Recently, against the background of increasing land salinization and global warming, many studies have examined the mechanisms of freshwater fish adaptation to elevated salinity. However, the mechanisms underlying salinity tolerance in the kidney of Micropterus salmoides, a popular saline aquaculture species, remain poorly understood. We used RNA-seq to explore the differentially expressed genes (DEGs) in the kidney of M.

Background: Atrial fibrillation (AF) is a prevalent cardiac arrhythmia associated with substantial morbidity and mortality. Oxidative stress (OS) has been implicated in the pathogenesis of AF, suggesting that targeting OS-related genes could offer novel therapeutic opportunities. This study aimed to identify causal OS-related genes contributing to AF through a comprehensive multi-omics Summary-based Mendelian Randomization (SMR) approach.

Article Synopsis
  • Opsins are proteins that help in sensing light, with short wavelength-sensitive opsin 2 (2) specifically detecting blue light and being crucial for melanocyte formation in fish.
  • Researchers focused on the 2 gene in a reef fish, discovering it encodes a protein of 351 amino acids, mainly expressed in the eye and skin, and localized in specific cells responsible for vision and pigmentation.
  • Knocking down the 2 gene led to a decrease in black pigmentation and melanin-related activity, while red pigmentation and carotenoid levels increased, indicating that the 2 gene plays a key role in regulating skin color by influencing vitamin synthesis and melanin expression.

Fish skin color is usually strongly affected by the background color of their environment. The study investigated the effects of five different background colors on the skin color of leopard coral groupers (Plectropomus leopardus). More than 450 juveniles were reared in Blue, Red, Black, White, and Transparent background tanks for 56 days.

In traditional dual-ion systems, the cathode usually is employed as anion-storage materials. Herein, we propose a new dual-ion hybrid supercapacitor with reverse anion/cation-storage mechanism, consisting of a mesoporous (MPs) VN anode as a pivotal anion-storage material and KMnO nanosheet arrays grown on carbon cloth (NSs/CC) as (K-storage) cathode. During charge/discharge, the anode and cathode reversibly store/release OH ions and K ions, respectively.

  • Animal growth and development is regulated by multi-genes, with myostatin (Mstn) acting as a negative regulator and myogenin (Myog) as a positive regulator crucial for muscle cell generation.
  • Researchers cloned full-length mstn-1, mstn-2, and myog genes from the economically important fish species Trachinotus blochii to understand their role in muscle growth.
  • Analysis showed that mstn and myog genes are highly conserved across species, with differing expression patterns in various tissues and influences from nutritional and environmental factors, indicating their significant roles in muscle growth and potentially other biological functions in fish.

Lithium-sulfur (Li-S) batteries show great potential in future electric transportation and large-scale grid storage applications because of their attractive theoretical energy density (2600 W h kg) and relatively abundant sulfur reserves. However, the rapid capacity decay and unsatisfactory sulfur loading caused by the lithium polysulphide (LiPS) dissolution and low electrical conductivity of sulfur are the most urgent issues plaguing its practical applications. Herein, we report a multifunctional nanoporous (NP) VN/VO binary host that can efficiently resolve the above conflicts by the synergy between the functions of two materials.

Article Synopsis
  • - Golden Pompano has become a key fish species in Chinese aquaculture, but its rapid growth leads to high mortality rates due to low oxygen levels (hypoxia), causing significant economic losses.
  • - Researchers identified single nucleotide polymorphisms (SNPs) and genes linked to hypoxia tolerance by analyzing different fish groups, revealing that multiple genetic linkage groups, particularly 18 and 22, play a role.
  • - Key genes related to energy metabolism, immune response, and stress were found in the brain and liver; mutations in these genes may affect how the fish metabolize glucose and respond to hypoxic stress, potentially determining their tolerance levels.

Hybrid supercapacitors (HSCs) with the characteristics of high energy density, long cycle life and without altering their power density need to be developed urgently. Herein, a novel dual-ion hybrid supercapacitors (DHSCs) with Ni(OH) nanotube arrays (NTAs) as positive electrode and VO directly grown on freestanding carbon nanotubes (CNTs) as negative electrode is assembled. In charging mechanism of DHSCs, K are inserted into the VO negative while OH react with Ni(OH) positive; during discharge, the K and OH are released from VO negative and Ni(OH) positive, respectively, and return back to the electrolyte, which is quite different from traditional metal ion or alkaline supercapacitors.

The enhancer of zeste homologue 2 (EZH2) is a histone H3 lysine 27 methyltransferase that promotes tumorigenesis in a variety of human malignancies by altering the expression of tumour suppressor genes. To evaluate the prognostic value of EZH2 in glioma, we analysed gene expression data and corresponding clinicopathological information from the Chinese Glioma Genome Atlas, the Cancer Genome Atlas and GTEx. Increased expression of EZH2 was significantly associated with clinicopathologic characteristics and overall survival as evaluated by univariate and multivariate Cox regression.

In recent years, largemouth bass have become one of the most commonly aquacultured species in China, however, its low survival rate during larval weaning has always been a bottleneck that has restricted industrial development. Understanding the changes in liver metabolism and intestinal microflora during the weaning of largemouth bass larvae can help to design better weaning strategies and improve survival. In this study, liver mRNA and intestinal microflora 16S rRNA genes were analyzed using high-throughput sequencing at the pre, mid, and post weaning stages [15, 30, 45 days post hatching; total length (cm) were 2.
