摘要: 蛋鸭输卵管在产蛋过程中需要持续经历组织重塑、细胞更新和稳态维持,其中成纤维细胞作为主要间质细胞,在细胞外基质重塑、上皮分化支持及平滑肌功能维持中发挥基础作用。免疫球蛋白Kappa J区重组信号结合蛋白(recombination signal binding protein for immunoglobulin kappa J region,RBPJ)是Notch信号通路的重要效应因子,可通过调节细胞的增殖分化,影响组织发育、形态和功能。然而,RBPJ是否通过影响鸭输卵管成纤维细胞进而调控蛋鸭输卵管功能的研究尚未见报道。本研究通过细胞培养、RNA干扰(RNAi)和转录组学分析,探讨RBPJ对鸭成纤维细胞活力和增殖的影响及其对下游基因表达的调控作用。结果表明:(1)成功分离鸭胚成纤维细胞,并构建RBPJ干扰细胞模型;(2)RBPJ基因干扰后,鸭胚成纤维细胞活力(12 h)和增殖能力(24 h)显著(p<0.05)降低;(3)RBPJ基因干扰后引起364个基因差异表达,这些差异基因显著富集在MAPK和钙信号通路等信号通路中。综上,RBPJ基因通过调节PLA2G4CAREG基因表达影响MAPK信号通路,通过调节FGF9NTRK3AGTR1基因表达影响钙信号通路,进而影响细胞增殖。研究结果弥补了RBPJ对鸭胚成纤维细胞增殖功能影响的研究空白,同时也为后续解析RBPJ对鸭输卵管成纤维细胞的功能奠定了研究基础,并在实际生产中为提高产蛋性能提供理论基础和科研支撑。

Abstract:

During the egg-laying process, the oviduct of laying ducks must continuously undergo tissue remodeling, cell renewal, and homeostasis maintenance. Among these processes, fibroblasts, as the primary stromal cells, play a fundamental role in extracellular matrix remodeling, supporting epithelial differentiation, and maintaining smooth muscle function. The recombination signal binding protein for immunoglobulin kappa J region (RBPJ) is an important effector of the Notch signaling pathway, which regulates cell proliferation and differentiation, thereby affecting tissue development, morphology, and function. However, whether RBPJ regulates the function of duck oviduct by influencing duck oviduct fibroblasts has not yet been reported. This study investigated the effects of RBPJ on the viability and proliferation of duck embryo fibroblasts and its regulatory role in downstream gene expression through cell culture, RNA interference (RNAi), and transcriptome analysis. The results showed that: (1) Duck embryo fibroblasts were successfully isolated and RBPJ-interfered cell models were successfully constructed; (2) RBPJ gene interference significantly (p<0.05) reduced the viability at 12 h and the proliferation ability at 24 h of duck embryonic fibroblasts; (3) After RBPJ gene interference, 364 genes were differentially expressed and these significantly enriched in signaling pathways such as the MAPK and calcium signaling pathways. In conclusion: RBPJ affects the MAPK signaling pathway by regulating the expression of the PLA2G4C and AREG genes, and affects the calcium signaling pathway by regulating the expression of the FGF9, NTRK3, and AGTR1 genes, thereby affecting cell proliferation. These findings fill the research gap regarding the role of RBPJ in the proliferation of duck embryo fibroblasts. Moreover, they lay a research foundation for future analysis of RBPJ functions in duck oviduct fibroblasts and provide a theoretical basis and scientific support for improving egg-laying performance in practical production.
