Figure 3. Cell Viability and Reduction of GAPDH Gene Expression in Several Cell Types. Successful gene silencing and high cell viability was achieved in 11 primary cell types and 3 hard-to-transfect immortalized cell lines: Primary Cells: human mesenchymal stem cells (hMSC), normal human astrocyte cells (NHA), normal human dermal fibroblasts-neonatal (NHDF-Neo), rat astrocytes (DI TNC1), normal human umbilical vein endothelial cells (HUVEC), bovine aortic endothelial cells (BAEC), bovine aortic vascular smooth muscle cells (BAVSMC), bovine adrenal microvascular endothelial cells (BAMEC), mouse embryo fibroblast (MEF), rhesus monkey stem cells (RMSC), bovine lung microvascular endothelial cells (BLMVEC) are shown in blue. Hard-to-transfect cell lines: Jurkat (human acute T-cells), K562 (human erythroleukemia cells), PC12 (rat pheochromocytoma cells) are shown in black.
siRNA targeting GAPDH or a negative control siRNA (1.5 g) were electroporated. 48 hours after transfection, the cells were harvested and analyzed by real time RT-PCR for gene expression levels. 18S rRNA levels were used to normalize GAPDH expression. Remaining gene expression was calculated as a percentage of gene expression compared with the negative control siRNA.
