Summary: This study investigated the role of mucin genes in growth traits in Bengal ducks and found that glycosylation and EGF1 are important domains for growth traits in ducks. Real-time PCR analysis showed that high-growing ducks had a better expression profile for the mucin gene compared to low-growing ducks. Thus, the mucin gene may serve as a marker for growth traits.

Summary: Obesity leads to chronic low-grade inflammation, causing diabetes, steatosis, and insulin resistance. Activation of the p38 pathway in macrophages plays a crucial role in this inflammation, suggesting p38 inhibition as a potential treatment for obesity comorbidities. However, lack of p38 activation in myeloid cells worsens high-fat diet-induced obesity, diabetes, and steatosis. Deficient p38 activation increases macrophage IL-12 production, leading to inhibition of hepatic FGF21 and reduction of thermogenesis in the brown fat.

Summary: The One Health approach reveals the global spread of Salmonella enterica subsp. diarizonae and its antimicrobial resistance in animals and humans. This study identified the presence of S. enterica subsp. diarizonae in a migrating mallard duck in Poland, highlighting the potential role of wild birds in the spread of intestinal microbes and antibiotic resistance. The isolated strain showed high resistance to multiple antimicrobial agents.

Summary: This study found differences in gene expression profiles related to lipid metabolism in the liver, sebum, and abdominal fat of fatty-type and lean-type ducks. The differentially expressed genes were enriched in various pathways, with key genes identified for lipid deposition in different tissues of ducks. These results provide insights into transcriptome regulation in lipid deposition and may aid in duck breeding.

Summary: This study identified the full-length cDNA sequence of duck SP3 (duSP3) and confirmed its constitutive expression in multiple tissues, with a significant increase in expression after stimulation with hepatitis virus and polyriboinosinic polyribocytidylic acid. The results suggest that SP3 may play a positive role in immune responses against viral infections in ducks.

Summary: Transportation has conflicting effects on the release of stress hormones in poultry. The avian HPA axis, involving corticosterone and cortisol, is different from that of mammals. Simply measuring adrenal hormones may not be sufficient to determine a bird's welfare status, as stressors can have longer-lasting effects on the brain. Therefore, it is important to prevent additional stressors from occurring after transportation to protect the health, welfare, and production of the birds.

Summary: Naringenin, an activator found in citrus fruits, has beneficial effects on thermogenesis and insulin sensitivity. Our study investigated if carotenoids can enhance the metabolic effects of naringenin on adipocytes. Results showed that beta-carotene acts synergistically with naringenin to improve thermogenesis and glucose metabolism genes.

Summary: Age-related changes in bone microstructure were studied in domestic ducks and ring-necked pheasants using high-resolution 3D imaging. The growth patterns, limb function, and biological characteristics differed between the two species. These findings are important for understanding the biology of extant and fossil birds.

Summary: Birds perceive light differently than mammals, with deep brain photoreceptors playing a role in seasonal fertility. A study found that birds express high levels of photoreceptor OPN4 on the day of hatching, suggesting additional functions beyond reproduction. The ontogeny of deep brain photoreceptors was analyzed, showing that ducks exhibit adult-like OPN4 gene expression on Day 0, with peak expression levels at week 19 coinciding with peak fertility.

Summary: A qualitative analysis of mallard ducks' tissues and organs revealed the potential hygienic and toxicological threats related to lead and cadmium concentrations. The study found that mallards have a measurable response to environmental pollution with lead and cadmium, making them potential bioindicators of contamination levels. The ban on lead pellets in Poland may help reduce lead contamination in mallards' tissues and organs.

Summary: The study demonstrates the association between PPARG and metastasis in prostate cancer, with PPARG over-expression leading to increased levels of AKT3, which in turn enhances PGC1α localization in the nucleus, driving mitochondrial biogenesis and providing higher energetic output for tumor cell progression towards metastasis through EMT.
