Significant transcriptome alterations are detected in the brain of patients with amyotrophic lateral sclerosis (ALS), including carriers of the C9orf72 repeat expansion and C9orf72-negative sporadic cases. Recently, the expression of repetitive element transcripts has been associated with toxicity and, while increased repetitive element expression has been observed in several neurodegenerative diseases, little is known about their contribution to ALS. To assess whether aberrant expression of repetitive element sequences are observed in ALS, we analyzed RNA sequencing data from C9orf72-positive and sporadic ALS cases, as well as healthy controls...

Combining anti-catabolic agents with parathyroid hormone (PTH) to enhance bone mass has yielded mixed results in osteoporosis patients. Towards the goal of enhancing the efficacy of these regimens, we tested their utility in combination with loss of the transcription factor Nmp4 since disabling this gene amplifies PTH-induced increases in trabecular bone in mice by boosting osteoblast secretory activity. We addressed whether combining a sustained anabolic response with an anti-catabolic results in superior bone acquisition compared to PTH mono-therapy...

The escalating increase in retirees living beyond their 8th decade brings increased prevalence of aging-related impairments, including locomotor impairment (Parkinsonism) which may affect ~50% of those reaching age 80, but has no confirmed neurobiological mechanism. Lifestyle strategies that attenuate motor decline, and its allied mechanisms, must be identified. Aging studies report little to moderate loss of striatal dopamine (DA) or tyrosine hydroxylase (TH) in nigrostriatal terminals, in contrast to ~70-80% loss associated with bradykinesia onset in Parkinson's disease...

Pan Luo, Dong Liu, Lianjun Guo
Ischemic stroke has many devastating effects within the brain. At the cellular level, excitotoxicity has been a popular pharmacological target for therapeutics. To date, many clinical trials have been performed with drugs that target excitatory neurotransmitter receptors, such as NMDA receptor agonists. The results, however, have been lackluster. Most efforts to understand the impacts of excitotoxicity on the brain have focused primarily on neurons, and to a lesser degree, on gliocytes as cellular targets. Recent evidence suggests that oligodendrocytes (OLGs), the myelin-forming cells in the central nervous system, are damaged by ischemia in a manner completely different from that in neurons...

BACKGROUND: Light therapy (LT) is a non-pharmacological biological treatment that has been used in psychiatry since the 1980s. Previous research has investigated the usage of LT in hospitals. The aim of this study was to examine the pattern of use of LT by office-based physicians. METHODS: A questionnaire was sent by mail to 400 randomly selected doctors in Austria. We made sure that the sample was equally representative of general practitioners (GPs) and psychiatrists, public health service doctors and private doctors, physicians in cities and in the country as well as male and female doctors...

Colorectal cancer (CRC) is one of the leading causes of cancer-related mortality. Recent studies have stated that NOTCH signaling plays an important role in the development and progression of CRC. However, the role of Jagged-2 (JAG2), one of the NOTCH ligands, has not been delineated in colorectal tumorigenesis and drug resistance. In the present study, we have examined the impact of targeting JAG2 on CRC cells. Among all the members of NOTCH ligands, only the expression of JAG2 was found up-regulated in the intestinal tumors of ApcMin/+ mice as compared to the nearby normal mucosa...

Colorectal cancer is the third leading cause of cancer-related deaths in the United States. Treatment of colorectal cancer remains a challenge to clinicians as well as drug developers. Irinotecan, a Camptothecin derivative, is successfully used for the treatment of this rapidly progressing malignancy and finds its place in the first line of therapeutic agents. Irinotecan is also effective in treating SCLC, malignant glioma and pancreatic adenocarcinoma. However, its adverse effects limit its clinical application...

BACKGROUND: The excess mortality in schizophrenia is still a phenomenon insufficiently studied on the cross-national level. It is important to analyse current studies on morality in schizophrenia since significant changes have recently taken place in psychiatric health care systems and guidelines of pharmacological treatment have been developed in European countries. SUBJECTS AND METHODS: This article reviews studies addressing mortality in schizophrenia in Europe that were published in English in the Pubmed database in 2009-2014...

NiaoDuQing (NDQ) granules, a traditional Chinese medicine, has been clinically used in China for over fourteen years to treat chronic kidney disease (CKD). To elucidate the mechanisms underlying the therapeutic benefits of NDQ, we designed an approach incorporating chemoinformatics, bioinformatics, network biology methods, and cellular and molecular biology experiments. A total of 182 active compounds were identified in NDQ granules, and 397 putative targets associated with different diseases were derived through ADME modelling and target prediction tools...

A series of 8-substituted analogues of cyclic ADP-4-thioribose (cADPtR, 3), which is a stable equivalent of Ca2+-mobilizing second messenger cyclic ADP-ribose (cADPR, 1), were designed as potential pharmacological tools for the studies on cADPR-modulated Ca2+ signaling pathways. These 8-amino analogue (8-NH2-cADPtR, 4), 8-azido analogue (8-N3-cADPtR, 5), and 8-chloro analogue (8-Cl-cADPtR, 6) were efficiently synthesized, where the stereoselective N1-β-thioribosyladenine-ring closure reaction via an α/β-equilibrium of the 1-aminothioribose derivative and construction of the characteristic 18-membered pyrophosphate ring by Ag+-promoted activation of a phenyl phosphorothioate-type substrate were the two key steps...

Pharmacological modulation of responses to injury is complicated by the need to deliver multiple drugs with spatiotemporal resolution. Here, a novel controlled delivery system containing three separate compartments with each releasing its contents over different timescales is fabricated. Core-shell electrospun fibers create two of the compartments in the system, while electrosprayed spheres create the third. Utility is demonstrated by targeting the foreign body response to implants because it is a dynamic process resulting in implant failure...

Recently, we have shown that casein glycomacropeptide hydrolysates (GHP) exhibit both anti-inflammatory and anti-oxidative activities in vitro. However, whether heme oxygenase-1 (HO-1) is involved in the cytoprotective effect of GHP against the inflammatory status remains unclear. Therefore, we hypothesized that HO-1 is a potential target of GHP, which mediates its anti-inflammatory effect. Here, GHP inhibited the intracellular reactive oxygen species (ROS) accumulation and NADPH oxidase 2 (NOX2) expression and enhanced reduced glutathione (GSH) levels in LPS-stimulated RAW264...

Yunis-Varón syndrome (YVS) is an autosomal recessive disorder comprising skeletal anomalies, dysmorphism, global developmental delay and intracytoplasmic vacuolation in brain and other tissues. All hitherto-reported pathogenic variants affect FIG4, a lipid phosphatase involved in phosphatidylinositol (3,5)-bisphosphate [PtdIns(3,5)P2] metabolism. FIG4 interacts with PIKfyve, a lipid kinase, via the adapter protein VAC14; all subunits of the resulting complex are essential for PtdIns(3,5)P2 synthesis in the endolysosomal membrane compartment...

REVIEW
Mehdi Rajabi, Shaker A Mousa
A number of anti-angiogenesis drugs have been FDA-approved and are being used in cancer treatment, and a number of other agents are in different stages of clinical development or in preclinical evaluation. However, pharmacologic anti-angiogenesis strategies that arrest tumor progression might not be enough to eradicate tumors. Decreased anti-angiogenesis activity in single mechanism-based anti-angiogenic strategies is due to the redundancy, multiplicity, and development of compensatory mechanism by which blood vessels are remodeled...

Areca catechu L. nut, a well-known toxic traditional herbal medicine, has been widely used to treat various diseases in China and many other Asian countries for centuries. However, to date the in vivo absorption and metabolism of its multiple bioactive or toxic components still remain unclear. In this study, liquid chromatography coupled with tandem mass spectrometry was used to analyze the major components and their metabolites in rat plasma and urine after oral administration of Areca catechu L. nut extract (ACNE)...

Visceral pain is very common and represents a major unmet clinical need for which current pharmacological treatments are often insufficient. Tetrodotoxin (TTX) is a potent neurotoxin that exerts analgesic actions in both humans and rodents under different somatic pain conditions, but its effect has been unexplored in visceral pain. Therefore, we tested the effects of systemic TTX in viscero-specific mouse models of chemical stimulation of the colon (intracolonic instillation of capsaicin and mustard oil) and intraperitoneal cyclophosphamide-induced cystitis...

Opioids remain the standard of care for treating moderate to severe pain resulting from surgery or injury in cases of acute pain, and are recommended for patients who have not responded to nonopioid analgesics. Effective management of pain has an impact on clinical course and often depends on achieving an acceptable balance between opioid efficacy, safety, and tolerability. Common opioid-related adverse events such as nausea and vomiting are associated with an overall lower achievement of effective pain management and patient satisfaction...

Agonism of the 5-HT2C receptor represents one of the most well-studied and clinically-proven mechanisms for pharmacological weight reduction. Selectivity over the closely related 5-HT2A and 5-HT2B receptors is critical as their activation has been shown to lead to undesirable side-effects and major safety concerns. In this communication, we report the development of a new screening paradigm which utilizes an active site mutant D134A 5-HT2C receptor to identify atypical agonist structures. We additionally report the discovery and optimization of a novel class of non-basic heterocyclic amide agonists of 5-HT2C...
