Effects of AFP-172 on COX-2-induced angiogenic activities on human umbilical vein endothelial cells.

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
purposeTo investigate the angiogenic effect of the free acid of tafluprost (AFP-172) on human umbilical vascular endothelial cells (HUVECs).
methodsHUVECs cultured in the presence or absence of FP receptor antagonist (10 nM AL-8810) were exposed to escalating concentrations of 10(-7), 10(-6), 10(-5), 10(-4) and 10(-3) M AFP-172 (the free acid of tafluprost). For cell proliferation assays, the numbers of cells were derived from a CellTiter96® Aqueous One Solution Cell Proliferation Assay (Promega) by Microplate reader (Bio-Rad, Benchmark). Endothelial cell migration was evaluated by a BD Biocoat™ Angiogenesis System using FluoroBlok ™ 24-well inserts (BD Biosciences, Bedford, MA). BioTek FLx800 fluorescence plate reader was used for quantitative measurement of fluorescently-labeled invasive vascular endothelial cells. Endothelial capillary-like tube formation was evaluated by BD Biocoat Angiogenesis System using Matrigel Matrix 96-well plate. Real-time quantitative reverse transcriptase-polymerase chain reaction (RT-PCR) was used to assess the gene expression of vascular endothelial growth factor (VEGF), cyclooxygenase-2 (COX-2) and endothelial nitric oxide synthase (eNOS). COX-2 protein was detected by immunofluorescent staining and Western blot assay. Student's t-test was used for statistical analysis.
results10(-4) M AFP-172 treated cells stimulated the proliferation, migration and tube formation of HUVECs as compared to 10(-5), 10(-6,) 10(-7) M AFP-172 treated cells and control (P < 0.01). RT-PCR showed that incubation of HUVECs with 10(-4) M AFP-172 stimulated the expression of COX-2 mRNA (P < 0.05). Western blot assay revealed that AFP-172 caused cells to increase in COX-2 protein at the concentrations of 10(-4) M.
conclusions>AFP-172 showed the angiogenic effects on HUVECs at the concentrations of 10(-4) M by inducing COX-2 protein.
