Tongue squamous cell carcinoma (TSCC) is a common oral malignancy prone to metastasis, whose underlying mechanism remains obscure. Here, we report the oncogenic roles of protein arginine methyltransferase 5 (PRMT5) in TSCC via inhibiting transcription factor ΔNp63α. We found that PRMT5 physically interacts with ΔNp63α, resulting in impairment of ΔNp63α-mediated transcriptional regulation.

Mounting documents indicate the complicated roles of this kinase in various malignancies. Here, we roundly overview the regulation of CDK1 in malignancies, and find that CDK1 is widely upregulated in diverse cancers at either expression or enzymatic activity levels.

However, its global regulatory landscape under pathogenic stress remains largely unexplored in non-model invertebrates. In this study, we conducted an in-depth analysis of alternative splicing responses in Apostichopus japonicus under Vibrio splendidus infection by integrating long-read transcriptomic sequencing with the SUPPA2 framework.

In recent years, lncRNAs (long non-coding RNAs) as well as m6A (N6-methyladenosine) modification have been found to play important roles during pathogens infection induced innate immune response. However, the relationship between the lncRNAs and m6A modification remains unclear. Here, we show that the lncRNA (lnc-28509) from sea cucumber Apostichopus japonicus was significantly induced in response to Vibrio splendidus infection.

TAp63α is a member of the p53 protein family that is generally tumor suppressive in various other p53-mutant or p53-deficient cancers. Here, we found that TAp63α inhibited cell proliferation, epithelial-mesenchymal transition (EMT), and migration in several p53-mutant PDAC cell lines.

Research indicates that the type VI secretion system (T6SS) is closely associated with the pathogenicity of bacteria. However, it remains unclear whether T6SS protein regulates coelomocyte inflammation during Vibrio splendidus infection and what the underlying molecular mechanisms are.

Objectives: To compare the impact-sliding wear properties of CAD/CAM polyetheretherketone (PEEK) materials and resin ceramics with dental enamel, and to investigate the corresponding wear mechanisms.
Methods: Six CAD/CAM polymer materials were assessed in comparison with human tooth enamel. Hardness, modulus and roughness values of each group were measured, prior to wear testing in a chewing simulator (ball-on-disc design, 49 N).
In vertebrates, the single immunoglobulin (Ig) interleukin-1 receptor-related molecule, SIGIRR, plays a role in controlling inflammatory responses. Its invertebrate homologous double Ig interleukin-1 receptor-related molecule, DIGIRR, is little known. We report here the cloning of a novel DIGIRR homologue in Apostichopus japonicus, named AjDIGIRR, using rapid amplification of cDNA ends (RACE).

Guanylate-binding proteins (GBPs) are interferon-induced innate immune effector molecules belonging to the GTPase superfamily and are crucial components of cell-autonomous immunity. To date, most research on GBPs has focused on mammals, with limited studies in marine invertebrates. In this study, we identified three GBP genes from the sea cucumber Apostichopus japonicus, designated as AjGBP1, AjGBP2, and AjGBP3.

Herein, the functions of theromacin from the razor clam Sinonovacula constricta (ScTM) were identified. Multiple sequence alignment revealed that the structure of ScTM was similar to that of a theromacin homolog with a signal peptide and conserved Macin domain.

Melatonin (MT), synthesized from tryptophan, modulates reproduction through its interaction with melatonin receptors (MTNRs). While its functions in vertebrates are well established, the MT system remains poorly understood in echinoderms. To elucidate MT synthesis regulation, we examined AjAsmt, a pivotal enzyme in MT biosynthesis, to determine its tissue-specific distribution in Apostichopus japonicus.

Lytic cell death including necroptosis and pyroptosis is induced by mixed lineage kinase domain-like protein (MLKL) phosphorylation and inflammatory caspase specific cleavage Gasdermins in higher mammals, respectively. In this study, we identified a novel MLKL homolog containing a tetrapeptide recognition motif (14-LVAD-17) of inflammatory caspase from Apostichopus japonicus,which was absent of Gasdermins member by genome screening. Functional analysis revealed that AjMLKL was involved in the regulation of Vibrio splendidus AJ01 infection induced lytic coelomocyte death in a cleavage-dependent manner, but not through RIPK3-dependent phosphorylation as mammals.

In our previous study, the eukaryotic factor STPKLRR was identified from the intracellular pathogen Vibrio splendidus AJ01 and shown to facilitate promote AJ01 internalization by mediating actin-dependent coelomocytes phagocytosis. However, the molecular mechanisms underlying AJ01'escaped from the phagosome remained largely unclear.

The Fibrinogen-related protein (FREP) gene family is a cornerstone of immune defense in metazoans, yet its evolution and functional specialization in invertebrates, particularly sea cucumbers, remain underexplored. By analyzing genomic data from 1004 species, this study reveals a significant and lineage-specific expansion of FREP genes in sea cucumbers. These genes are categorized into single-domain FREPs (sFREPs) and multi-domain FREPs (mFREPs), with the latter containing unique TIL domains associated with immune defense.

Autophagy is essential for maintaining material balance and energy circulation and plays a critical role as a regulatory mechanism in tissue regeneration. However, current studies primarily describe this phenotype, with limited exploration of its molecular mechanisms. In this study, we provided the first evidence that autophagy is required for intestinal regeneration in Apostichopus japonicus and identified a previously unrecognized regulatory mechanism involved in this process.

Esophageal squamous cell carcinoma (ESCC) is one of the most aggressive cancers and is highly prevalent in China, exhibiting resistance to current treatments. ΔNP63α, the main isoform of p63, is frequently amplified in ESCC and contributes to therapeutic resistance, although the molecular mechanisms remain unknown. Here, we report that ΔNP63α is highly expressed in ESCC and is associated with radioresistance by reducing ROS level.

As a class rich in active substances with significant nutritional and medicinal value, echinoderms face threats from marine pathogens, including bacteria, viruses, fungi, protozoa, and parasites, which have caused substantial economic losses in echinoderm aquaculture. Echinoderms counteract pathogen invasion through innate immunity and programmed cell death, in particular, with apoptosis being essential for eliminating infected or damaged cells and maintaining homeostasis in many echinoderm cell types.
