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

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

Article Snippet: Immunohistochemistry for the target molecules was performed on paraffin sections using a primary antibody against EGFL7 (1:50, proteintech, 19,291–1-AP), FOXO3 (1:500, Abcam, ab12162), P-AKT (1:50, Abcam, ab131443), Ki67 (1:500, Abcam, ab92742) and the proteins in situ were visualized with 3, 3-diaminobenzidine.

PLA signals were counted and plotted as a bar graph (n=5), Scale bar=20 mm (F). *P<0.01 vs control IgG; **P<0.01 vs neutralizing anti-Nrg1 antibody+PM. G–J, HCAECs were transfected with ErbB4 siRNA, treated with PM for 1 h., and the cell lysates were prepared and analyzed for ErbB2 tyrosine phosphorylation (G), Src activation (H), or eNOS tyrosine phosphorylation (I). An equal amount of protein from cell lysates was analyzed for eNOS activity (J). *P<0.01 vs nontarget (NT) siRNA; **P<0.01 vs NT siRNA+PM (ANOVA). K, To study the role of ErbB2 and ErbB4 in NO formation in coronary arteries, left coronary artery were isolated and incubated with control IgG, neutralizing anti-ErbB2 or neutralizing anti-ErbB4 antibodies, and NO release in response to ACh (10 µmol/L) was determined by electron spin resonance (EPR) using Fe- (MGD)2. L, Spin count of the NO-Fe(MGD)2 was calculated from EPR signals were plotted as a bar graph. *P<0.01 vs control IgG (ANOVA).

a The distribution of circulating Mfge8 concentrations by MFGE8 genotypes. b The distribution of serum triglyceride levels by MFGE8 genotypes. p values are from the analysis of covariance (ANCOVA) showing difference between group means after adjusting for the confounding effects of age, gender, and BMI. Serum Mfge8 measures were available in 78 subjects including 39 T2DM cases and age- and gender-matched 39 controls
