Abstract
Lumen formation, as a key process of biological tube construction, is essential in various physiological processes such as nutrient and waste transporting, gas exchanging, and structural supporting. However, the mechanisms underlying tubular lumen development are still not fully understood. In the present study, we identified a matrix metalloproteinase, Nas15, which is enriched in the apical domain of the Ciona embryonic notochord. The expression level of the Nas15 gene significantly increased during notochord lumen formation and expansion. Nas15 loss-of-function resulted in abnormal notochord lumen expansion in Ciona embryos. Besides, yeast two-hybrid screening and CO-IP results indicated a Phosphatase 2 Catalytic Subunit Alpha (PPP2CA) physically interacted with Nas15. PPP2CA also involved in notochord lumen formation via localizing Nas15. Furthermore, we investigated the distribution of laminin in Nas15 disrupted embryos. In conclusion, our results revealed a mechanisms of how notochord cells regulating lumen expansion via metalloproteinase-mediated ECM localization. This findings provide insight into the mechanisms of tubular organ lumen formation and serve as a reference for research on human abnormal lumenogenesis diseases.
期刊介绍：
Frontiers in Ecology and Evolution publishes rigorously peer-reviewed research across fundamental and applied sciences, to provide ecological and evolutionary insights into our natural and anthropogenic world, and how it should best be managed. Field Chief Editor Mark A. Elgar at the University of Melbourne is supported by an outstanding Editorial Board of international researchers. This multidisciplinary open-access journal is at the forefront of disseminating and communicating scientific knowledge and impactful discoveries to researchers, academics and the public worldwide.
Eminent biologist and theist Theodosius Dobzhansky’s astute observation that “Nothing in biology makes sense except in the light of evolution” has arguably even broader relevance now than when it was first penned in The American Biology Teacher in 1973. One could similarly argue that not much in evolution makes sense without recourse to ecological concepts: understanding diversity — from microbial adaptations to species assemblages — requires insights from both ecological and evolutionary disciplines. Nowadays, technological developments from other fields allow us to address unprecedented ecological and evolutionary questions of astonishing detail, impressive breadth and compelling inference.
The specialty sections of Frontiers in Ecology and Evolution will publish, under a single platform, contemporary, rigorous research, reviews, opinions, and commentaries that cover the spectrum of ecological and evolutionary inquiry, both fundamental and applied. Articles are peer-reviewed according to the Frontiers review guidelines, which evaluate manuscripts on objective editorial criteria. Through this unique, Frontiers platform for open-access publishing and research networking, Frontiers in Ecology and Evolution aims to provide colleagues and the broader community with ecological and evolutionary insights into our natural and anthropogenic world, and how it might best be managed.
