Summary: In this study, we used an integrative approach combining cytogenetic data and sequence-based phylogeny to investigate the mechanisms of karyotype differentiation in scorpions of the genus Gint. Our results revealed significant karyotype diversity and chromosome heterozygosity in Gint species. We also found that interspecific differences in chromosome counts corresponded with genetic divergence. Furthermore, the study indicated ongoing structural changes in the genome architecture of some Gint species.

Summary: The diversity and taxonomy of sea stars in the Southern Ocean need to be revised and explored further, as molecular results indicate recent diversification at the genus and species levels. This supports a scenario of invasion and exchange events between the Southern Ocean and adjacent regions, with clade diversification during periods of rapid environmental changes.

Summary: Physiological indices related to hypoxia adaptation mechanisms were measured in F-3 self-crossing population of blunt snout bream (Megalobrama amblycephala) female x topmouth culter (Culter alburnus) male hybrids. The results showed that the F-3 hybrids had higher hypoxia tolerance than blunt snout bream and could adapt to the low oxygen environment by changing the morphology and physiological and biochemical levels of gill tissue.

Summary: This study aimed to reconstruct the speciation process and phylogenetic dispersal of the endemic Korean freshwater fish species Coreoleuciscus. Through analysis of mitochondrial cytochrome c oxidate subunit I, the study found that the species originated from independent colonization in ancestral populations during the Late Plio-Pleistocene. Evidence was also provided for the species' origin in the Eastern Eurasian continent and subsequent dispersal into East Asia. The study highlighted the importance of genetic diversity in large drainage populations for the conservation and management of Coreoleuciscus.

Summary: This study examined the impact of ultrasound treatment on the quality of salted Culter alburnus fish. The findings revealed that higher ultrasound power led to increased degradation of muscle fibers and significant changes in myofibrillar protein conformation. The 300 W ultrasound treatment group exhibited higher thiobarbiturate reactive substance content and peroxidation value. There were notable differences among groups in terms of the 66 identified volatile compounds. The 200 W ultrasound group showed lower fishy substances, while the ultrasound groups had higher levels of umami taste-related amino peptides. Ultrasound treatment enriched the amino acid, carbohydrate, and fatty acyl metabolism products in the salted fish, which may ultimately influence the taste and flavor.

Summary: This study investigated the genetic differentiation and phylogeography of the Chondrosia reniformis sponge populations in Tunisia. The results showed that these populations may have experienced a bottleneck and rapid demographic expansion, leading to high genetic differentiation among different localities. The geographic origin played a significant role in the distribution of the sponge populations, with the Siculo-Tunisian Strait acting as a biogeographic barrier. The findings contribute to a better understanding of the population evolution and environmental adaptation of this sponge species.

Summary: Microplastics adsorb contaminants and can mitigate the toxic effects of certain pollutants on microorganisms, as demonstrated by combined-exposure assays showing that polyethylene microplastics can alleviate the toxicity of nano zinc oxide on marine microalgal growth. This interaction may be achieved through zinc oxide adsorption onto the polyethylene microplastic surface.

Summary: This study identified a novel TLR isoform called McTLRlike1 in the mollusk Mytilus coruscus. McTLR-like1 was highly expressed in immune-related tissues and its levels increased when challenged with V. alginolyticus. It was found that McTLR-like1 activated NF-kappa B and influenced the expression and phosphorylation of its subunit P65. Silencing McTLR-like1 led to downregulation of pro-inflammatory cytokines and increased resistance to V. alginolyticus challenge. McTLR-like1 also showed affinity with McMyD88a. These findings contribute to our understanding of TLR signaling in mollusks and provide insights into TLR evolution.

Summary: In this study, a proteomic data set was generated to investigate the physiological events involving death after spawning in S. japonica. Differential expression proteins (DEPs) were identified using a proteomic-based approach, and their functions were found to be mainly related to gene translation and signal transduction. The study also discovered aging-related DEPs in addition to those involved in signal transduction and energy metabolism. Overall, this study provides new insights into the phenomenon of death after spawning in S. japonica at the protein level.

Summary: Plastic pollution is a severe marine environmental issue. This study investigated the toxic effects of acute exposure to different sizes of plastic particles on mussels using various techniques. The results showed that mussels efficiently ingested nanoplastics and experienced a severe inflammatory response, while microplastics caused a slight inflammatory response. Biochemical analysis revealed up-regulation of biomarkers after plastic particle exposure. Nanoplastics induced more ROS production and higher T-AOC level than microplastics. Transcriptomic sequencing indicated that differentially expressed genes were mostly involved in stress and immune response pathways. Acute exposure to nanoplastics was found to be more toxic than microplastics. Microplastics exposure may impair olfactory function and cause neurotoxicity to mussels. These findings provide new insights into the ecotoxicological mechanisms of plastic particle exposure.

Summary: Due to global warming, the Mytilus coruscus attached in the intertidal zone face extreme and fluctuating temperature changes, leading to mass mortality. This study investigates the transcriptional response of M. coruscus at different temperatures and times by analyzing the intertidal zone temperature. In response to high temperatures, multiple signaling pathways in M. coruscus, including ribosome, endocytosis, endoplasmic reticulum stress, protein degradation, and lysosomes, interact to counter the adverse effects on protein homeostasis.

Summary: This study investigated the association between Mc-novel_miR_145 and IL-17 homolog (McIL-17-3) and their immunomodulatory effects in Mytilus coruscus. The results showed that McIL-17-3 was highly expressed in immune-associated tissues and responded to bacterial challenges. McIL-17-3 could activate downstream NF-kappa b and was negatively regulated by Mc-novel_miR_145. Moreover, Mc-novel_miR_145 could alleviate LPS-induced apoptosis by negatively regulating McIL-17-3.

Summary: The newly identified member of the IL17 family, McIL17-1, plays an important role in the innate immune response to bacterial infection in M. coruscus. It is expressed in various tissues with high levels in gills, hemocytes, and digestive glands. McIL17-1 is upregulated after stimulation with different pathogen associated molecular patterns (PAMPs) and has a cytoplasmic localization in HEK293T cells. Knockdown of McIL17-1 reduces mortality rate in response to Vibrio alginolyticus infection, while overexpression increases mortality rate.
