Tachykinin signaling in the right parabrachial nucleus mediates early-phase neuropathic pain development.

The lateral parabrachial nucleus (PBN) is critically involved in neuropathic pain modulation. However, the cellular and molecular mechanisms underlying this process remain largely unknown. Here, we report that in mice, the right-sided, but not the left-sided, PBN plays an essential role in the development of hyperalgesia following nerve injury, irrespective of the injury side.

Development of a competitive ELISA based on the LSDV A33 antigen.

Goatpoxvirus (GTPV), sheeppoxvius (SPPV), and the Lumpy skin disease virus (LSDV) is a Capripoxvirus belonging to the family poxviridae. They can cause significant economic losses in countries where this disease are endemic. However, effective and convenient diagnostic tools against sera antibody are not readily available until now.

Transcriptome analysis of long non-coding RNA and mRNA Profiles in VSV-infected BHK-21 Cells.

Background: Vesicular stomatitis virus (VSV) is a typical non-segmented negative-sense RNA virus of the genus Vesiculovirus in the family Rhabdoviridae. VSV can infect a wide range of animals, including humans, with oral blister epithelial lesions. VSV is an excellent model virus with a wide range of applications as a molecular tool, a vaccine vector, and an oncolytic vector.

Whole-brain in vivo base editing reverses behavioral changes in Mef2c-mutant mice.

Whole-brain genome editing to correct single-base mutations and reduce or reverse behavioral changes in animal models of autism spectrum disorder (ASD) has not yet been achieved. We developed an apolipoprotein B messenger RNA-editing enzyme, catalytic polypeptide-embedded cytosine base editor (AeCBE) system for converting C·G to T·A base pairs. We demonstrate its effectiveness by targeting AeCBE to an ASD-associated mutation of the MEF2C gene (c.

A Strainer-Based Platform for the Collection and Immunolabeling of Mouse Intestinal Organoids.

Intestinal organoids have emerged as powerful model systems for studying the complex structure and function of the intestine. However, there is a lack of widely applicable methods for the collection, labeling, and imaging of intestinal organoids. In this study, we developed a novel method for loading and labeling intestinal organoids, a method that efficiently collects the organoids and facilitates imaging of their three-dimensional (3D) structure.

Taok1 haploinsufficiency leads to autistic-like behaviors in mice via the dorsal raphe nucleus.

Strong evidence from human genetic studies associates the thousand and one amino acid kinase 1 (TAOK1) gene with autism spectrum disorder (ASD). In this work, we discovered a de novo frameshifting mutation in TAOK1 within a Chinese ASD cohort. We found that Taok1 haploinsufficiency induces autistic-like behaviors in mice.

Lumpy Skin Disease Virus Infection Activates Autophagy and Endoplasmic Reticulum Stress-Related Cell Apoptosis in Primary Bovine Embryonic Fibroblast Cells.

Poxviruses have been associated with humans for centuries. From smallpox to mpox to lumpy skin disease virus (LSDV), members of the poxvirus family have continued to threaten the lives of humans and domestic animals. A complete understanding of poxvirus-mediated cellular processes will aid in the response to challenges from the viruses.

Emerging evidence for poxvirus-mediated unfolded protein response: Lumpy skin disease virus maintains self-replication by activating PERK and IRE1 signaling.

The monkeypox epidemic has attracted global attention to poxviruses. The cytoplasmic replication of poxviruses requires extensive protein synthesis, challenging the capacity of the endoplasmic reticulum (ER). However, the role of the ER in the life cycle of poxviruses is unclear.

Imbalance hepatic metabolism homeostasis in the F1 generation of endometrial conditional knockout female mice.

Numerous studies have suggested the possibility of explaining the etiology of metabolic syndrome through DNA methylation. DNA methyltransferase 3B (DNMT3B) plays an important role in DNA methylation. There was an alteration in maternal (F0) endometrial function, which might lead to growth and developmental disorder in offspring (F1).

Impairment of endometrial decidual reaction in early pregnant mice fed with high fat diet.

Objective: To investigate the effect of obesity induced by high fat diet on decidual reaction of endometrium in mice, and the effect of high fat treatment on decidual reaction of endometrial stromal cells.

Methods: Twelve 4-week-old healthy C57BL/6J female mice were randomly divided into high fat diet group and control group with 6 mice in each group. They were fed with high fat diet (22 kJ/g) or normal diet (16 kJ/g) for 12 weeks, respectively.

CircPOLR2A Promotes Proliferation and Impedes Apoptosis of Glioblastoma Multiforme Cells by Up-regulating POU3F2 to Facilitate SOX9 Transcription.

Glioblastoma multiforme (GBM) is the most common cancer in nervous system around the world. Little advancement has been achieved in promoting prognosis of GBM patients. Circular RNAs (circRNAs) are suggested as crucial effectors in modulating GBM development.

Uterine deficiency of Dnmt3b impairs decidualization and causes consequent embryo implantation defects.

Uterine deficiency of Dnmt3b impairs decidualization and consequent embryo implantation defects. Recent advances in molecular technologies have allowed the unprecedented mapping of epigenetic modifications during embryo implantation. DNA methyltransferase 3a (DNMT3A) and DNMT3B are responsible for establishing DNA methylation patterns produced through their de novo-type DNA methylation activity in implantation stage embryos and during germ cell differentiation.

The Unique Glycosylation at Position 986 on the E2 Glycoprotein of Classical Swine Fever Virus Is Responsible for Viral Attenuation and Protection against Lethal Challenge.

Classical swine fever (CSF) is an economically important disease of pigs caused by classical swine fever virus (CSFV). The live attenuated vaccine C-strain (also called HCLV strain) against CSF was produced by multiple passages of a highly virulent strain in rabbits. However, the molecular determinants for its attenuation and protection remain unclear.

Exposure to ethylparaben and propylparaben interfere with embryo implantation by compromising endometrial decidualization in early pregnant mice.

Ethylparaben (EtP) and propylparaben (PrP) are common preservatives and well-known endocrine-disrupting chemicals. Studies have demonstrated that they can reduce female fertility, but the underlying mechanism, especially that on embryo implantation, is still poorly understood. Endometrial decidualization is a critical event for embryo implantation.

Host defense peptide LL-37 is involved in the regulation of cell proliferation and production of pro-inflammatory cytokines in hepatocellular carcinoma cells.

Recent studies on the roles and mechanisms of LL-37 have demonstrated that LL-37 can either serve as a tumor promoter or a tumor suppressor in different cancers. The expression and function of LL-37 in hepatocellular carcinoma (HCC), however, remain unclear. In the present study, we confirmed the down-regulation of LL-37 in HCC tissues and the synthetic LL-37 peptide reduced the viability of HCC cells in a dose-dependent manner.

Stent placement combined with intraluminal radiofrequency ablation and hepatic arterial infusion chemotherapy for advanced biliary tract cancers with biliary obstruction: a multicentre, retrospective, controlled study.

Objective: To evaluate the efficacy and safety of stent placement combined with intraluminal radiofrequency ablation (intra-RFA) and hepatic arterial infusion chemotherapy (HAIC) for patients with advanced biliary tract cancers (Ad-BTCs) and biliary obstruction (BO).

Methods: We retrospectively reviewed data for patients with Ad-BTCs and BO who underwent stent placement with or without intra-RFA and HAIC in three centres between November 2013 and November 2018. The stent patency time (SPT), overall survival (OS), and adverse events (AEs) were analysed.

Identification and screening of host proteins interacting with ORFV-ORF047 protein.

Background: Orf virus (ORFV) is a member of the genus Parapoxvirus and family Poxviridae. The virus has a worldwide distribution and infects sheep, goats, humans, and wild animals. However, due to the complex structure of the poxvirus, the underlying mechanism of the entry and infection by ORFV remains largely unknown.

[Exposure level of advanced glycation end products in the diet of Shenzhen residents in 2017].

Objective: To investigate the dietary exposure level of advanced glycation end products(AGEs) in the diet of Shenzhen residents.

P108 and T109 on E2 Glycoprotein Domain I Are Critical for the Adaptation of Classical Swine Fever Virus to Rabbits but Not for Virulence in Pigs.

The classical swine fever virus (CSFV) live attenuated vaccine C-strain is adaptive to rabbits and attenuated in pigs, in contrast with the highly virulent CSFV Shimen strain. Previously, we demonstrated that P108 and T109 on the E2 glycoprotein (E2) in domain I (E2) rather than R132, S133, and D191 in domain II (E2) determine C-strain's adaptation to rabbits (ATR) (Y. Li, L.

Microbial Community, Newly Sequestered Soil Organic Carbon, and δN Variations Driven by Tree Roots.

Rhizosphere microbes in forests are key elements of the carbon sequestration of terrestrial ecosystems. To date, little is known about how the diversity and species interactions of the active rhizomicrobial community change during soil carbon sequestration and what interactions drive these changes. In this study, we used a combination of DNA and stable isotope method to explore correlations between the composition of microbial communities, N transformation, and the sequestration of carbon in soils around and roots in North China.

Differential responses of the acidobacterial community in the topsoil and subsoil to fire disturbance in stands.

is found to be dominant and abundant in forest soil, and performs specific ecological functions (such as cellulose decomposition and photosynthetic capacity, etc.). However, relative limited is known about its changing patterns after a fire interruption.

Overexpression of Smac by an Armed Vesicular Stomatitis Virus Overcomes Tumor Resistance.

Despite reports of successful clinical cases, many tumors appear to resist infection by oncolytic viruses (OVs). To circumvent this problem, an armed vesicular stomatitis virus was constructed by inserting a transgene to express Smac/DIABLO during virus infection (VSV-S). Endogenous Smac in HeLa cells was diminished during wtVSV infection, whereas the Smac level was enhanced during VSV-S infection.
