Functional characterization and epigenetic regulation of Tcf3a and Tcf3b during IgM B cell activation in large yellow croaker (Larimichthys crocea).

The transcription factor Tcf3 is a key regulator during mammalian B cell development and activation, which is highly expressed in precursor B cells, downregulated in mature B cells, and re-expressed upon B cell activation. Despite the extensive studies in mammals, its role in teleost B cells remains poorly characterized. Here, using the economically important marine teleost large yellow croaker (Larimichthys crocea) as a model, we identified two Tcf3 homologs (LcTcf3a and LcTcf3b) and found that both genes were upregulated during B cell activation.

Transcriptomic analysis reveals the role of MAPK signaling pathway in IgM B cells against Pseudomonas plecoglossicida infection in large yellow croaker (Larimichthys crocea).

The large yellow croaker (Larimichthys crocea), an economically important marine fish in China, often suffers serious losses due to visceral white nodule disease caused by Pseudomonas plecoglossicida infection. IgM B cells play critical roles in the defense against bacterial infection, yet their immune response and underlying mechanisms against the P. plecoglossicida infection in large yellow croaker remain poorly characterized.

Identification and annotation of the T cell receptor beta (TCRβ) locus in large yellow croaker (Larimichthys crocea).

The T cell receptor (TCR) plays a crucial role in antigen recognition and signal transduction during T cell immunity. While the TCR locus has been well characterized in mammals, its knowledge in teleosts remains limited. In this study, we identified the TCRβ locus in large yellow croaker (Larimichthys crocea), an important mariculture species in China, and found 31 V, 2 D, 13 J, and 2 C gene segments.

Landscape of targeted therapies for lung squamous cell carcinoma.

Lung cancer, a common type of malignant neoplasm, has seen significant advancements in the treatment of lung adenocarcinoma (LUAD). However, the management of lung squamous cell carcinoma (LSCC) continues to pose challenges. Traditional treatment methods for LSCC encompass surgical resection, chemotherapy, and radiotherapy.

Molecular characterization of the IgH locus and V(D)J recombination in large yellow croaker (Larimichthys crocea).

V(D)J recombination is crucial for generating a diverse repertoire of immunoglobulins. Although the V(D)J recombination process has been well characterized in mammals, this process remains largely unexplored in teleosts. In this study, we comprehensively analyzed the IgH locus of a marine fish species large yellow croaker (Larimichthys crocea), and identified 28 V, 19 D, and 8 J gene segments, following a pattern of V-Dζ-Jζ-Cζ-Dμ-Jμ-Cμ1-Cμ2.

DNA methylation regulates B cell activation via repressing Pax5 expression in teleost.

In mammals, the transcription factor Pax5 is a key regulator of B cell development and maturation and specifically expressed in naive/mature B cells but repressed upon B cell activation. Despite the long-standing proposal that Pax5 repression is essential for proper B cell activation, the underlying mechanisms remain largely elusive. In this study, we used a teleost model to elucidate the mechanisms governing Pax5 repression during B cell activation.

Does acupuncture improve the metabolic outcomes of obese/overweight children and adolescents?: A systematic review and meta-analysis.

Background: Although increasing evidence has revealed the efficacy of acupuncture in obesity/overweight, actual improvement in metabolism in children and adolescents is unclear. Therefore, we conducted a meta-analysis to evaluate this correlation.

Methods: A comprehensive search was conducted using multiple databases, including Medline, Cochrane, Embase, Web of Science, Chinese Biomedical Literature Database, China National Knowledge Infrastructure, Chinese Scientific Journal Database, and Wan-fang Data, to identify relevant randomized controlled trials published before February 1, 2023.

An Array Magnetic Coupling Piezoelectric and Electromagnetic Energy Harvester for Rotary Excitation.

The energy of rotating machinery exists widely in the environment. It is of great significance to collect and utilize the energy of rotating machinery for sustainable development. In this paper, a novel piezoelectric and electromagnetic energy harvester, which is capable of generating electrical energy under rotary excitation, is proposed based on array magnetic coupling.

Inhibition of mGluR5/PI3K-AKT Pathway Alleviates Alzheimer's Disease-Like Pathology Through the Activation of Autophagy in 5XFAD Mice.

Background: The metabotropic glutamate receptor 5 (mGluR5) is widely expressed in postsynaptic neurons and plays a vital role in the synaptic plasticity of the central nervous system. mGluR5 is a coreceptor for amyloid-β (Aβ) oligomer, and downregulation or pharmacological blockade of mGluR5 presents the therapeutic potential of Alzheimer's disease (AD). However, the abnormality of mGluR5 in the pathogenesis of AD and its mechanism of pathology is not clear.
