Figure Lengend Snippet: A Schematic Diagram of LncRNA-URRCC-Based Signaling Pathway in ccRCC cells proliferation and invasion. LncRNA-URRCC upregulates AKT signaling by directly targeting EGFL7 via mediating histone H3 acetylation of EGFL7 promoter, and then inducing cell growth and invasion. AKT signaling downstream FOXO3 in turn downregulates URRCC by directly binding to its promoter

doi: 10.1038/s41598-021-97482-2

Figure Lengend Snippet: EGFL7 levels in non-pregnant women, healthy pregnant women, and pregnant women affected by IUGR, Early PE and Late PE.

Data were compared using the two-sample t -test between two samples ( p < 0.001 for e-PE vs. CTRL and IUGR at GA 22–25; p = 0.05 for e-PE vs. CTRL and IUGR at GA 26–30; p = 0.045 for e-PE vs. IUGR at GA 31–34; p = 0.01 for l-PE vs. CTRL) or ANOVA test among the three studied groups ( p < 0.001 at GA 22–25 and p = 0.036 at GA 35–40). Statistically significant difference within gestational interval is reported. SigmaPlot 12.0 and GraphPad Prism 7 were used for statistical analysis.
