Various novel androgen receptor (AR) targeting drugs have been developed recently and have shown beneficial effects on survival in patients with metastatic castration-resistant prostate cancer (mCRPC). However, no consensus has been reached regarding which of these agents provides the most favorable oncological outcomes. Here, we aimed to compare the efficacy of novel AR-targeted agents by performing a network meta-analysis of randomized controlled trials (RCTs). We included eight RCTs for men with mCRPC treated with one of the AR targeting agents: abiraterone acetate, enzalutamide, or orteronel...

PEGylated arginine deiminase (ADI-PEG 20) is being investigated in clinical studies in arginine auxotrophic cancers and is well-tolerated. The anti-tumor properties of ADI-PEG 20 have been extensively investigated - ADI-PEG 20 inhibits the growth of auxotrophic cancers in vitro and in vivo - however, its impact on immune cells is largely unknown. Here we report the potential impact of ADI-PEG 20 on the tumor immune microenvironment. ADI-PEG 20 induced immunosuppressive programmed death-ligand 1 expression on some cancer cells in vitro, but the magnitude of the increase was cell line dependent and in most relatively small...

Hepatocellular carcinoma (HCC) is the sixth most common cancer. The Warburg effect is an important way by which HCC adapts to a hypoxic environment. The aim of the present study was to determine whether and how galangin reverses the Warburg effect in HCC cells. We treated three HCC cell lines, HepG2, Hep3B and PLC/PRF/5 with galangin for 24h, respectively. Cell proliferation was measured with MTT assay. Glucose uptake, lactate production and the oxygen consumption were measured. Pyruvate kinase activities were detected by measuring the consumption of NADH, and glycolytic pathway-related proteins were measured by Western blotting...

In this era of increased obesity and diabetes prevalence, the browning of white adipose tissue (WAT) has emerged as a promising therapeutic target to induce weight loss and improve insulin sensitivity in this population. The browning process entails a shift in the WAT from primarily storing excess energy to the dissipation of energy as heat. However, this idealistic view of WAT browning being the saviour of the metabolic syndrome has been criticized by studies in burns and cancer patients that have shown browning to be detrimental rather than being beneficial...

Neurotrophic factors, a family of secreted proteins that support the growth, survival and differentiation of neurons, have been intensively studied for decades due to the powerful and diverse effects on neuronal physiology, as well as their therapeutic potential. Such efforts have led to a detailed understanding on the molecular mechanisms of neurotrophic factor signaling. One member, brain-derived neurotrophic factor (BDNF) has drawn much attention due to its pleiotropic roles in the central nervous system and implications in various brain disorders...

Doxorubicin (Dox) is an effective chemotherapeutic agent used in the treatment of various cancers. Its clinical use is often limited due to its potentially fatal cardiotoxic side effect. Increasing evidence indicates that tumour protein p53 (p53), adenosine monophosphate-activated protein kinase (AMPK), nucleoporin p62 (p62), and the mammalian target of rapamycin (mTOR) are critical mediators of Dox-induced apoptosis, and subsequent dysregulation of autophagy. Aspalathin, a polyphenolic dihydrochalcone C-glucoside has been shown to activate AMPK while decreasing the expression of p53...

Axial spondyloarthritis (AxSpA) is an inflammatory spondyloarthritis (SpA) that has significant impact on a patient's life. Symptoms, including fatigue, sleep problems, depression, and sexual dysfunction, can profoundly impact health-related quality of life (HRQoL) and limit work, leisure, and daily activities. Available therapies effectively manage pain and inflammation in early-stage disease, but patients often continue to experience impaired HRQoL. Thus, there remains a need for new therapies with novel mechanisms that can stop disease progression, potentially reverse damage caused by AxSpA and improve HRQoL in patients with AxSpA...

Infectious diseases are resulted from the invasion of an organism's body tissues by multiple disease-causing agents. It has been demonstrated that the occurrence and development of infectious diseases are closely associated with the functional status of immune system. Cytokines play significant roles in modulating the host immune response to the clearance of pathogenic microorganisms and maintaining immune homeostasis. Interleukin-35 (IL-35), as a newly identified member of IL-12 family, exerts suppressive effect on immune response by means of a specific pattern...

In Germany, micropollutants that (may) occur in drinking water are assessed by means of the health-related indicator value (HRIV concept), developed by the German Federal Environment Agency. This concept offers five threshold values (≤ 0.01 to ≤ 3 μg l(-1)) depending on availability and completeness of data regarding genotoxicity, neurotoxicity, and germ cell-damaging potential. However, the HRIV concept is yet lacking integration of endocrine disruptors as one of the most prominent toxicological concerns in water bodies, including drinking water...

The direct and efficient conversion of alcohols into amines is a pivotal transformation in chemistry. Here, we present an artificial, oxidation-reduction, biocatalytic network that employs five enzymes (alcohol dehydrogenase, NADP-oxidase, catalase, amine dehydrogenase and formate dehydrogenase) in two concurrent and orthogonal cycles. The NADP-dependent oxidative cycle converts a diverse range of aromatic and aliphatic alcohol substrates to the carbonyl compound intermediates, whereas the NAD-dependent reductive aminating cycle generates the related amine products with >99% enantiomeric excess (R) and up to >99% conversion...

The major risk factor for Klebsiella liver abscess (KLA) is type 2 diabetes mellitus (DM), but the immunological mechanisms involved in the increased susceptibility are poorly defined. We investigated the responses of neutrophils and peripheral blood mononuclear cells (PBMCs) to hypervirulent Klebsiella pneumoniae (hvKP), the causative agent of KLA. DNA and myeloperoxidase levels were elevated in the plasma of KLA patients compared to uninfected individuals indicating neutrophil activation, but diabetic status had no effect on these neutrophil extracellular trap (NET) biomarkers in both subject groups...
