Podocyte biology is an important key factor for the maintenance of glomerular function and structure. Nephronectin is a podocyte-derived extracellular matrix protein in the glomerular basement membrane. Suppression of nephronectin expression by microRNA-378a-3p significantly induced proteinuria due to loss of integrity of the glomerular filtration barrier in zebrafish and mice, demonstrating the relevance of the microRNA-nephronectin axis in regulation of the podocyte-glomerular basement membrane interaction and integrity of the glomerular filtration barrier.
足细胞生物学是维持肾小球功能和结构的重要关键因素。纤连蛋白是肾小球基底膜中足细胞衍生的细胞外基质蛋白。miR-378a-3p 对纤连蛋白表达的抑制作用显著诱导了斑马鱼和小鼠的蛋白尿，这是由于肾小球滤过屏障完整性的丧失，表明 microRNA-纤连蛋白轴在调节足细胞-肾小球基底膜相互作用和肾小球滤过屏障完整性方面的相关性。
