OPN3-mediated positive regulation of angiogenesis in HUVECs through VEGFR2 interaction.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Many rhodopsin-like G-protein-coupled receptors (Rh-GPCRs) are known to either promote or inhibit angiogenesis. Among these, Opsin 4 and Opsin 5 are specifically involved in vascular development within the eye. Opsin 3 (OPN3), another member of Rh-GPCRs, performs a variety of light-dependent and light-independent functions in extraocular tissue. However, its role in endothelial cells and angiogenesis remains unclear. Here, we found that OPN3 knockdown or knockout in zebrafish impairs embryonic angiogenesis and vascular development. Similarly, silencing OPN3 in human umbilical vein endothelial cells (HUVECs) inhibits cellular proliferation, migration, sprouting, and tube formation, while OPN3 overexpression promotes these cellular processes. Moreover, OPN3 regulates angiogenesis in HUVECs through the VEGFR2-AKT pathway, with OPN3 and VEGFR2 co-localizing at the plasma membrane and forming a physical complex. These findings provide new insights into the non-light-dependent functions of OPN3 in angiogenesis, expanding our understanding of its physiological roles and offering potential therapeutic strategies for angiogenesis-related diseases.
