Brain-derived neurotrophic factor precursor in the immune system is a novel target for treating multiple sclerosis.

Brain-derived neurotrophic factor precursor (proBDNF) is expressed in the central nervous system (CNS) and the immune system. However, the role of proBDNF in the pathogenesis of multiple sclerosis (MS) is unknown. Peripheral blood and post-mortem brain and spinal cord specimens were obtained from multiple sclerosis patients to analyze proBDNF expression in peripheral lymphocytes and infiltrating immune cells in the lesion site.

Scutellarin ameliorates pulmonary fibrosis through inhibiting NF-κB/NLRP3-mediated epithelial-mesenchymal transition and inflammation.

Idiopathic pulmonary fibrosis (IPF) is featured with inflammation and extensive lung remodeling caused by overloaded deposition of extracellular matrix. Scutellarin is the major effective ingredient of breviscapine and its anti-inflammation efficacy has been reported before. Nevertheless, the impact of scutellarin on IPF and the downstream molecular mechanism remain unclear.

Liproxstatin-1 is an effective inhibitor of oligodendrocyte ferroptosis induced by inhibition of glutathione peroxidase 4.

Our previous studies showed that ferroptosis plays an important role in the acute and subacute stages of spinal cord injury. High intracellular iron levels and low glutathione levels make oligodendrocytes vulnerable to cell death after central nervous system trauma. In this study, we established an oligodendrocyte (OLN-93 cell line) model of ferroptosis induced by RSL-3, an inhibitor of glutathione peroxidase 4 (GPX4).

Guideline for diagnosis and treatment of spine trauma in the epidemic of COVID-19.

Outbreak of COVID-19 is ongoing all over the world. Spine trauma is one of the most common types of trauma and will probably be encountered during the fight against COVID-19 and resumption of work and production. Patients with unstable spine fractures or continuous deterioration of neurological function require emergency surgery.

Neuroprotective effect of deferoxamine on erastininduced ferroptosis in primary cortical neurons.

The iron chelator deferoxamine has been shown to inhibit ferroptosis in spinal cord injury. However, it is unclear whether deferoxamine directly protects neurons from ferroptotic cell death. By comparing the survival rate and morphology of primary neurons and SH-SY5Y cells exposed to erastin, it was found that these cell types respond differentially to the duration and concentration of erastin treatment.

Risk Factors of Deterioration in Quality of Life Scores in Thyroid Cancer Patients After Thyroidectomy.

Objective: Despite the expectation of normal life expectancy for thyroid cancer, there are concerns about the decreased quality of life (QoL). The present study investigated the potential risk factors of deterioration in QoL scores in thyroid cancer patients after thyroidectomy.

Materials And Methods: A total of 286 patients who were diagnosed with thyroid cancer after thyroidectomy were involved in this prospective, single-center, observational study from November 2018 to June 2019.

Bioinformatic identification of key candidate genes and pathways in axon regeneration after spinal cord injury in zebrafish.

Zebrafish and human genomes are highly homologous; however, despite this genomic similarity, adult zebrafish can achieve neuronal proliferation, regeneration and functional restoration within 6-8 weeks after spinal cord injury, whereas humans cannot. To analyze differentially expressed zebrafish genes between axon-regenerated neurons and axon-non-regenerated neurons after spinal cord injury, and to explore the key genes and pathways of axonal regeneration after spinal cord injury, microarray GSE56842 was analyzed using the online tool, GEO2R, in the Gene Expression Omnibus database. Gene ontology and protein-protein interaction networks were used to analyze the identified differentially expressed genes.

MicroRNA changes of bone marrow-derived mesenchymal stem cells differentiated into neuronal-like cells by Schwann cell-conditioned medium.

Bone marrow-derived mesenchymal stem cells differentiate into neurons under the induction of Schwann cells. However, key microRNAs and related pathways for differentiation remain unclear. This study screened and identified differentially expressed microRNAs in bone marrow-derived mesenchymal stem cells induced by Schwann cell-conditioned medium, and explored targets and related pathways involved in their differentiation into neuronal-like cells.

Construction of a Genomic Bacterial Artificial Chromosome (BAC) Library for the Prawn Macrobrachium rosenbergii and Initial Analysis of ZW Chromosome-Derived BAC Inserts.

Knowledge on sex determination has proven valuable for commercial production of the prawn Macrobrachium rosenbergii due to sex dimorphism of the male and female individuals. Previous studies indicated that prawn sex is determined by a ZW-ZZ chromosomal system, but no genomic information is available for the sex chromosome. Herein, we constructed a genomic bacterial artificial chromosome (BAC) library and identified the ZW-derived BAC clones for initial analysis of the sex chromosomal DNA sequence.

Deferoxamine promotes recovery of traumatic spinal cord injury by inhibiting ferroptosis.

Ferroptosis is an iron-dependent novel cell death pathway. Deferoxamine, a ferroptosis inhibitor, has been reported to promote spinal cord injury repair. It has yet to be clarified whether ferroptosis inhibition represents the mechanism of action of Deferoxamine on spinal cord injury recovery.

Abnormal DNA Methylation in Thoracic Spinal Cord Tissue Following Transection Injury.

BACKGROUND Spinal cord injury (SCI) is a serious disease with high disability and mortality rates, with no effective therapeutic strategies available. In SCI, abnormal DNA methylation is considered to be associated with axonal regeneration and cell proliferation. However, the roles of key genes in potential molecular mechanisms of SCI are not clear.
