As the population ages, the incidence and prevalence of neurodegenerative disorders will continue to increase. Persons with neurodegenerative disease frequently experience sleep disorders, which not only affect quality of life, but potentially accelerate progression of the disease. Unfortunately, pharmacological interventions are often futile or have adverse effects. Therefore, investigation of non-pharmacological

Brain metastases manifest the advanced stage of breast cancer disease with poor prognosis for patient survival. Recent reports demonstrate that some therapeutic agents can activate the expression of several breast cancer-associated genes, whose products are involved in the onset and development of brain metastases. In this study, we discovered a functional link between KISS1 and E-cadherin that could

Enhancing the sensitivity of hepatocellular carcinoma (HCC) cells to sorafenib (SFN) is an essential clinical bottleneck to be solved. Here we report that the expression of CD47 negatively correlated with HCC sensitivity to SFN. The microbiota-derived Staphylococcal superantigen-like protein 6 (SSL6) inhibited CD47 and promoted SFN-induced apoptosis of HCC cells Huh-7 and MHCC97H. Mechanistically,

Serrated polyps are a clinically and molecularly heterogeneous group of lesions that can contribute to the development of colorectal cancers (CRCs). However, the molecular mechanism underlying the development of serrated lesions is still not well understood. Here, we combined multiple approaches to analyze the genetic alterations in 86 colorectal adenomas (including 35 sessile serrated lesions, 15

Despite its efficacy in solid tumours, in particular HER2+ breast cancer, HER2‐targeted therapy has given rise to disappointing results in non‐small cell lung cancer (NSCLC).

Chronic obstructive pulmonary disease (COPD) and lung cancer are two major diseases of the lung with high rate of mortality, mostly among tobacco smokers.

Material and Methods The Laboratory Information System (LIS) automatically registered s-vitamin B12 when not ordered by General

Cochlear implants (CIs) are considered the most successful neuroprosthesis as they enable speech comprehension in the majority of half a million CI users suffering from sensorineural hearing loss. By electrically stimulating the auditory nerve, CIs constitute an interface re‐connecting the brain and the auditory scene, providing the patient with information regarding the latter. However, since electric

Mwandigha et al. have presented an interesting case and accompanying simulation studies to explore issues of truncation on count data in a cluster randomized setting.1 The results support the notion that researchers planning these complex cluster randomized trials (CRTs) consider exploring the impact of this truncation in sample size and power calculations early on to avoid underpowered studies. Although

Coenzyme A (CoA) is the predominant acyl carrier in mammalian cells and a cofactor that plays a key role in energy and lipid metabolism. CoA and its thioesters (acyl-CoAs) regulate a multitude of metabolic processes at different levels: as substrates, allosteric modulators, and via post-translational modification of histones and other non-histone proteins. Evidence is emerging that synthesis and degradation

Understanding of the molecular basis of host cell-miRNA interactions is prerequisite to the successful application of miRNAs as potential therapeutic agents. We studied the morphological and molecular consequences of over expression of three sequence divergent miRNAs previously implicated in the mesenchymal-to-epithelial transition process (MET) in three distinct mesenchymal-like cancer cell lines

The hepatitis B virus (HBV) is a major cause of hepatocellular carcinoma (HCC), partly driven by viral integration and specific oncogenic HBV variants. However, the biological significance of HBV genomes within lymphoid cells (i.e., peripheral blood mononuclear cells, PBMCs) is unclear. Here, we collected available plasma, PBMC, liver, and tumor from 52 chronic HBV (CHB) carriers: 32 with HCC, 19 without

Background & Aims Quantification of anti-HBs and anti-HBc predicts the risk of HBV reactivation (HBVr) in lymphoma patients receiving rituximab treatment. However, it remains unclear whether the quantification is predictive of HBVr in leukemia patients undergoing immunosuppression. Methods and patients: Clinical and laboratory data of the leukemia patients with resolved HBV infection diagnosed between

The IκB‐Kinase (IKK)‐NF‐κB signalling pathway plays a multifaceted role in inflammatory bowel disease (IBD): on the one hand, it protects from apoptosis; on the other, it activates transcription of numerous inflammatory cytokines and chemokines. Although several murine models of IBD rely on disruption of IKK‐NF‐κB signalling, these involve either knockouts of a single family‐member of NF‐κB, or of

Direct quantification of exhausted T cells in human cancer is lacking, and its predictive value for checkpoint‐based treatment remains poorly investigated. We sought to systematically characterize the pan‐cancer landscape and molecular hallmarks of T cell dysfunction for the purpose of precision immunotherapy. Here, we defined a transcriptional signature for T cell exhaustion through analyzing differential

A targeted, bottom-up proteomic assay was developed for the qualitative detection of apolipoprotein L1 (ApoL1) protein variants (G0, G1, and G2) in blood plasma for identification of high and low renal risk genotypes. Following trypsin digestion of liquid or dry plasma, surrogate peptides specific to each ApoL1 variant were detected by liquid chromatography-tandem mass spectrometry along with two surrogate

Mutation of the androgen receptor (AR) gene on the X chromosome (Xq11.2q12) is the main cause of AIS. Methods By phenotype evaluation, hormone test, ultrasound

Abstract The exposome represents the totality of life course environmental exposures (including lifestyle and other non-genetic factors), from the prenatal period onwards. This holistic concept of exposure provides a new framework to advance the understanding of complex and multifactorial diseases. Prospective pregnancy and birth cohort studies provide a unique opportunity for exposome research as

Obtaining diagnostic specimens, notably to monitor disease course in cancer patients undergoing therapy, is an emerging area of research, however, with few clinical implications so far in the field of Neuro-oncology. Specifically for patients with primary brain tumors where repeat biosampling from the tumor and clinical decision making based on neuroimaging alone remain challenging, this area may assume

BK polyomavirus (BKPyV) is a ubiquitous pathogen in the human population that is asymptomatic in healthy individuals, but can be life-threatening in those undergoing kidney transplant. To-date, no vaccines or anti-viral therapies are available to treat human BKPyV infections. New therapeutic strategies are urgently required. In this study, using a rational pharmacological screening regimen of known

The ongoing threat of seasonal and pandemic influenza to human health requires antivirals that can effectively supplement existing vaccination strategies. The M2 protein of influenza A virus (IAV) is a proton-gated, proton-selective ion channel that is required for virus replication and is an established antiviral target. While licensed adamantane-based M2 antivirals have been historically used, M2

Abscisic acid (ABA) regulates plant responses to different stimuli including viral infections through two different defense mechanisms; the antiviral RNA silencing pathway and callose accumulation. In some pathosystems, induction of these defense mechanisms is stronger in plants with resistance (R)-genes than in more susceptible plants. Mutants in several RNA silencing genes are hypersensitive to ABA

Non‐melanoma skin cancer (NMSC) is characterized by a strong desmoplastic reaction, largely responsible for cancer aggressiveness. Within the tumour microenvironment, cancer‐associated fibroblasts (CAFs) play a key role in tumour progression, secretion of extracellular matrix proteins and recruitment of immunosuppressive cells. However, pathways involved in acquisition of CAF phenotype remain unclear
