The critical role of microRNAs in stress response: therapeutic prospect and limitation.

Pharmacol Res 2018 Dec 13. Epub 2018 Dec 13.

Department of Pharmacy, Xiangya Hospital, Central South University, Changsha, 410008, China; National Clinical Research Center for Geriatric Disorders (XIANGYA), Xiangya Hospital, Central South University, Changsha, 410008, Hunan, China. Electronic address:

Stress response refers to the systemic nonspecific response upon exposure to strong stimulation or chronic stress, such as severe trauma, shock, infection, burn, major surgery or improper environment, which disturb organisms and damage their physical and psychological health. However, the pathogenesis of stress induced disorder remains complicated and diverse under different stress exposure. Recently, studies have revealed a specific role of microRNAs (miRNAs) in regulating cellular function under different types of stress, suggesting a significant role in the treatment and prevention of stress-related diseases, such as stress ulcer, posttraumatic stress disorder, stress-induced cardiomyopathy and so on.

C-terminus of heat shock protein 60 can activate macrophages by lectin-like oxidized low-density lipoprotein receptor 1.

Biochem Biophys Res Commun 2018 Dec 12. Epub 2018 Dec 12.

Department of Forensic Medicine, School of Basic Medical Sciences, Fudan University, Shanghai, 200032, China. Electronic address:

Immune responses against antigens generally require an efficient activation of antigen-presenting cells (APCs). Currently, the targeting of vaccine antigens to APCs has emerged as a promising strategy for boosting vaccine immunogenicity. Here, we reported that the C-terminus of heat shock protein 60 (HSP60C) can activate mouse peritoneal macrophages to secret a series of cytokines, and phosphorylation of p38 mitogen-activated protein kinase (MAPK) and NF-κB p65 was involved in the pathway.

Granularity impact on hotspot formation and local chemistry in shocked nanostructured RDX.

Authors:
X Bidault N Pineau

J Chem Phys 2018 Dec;149(22):224703

CEA/DAM/DIF, F-91297 Arpajon, France.

The nanostructuration of energetic materials results in interesting properties. In particular, the detonation of carbon-rich explosives leads to the formation of nanodiamonds, the size of which is linked to the initial size of the explosive nanograins. This correlation could come from the role played by the granularity in the shock properties, especially the local temperature, which could be enhanced when the shock front crosses the various interfaces and nanoporosities of the material.

Inhibition of Hepatitis C replication by targeting the molecular chaperone Hsp90 - synthesis and biological evaluation of 4,5,6,7-tetrahydrobenzo[1,2-d]thiazole derivatives.

ChemMedChem 2018 Dec 13. Epub 2018 Dec 13.

University of Helsinki, Centre for Drug Research, Division of Pharmaceutical Biosciences, Viikinkaari 4, 00014, Helsinki, FINLAND.

Cellular chaperones that belong to the heat-shock protein 90 (Hsp90) family are a prerequisite for successful viral propagation for most viruses. The hepatitis C virus (HCV) uses Hsp90 for maturation, folding and modification of viral proteins. Based on our previous discovery that marine alkaloid analogues with 4,5,6,7-tetrahydrobenzo[1,2-d]thiazole-2-amine structure show inhibition of HCV replication and potential binding to Hsp90, a series of twelve novel compounds based on this scaffold was designed and synthesized.

Transcriptome Analysis Reveals Candidate Genes for Cold Tolerance in Drosophila ananassae.

Division of Evolutionary Biology, Faculty of Biology, LMU Munich, Grosshaderner Str. 2, 82152 Planegg-Martinsried, Germany.

Coping with daily and seasonal temperature fluctuations is a key adaptive process for species to colonize temperate regions all over the globe. Over the past 18,000 years, the tropical species Drosophila ananassae expanded its home range from tropical regions in Southeast Asia to more temperate regions. Phenotypic assays of chill coma recovery time (CCRT) together with previously published population genetic data suggest that only a small number of genes underlie improved cold hardiness in the cold-adapted populations.

Background: A systolic blood pressure (SBP) lower than the heart rate (HR) could indicate a poor condition in trauma patients. In such scenarios, the reversed shock index (RSI) is < 1, as calculated by the SBP divided by the HR. This study aimed to clarify whether RSI could be used to identify high-risk adult patients with isolated traumatic brain injury (TBI). Read More

Exploring the potential role of mesocorticolimbic circuitry in motivation for and adherence to chronic pain self-management interventions.

Neurosci Biobehav Rev 2018 Dec 10. Epub 2018 Dec 10.

Department of Psychiatry and Behavioral Sciences, Johns Hopkins University, 5510 Nathan Shock Drive, Suite 101, Baltimore, MD, USA.

Adherence to pain self-management strategies is associated with favorable psychobehavioral outcomes among individuals with chronic pain. Substantive adherence to treatments teaching these adaptive skills proves challenging, resulting in poor individual and societal outcomes. Evidence demonstrates motivation for behavior change as a key predictor of treatment adherence. Read More

Evaluation of 5-HT receptor antagonism for the treatment of anxiety, depression, and schizophrenia through the use of receptor-deficient mice.

Behav Brain Res 2018 Dec 10. Epub 2018 Dec 10.

Neuroscience Discovery Research, Lilly Research Laboratories, Eli Lilly and Company, Indianapolis, IN, 46285, USA. Electronic address:

The 5-HT receptor is the most recently identified receptor subtype within a family of 5-HT receptors activated by the neurotransmitter serotonin. There has been significant interest in investigating the potential role of this receptor in psychiatric disorders including depression, anxiety, and schizophrenia. Behaviors of 5-HT +/+ (wild-type or WT) and 5-HT -/- (receptor knockout or KO) mice were compared across 10 different assays (7 for anxiety, 1 for depression, 2 for psychosis) to identify differences that could indicate clinical potential for 5-HT receptor antagonism.

Intracellular Heat Shock Protein 70 Deficiency in Pulmonary Fibrosis.

Am J Respir Cell Mol Biol 2018 Dec 13. Epub 2018 Dec 13.

Medical University of South Carolina, Medicine, Charleston, South Carolina, United States.

Idiopathic Pulmonary Fibrosis (IPF) pathogenesis has been postulated to involve a variety of mechanisms associated with the aging process, including loss of protein homeostasis (proteostasis). Heat shock proteins (Hsp) are cellular chaperones that serve a number of vital maintenance and repair functions, including the regulation of proteostasis. Previously published data have implicated Hsp70 in the development of pulmonary fibrosis in animal models. Read More

Shock - Classification and Pathophysiological Principles of Therapeutics.

Curr Cardiol Rev 2018 Dec 12. Epub 2018 Dec 12.

Department of Cardiology Bluhm Cardiovascular Institute Feinberg School of Medicine Northwestern University Medical Center, Chicago, Illinois, IL. United States.

The management of patients with shock is extremely challenging because of the myriad of possible clinical presentations in cardiogenic shock, septic shock and hypovolemic shock and the limitations of contemporary therapeutic options. The treatment of shock includes the administration of endogenous catecholamines (epinephrine, norepinephrine, and dopamine) as well as various vasopressor agents that have shown efficacy in the treatment of the various types of shock. In addition to the endogenous catecholamines, dobutamine, isoproterenol, phenylephrine, and milrinone have served as the mainstays of shock therapy for several decades. Read More

HSP70 Inhibitors Reduce The Osteoblast Migration By Epidermal Growth Factor.

Curr Mol Med 2018 Dec 12. Epub 2018 Dec 12.

Department of Pharmacology, Gifu University Graduate School of Medicine, Gifu. Japan.

Background: We have recently reported that epidermal growth factor (EGF) induces migration of osteoblast-like MC3T3-E1 cells through the activation of p44/p42 mitogen-activated protein (MAP) kinase, p38 MAP kinase, stress-activated protein kinase/ c-Jun N-terminal kinase (SAPK/JNK) and Akt. Furthermore, we demonstrated that heat shock protein 70 (HSP70) down-regulates the transforming growth factor-β-stimulated vascular endothelial growth factor synthesis via suppression of p38 MAP kinase in osteoblast-like MC3T3-E1 cells. However, the exact role of HSP70 underlying osteoblast migration is not fully elucidated. Read More
