Gremlin in the Vitreous of Patients with Proliferative Diabetic Retinopathy and the Downregulation of Gremlin in Retinal Pigment Epithelial Cells

Figure 5

Gremlin siRNA significantly downregulated the expression of gremlin in RPE cells under normal glucose conditions. The cells were transfected with siRNA for 24 h and then incubated in normal glucose for an additional 24 h. A real-time PCR analysis showed that the silence of gremlin significantly reduced the expression of gremlin in RPE cells. The data represent the of three independent experiments. versus 5.5 mM. GR represents gremlin; Con represents control.
