AIM2 promotes excitatory glutamate receptor expression by inhibiting STING and contributes to bone cancer pain in male mice.

Bone cancer pain (BCP) is a common clinical problem in cancer patients. The plasticity of excitatory neurons within the spinal dorsal horn plays a significant role in the development of BCP. This study explored the roles of absent in melanoma 2 (AIM2) and stimulator of interferon gene (STING) in BCP using male C57BL/6J mice.

Lysophosphatidylcholine induced by fat transplantation regulates hyperalgesia by affecting the dysfunction of ACC perineuronal nets.

The pathogenesis of hyperalgesia is complex and can lead to poor clinical treatment. Our study revealed that epididymal white adipose tissue (eWAT) from spared nerve injury (SNI) mice is involved in the occurrence of hyperalgesia after adipose tissue transplantation. We also showed that lysophosphatidylcholine (LPC) is enriched in the eWAT of SNI mice using non-targeted metabolomic analysis and verified that the levels of LPC in plasma and the anterior cingulate cortex (ACC) region increased following eWAT transplantation.

Dock4 contributes to neuropathic pain by regulating spinal synaptic plasticity in mice.

Introduction: Neuropathic pain (NP) conditions arising from injuries to the nervous system due to trauma, disease, or neurotoxins are chronic, severe, debilitating, and exceedingly difficult to treat. However, the mechanisms of NP are not yet clear. Here we explored the role of Dock4, an atypical Rac1 GEF, in the development of NP.

The global burden, trends, and inequalities of individuals with developmental and intellectual disabilities attributable to iodine deficiency from 1990 to 2019 and its prediction up to 2030.

Objective: The objective of this study was to assess the global burden of disease for developmental and intellectual disabilities caused by iodine deficiency from 1990 to 2019.

Methods: Using data from the global burden of disease (GBD) 2019, we conducted a cross-country inequity analysis to examine the worldwide burden of developmental and intellectual disabilities caused by the issue of iodine deficiency from 1990 to 2019. Absolute and relative inequality were assessed by the slope index of inequality and the concentration index, respectively.

Thrombospondin 4, a mediator and candidate indicator of pain.

Pain is the most common symptom for which patients seek medical attention. Existing treatments for pain control are largely ineffective due to the lack of an accurate way to objectively measure pain intensity and a poor understanding of the etiology of pain. Thrombospondin 4(TSP4), a member of the thrombospondin gene family, is expressed in neurons and astrocytes and induces pain by interacting with the calcium channel alpha-2-delta-1 subunit (Cavα2δ1).

Differential epitranscriptome and proteome modulation in the brain of neonatal mice exposed to isoflurane or sevoflurane.

Background: Repeated neonatal exposure to anesthetics may disturb neurodevelopment and cause neuropsychological disorders. The m6A modification participates in the gene regulation of neurodevelopment in mouse fetuses exposed to anesthetics. This study aims to explore the underlying molecular mechanisms of neurotoxicity after early-life anesthesia exposure.

Schnurri-2 Promotes the Expression of Excitatory Glutamate Receptors and Contributes to Neuropathic Pain.

Neuropathic pain is a type of chronic pain with complex mechanisms, and current treatments have shown limited success in treating patients suffering from chronic pain. Accumulating evidence has shown that the pathogenesis of neuropathic pain is mediated by the plasticity of excitatory neurons in the dorsal horn of the spinal cord, which provides insights into the treatment of hyperalgesia. In this study, we found that Schnurri-2 (Shn2) was significantly upregulated in the L4-L6 segments of the spinal cord of C57 mice with spared nerve injury, which was accompanied by an increase in GluN2D subunit and glutamate receptor subunit 1 (GluR1) levels.

P-Rex2 mediation of synaptic plasticity contributes to bone cancer pain.

Bone cancer pain (BCP) seriously affects the quality of life; however, due to its complex mechanism, the clinical treatment was unsatisfactory. Recent studies have showed several Rac-specific guanine nucleotide exchange factors (GEFs) that affect development and structure of neuronal processes play a vital role in the regulation of chronic pain. P-Rex2 is one of GEFs that regulate spine density, and the present study was performed to examine the effect of P-Rex2 on the development of BCP.

NWD1 facilitates synaptic transmission and contributes to neuropathic pain.

Neuropathic pain is the most common symptom for which patients seek medical attention. Existing treatments to control pain are largely ineffective because of poor understanding the underlying mechanisms. Synaptic plasticity is fundamental to the spinal sensitivity of neuropathic pain.

CXCL12 promotes spinal nerve regeneration and functional recovery after spinal cord injury.

Spinal cord injury (SCI) leads to permanent loss of motor and sensory function due to the complex mechanisms of the external microenvironment and internal neurobiochemistry that restrict neuronal plasticity and axonal regeneration. Chemokine CXCL12 was verified in regulating the development of central nervous system (CNS) and repairing of CNS disease. In the present study, CXCL12 was downregulated in the spinal cord after SCI.

Exercise or sport activities for patients with cancer: A protocol for overview of systematic reviews and meta-analyses.

Objective: We plan to review all published systematic reviews (SRs) and meta-analyses (MAs) of exercise or sport activities for patients with cancer. The aim of this study is to combine and reanalyze related data and to provide more comprehensive and higher-level evidence.

Methods: We plan to search four English databases and four Chinese databases from inception to June 2019.

MiRNA-574-3p inhibits cell progression by directly targeting CCND2 in colorectal cancer.

Colorectal cancer (CRC) remains the candidate for one of the typical types of malignant tumors of in gastrointestinal tract all around the world, which leads to tremendous death and ranks as the top leading death of cancer. Recently, microRNAs have emerged as double-edged sword in numerous cancers. This investigation aims to discuss the regulative role of microRNA-574-3p (miR-574-3p), elucidating its molecular mechanism and clinical significance in CRC.

Association between rs2569190 C>T polymorphism and ischemic stroke susceptibility: a meta-analysis based on 5,277 subjects.

Introduction: Previous epidemiological studies have suggested that rs2569190 C>T polymorphism plays an important role in ischemic stroke (IS) risk, but the results were inconsistent. Therefore, we conducted a meta-analysis to determine the association between rs2569190 C>T polymorphism and IS susceptibility.

Methods: Online databases were searched from inception up to July 1, 2018, for studies concerning rs2569190 C>T polymorphism and its association with IS susceptibility.
