Article Abstract
Aeromonas salmonicida (A. salmonicida) is a pathogenic bacterium that causes serious problems in the global Atlantic salmon aquaculture industry. In this study, we comprehensively analyzed the profiles of lncRNAs, miRNAs and mRNAs in gills of Atlantic salmon at high-dose A. salmonicida infection (3.06 × 10 CFU/mL), low-dose A. salmonicida infection (3.06 × 10 CFU/mL), and a PBS (100 μL) control. We identified 65 differentially expressed lncRNAs, 41 miRNAs, and 512 mRNAs between the control group and infection groups. Functional analysis showed that these genes were significantly enriched in the p53 signaling pathway, Wnt signaling pathway, mTOR signaling pathway, JAK-STAT signaling pathway, and Toll-like receptor signaling pathway. In addition, we predicted key genes in immune-related pathways and constructed a lncRNA-miRNA-mRNA network based on whole transcriptomic analysis. We further predicted three lncRNA-miRNA-mRNA axes as potential novel biomarkers in regulating the immune response of Atlantic salmon against A. salmonicida infection.

Maintaining a healthy pool of circulating red blood cells (RBCs) is essential for adequate perfusion, as even minor changes in the population can impair oxygen delivery, resulting in serious health complications including tissue ischemia and organ dysfunction. This responsibility largely falls to specialized macrophages in the spleen, known as red pulp macrophages, which efficiently take up and recycle damaged RBCs. However, questions remain regarding how these macrophages are acutely activated to accommodate increased demand.

Migraine is a complex neurological disorder involving multiple neuropeptides that modulate nociceptive and sensory pathways. The most studied peptide is calcitonin gene-related peptide (CGRP), which is a well-established migraine trigger and therapeutic target. Recently, another peptide, pituitary adenylate cyclase-activating polypeptide (PACAP), has emerged as an alternative target for migraine therapeutics.

Phototaxis is a critical behavior in insects and is closely linked to vision and environmental adaptation. Understanding how insects perceive light and exhibit phototactic responses is crucial for assessing the ecological impact of artificial light at night. However, the molecular and neural mechanisms that regulate phototactic responses in insects remain largely unknown.

Kinesin family member 14 (KIF14) has been implicated in the progression of multiple cancer types, yet its role in colorectal cancer (CRC) metastasis remains undefined. Here, we assesse KIF14 expression in CRC specimens and explore its clinical and functional significance. KIF14 upregulation is frequently observed in CRC tissues and is correlated with advanced tumor stage and reduced overall survival.

Microglia, the resident immune cells of the central nervous system (CNS), are involved in the pathogenesis of neurodegenerative diseases, such as Alzheimer's disease (AD), Dementia with Lewy Bodies (DLB), and Parkinson's disease (PD). 14-3-3 proteins act as molecular hubs to regulate protein-protein interactions, which are involved in numerous cellular functions, including cellular signaling, protein folding, and apoptosis. We previously revealed decreased 14-3-3 levels in the brains of human subjects with neurodegenerative diseases.
