Article Title: Cited2 modulates hypoxia-inducible factor-dependent expression of vascular endothelial growth factor in nucleus pulposus cells of the rat intervertebral disc.

doi: 10.1002/art.24073

Figure Lengend Snippet: Figure 6. Regulation of vascular endothelial growth factor (VEGF) expression by HIF and cited2. A, Real-time reverse transcription– polymerase chain reaction analysis of the relative expression levels of VEGF in normoxic and hypoxic nucleus pulposus cells. B, Nucleus pulposus cells were cotransfected with VEGF promoter plasmid along with 100 ng of either constitutively active (CA) HIF-2 plasmid (pCA-HIF-2) or pCA-HIF-1 (401603) plasmid or with empty backbone vector pcDNA3 together with 100 ng pARNT (HIF-1) plasmid. C, Nucleus pulposus cells were cotransfected with VEGF promoter plasmid along with increasing doses (100–300 ng) of dominant-negative HIF-1 plasmid (DN-HIF-1). Triangles indicate addition of increasing dose of plasmid. D, Nucleus pulposus cells were cotransfected with VEGF luciferase reporter along with either cited2 expression plasmid or empty backbone plasmid pCMV6 under nor- moxic conditions. E, Nucleus pulposus cells were cotransfected with cited2 reporter construct along with either cited2 small interfering RNA (siRNA) (Si-Cited2) or control siRNA duplexes (Co) and cultured under normoxic or hypoxic conditions for 24 hours. F, Relative expression of VEGF mRNA after partial silencing of cited2 under hypoxic conditions. Values are the mean and SD from 3 independent experiments performed in triplicate. P 0.05. See Figure 2 for other definitions.

Article Snippet: Cited2 expression plasmid (#SC116345) and plasmid pCMV6 were purchased from Origene (Rockville, MD).
