In rodent models of insulin-deficient diabetes, 17β-estradiol (E2) protects pancreatic insulin-producing β-cells against oxidative stress, amyloid polypeptide toxicity, gluco-lipotoxicity, and apoptosis. Three estrogen receptors (ERs)-ERα, ERβ, and the G protein-coupled ER (GPER)-have been identified in rodent and human β-cells. This chapter describes recent advances in our understanding of the role of ERs in islet β-cell function, nutrient homeostasis, survival from pro-apoptotic stimuli, and proliferation...

Homeobox A5(Hoxa5), a member of the Hox family, plays a important role in the regulation of proliferation and apoptosis in cancer cells. The dysregulation of the adipocyte apoptosis in vivo leads to obesity and metabolic disorders. However, the effects of Hoxa5 on adipocyte apoptosis are still unknown. In this study, palmitic acid (PA) significantly increased the mRNA level of Hoxa5 and triggered white adipocyte apoptosis in vivo and in vitro. Further analysis revealed that Hoxa5 enhanced the early and late apoptotic cells and fragmentation of genomic DNA in adipocytes from inguinal white adipose tissue (iWAT) of mice...

The Warburg effect describes how most cancer cells exhibit higher-than-normal glucose consumption, not only under hypoxic conditions, but also when normal oxygen levels are present. Although glucose transporter 1 (GLUT1) has been found to play a key role in the cellular uptake of glucose, especially in cancer cells, where it is generally overexpressed, it has not been given consideration as a suitable target for the development of anticancer drugs. In this chapter, an example of molecular design and realization of novel GLUT1 inhibitors, including in silico modeling, chemical synthesis, and biological characterization, is provided...

AIMS: Vascular calcification (VC) underlies substantial cardiovascular morbidity and mortality. No clinically therapies have emerged presently. Stellate ganglion block (SGB) is one of the most often used sympathetic blockade procedure, and regulates vascular dilation. However, the effect of SGB on VC is still unknown. Therefore, we aimed to identify the ameliorative effect of SGB on VC. KEY FINDING: In vivo VC was induced in rats by administering vitamin D3 plus nicotine (VDN), and in vitro calcification of rat aortic vascular smooth muscle cells (VSMC) was induced by β-glycerophosphate...

Palmitate (PA) has been identified to induce cell apoptosis in osteoblasts. The c‑Jun NH2‑teminal kinase (JNK) signaling pathway and endoplasmic reticulum stress (ERS) were found to be important contributors. Therefore, natural or synthetic agents may antagonize PA‑induced apoptosis in osteoblasts, and demonstrate the potential application to reverse osteoporosis. The present study demonstrated that the Lycium barbarum polysaccharide (LBP) is as a major active ingredient of Lycium barbarum and that it can reduce the fatty acid toxicity of PA...

The present study aimed to investigate the role of periostin (POSTN) and high melatonin concentrations in the apoptosis of hFOB 1.19 human normal fetal osteoblastic cells. hFOB 1.19 human osteoblastic cells were stably cultured and treated in different concentrations of melatonin for different durations of action. Apoptosis was assessed quantitatively using flow cytometric analysis. The results of western blot analysis demonstrated that the treatment of cells with different concentrations of melatonin for different durations of action revealed a positive association between melatonin and the expression levels of glucose‑regulated protein (GRP)78, GRP94, phosphorylated (p‑) eukaryotic initiation factor 2α (eIF2α), activating transcription factor (ATF)4, CCAAT/enhanced binding protein homologous protein (CHOP), cleaved caspase‑3, p‑c‑Jun N‑terminal kinase (JNK) and POSTN...

INTRODUCTION: Prostate carcinoma (PRAD) is one of the most frequently diagnosed malignancies amongst men worldwide. It is well-known that androgen receptor (AR) plays a pivotal role in a vast majority of prostate tumors. However, recent evidence emerged stating that estrogen receptors (ERs) may also contribute to prostate tumor development. Moreover, progression and aggressiveness of prostate cancer may be associated with differential expression genes of epithelial-to-mesenchymal transition (EMT)...

Intestinal absorption and barrier malfunctions are associated with endoplasmic reticulum stress (ERS) in the intestine. We induced ERS by exposing the intestinal porcine epithelial cell line J2 (IPEC-J2) to tunicamycin (TUNI) to explore the potential of l-glutamine to reduce ERS-induced apoptosis. Our experiments demonstrated that exposing cells to TUNI results in spontaneous ERS and encourages the upregulation of glucose-regulated protein 78 (GRP78). Prolonged TUNI-induced ERS was found to increase apoptosis mediated by C/enhancer binding protein homologous protein (CHOP), accompanied by GRP78 downregulation...

Early repolarization syndrome (ERS) was originally considered a normal variant with benign outcome. However, recent studies have demonstrated that it can be linked to a considerable risk of life-threatening arrhythmias and sudden cardiac death. We report a case with an extraordinary, extremely malignant clinical expression of ERS refractory to all antiarrhythmic drugs including quinidine. This case demonstrates real-time changes of dynamic electrocardiogram (ECG) preceding a polymorphic ventricular tachycardia (VT)-ventricular fibrillation (VF) and possible external factors triggering arrhythmia onset...

INTRODUCTION: Compression ultrasound is a non-invasive technique allowing for qualitative visualization and quantitative measurements of mechanical tissue properties. In acute compartment syndrome (ACS), cadaver studies have proven that the intra-compartmental pressure (ICP) measured by compression sonography correlates with the ICP measured invasively. This study aimed to evaluate compression sonography for compartment pressure measurements in an animal model. MATERIAL AND METHODS: The pressure in the anterior tibial compartment of 6 domestic pig legs was increased from baseline to 40mmHg in 5mmHg steps...

BACKGROUND: In several countries, attempts are made to improve health promotion by centrally rating the effectiveness of health promotion interventions. The Dutch Effectiveness Rating System (ERS) for health promotion interventions is an improvement-oriented approach in which multi-disciplinary expert committees rate available health promotion interventions as 'theoretically sound', 'probably effective' or 'proven effective'. The aim of this study is to explore the functioning of the ERS and the perspective of researchers, policy-makers and practitioners regarding its contribution to improvement...

BACKGROUND/AIMS: Growing evidence suggests mitochondrial dysfunction (MtD) and the Nlrp3 inflammasome play critical roles in chronic kidney disease (CKD) progression. We previously reported that Aldosterone (Aldo)-induced renal injury in vitro is directly caused by mitochondrial reactive oxygen species (mtROS)-mediated activation of the Nlrp3 inflammasome. Here we aimed to determine whether a mitochondria-targeted antioxidant (Mito-Tempo) could prevent Aldo-induced kidney damage in vivo...
