Osteosarcoma is the most common primary bone tumor characterized by high risk of metastasis, thus presents with an overall survival rate of 60%, despite the use of chemotherapy and surgery. Metastasis‑associated lung adenocarcinoma transcript 1 (MALAT‑1) has been reported to upregulated and epigenetically regulate the metastasis in osteosarcoma; however, the regulatory mechanisms of MALAT‑1 expression remain unclear. In the current study, significant upregulation of MALAT‑1 was observed subsequent to exposure to low concentrations of 17β‑estradiol (E2) in U2OS cells...

In this study, we investigated the association between the renin-angiotensin system (RAS), endoplasmic reticulum (ER) stress and atherosclerosis (AS) in uremic apolipoprotein E knockout (apoE-/-) mice. Mild uremia was induced by a 5/6 nephrectomy (5/6 Nx) in 10-week-old apoE-/- mice. Four weeks after nephrectomy, the mice received losartan or no treatment for 16 weeks. Sham-operated mice served as the controls. We found that uremia accelerated AS at the aortic root. The activation of ER stress and the significant upregulation of pro-inflammatory cytokines and chemokines were observed in the uremic mice...

Oxidative stress is considered as an important mediator in the progression of metabolic disorders. The objective of this study was to investigate the potential hepatoprotective effects and mechanisms of bovine casein glycomacropeptide hydrolysates (GHP) on hydrogen peroxide (H₂O₂)-induced oxidative damage in HepG2 cells. Results showed that GHP significantly blocked H₂O₂-induced intracellular reactive oxygen species (ROS) generation and cell viability reduction in a dose-dependent manner. Further, GHP concentration-dependently induced heme oxygenase-1 (HO-1) expression and increased nuclear factor-erythroid 2-related factor 2 (Nrf2) nuclear translocation...

The inflammatory milieu plays an important role in colon cancer development and progression. Previously, we have shown that tumor-associated macrophages (TAMs), an important component of the tumor microenvironment, are enriched in tumors compared with normal tissue and confer a poorer prognosis. In the present study, we found that matrix metallopeptidase-9 (MMP-9), which degrades extracellular matrix proteins, was increased in biopsies from colon cancer patients and in mouse xenografts with SW480 cell-derived tumors...

Nursery grown plants of Nerium oleander, Pogonatherum crinitum, and Portulaca oleracea were observed to remove fluoride up to 92, 80, and 73%, respectively, from NaF solution at the concentration of 10 mg L(-1) within 15 days. Concentration range of 10-50 mg L(-1) of fluoride revealed a constant decrease of removal from 92 to 51% within 15 days by N. oleander, while the biomass (one to five plants) showed enhancement in removal from 74 to 98% in 10 days. Translocation and bioaccumulation factors calculated after fluoride contents in roots and leaves of N...

Therapy that directly targets apoptosis and/or inflammation could be highly effective for the treatment of cancer. Murraya koenigii is an edible herb that has been traditionally used for cancer treatment as well as inflammation. Here, we describe that girinimbine, a carbazole alkaloid isolated from M. koenigii, induced apoptosis and inhibited inflammation in vitro as well as in vivo. Induction of apoptosis in human colon cancer cells (HT-29) by girinimbine revealed decreased cell viability in HT-29, whereas there was no cytotoxic effect on normal colon cells...

The nucleolus, a dynamic nuclear compartment long regarded as the cell ribosome factory, is emerging as an important player in the regulation of cell survival and recovery from stress. In larger eukaryotes, the stress-induced transcriptional response is mediated by a family of heat-shock transcription factors. Among these, HSF1, considered the master regulator of stress-induced transcriptional responses, controls the expression of cytoprotective heat shock proteins (HSPs), molecular chaperones/cochaperones constituting a major component of the cell protein quality control machinery essential to circumvent stress-induced degradation and aggregation of misfolded proteins...

Modulation of N-acylethanolamine-hydrolyzing acid amidase (NAAA) represents a potential alternative strategy in the treatment of neuroinflammation. Recent studies showed that pharmacological modulation of NAAA could be achieved with the oxazoline of palmitoylethanolamide (PEA) (PEA-OXA). The aim of this study was to evaluate the neuroprotective effects of PEA-OXA in the secondary neuro-inflammatory events induced by spinal and brain trauma in mice. Animals were subjected to spinal cord and brain injury models and PEA-OXA (10 mg/kg) administered both intraperitoneally and orally 1 h and 6 h after trauma...

The heliangin is a natural agent mainly isolated from Helianthus tuberosus L. (Asteraceae). In order to investigate the anti-inflammatory effect of heliangin, several typical models in vivo and in vitro were performed. The RAW264.7 mouse macrophages cells were employed in vitro and dexamethasone were conducted as positive. The cytotoxicity results of heliangin on RAW 264.7 cells provided the safety in vitro for further study. The mRNA of TNF-α, IL-6, iNOS and COX-2 were degraded under heliangin exposure in LPS-stimulated RAW 264...

Outer membrane protein F (OmpF) is an abundant trimeric general diffusion porin that plays a central role in the transport of antibiotics and colicins across the outer membrane of E. coli. Individual OmpF trimers in planar lipid bilayers (PLB) show one of two current-voltage asymmetries, implying that insertion occurs with either the periplasmic or the extracellular end first. A method for establishing the orientation of OmpF in PLB was developed based on the targeted covalent modification, with membrane-impermeant reagents, of peripheral cysteine residues introduced near the periplasmic or the extracellular entrance...

Positron emission tomography (PET) imaging with radiotracers that target translocator protein 18 kDa (TSPO) has become a popular approach to assess putative neuroinflammatory processes and associated microglia activation in psychotic illnesses. It remains unclear, however, whether TSPO imaging can accurately capture low-grade inflammatory processes such as those present in schizophrenia and related disorders. Therefore, we evaluated the validity of TSPO as a disease-relevant marker of inflammation using a translational approach, which combined neurodevelopmental and neurodegenerative mouse models with PET imaging in patients with recent-onset schizophrenia and matched controls...

Multiple signaling pathways that promote tumor cell metastasis are differentially activated in low/non-metastatic and metastatic tumor cells, resulting in the differential expression of metastasis-related genes. The underlying mechanism may involve the alterations of the intrinsic negative regulation in tumor cells. Here we report that the differential expression of interleukin-37b (IL-37b) in tumor cells alters the intrinsic negative regulation of signaling pathways, resulting in the difference of metastatic capacity...

NF-κB and STAT3 are essential transcription factors in immunity and act at the interface of the transition from chronic inflammation to cancer. Different functional crosstalks between NF-κB and STAT3 have been recently described arguing for a direct interaction of both proteins. During a systematic analysis of NF-κB/STAT3 crosstalk we observed that appearance of the subcellular distribution of NF-κB and STAT3 in immunofluorescence heavily depends on the fixation procedure. Therefore, we established an optimized fixation protocol for the reliable simultaneous analysis of the subcellular distributions of both transcription factors...

The Golgi assembly pattern varies among cell types. In fibroblast cells, the Golgi apparatus concentrates around the centrosome that radiates microtubules; whereas in epithelial cells, whose microtubules are mainly noncentrosomal, the Golgi apparatus accumulates around the nucleus independently of centrosome. Little is known about the mechanisms behind such cell type-specific Golgi and microtubule organization. Here, we show that the microtubule minus-end binding protein Nezha/CAMSAP3 (calmodulin-regulated spectrin-associated protein 3) plays a role in translocation of Golgi vesicles in epithelial cells...

BACKGROUND: Nuclear factor-erythroid related factor-2 (Nrf2) is a master regulator of transcriptional activation of anti-oxidants in cells. Similarly, heme oxygenase (HO) is a cytoprotective protein with anti-oxidant effects. This review article will shed more light on the interaction between Nrf2 and HO. METHODS AND RESULTS: A PubMed search was done for recent articles on Nrf2 and HO. These studies suggested that under normal physiological conditions, Nrf2 is bound within the cytoplasm to its repressor, Kelch-like ECH-associated protein (Keap1), an oxidative stress sensor...

Spontaneous bacterial peritonitis occurs most commonly in cirrhotic patients with ascites. Pathogens get into the circulation by intestinal translocation and colonize in peritoneal fluid. Diagnosis of spontaneous bacterial peritonitis is based on elevated polymorphonuclear leukocyte count in the ascites (>0,25 G/L). Ascites culture is often negative but aids to get information about antibiotic sensitivity in positive cases. Treatment in stable patient can be intravenous then orally administrated ciprofloxacin or amoxicillin/clavulanic acid, while in severe cases intravenous III...

Nuclear factor κappa B (NF-κB) is an important transcription factor in the development and progression of coronary artery disease (CAD). Recent evidence suggests that -94 ATTG ins/del mutant in the promoter of NFKB1 gene is an essential functional mutant. The present study demonstrated the frequencies of the del/del (DD) genotype and del (D) allele were significantly higher in CAD patients than in controls. CAD patients carrying mutant DD genotype had worse stenosis of diseased coronary arteries compared to those carrying ins/ins (II) or ins/del (ID) genotype...

BACKGROUND: Neuroinflammatory processes including activated microglia have been reported to play an important role in Parkinson's disease (PD). Increased expression of translocator protein (TSPO) has been observed after brain injury and inflammation in neurodegenerative diseases. Positron emission tomography (PET) radioligand targeting TSPO allows for the quantification of neuroinflammation in vivo. METHODS: Based on the genotype of the rs6791 polymorphism in the TSPO gene, we included 25 mixed-affinity binders (MABs) (14 PD patients and 11 age-matched healthy controls (HC)) and 27 high-affinity binders (HABs) (16 PD patients and 11 age-matched HC) to assess regional differences in the second-generation radioligand [(18)F]-FEPPA between PD patients and HC...

A Sleeping Beauty (SB) transposon system is made of a transposon plasmid (containing gene encoding a desired functional or therapeutic protein) and a transposase plasmid (encoding an enzyme capable of cutting and pasting the gene into the host cell genome). It is a kind of natural, nonviral gene delivery vehicle, which can achieve efficient genomic insertion, providing long-term transgenic expression. However, before the SB transposon system could play a role in promoting gene expression, it has to be delivered efficiently first across cell membrane and then into cell nuclei...
