Vascular smooth muscle cells (SMCs) are key components in our blood vessels, and show remarkable plasticity. SMCs are normally growth-quiescent in the normal adult vessels, but are activated by injury, or exposure to growth factors, such as fibroblast growth factor-2 (FGF-2) and pro-inflammatory cytokines, such as interleukin-1beta (IL-1beta). These cues are sensed by these cells through changes in immediate-early gene expression, and can lead to increased proliferation and migration. These responses are associated with the initiation and progression of a range of vascular diseases including atherosclerosis, post-angioplasty restenosis and bypass graft stenosis. |

We provided total RNA (in triplicate) from growth arrested human aortic SMCs (Cell Applications) treated with IL-1beta or FGF-2 for periods of up to 6 hours. SMCs (pool of 3 donors) were grown in 100 mm petri dishes in Waymouth’s medium, pH 7.4, supplemented with 1 mM L-glutamine, 10 units/ml penicillin, 10 mcg/ml streptomycin and 10% fetal bovine serum, at 37°C in a humidified atmosphere of 5% CO2. The cells were rendered growth-quiescent at 80-90% confluency by incubation in serum-free medium for 24h. The SMCs were then exposed to IL-1beta (10ng/ml) or FGF-2 (50ng/ml) for various times up to 6 hours (0, 15, 30, 45, 60, 120, 180, 240, 300 and 360 min). 0 min samples represent growth arrested and unstimulated cells. RNA was harvested using TRIzol reagent, quantitated using a Nanodrop spectrophometer and validated for the transient induction of Egr-1 mRNA (by quantitative real-time PCR) prior to shipment to the Omics Science Center, RIKEN Yokohama Institute (Japan) for CAGE analysis. |

Early growth response-1 (Egr-1) is an immediate-early gene (encoding a zinc finger transcription factor) that is poorly expressed in growth-quiescent cells and serves as a marker of cell activation or stress. Total RNA provided to the RIKEN Yokohama Institute was first analysed for Egr-1 expression by qRT-PCR. This demonstrated peak inducible expression after 30 min by FGF-2 and after 60 min by IL-1beta (Fig 1). Transient expression of this biomarker within 30-60 min is supported by the literature (e.g. Zhu et al. 2007). |
