- Pheromones are key modulators of reproductive behavior in fish, and certain odorant receptors (ORs) expressed in the olfactory epithelium act as receptors for sex pheromones. The northern snakehead (Channa argus) exhibits distinctive parental care behaviors, such as nest construction and brood guarding. It is likely that hormonal regulation during the breeding season upregulates the expression of olfactory receptors, thereby enhancing the sensitivity of C. argus to pheromones released by the opposite sex and ultimately promoting the initiation of reproductive behaviors. A total of 256 functional OR genes were identified from the C. argus genome, and these were distributed across four chromosomes. Transcriptome sequencing of whole-brain and olfactory rosette tissues from males during and after the breeding season showed a marked upregulation of the olfactory receptor gene caor67 in the olfactory rosettes, as well as increased expression of prolactin (PRL) in the brain. The open reading frames (ORFs) of caor67, prl, prlra, prlrb, stat5a, and stat5b from northern snakehead were cloned and characterized. The expression of caor67 is highest in the olfactory rosettes. During the breeding season, the expression of caor67 in the male olfactory rosettes is significantly higher than in females. prl expression is relatively high in the pituitary, while prlra shows the highest expression in the gills, followed by the olfactory rosettes. prlrb has the highest expression in the olfactory rosettes, followed by the gills and kidney. In situ hybridization results show that the mRNA of caor67, prlra, and prlrb is expressed in the sensory epithelium of the C. argus olfactory rosettes, with expression detected in both ciliated and microvillous olfactory receptor neurons (ORNs). Co-localization of caor67 with prlra and prlrb was observed in the ORNs of the olfactory rosettes. Recombinant C. argus PRL (rPRL) was expressed and purified, and functional assays confirmed that it interacts with both PRLRa and PRLRb to enhance phosphorylated STAT5 (pSTAT5) activity. Overexpression of PRLRa/PRLRb or STAT5a/STAT5b significantly increased caor67 promoter-driven luciferase activity in vitro. Treatment with the JAK2 inhibitor TG101348, which blocks the JAK2-STAT5 signaling pathway, significantly reduced luciferase activity, indicating that PRL regulates the transcription of caor67 via the PRLR-JAK2-STAT5 signaling pathway. - Source: PubMed

SMAD7 is an established intracellular antagonist of TGF-β signaling, but its specific role within NK cells remains poorly defined. - Source: PubMed

Ye Matthew TZuo ZhuangCalin StelianaYang YalingYou M James - Fostering STAT5 signaling is key to immunotherapies that leverage CD8 T cell biology. Using mouse models, we demonstrate that the two mammalian STAT5 paralogs, STAT5A and STAT5B, are at once redundant and functionally distinct in CD8 T cells. Thus, they are asymmetric paralogs, exhibiting both widespread homology at molecular level and functional asymmetry at cellular level, with STAT5B emerging as dominant. For mechanisms, we determined that STAT5B is twice as abundant, accounting for two-thirds of the total STAT5 pool, and present evidence that it also has distinct, paralog-specific properties. We also defined cytokine- and cell state-restricted STAT5B functions and devised a core signature that spotlights key downstream properties and serves as bioinformatic probe. Together, these studies affirm the centrality of STAT5 in CD8 T cells, reveal common and circumscribed activities for STAT5A and STAT5B, and present a unifying model that foregrounds both redundancy and asymmetry. - Source: PubMed

Ristin SvetlanaDalzell MollyArmstrong ChristopherIlsin NisaFontanella Antonio MNivelo LuisHennighausen LotharO'Shea John JVillarino Alejandro V - This study aimed to comprehensively characterize the relationship between glycated hemoglobin (HbA1c) and intervertebral disc degeneration (IVDD) by integrating population-level epidemiological profiling, Mendelian randomization (MR) analysis, multi-omics data, and single-cell transcriptomics. The objectives included clarifying the causal effect of HbA1c on IVDD, identifying key HbA1c-related genes, elucidating their cellular and molecular roles in disc degeneration, and exploring potential therapeutic targets. Global Burden of Disease (GBD) 2021 database was used to evaluate the incidence rate of diabetes mellitus (DM) and low back pain (LBP) across the entire global population. To assess the causal effect of HbA1c on IVDD, MR approache was conducted using summary statistics from large genome-wide association studies. Subsequently, integrating cis-eQTL information, bulk RNA sequencing, and single-cell RNA sequencing were performed to identify HbA1c-related genes involved in disc degeneration, and explore their roles along pseudotime differentiation trajectories. Potential associations between hub genes and IVDD, as well as candidate therapeutic compounds targeting these genes, were further evaluated through database screening and molecular docking. The findings from GBD indicated a correlation between diabetes and low back pain in both 1990 and 2021. The results of MR analysis revealed a causal relationship between HbA1c levels and IVDD. After integrated analysis of the eQTLGen database and RNA-seq data, we identified five hub HRGs, including STAT5A, CDKN1C, TRPS1, NME4, and OASL, which have been implicated in multiple biological processes and pathways associated with IVDD. Moreover, the scRNA-seq analysis showed that hub HRGs were associated with specific cell subpopulations in human nucleus pulposus (NP) tissues, such as inflamed chondrocytes, fibrochondrocytes, chondrocytes, and calcifying chondrocytes. Additionally, hub HbA1c related genes (HRGs) have been found to be associated with several DDDs such as back pain, osteoporosis, and spinal stenosis. Meanwhile, 12 drugs, including resveratrol, dexamethasone, and simvastatin, were identified that have the potential to target hub HRGs. This study revealed a causal effect of HbA1c on IVDD and identified five key HbA1c-related genes (STAT5A, CDKN1C, TRPS1, NME4, and OASL) involved in disc degeneration, providing potential targets for future research. - Source: PubMed
