Optimization of pCMV3-Nog-C-GFP Spark electrotransfection in MCF-7, a breast cancer cell line

خلاصه انگلیسی

Bone morphogenetic protein (BMP) signaling is known as one of the most important pathways in breast cancer tumorigenesis. This triggers the epithelial to mesenchymal transition (EMT) in metastatic cells and consequently the migrating cells become invasive and noggin, a BMP antagonist prevents it. So, the present study aimed to optimize Noggin transfection into MCF-7 as a breast cancer cell line. Following DH5α bacterial cell culturing and pCMV3- Nog-GFPSpark transformation, the resulted plasmid was extracted, purified and finally transfected into MCF-7 at different voltages (100-230V), resistances (1000 and ∞ Ω) and capacitances (25-75μF) using the electroporation system with various concentrations of plasmid (between 30 and 100μg/ml). As a result, we found that noggin has a better transfection into MCF- 7 in 230V, 50μF, 1000 Ωof electroporator. At 80μg/ml concentration of plasmid, the cell expressing GFP also represented the noggin expression
