Molecular function, biological processes and candidate regulatory transcription factors and microRNAs in normal mesangial cells. The central hexagons show some of the 172 genes with elevated expression in normal mesangial cells, compared to other cell types. The surrounding squares show color coded molecular functions (light green), biological processes (dark green), transcription factors (light purple) and microRNAs (dark purple), strongly associated with these genes. Lines show connections to linked genes. A. The cell adhesion biological process, with associated genes, is highlighted in yellow. B. The locomotion biological process and associated genes is highlighted in yellow. For complete lists of molecular functions, biological processes, transcription factors, microRNAs and other features see Additional file 3: Table S2.
