The UPR-PERK pathway is not a promising therapeutic target for mutant SOD1-induced ALS.

Neurobiol Dis 2019 Mar 26;127:527-544. Epub 2019 Mar 26.

Department of Neurology, The University of Chicago Center for Peripheral Neuropathy, The University of Chicago, Chicago, IL 60637, United States. Electronic address:

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease, characterized by motor neuron death in the brain and spinal cord. Mutations in the Cu/Zn superoxide dismutase (SOD1) gene account for ~20% of all familial ALS forms, corresponding to 1%-2% of all ALS cases. One of the suggested mechanisms by which mutant SOD1 (mtSOD1) exerts its toxic effects involves intracellular accumulation of abnormal mtSOD1 aggregates, which trigger endoplasmic reticulum (ER) stress and activate its adaptive signal transduction pathways, including the unfolded protein response (UPR).

J Peripher Nerv Syst 2019 Mar 13. Epub 2019 Mar 13.

Department of Neurology, Concord Repatriation General Hospital, Sydney, New South Wales, Australia.

Hereditary sensory and autonomic neuropathy type I (HSAN-1) is an autosomal dominant sensory neuropathy occurring secondary to mutations in the SPTLC1 and SPTLC2 genes. We present two generations of a single family with Ser384Phe mutation in the SPTLC2 gene located on chromosome 14q24 characterized by a typical HSAN-1c presentation, with additional findings upper motor neuron signs, early demyelinating features on nerve conduction studies, and type II juxtafoveal retinal telangiectasias also known as macular telangiectasias (MacTel II). Although HSAN1 is characterized as an axonal neuropathy, demyelinating features were identified in two subjects on serial nerve conduction studies comprising motor conduction block, temporal dispersion, and prolongation of F-waves.

Ultrastructure in Transthyretin Amyloidosis: From Pathophysiology to Therapeutic Insights.

Biomedicines 2019 Feb 5;7(1). Epub 2019 Feb 5.

Department of Neurology, Nagoya University Graduate School of Medicine, Nagoya 466-8550, Japan.

Transthyretin (TTR) amyloidosis is caused by systemic deposition of wild-type or variant amyloidogenic TTR (ATTRwt and ATTRv, respectively). ATTRwt amyloidosis has traditionally been termed senile systemic amyloidosis, while ATTRv amyloidosis has been called familial amyloid polyneuropathy. Although ATTRwt amyloidosis has classically been regarded as one of the causes of cardiomyopathy occurring in the elderly population, recent developments in diagnostic techniques have significantly expanded the concept of this disease.

Enhanced axonal Neuregulin-1 type-III signaling ameliorates neurophysiology and hypomyelination in a Charcot-Marie-Tooth type 1B mouse model.

Hum Mol Genet 2018 Nov 27. Epub 2018 Nov 27.

DIBIT, Divisions of Genetics and Cell Biology.

Charcot-Marie-Tooth neuropathies (CMTs) are a group of genetic disorders that affect the peripheral nervous system (PNS) with heterogeneous pathogenesis and no available treatment. Axonal Neuregulin 1 type III (Nrg1TIII) drives peripheral nerve myelination by activating downstream signaling pathways such as PI3K/Akt and MAPK/Erk that converge on master transcriptional regulators of myelin genes, such as Krox20. We reasoned that modulating Nrg1TIII activity may constitute a general therapeutic strategy to treat CMTs that are characterized by reduced levels of myelination. Read More

Anthracycline and taxane-based chemotherapy versus docetaxel and cyclophosphamide in the adjuvant treatment of HER2-negative breast cancer patients: a systematic review and meta-analysis of randomized controlled trials.

Breast Cancer Res Treat 2019 Feb 21;174(1):27-37. Epub 2018 Nov 21.

Department of Medical Oncology, Institut Jules Bordet and Université Libre de Bruxelles (ULB), Boulevard de Waterloo 121, 1000, Brussels, Belgium.

Purpose: Standard adjuvant chemotherapy for HER2-negative breast cancer consists generally in an anthracycline and taxane-based regimen (A+T). The TC (docetaxel and cyclophosphamide) regimen arises as a potential alternative, although individual randomized controlled trials (RCTs) could not demonstrate the non-inferiority of TC over A+T. This is a systematic review and meta-analysis of RCTs comparing 6 cycles of TC versus sequential A+T in the adjuvant treatment of HER2-negative breast cancer. Read More

The conceptual introduction of the "demyelinating Schwann cell" in peripheral demyelinating neuropathies.

Glia 2019 04 30;67(4):571-581. Epub 2018 Oct 30.

INSERM U1051, Institut des Neurosciences de Montpellier (INM), Université de Montpellier, Montpellier, France.

Myelinating Schwann cells undergo irreversible demyelination in many demyelinating neuropathies that show complete demyelination of the internode. Dedifferentiation, reprogramming, and myelin clearance processes-which are specifically discussed in this article-appear to be shared by various demyelinating peripheral conditions, such as Wallerian degeneration, immune-mediated, and toxic demyelinating diseases. We propose to introduce the concept of the "demyelinating Schwann cell (DSC)" as a novel cell phenotype, which has specific properties required for myelin sheath clearance. Read More

Carboplatin/Paclitaxel Induction in Ovarian Cancer: The Finer Points.

Oncology (Williston Park) 2018 08;32(8):418-20, 422-4

The carboplatin/paclitaxel doublet remains the chemotherapy backbone for the initial treatment of ovarian cancer. This two-drug regimen, with carboplatin dosed using the Calvert formula, yielded convincing noninferior outcomes when compared with the prior, more toxic, regimen of cisplatin/paclitaxel. Carboplatin's dose-limiting toxicity is thrombocytopenia; however, when this drug is properly dosed and combined with paclitaxel, the doublet's cycle 1 dose in chemotherapy-naive women is generally safe.

Chronic hyperglycemia mediated physiological alteration and metabolic distortion leads to organ dysfunction, infection, cancer progression and other pathophysiological consequences: An update on glucose toxicity.

Biomed Pharmacother 2018 Nov 8;107:306-328. Epub 2018 Aug 8.

Department of Physiology, University of Gour Banga, Mokdumpur, Malda 732103, India. Electronic address:

Chronic exposure of glucose rich environment creates several physiological and pathophysiological changes. There are several pathways by which hyperglycemia exacerbate its toxic effect on cells, tissues and organ systems. Hyperglycemia can induce oxidative stress, upsurge polyol pathway, activate protein kinase C (PKC), enhance hexosamine biosynthetic pathway (HBP), promote the formation of advanced glycation end-products (AGEs) and finally alters gene expressions.

The Antidiabetic Drug Liraglutide Minimizes the Non-Cholinergic Neurotoxicity of the Pesticide Mipafox in SH-SY5Y Cells.

Neurotox Res 2019 Jan 7;35(1):150-159. Epub 2018 Aug 7.

Departamento de Análises Clínicas, Toxicológicas e Bromatológicas, Faculdade de Ciências Farmacêuticas de Ribeirão Preto-FCFRP, Universidade de São Paulo, USP, Avenida do Café s/n, Ribeirão Preto, SP, 14040-903, Brazil.

Organophosphorus (OPs) compounds have been widely used in agriculture, industry, and household, and the neurotoxicity induced by them is still a cause of concern. The main toxic mechanism of OPs is the inhibition of acetylcholinesterase (AChE); however, the delayed neuropathy induced by OPs (OPIDN) is mediated by other mechanisms such as the irreversible inhibition of 70% of NTE activity (neuropathy target esterase) that leads to axonal degeneration. Liraglutide is a long-lasting GLP-1 analog clinically used as antidiabetic. Read More

Mitochondrial Impairment in Antibiotic Induced Toxic Optic Neuropathies.

Curr Eye Res 2018 Oct 7;43(10):1199-1204. Epub 2018 Aug 7.

a Department of Ophthalmology , University of California , Irvine , CA , USA.

There is growing evidence for the role of mitochondrial dysfunction in the toxic optic neuropathies. Due to the structural similarities between antibiotic targets and mitochondrial machinery, several antibiotics known to cause optic neuropathy have deleterious effects on mitochondrial function. We review the literature on the prevalence, clinical manifestations, and management of antibiotic induced toxic optic neuropathies. Read More

Emerging therapies for mitochondrial diseases.

Essays Biochem 2018 07 20;62(3):467-481. Epub 2018 Jul 20.

Department of Neurology, Columbia University Medical Center, New York, NY, U.S.A.

For the vast majority of patients with mitochondrial diseases, only supportive and symptomatic therapies are available. However, in the last decade, due to extraordinary advances in defining the causes and pathomechanisms of these diverse disorders, new therapies are being developed in the laboratory and are entering human clinical trials. In this review, we highlight the current use of dietary supplement and exercise therapies as well as emerging therapies that may be broadly applicable across multiple mitochondrial diseases or tailored for specific disorders.

Steroid Treatment of Optic Neuropathies.

Asia Pac J Ophthalmol (Phila) 2018 Jul-Aug;7(4):218-228. Epub 2018 Jul 2.

Department of Ophthalmology and Visual Sciences, Washington University School of Medicine, St. Louis, Missouri.

The etiologies of optic neuropathy include inflammation, ischemia, toxic and metabolic injury, genetic disease, and trauma. There is little controversy over the practice of using steroids in the treatment of optic neuritis--it is well established that intravenous steroid treatment can speed visual recovery but does not alter final visual function. However, there is controversy surrounding the acceptable routes of administration, dosage, and course of treatment. Read More
