiome of patients with CKD, identified the potential of oral microbial makers as noninvasive tools for the diagnosis of CKD and achieved cross-region validation.

This nuclear receptor is likely a tumor suppressor in several cancers but its molecular mechanism of suppression is still under study. Several studies reported that FXR agonism increase the survival of colorectal, biliary tract and liver cancer patients. In addition, FXR expression was shown to be downregulated in many diseases such as obesity, irritable bowel syndrome, glomerular inflammation, diabetes, proteinuria and ulcerative colitis. Therefore, development of novel FXR agonists may have significant potential in the prevention and treatment of these diseases. In this scenario, computer-aided drug design procedures can be resourcefully applied for the rapid identification of promising drug candidates. In the present research study, we applied the molecular docking method in conjunction with molecular dynamics (MD) simulations to find out potential agonists for FXR based on structural similarity with the drug that is currently used as FXR agonist, obeticholic acid. Our results showed that alvimopan and montelukast could be used as potent FXR activators and outperform the binding affinity of obeticholic acid by forming stable conformation with the protein in silico. However, further investigational studies and validations of the selected drugs are essential to figure out their suitability for in vivo experiments and clinical trials.Amphiphilic nanogels (NGs) combine a soft, water-swollen hydrogel matrix with internal hydrophobic domains. While these domains can encapsulate hydrophobic cargoes, the amphiphilic particle surface can reduce colloidal stability and/or limit biological half-life. Therefore, a functional hydrophilic shell is needed to shield the amphiphilic network and tune interactions with biological systems. AG825 To adjust core and shell properties independently, we developed a synthetic strategy that uses preformed dual-reactive nanogels. In a first step, emulsion copolymerization of pentafluorophenyl methacrylate (PFPMA) and a reduction-cleavable crosslinker produced precursor particles for subsequent network modification. Orthogonal shell reactivity was installed by using an amphiphilic block copolymer (BCP) surfactant during this particle preparation step. Here, the hydrophilic block poly(polyethylene glycol methyl ether methacrylate) (PPEGMA) contains a reactive alkyne end group for successive functionalization. The hydrophobic block (P(PFPMA-co-MAPMA) contains random methacryl-amido propyl methacrylamide (MAPMA) units to covalently attach the surfactant to the growing PPFPMA network. In the second step, orthogonal modification of the core and shell was demonstrated. Network functionalization with combinations of hydrophilic (acidic, neutral, or basic) and hydrophobic (cholesterol) groups gave a library of pH- and redox-sensitive amphiphilic NGs. Stimuli-responsive properties were demonstrated by pH-dependent swelling and reduction-induced degradation via dynamic light scattering. Subsequently, copper-catalyzed azide-alkyne cycloaddition was used to attach azide-modified rhodamine as model compound to the shell (followed by UV-Vis). Overall, this strategy provides a versatile platform to develop multi-functional amphiphilic nanogels as carriers for hydrophobic cargoes.
