The role of human C5a as a non-genomic target in corticosteroid therapy for management of severe COVID19.

Comput Biol Chem 2021 Apr 5;92:107482. Epub 2021 Apr 5.

Chemical Biology Laboratory, School of Basic Sciences, Indian Institute of Technology Bhubaneswar, Odisha, 752050, India. Electronic address:

Complement system plays a dual role; physiological as well as pathophysiological. While physiological role protects the host, pathophysiological role can substantially harm the host, by triggering several hyper-inflammatory pathways, referred as "hypercytokinaemia". Emerging clinical evidence suggests that exposure to severe acute respiratory syndrome coronavirus-2 (SARS-CoV2), tricks the complement to aberrantly activate the "hypercytokinaemia" loop, which significantly contributes to the severity of the COVID19.

Tombusviruses orchestrate the host endomembrane system to create elaborate membranous replication organelles.

Curr Opin Virol 2021 Apr 9;48:30-41. Epub 2021 Apr 9.

Department of Plant Pathology, University of Kentucky, Lexington, KY 40546, USA.

Positive-strand RNA viruses depend on intensive manipulation of subcellular organelles and membranes to create unique viral replication organelles (VROs), which represent the sites of robust virus replication. The host endomembrane-based protein-trafficking and vesicle-trafficking pathways are specifically targeted by many (+)RNA viruses to take advantage of their rich resources. We summarize the critical roles of co-opted endoplasmic reticulum subdomains and associated host proteins and COPII vesicles play in tombusvirus replication. Read More

The potential role of oxytocin in addiction: What is the target process?

Curr Opin Pharmacol 2021 Apr 9;58:8-20. Epub 2021 Apr 9.

Department of Biomedical Sciences, University of Cagliari, Monserrato, Cagliari 09042, Italy. Electronic address:

Oxytocin regulates a variety of centrally-mediated functions, ranging from socio-sexual behavior, maternal care, and affiliation to fear, stress, anxiety. In the past years, both clinical and preclinical studies characterized oxytocin for its modulatory role on reward-related neural substrates mainly involving the interplay with the mesolimbic and mesocortical dopaminergic pathways. This suggests a role of this nonapeptide on the neurobiology of addiction raising the possibility of its therapeutic use. Read More

Comparative Metabolic Modeling of Multiple Sulfate-reducing Prokaryotes Reveals Versatile Energy Conservation Mechanisms.

Biotechnol Bioeng 2021 Apr 12. Epub 2021 Apr 12.

Department of Civil and Environmental Engineering, The Hong Kong University of Science and Technology, Clear Water Bay, Hong Kong, China.

Sulfate-reducing prokaryotes (SRPs) are crucial participants in the cycling of sulfur, carbon, and various metals in the natural environment and in engineered systems. Despite recent advances in genetics and molecular biology bringing a huge amount of information about the energy metabolism of SRPs, little effort has been made to link this important information with their biotechnological studies. This study aims to construct multiple metabolic models of SRPs that systematically compile genomic, genetic, biochemical, and molecular information about SRPs to study their energy metabolism.

CXCR4 allows T cell acute lymphoblastic leukemia to escape from JAK1/2 and BCL2 inhibition through CNS infiltration.

Leuk Lymphoma 2021 Apr 11:1-11. Epub 2021 Apr 11.

Department of Pediatrics, University of Wisconsin School of Medicine and Public Health, Madison, WI, USA.

Targeting the JAK/STAT and BCL2 pathways in patients with relapsed/refractory T cell acute lymphoblastic leukemia (T-ALL) may provide an alternative approach to achieve clinical remissions. Ruxolitinib and venetoclax show a dose-dependent effect on T-ALL individually, but combination treatment reduces survival and proliferation of T-ALL . Using a xenograft model, the combination treatment fails to improve survival, with death from hind limb paralysis. Read More

Combined effects of a ketogenic diet and exercise training alter mitochondrial and peroxisomal substrate oxidative capacity in skeletal muscle.

Am J Physiol Endocrinol Metab 2021 Apr 12. Epub 2021 Apr 12.

Skeletal Muscle Metabolism, Pennington Biomedical Research Center, United States.

Ketogenic diets (KD) are reported to improve body weight, fat mass, and exercise performance in humans. Unfortunately, most rodent studies have used a low-protein KD, which does not recapitulate diets used by humans. Since skeletal muscle plays a critical role in responding to macronutrient perturbations induced by diet and exercise, the purpose of this study was to test if a normal-protein KD (NPKD) impacts shifts in skeletal muscle substrate oxidative capacity in response to exercise training (ExTr).

Mol Reprod Dev 2021 Apr 12. Epub 2021 Apr 12.

9.Baby, Family and Fertility Center, Bologna, Italy.

Embryo development requires orchestrated events, finely regulated at the molecular and cellular level by mechanisms which are progressively emerging from animal studies. With progress in genetic technologies-such as genome editing and single-cell RNA analysis-we can now assess embryo gene expression with increased precision and gain new insights into complex processes until recently difficult to explore. Multiple genes and regulative pathways have been identified for each developmental stage. Read More

Examining sources and pathways of phosphorus transfer in a ditch-drained field with concentration -discharge relationships and isotope hydrograph separation.

J Environ Qual 2021 Apr 11. Epub 2021 Apr 11.

Department of Plant and Soil Sciences, University of Delaware, 531 S. College Ave., Newark, DE, 19716.

Understanding the processes that mobilize and transport dissolved phosphorus (P) during storms is critical to managing P in flat landscapes with open ditch drainage and legacy soil P. In this study, we employed routine baseflow monitoring and intensive storm sampling at a ditch-drained site on Maryland's Lower Eastern Shore (July 2017 to September 2018) to assess whether concentration-discharge (C-Q) relationships and chemical and isotopic hydrograph separation could provide insight into the processes that mobilize and transport dissolved P in ditch drainage. Using a segmented regression model, we determined that long-term C-Q relationships for dissolved P differed above and below a discharge threshold of 6. Read More

Morphea: progress to date and the road ahead.

Ann Transl Med 2021 Mar;9(5):437

Department of Dermatology, University of Texas Southwestern Medical Center, Dallas, Texas, USA.

Morphea is a rare autoimmune condition causing inflammation and sclerosis of the skin and underlying soft tissue. It is characterized by periods of activity (inflammation admixed with fibrosis), ultimately resulting in permanent damage (pigment change and tissue loss). Damage resulting from unchecked activity can lead to devastating, permanent cosmetic and functional sequelae including hair loss; cutaneous, soft tissue and bony atrophy; joint contractures; and growth restriction of the affected body site in children.

Rosavin suppresses osteoclastogenesis and by blocking the nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) and mitogen-activated protein kinase (MAPK) signaling pathways.

Ann Transl Med 2021 Mar;9(5):383

Department of Oral and Craniofacial Surgery, Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai, China.

Background: Bone homeostasis is mediated by osteoblast-related bone formation and osteoclast-related resorption. The imbalance of bone homeostasis due to excessive osteoclastogenesis or reduced osteogenesis can result in various disorders, such as postmenopausal osteoporosis (PMOP). The receptor activator of nuclear factor-κB ligand (RANKL)-induced nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) and mitogen-activated protein kinase (MAPK) pathways are essential in osteoclastogenesis.
