METTL3 modulates bone Cancer pain via mA-dependent JAK2/STAT3 activation in spinal astrocytes.

N6-methyladenosine (mA) is primarily associated with extensive changes in epigenetic regulation in eukaryotic organisms, particularly facilitated by the Methyltransferase-like 3 (METTL3) enzyme in cancer and inflammatory pain. However, the pathways through which METTL3 mediates these conditions remain largely unknown. This study elucidates the pathways by which mA methylation of JAK2 mRNA by METTL3 occurs within astrocytes in the spinal cord, thereby facilitating continuous JAK2 mRNA translation.

Grey matter volume differences in pediatric obsessive-compulsive disorder: a meta-analysis of voxel-based morphometry studies.

Background: Obsessive-compulsive disorder (OCD) is one of the most commonly seen mental disorders onset from childhood. The neural mechanisms underlying OCD development and maintenance remain poorly understood.

CRISPR/Cas12a and recombinase polymerase amplification-based rapid on-site nucleic acid detection of duck circovirus.

Background: Duck circovirus (DuCV) infections commonly induce immunosuppression and secondary infections in ducks, resulting in significant economic losses in the duck breeding industry. Currently, effective vaccines and treatments for DuCV have been lacking. Therefore, rapid, specific, and sensitive detection methods are crucial for preventing and controlling DuCV.

Development of the first officially licensed live attenuated duck hepatitis A virus type 3 vaccine strain HB80 in China and its protective efficacy against DHAV-3 infection in ducks.

Duck hepatitis A virus type 3 (DHAV-3) is an infectious virus that is highly fatal to ducklings and causes significant economic losses in the duck industry worldwide. Biosecurity and vaccination are required to control the pathogen. In the present study, we attenuated a lowly pathogenic DHAV-3 clinical isolate, named as HB, by serial passaging in duck embryos, and followed by several adaptive proliferations in specific-pathogen-free (SPF) chicken embryos.

An electrochemical aptasensor for highly sensitive detection of CEA based on exonuclease III and hybrid chain reaction dual signal amplification.

At present, carcinoembryonic antigen (CEA) is considered a broad-spectrum cancer biomarker, and its accurate analysis in clinical samples can assist early cancer diagnosis and treatment. Herein, a novel electrochemical aptasensor has been proposed for CEA detection based on exonuclease III and hybrid chain reaction. The target CEA specifically binds to the aptamer region in hairpin probe 1 (defined as H1) by strong attraction, which leads the rest of the H1 triggering catalytic hairpin assembly to form a high quantity of H1 and hairpin probe 2 (defined as H2) double chain complex (denoted as H1@H2).

Differential metabolism-associated gene expression of duck pancreatic cells in response to two strains of duck hepatitis A virus type 1.

Both Muscovy duck parvovirus (MDPV) and goose parvovirus (GPV) can cause high mortality and morbidity in Muscovy ducklings. MDPVs and GPVs share high nucleotide identity, which can cause errors during differential diagnosis. In this study, the NS genes of both MDPVs and GPVs were chosen for the design of specific primers after genetic comparison.

This study reports the findings of a high-resolution melting (HRM) curve analysis combined with PCR technique (PCR-HRM) to differentiate between Muscovy duck parvovirus (MDPV) and goose parvovirus (GPV). A degenerate primer set was designed based on the VP3 gene of MDPV and GPV. The PCR HRM assay was able to discriminate between MDPVs and GPVs by differences in melting curve shapes and melting temperatures.

Genomic and pathogenic analysis of a Muscovy duck parvovirus strain causing short beak and dwarfism syndrome without tongue protrusion.

In 2008, clinical cases of short beak and dwarfism syndrome (SBDS) caused by Muscovy duck parvovirus (MDPV) infection were found in mule duck and Taiwan white duck farms in Fujian, China. A MDPV LH strain causing duck SBDS without tongue protrusion was isolated in this study. Phylogenetic analysis show that the MDPV LH strain was clustered together with other MDPV strains, but divergent from GPV isolates.

Prediction of Toxin Genes from Chinese Yellow Catfish Based on Transcriptomic and Proteomic Sequencing.

Fish venom remains a virtually untapped resource. There are so few fish toxin sequences for reference, which increases the difficulty to study toxins from venomous fish and to develop efficient and fast methods to dig out toxin genes or proteins. Here, we utilized Chinese yellow catfish (Pelteobagrus fulvidraco) as our research object, since it is a representative species in Siluriformes with its venom glands embedded in the pectoral and dorsal fins.

Comparative analysis of transcriptional profiles of retinoic-acid-induced gene I-like receptors and interferons in seven tissues from ducks infected with avian Tembusu virus.

Avian Tembusu virus (ATV), an emerging virus that mainly infects laying and breeding ducks in China, has caused severe economic loss in duck industry. However, there have been no reports about host innate immune responses during ATV infection and its correlation with clinical signs or pathology. To identify the roles of these immune factors in the innate host response to ATV infection, quantitative real-time PCR (qPCR) was used to analyze the transcriptional profiles on the genes encoding two retinoic-acid-induced gene I (RIG-I)-like receptors (RLRs) and two interferons (INF-α and INF-γ) in seven tissues of an ATV-infected shelduck.
