Nurr1 deficiency shortens free running period, enhances photoentrainment to phase advance, and disrupts circadian cycling of the dopamine neuron phenotype.

Behav Brain Res 2021 May 12:113347. Epub 2021 May 12.

East Carolina University, Department of Anatomy and Cell Biology, Brody School of Medicine, Greenville, NC, USA. Electronic address:

Neurological and neuropsychiatric disorders, including addiction, schizophrenia, and Parkinson's disease (PD), involve dysfunction in midbrain dopamine (DA) neurotransmission with severity of disease symptoms and progression associated with disrupted circadian rhythms. The nuclear transcription factor Nurr1, essential for DA neuron (DAN) development, survival, and maintenance, is also known to interact with circadian rhythm regulating clock proteins. In the Nurr1-null heterozygous (+/-) mice, a Nurr1 deficient model which reproduces some of the alterations in DA function found in schizophrenia and PD, we measured, using wheel-running activity, the free running period (tau) and photoperiod entrainment.

Myosteatosis in NAFLD patients correlates with plasma Cathepsin D.

Biomol Concepts 2021 May 15;12(1):27-35. Epub 2021 May 15.

Department of Molecular Genetics, NUTRIM School of Nutrition and Translational Research in Metabolism, Maastricht University Medical Center+, Universiteitssingel 50, 6229ERMaastricht, the Netherlands.

Previously, we have shown that hepatic lipid accumulation induces the secretion of cathepsin D (CTSD), and that plasma CTSD levels are associated with increased inflammation and disease severity in nonalcoholic fatty liver disease (NAFLD). Although it is clear that the liver is a major source of plasma CTSD, it is unknown whether other metabolically active organs such as the muscle, also associate with plasma CTSD levels in NAFLD patients. Therefore, the aim of this study was to explore the relation between lipid accumulation in the muscle (myosteatosis) and plasma CTSD levels in forty-five NAFLD patients. Read More

Incidence, characteristics and clinical profile of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection in patients with pre-existing primary immune thrombocytopenia (ITP) in Spain.

Br J Haematol 2021 May 15. Epub 2021 May 15.

Hospital Universitario Virgen del Rocío, Sevilla, Spain.

Infections are one of the well-known precipitating factors for relapses in patients with immune thrombocytopenia (ITP). Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection can sometimes lead to or be associated with thrombocytopenia due to an increase in peripheral platelet destruction from inflammatory hyperactivation. Currently, we do not know if SARS-CoV-2 infection modifies the natural evolution of chronic or persistent ITP or if previous immunosuppression of patients with ITP influences the incidence and severity of coronavirus disease 2019 (COVID-19) in this group.

WSM419 genes that improve symbiosis between Rm1021 and Jemalong A17 and in other symbiotic systems.

Appl Environ Microbiol 2021 May 14. Epub 2021 May 14.

Institute of Biological Chemistry and School of Molecular Biosciences, Washington State University, Pullman, WA 99164 USA

Some soil bacteria called rhizobia can interact symbiotically with legumes in which they form nodules on the plant roots where they can reduce atmospheric dinitrogen to ammonia, a form of nitrogen that can be used by growing plants. Rhizobia/plant combinations can differ in how successful this symbiosis is- Rm1021 forms a relatively ineffective symbiosis with Jemalong A17 but WSM419 is able to support more vigorous plant growth. Using proteomic data from free-living and symbiotic WSM419, we previously identified a subset of proteins that were not closely related to any Rm1021 proteins and speculated that adding one or more of these proteins to Rm1021 would increase its effectiveness on A17.
