NR4A2 induces expression of genes involved in synovial hyperplasia and inflammation. A. K4IM human synoviocytes were transduced in triplicate with lentiviral particles containing control empty or CMV-NR4A2 expression vectors. RNA was harvested after 48 hours and NR4A2 expression was measured by RT-qPCR using GAPDH as a control. ***p < 0.001. B. Pooled triplicate cDNA from the same experiment was analyzed on TaqMan Human Angiogenesis qPCR arrays. Gene expression data was normalized to 4 housekeeping genes and the genes most highly induced by NR4A2 are displayed.
