: Posterior capsule opacification (PCO) commonly develops following cataract surgery and is a wound-healing response that can ultimately lead to secondary visual loss. Improved management of this problem is required. The isothiocyanate, sulforaphane (SFN), is reported to exert cytoprotective and cytotoxic actions, and the latter may be exploited to treat/prevent PCO. SFN concentrations of 10 μM and above significantly impaired wound-healing in a human lens capsular bag model. A similar pattern of response was also seen with a human lens cell line, FHL124...

: Joint homeostasis failure can result in osteoarthritis (OA). Currently, there are no treatments to alter disease progression in OA, but targeting early changes in cellular behavior has great potential. Recent data show that nuclear receptors contribute to the pathogenesis of OA and could be viable therapeutic targets, but their molecular mechanisms in cartilage are incompletely understood. This study examines global changes in gene expression after treatment with agonists for four nuclear receptor implicated in OA (LXR, PPARδ, PPARγ, and RXR)...

: Renal mesangial cells are regarded as main players in glomerular inflammatory diseases. To investigate a possible crosstalk between inflammatory and hypoxia-driven signaling processes, we stimulated cultured mouse mesangial cells with different inflammatory agents and analyzed the expression of prolyl hydroxylase domain containing proteins (PHDs), the main regulators of hypoxia-inducible factor (HIF) stability. Administration of IL-1β (1 nM) and TNF-α (1 nM), a combination further referred to as cytokine mix (CM), resulted in a fivefold increase in PHD3 but not PHD1 and PHD2 mRNA expression compared to untreated controls...

Epithelial-to-Mesenchymal Transition (EMT) is a complex process that supports the migratory capacity of epithelial tumor cells and is thought to play a crucial role in promoting cancer metastasis. Despite the wealth of experimental data, the exact role of EMT in cancer patients remains more controversial. Over the past 10 years, sensitive technologies that allow the detection and molecular characterization of circulating tumor cells (CTCs) in the peripheral blood of tumor patients have been developed. These analyses help to shed new light into the importance of EMT for human tumor cell dissemination...

: Acriflavine, a fluorescent drug previously used for bacterial and trypanosomal infections, reduces hypoxia-inducible factor-1 (HIF-1) and HIF-2 transcriptional activity. In mice with oxygen-induced ischemic retinopathy, intraocular or intraperitoneal injections of acriflavine caused dose-dependent suppression of retinal neovascularization (NV) and significantly reduced expression of HIF-1-responsive genes. Intraocular injection of 100 ng caused inner retina fluorescence within 1 h that was seen throughout the entire retina between 1 and 5 days, and at 7 days after injection, strongly suppressed choroidal NV at Bruch's membrane rupture sites...

: Restenosis after angioplasty is a serious clinical problem that can result in re-occlusion of the coronary artery. Although current drug-eluting stents have proved to be more effective in reducing restenosis, they have drawbacks of inhibiting reendothelialization to promote thrombosis. New treatment options are in urgent need. We have shown that netrin-1, an axon-guiding protein, promotes angiogenesis and cardioprotection via production of nitric oxide (NO). The present study examined whether and how netrin-1 attenuates neointimal formation in a femoral wire injury model...

It is nowadays generally accepted that the microbiome is a central driver of chronic inflammatory bowel diseases based on observations from human patients as well as inflammatory rodent models. Many studies focussed on different aspects of microbiota and some scientists believe that a primary dis-balance results in a direct microbial induced inflammatory situation. It is also clear that the microbiome is influenced by environmental and genetic factors and is also tightly regulated by host defense molecules such as antimicrobial peptides (defensins et al...

The chemotherapeutic agent doxorubicin (DOX) has significantly increased survival rates of pediatric and adult cancer patients. However, 10% of pediatric cancer survivors will 10-20 years later develop severe dilated cardiomyopathy (DCM), whereby the exact molecular mechanisms of disease progression after this long latency time remain puzzling. We here revisit the hypothesis that elevated apoptosis signaling or its increased likelihood after DOX exposure can lead to an impairment of cardiac function and cause a cardiac dilation...

: Ankylosing spondylitis (AS) is a chronic inflammatory disease characterized by pathological osteogenesis and inflammation. However, the pathogenesis of AS and the pathological relationship between osteogenesis and inflammation in this disease remain largely unknown. Mesenchymal stem cells (MSCs) are multipotent progenitor cells capable of osteogenic differentiation and immunoregulation. Recently, we demonstrated that MSCs from AS patients (ASMSCs) have a greater potential for osteogenic differentiation than MSCs from healthy donors (HDMSCs), which therefore seems to be a component of pathological osteogenesis in AS...

: Non-steroidal anti-inflammatory drug (NSAID)-associated endoplasmic reticulum (ER) stress (a cyclooxygenase-2-independent mechanism) and consequent autophagic cell death are responsible for NSAID-associated gastric damage. Therefore, alleviating cytotoxicity executed via ER stress and autophagy can be a strategy to prevent NSAID-associated gastric damage. Here, we explored whether genetic or pharmacologic inhibition of autophagy can mitigate NSAID-associated gastric damage in in vitro and in vivo models...

: The aryl hydrocarbon receptor (AhR)-ligand axis is involved in immune regulation, but its molecular basis remains to be fully elucidated. Chemokine (C-C motif) ligand 1 (CCL1) is an important chemoattractant, but how CCL1 is regulated remains to be defined. The role of AhR in regulating CCL1 expression in two major subsets of macrophage was investigated. We used a human THP-1 cell line, monocytes, and mouse peritoneal macrophages to generate M(IFN-γ/LPS) and M(IL-4) subsets, and the AhR's ligand effect was determined by the use of a combination of chromatin immunoprecipitation, PCR, and ELISA...

: BPC 157, a pentadecapeptide with extensive healing effects, has recently been suggested to contribute to angiogenesis. However, the underlying mechanism is not yet clear. The present study aimed to explore the potential therapeutic effect and pro-angiogenic mechanism of BPC 157. As demonstrated by the chick chorioallantoic membrane (CAM) assay and endothelial tube formation assay, BPC 157 could increase the vessel density both in vivo and in vitro, respectively. BPC 157 could also accelerate the recovery of blood flow in the ischemic muscle of the rat hind limb as detected by laser Doppler scanning, indicating the promotion of angiogenesis...

Diabetes mellitus is one of the most common chronic diseases that threatens human health in worldwide populations. Despite enormous efforts invested in the study of diabetes mellitus, the development of precise diagnoses and treatments for this disease remains difficult due to the limitations of current techniques. Therefore, new methods are currently being developed. Aptamers are oligonucleotides that bind to specific target molecules and have been widely applied as diagnostic and therapeutic tools. In recent years, aptamers have been utilized in the study of diabetes mellitus and metabolic diseases...

: Searching for potential anticancer agents from natural sources is an effective strategy for developing novel chemotherapeutic agents. In this study, data supporting the in vitro and in vivo anticancer effects of delicaflavone, a rarely occurring biflavonoid from Selaginella doederleinii, were reported. Delicaflavone exhibited favorable anticancer properties, as shown by the MTT assay and xenograft model of human non-small cell lung cancer in male BALB/c nude mice without observable adverse effect...

: Mutations affecting splicing underlie the development of many human genetic diseases, but rather rarely through mechanisms of pseudoexon activation. Here, we describe a novel c.1092T>A mutation in the iduronate-2-sulfatase (IDS) gene detected in a patient with significantly decreased IDS activity and a clinical diagnosis of mild mucopolysaccharidosis II form. The mutation created an exonic de novo acceptor splice site and resulted in a complex splicing pattern with multiple pseudoexon activation in the patient's fibroblasts...

The increasing threat of antimicrobial resistance poses one of the greatest challenges to modern medicine. The collection of all antimicrobial resistance genes carried by various microorganisms in the human body is called the human resistome and represents the source of resistance in pathogens that can eventually cause life-threatening and untreatable infections. A deep understanding of the human resistome and its multilateral interaction with various environments is necessary for developing proper measures that can efficiently reduce the spread of resistance...

Bacterial species composition in the gut has emerged as an important factor in obesity and its related metabolic diseases such as type 2 diabetes. Out of thousands of bacterial species-level phylotypes inhabiting the human gut, the majority belong to two dominant phyla, the Bacteroidetes and Firmicutes. Members of the Bacteroidetes in particular have been associated with human metabolic diseases. However, their associations with disease are not always consistent between studies. Delving deeper into the diversity within the Bacteroidetes reveals a vast diversity in genomes and capacities, which partly explain how not all members respond equally to similar environmental conditions in their hosts...

The microbiome located within a given host and its organs forms a holobiont, an intimate functional entity with evolutionarily designed interactions to support nutritional intake and reproduction. Thus, all organs in a holobiont respond to changes within the microbiome. The development and function of the central nervous system and its homeostatic mechanisms are no exception and are also subject to regulation by the gut microbiome. In order for the holobiont to function effectively, the microbiome and host must communicate...
