Summary: In the last two decades, fish industry by-products have been used to extract type I collagen due to issues with traditional mammalian tissue extraction. This study focused on fish by-products from aquaponic plants as a source of biopolymers, aiming to create eco-friendly and profitable materials. The research evaluated the impact of age on the properties of Tilapia skin for collagen extraction, identifying significant age-related differences in thickness, collagen fiber bundle diameter, organization, orientation, thermal properties, mechanical properties, and composition.

Summary: The study identified a lect2 gene from Nile tilapia (On-lect2) and characterized its roles in the fish's immune response against bacterial infection. On-LECT2 plays important functions in promoting inflammation, reducing tissue damages, and improving survival rate of Nile tilapia during bacterial infection, with the highest transcriptional levels in the liver.

Summary: This study evaluated the potential of active peptides from tilapia skin collagen as DPP-IV inhibitors using in silico method. The results showed that the enzymatic hydrolysis of collagen produced active peptides with better biological activity prediction. Docking simulations revealed the interaction between active peptides and DPP-IV through various forces. Some active peptides exhibited higher binding affinities compared with linagliptin. These findings suggest that fish skin waste could be utilized as a functional compound to treat type-2 diabetes mellitus.

Summary: This study found that replacing soybean meal protein with cottonseed protein concentrate can improve the flesh quality of Nile tilapia. Cottonseed protein concentrate can reduce muscle lipid content and alter muscle texture. In addition, the intake of cottonseed protein concentrate can suppress hepatic lipid synthesis and promote lipid breakdown.

Summary: A 12-week trial showed that tilapia has higher tolerance to a high lipid diet than a high carbohydrate diet. Continuous feeding of the high carbohydrate diet impaired tilapia's appetite, weight gain rate, and immune response. Tilapia's distribution of fat may be a risk-avoidance strategy in response to a continuous high lipid diet.

Summary: Exposure to Butylparaben (BuP) induces darker skin pigmentation in Nile tilapia by interfering with melanin synthesis genes and neurotransmitter levels. BuP inhibits phototransduction from the retina to the brain, resulting in increased melanin synthesis and decreased opsin expression.

Summary: This study successfully cloned TiLV ORF10 into the pcDNA3.1 vector as a vaccine candidate and showed that vaccination with pcDNA3.1-ORF10 can significantly upregulate the transcription levels of immune-related genes, reduce virus replication, and enhance protective effects against TiLV in tilapia.

Summary: This study discovered an IL8 gene from Nile tilapia and found that it plays a crucial role in acute bacterial infections. The gene codes for 94 amino acids and is highly expressed in the head-kidney tissue and induced by Streptococcus agalactiae and Aeromonas hydrophila. In vitro experiments showed that IL8 regulates various immune processes and promotes inflammation. These findings are significant for further understanding the protective effects of IL8 in bony fish against bacterial infections.

Summary: Mathematical models can be used to estimate the body composition of fish without sacrificing animals. In this study, Nile tilapia body composition data were collected from 138 scientific publications, and predictive models were developed using different combinations of models and calibration methods. The results showed that model predictions are influenced by the type of model, calibration method, and amount of calibration data available. The best predictive models for Nile tilapia body composition were the allometric model and a robust hybrid model, both calibrated assuming multiplicative error.

Summary: The research reveals that pyraclostrobin mainly enters fish through the gills, with the most severe toxic effects observed in the gills, potentially causing oxidative damage, changes in ventilation frequency, and other reactions. This indicates that the gills are important target organs for pyraclostrobin toxicity.

Summary: This study investigates the evolution of a giant sex chromosome in cichlid fish, finding that it consists of three distinct regions and contains unprecedented amounts of endogenous retroviral elements, immunoglobulin genes, and long non-coding RNAs. Comparative analysis across 69 teleost genomes supports the hypothesis that the giant sex chromosome originated from the fusion of a B chromosome.

Summary: This study conducted genome-wide identification and comprehensive analysis of the SDR superfamily in 29 animal species, revealing that the number of SDR genes in animals increased with whole genome duplication, and vertebrate SDRs were clustered into five categories. Tandem duplication of specific SDR genes was observed in different animal groups, and sexually dimorphic expression of certain SDRs in adult fish gonads was confirmed by in situ hybridization and qPCR, suggesting their potential roles in steroidogenesis and gonadal differentiation.

Summary: Life on Earth has evolved from simplicity to complexity, with bacteria and archaea excelling in metabolic diversification and eukaryotes displaying morphological innovation. The Earth BioGenome Project proposes sequencing the genomes of all known eukaryotic species to create a digital library of life, which will help address evolutionary and ecological questions and provide insights into speciation, adaptation, and organismal dependencies within ecosystems.

Summary: Nile tilapia and Mozambique tilapia exhibit differential gene expression in response to salinity challenges, reflecting their varying salt tolerance capabilities. Both species show immune and cell stress responses as well as turnover of ionocytes in response to salinity, but the specific genes expressed differ between the two, indicating unique transcriptomic architectures and potentially contributing to their osmoregulation abilities in high salinities.

Summary: In adaptive radiations, the source of genetic variation and the genomic architecture play a significant role in the adaptation of organisms to new niches. This study investigated the genomic changes associated with the repeated invasion of freshwater niches by threespine stickleback. The findings suggest that the genomic architecture of parallel adaptation depends on the steepness of ecological gradients and the dimensionality of the niche space.

In this study, a high-contiguity chromosome-level genome assembly on a YY southern catfish was generated using Nanopore and Hi-C technologies. The study identified a candidate sex-determining gene in the sex-determining region and confirmed the role of amhr2y in male sex determination.

Summary: The European polecat population in Great Britain has increased due to legal protection and hybridization with feral domestic ferrets, resulting in viable offspring. Whole-genome sequencing and population genomics methods reveal a high degree of genome introgression in British polecats, even in individuals phenotyped as pure polecats. Introgressed genes associated with cognitive function and sight have been identified.

Summary: African cichlids are ideal for studying genes responsible for mate choice and species divergence. By studying these fishes, researchers have identified quantitative trait loci and candidate genes that influence cone opsin expression. However, experimental results on the effect of the MITFA gene on opsin expression contradict expectations.
