Emerging evidence has indicated that long non-coding RNAs (lncRNAs) play critical roles in tumor development and progression. Recent studies reported that lncRNA MIR22HG could play important roles in hepatocellular carcinoma and lung cancer progression. However, the expression and underlying mechanism of MIR22HG in endometrial cancer (EC) remain unclear. In the present study, qRT-PCR showed that MIR22HG expression was significantly downregulated in EC tissues. In vitro function assays showed that increased MIR22HG expression significantly inhibited EC cells proliferation, induced EC cells apoptosis, and arrested EC cells in G0/G1 phase...

Since comprehensive analysis of the mammalian genome has revealed that the vast majority of genomic products are transcribed in long non-coding RNAs (lncRNAs), increasing attention has been paid towards these transcripts. The applied next-generation sequencing technologies have provided accumulating evidence of dysregulated lncRNAs in cancer. The implication of this finding may be seen in many forms and at multiple levels. With impacts ranging from integrating chromatin remodeling complexes to regulating transcription and post-transcriptional processes, aberrant expression of lncRNAs may have repercussions in cell proliferation, tumor progression or metastasis...

REVIEW

Various stress factors leading to protein damage induce the activation of an evolutionarily conserved cell protective mechanism, the heat shock response (HSR), to maintain protein homeostasis in virtually all eukaryotic cells. Heat shock factor 1 (HSF1) plays a central role in the HSR. HSF1 was initially known as a transcription factor that upregulates genes encoding heat shock proteins (HSPs), also called molecular chaperones, which assist in refolding or degrading injured intracellular proteins. However, recent accumulating evidence indicates multiple additional functions for HSF1 beyond the activation of HSPs...

Diabetic cardiomyopathy refers to a unique set of heart-specific pathological variables induced by hyperglycemia and insulin resistance. Given that cardiovascular disease (CVD) is the leading cause of death in the world, and type 2 diabetes incidence continues to rise, understanding the complex interplay between these two morbidities and developing novel therapeutic strategies is vital. Two hallmark characteristics specific to diabetic cardiomyopathy are diastolic dysfunction and cardiac structural mal-adaptations, arising from cardiac cellular responses to the complex toxicity induced by hyperglycemia with or without hyperinsulinemia...

Protein arginine methyltransferase 5 (PRMT5) regulates gene expression either transcriptionallyly by symmetric dimethylation of arginine residues on histones H4R3, H3R8 and H2AR3, or at the post-translational level by methylation of non-histone target proteins. While emerging evidence suggests that PRMT5 functions as an oncogene, its role in metabolic diseases is not well defined. We investigated the role of PRMT5 in promoting high fat-induced hepatic steatosis. High fat diet up-regulated PRMT5 levels in the liver, but not in other metabolically relevant tissues such as skeletal muscle or white and brown adipose tissue...

Emergency departments play an essential role with regard to social inequalities. However, in the current context, this role is not evident in the studies carried out into this sector of activity. This is due to the lack of relevance of the indicators used, such as the waiting time, which serve the hidden objective of increasing the productivity of emergency departments.

Uncertainty with respect to built environment (BE) data collection, measure conceptualization and spatial scales is evident in urban health research, but most findings are from relatively lowdensity contexts. We selected Hong Kong, an iconic high-density city, as the study area as limited research has been conducted on uncertainty in such areas. We used geocoded home addresses (n=5732) from a large population-based cohort in Hong Kong to extract BE measures for the participants' place of residence based on an internationally recognized BE framework...

Insurance coverage policies are a major determinant of patient access to genomic tests. The objective of this study was to examine differences in coverage policies for guideline-recommended pharmacogenomic tests that inform cancer treatment. We analyzed coverage policies from eight Medicare contractors and 10 private payers for 23 biomarkers (e.g., HER2 and EGFR ) and multi-gene tests. We extracted policy coverage and criteria, prior authorization requirements, and an evidence basis for coverage. We reviewed professional society guidelines and their recommendations for use of pharmacogenomic tests...

Accumulating evidence suggests that metformin, used as an antidiabetic drug, possesses anti-cancer properties. Metformin reduced the incidence and growth of experimental tumors in vivo. In a randomized clinical trial among nondiabetic patients, metformin treatment significantly decreased the number of aberrant crypt foci compared to the untreated group with a follow-up of 1 month. In our study, HT29 cells were treated with graded concentrations of metformin, 10 mM/25 mM/50 mM for 24/48 h. We performed immunofluorescence experiments by means of confocal microscopy and western blot analysis to evaluate a panel of factors involved in apoptotic/autophagic processes and oxidative stress response...

Macrophages are phagocytic immune cells that protect the body from foreign invaders and actively support the immune response by releasing anti- and proinflammatory cytokines. A seminal finding revolutionized the way macrophages are seen. The expression of the neuronal alpha7 nicotinic acetylcholine receptor (α7-nAChR) in macrophages led to the establishment of the cholinergic anti-inflammatory response (CAR) in which the activation of this receptor inactivates macrophage production of proinflammatory cytokines...

microRNAs (miRNAs) are a group of small non-coding RNA molecules known to regulate target genes at the post-transcriptional level. miRNAs are implicated in the regulation of multiple pathophysiological processes including dyslipidemia, a major risk factor for atherosclerosis. Emerging evidence suggests that miRNAs act as a novel class of epigenetic regulators of high-density lipoproteins cholesterol (HDL-C) from synthesis to clearance contributing remarkably to the pathogenesis of atherosclerosis. Accumulating studies have revealed that miRNAs such as miR-33, miR-27, miR-144, miR-758 and miR-20 are involved in the post-transcriptional control of ABCA1, ABCG1 and SCARB1 genes regulatory network of the reverse cholesterol transport (RCT)...

BACKGROUND: One to one specialling is a type of care which is provided to ensure the safety of patients who may be suffering from cognitive impairment, exhibit challenging behaviour, or may be at risk of falls or of causing harm to themselves or others. Care such as this, often referred to as 'specialling' or 'sitting' is common practice in most hospitals around the world, but there is a lack of evidence regarding its cost effectiveness and the quality of care provided. AIM: The aim of this scoping review was to explore the breadth and scope of literature on one to one specialling, sitters and similar types of care in acute secondary care settings, in order to identify the challenges and concerns relating to the quality of care (process and outcomes) and cost effectiveness emerging from the literature, and determine the implications of this for policy, practice and future research...

In rodents, hippocampal cell assemblies formed during learning of a navigation task are observed to re-emerge during resting (offline) periods, accompanied by high-frequency oscillations (HFOs). This phenomenon is believed to reflect mechanisms for strengthening newly-formed memory traces. Using magnetoencephalography recordings and a beamforming source location algorithm (synthetic aperture magnetometry), we investigated high-gamma (80-140 Hz) oscillations in the hippocampal region in 18 human participants during inter-trial rest periods in a virtual navigation task...

According to the Alzheimer Association Report (2017), Alzheimer's disease (AD) is the 6th primary cause of death in the USA, which affects nearly 5.5 million people. In the year 2017 itself, the cost of AD treatment in the USA has been reported to rise to $259 billion. This statistic shows the severity of the disease in the USA which is very much similar across the globe. On the other hand, the treatment remains limited to a few conventional oral medications (approved by FDA). These are mainly acting superficially from mild to the moderate AD...

Rapid disease progression and associated opportunistic infections contribute to high mortality rates among children aged <15 years with human immunodeficiency virus (HIV) infection (1). Antiretroviral therapy (ART) has decreased childhood HIV-associated morbidity and mortality rates over the past decade (2). As accumulating evidence revealed lower HIV-associated mortality with early ART initiation, the World Health Organization (WHO) guidelines broadened ART eligibility for children with HIV infection (2)...
