Choline dehydrogenase interacts with SQSTM1 to activate mitophagy and promote coelomocyte survival in following infection.

Previous studies have shown that infection causes mitochondrial damage in coelomocytes, leading to the production of excessive reactive oxygen species (ROS) and irreversible apoptotic cell death. Emerging evidence suggests that mitochondrial autophagy (mitophagy) is the most effective method for eliminating damaged mitochondria and ROS, with choline dehydrogenase (CHDH) identified as a novel mitophagy receptor that can recognize non-ubiquitin damage signals and microtubule-associated protein 1 light chain 3 (LC3) in vertebrates. However, the functional role of CHDH in invertebrates is largely unknown.

A multi-model fusion algorithm as a real-time quality control tool for small shift detection.

Background: Patient-based real-time quality control (PBRTQC), a complement to traditional QC, may eliminate matrix effect from QC materials, realize real-time monitoring as well as cut costs. However, the accuracy of PBRTQC has not been satisfactory as physicians expect till now. Our aim is to set up a artificial intelligence-based QC for small error detection in real laboratory settings.

Identification of global alternative splicing and sex-specific splicing via comparative transcriptome analysis of gonads of Chinese tongue sole ( ).

Chinese tongue sole ( ) is an economically important marine fish species with a ZZ/ZW sex determination mechanism, which can be influenced by temperature. Alternative splicing (AS) is an important mechanism regulating the expression of genes related to sex determination and gonadal differentiation, but has rarely been reported in fish. In this study, to explore the molecular regulatory mechanisms of sex determination and gonadal differentiation, we combined isoform and RNA sequencing (Iso-Seq and RNA-Seq) to perform transcriptome profiling of male and female gonads in .

ROS-mediated BNIP3-dependent mitophagy promotes coelomocyte survival in in response to infection.

Organisms produce high levels of reactive oxygen species (ROS) to kill pathogens or act as signaling molecules to induce immune responses; however, excessive ROS can result in cell death. To maintain ROS balance and cell survival, mitophagy selectively eliminates damaged mitochondria via mitophagy receptors in vertebrates. In marine invertebrates, however, mitophagy and its functions remain largely unknown.

A highly accurate delta check method using deep learning for detection of sample mix-up in the clinical laboratory.

Objectives: Delta check (DC) is widely used for detecting sample mix-up. Owing to the inadequate error detection and high false-positive rate, the implementation of DC in real-world settings is labor-intensive and rarely capable of absolute detection of sample mix-ups. The aim of the study was to develop a highly accurate DC method based on designed deep learning to detect sample mix-up.

Long non-coding RNA MALAT1 enhances angiogenesis during bone regeneration by regulating the miR-494/SP1 axis.

Bone regeneration is a coordinated process involving connections between blood vessels and osteocytes. Angiogenesis and osteogenesis are tightly connected throughout the progression of bone regeneration. This study aimed to explore the underlying mechanism of metastasis-associated lung adenocarcinoma transcript 1 (MALAT1)-regulated angiogenesis during bone regeneration.

sp. nov., a phosphate-solubilizing bacterium isolated from a solar saltern.

A Gram-stain-negative, motile, rod-shaped, non-endospore-forming, aerobic and halophilic bacterium, designated strain YCWA18, was isolated from the sediment of Jimo-Daqiao saltern in China. This strain was able to grow at NaCl concentrations in the range 0.5-20 % (w/v) with optimum growth at 6 % (w/v) NaCl.

M1 Macrophage-Derived Exosomal MicroRNA-326 Suppresses Hepatocellular Carcinoma Cell Progression Via Mediating NF-κB Signaling Pathway.

Accumulating evidence has shown that microRNA (miR) derived from M1 macrophage-derived exosomes can regulate the progression of hepatocellular carcinoma (HCC). However, the effect of miR-326 derived from M1 macrophage-derived exosomes on HCC has not been reported. Therefore, the objective of the present study was to explore the mechanism of exosomal miR-326 from M1 macrophages in regulating HCC cell progression.

The NK-1R Antagonist Aprepitant Prevents LPS-Induced Oxidative Stress and Inflammation in RAW264.7 Macrophages.

Background: The macrophage is one of the most important types of immune cells that protect against harmful stimuli. Macrophage activation plays a pivotal role in the progression and development of various inflammatory diseases. The neurokinin 1 receptor (NK-1R) is a G protein-coupled receptor that plays an important role in inflammatory diseases.

Characterization of microRNAs by deep sequencing in red claw crayfish Cherax quadricarinatus haematopoietic tissue cells after white spot syndrome virus infection.

White spot syndrome virus (WSSV) is one of the most prevalent and widespread viruses in both shrimp and crayfish aquaculture. MicroRNAs (miRNAs) are crucial post-transcriptional regulators and play critical roles in cell differentiation and proliferation, apoptosis, signal transduction and immunity. In this study, miRNA expression profiles were identified via deep sequencing in red claw crayfish Cherax quadricarinatus haematopoietic tissue (Hpt) cell cultures infected with WSSV at both early (i.

White spot syndrome virus entry is dependent on multiple endocytic routes and strongly facilitated by Cq-GABARAP in a CME-dependent manner.

White spot syndrome virus (WSSV) is a lethal pathogen of shrimp and many other crustaceans, including crayfish. However, the molecular mechanism underlying its cellular entry remains elusive due to the lack of shrimp cell lines for viral propagation. Crayfish hematopoietic tissue (Hpt) cell culture was recently established as a good model for WSSV infection study.

miRNA-133 augments coelomocyte phagocytosis in bacteria-challenged Apostichopus japonicus via targeting the TLR component of IRAK-1 in vitro and in vivo.

In this study, we explored the potential roles of miRNA-133 in regulating TLR pathways in the sea cucumber Apostichopus japonicus. Target screening of RNA-Seq data successfully identified interleukin-1 receptor-associated kinase (AjIRAK-1) as a putative target of miR-133. This result was further validated by negative expression profiles in Vibrio splendidus-challenged coelomocytes and lipopolysaccharide (LPS)-exposed cell cultures.
