Slc2a6 is a member of the slc2 family (solute carrier 2 family) and previous reports have indicated its involvement in the inflammatory response. Slc2a6 is regulated by the NF-ĸB signaling pathway. This study investigated the differential expression of slc2a6 in the early embryonic development of Japanese flounder, revealing that the early gastrula stage had the highest level of slc2a6 expression. Moreover, slc2a6 expression was increased in vitro after stimulation by lymphocystis disease virus (LCDV), and in vivo experiments also showed significantly elevated levels in the spleen and muscle tissues following LCDV stimulation. Subcellular localization revealed that Slc2a6 was expressed in both the nucleus and cytoplasm of cells. The pcDNA3.1-slc2a6 overexpression plasmid was successfully constructed; the si-slc2a6 interfering strand was screened and samples were collected. The expression of NF-ĸB signaling pathway-related genes il-1β, il-6, nf-ĸb, and tnf-α was evaluated in overexpressed, silenced, and LCDV-stimulated samples. The results showed that slc2a6 is involved in viral regulation in Japanese flounder by regulating innate immune responses.

Due to the discharge of industrial wastewater, urban domestic sewage, and intensive marine aquaculture tailwater, nitrate (NO) pollution has emerged as a significant issue in offshore waters. Nitrate pollution affects aquatic life and may interact with other pollutants, leading to comprehensive toxicity. Cadmium (Cd) is the most widespread metal contaminant, adversely affecting aquatic life in the coastal waters of China.

Japanese flounder is usually gonochoristic, with gonads that are either testes or ovaries. Here, we report an unusual case of hermaphroditism in Japanese flounder captured from the Bohai Sea. In the intersex flounder, the membrane of the upper ovary was closely connected to the abdominal muscles and internal organs, and the eggs filled the entire abdomen.

Rbpms2, an RNA-binding protein with multiple splicing (Rbpms), can interact with RNAs to involve oocyte development, thereby influencing female sex differentiation in vertebrates. Here, two splicing variants of the Rbpms2 gene from Japanese flounder (Paralichthys olivaceus) were identified, namely Rbpms2.1 and Rbpms2.

Ras-related associated with diabetes (RRAD) is a member of the Ras GTPase superfamily that plays a role in several cellular functions, such as cell proliferation and differentiation. In particular, the superfamily acts as an NF-κB signaling pathway inhibitor and calcium regulator to participate in the immune response pathway. A recent transcriptome study revealed that was expressed in the spleen of disease-resistant Japanese flounder () individuals compared with disease-susceptible individuals, and the results were also verified by qPCR.

As an important CXC chemokine, CXCL8 plays pleiotropic roles in immunological response. In teleost, CXCL8 is involved in cell migration and bacterial invasion. However, the immune antibacterial function of CXCL8 in Japanese flounder (Paralichthys olivaceus) (PoCXCL8) is largely scarce.
