MCF-7 Cell Line:
MCF-7 (breast cancer cell line) was isolated from a 69-year-old Caucasian female in 1970. It is the best characterized and most widely used of all the human breast cancer cell lines. MCF-7 stands for Michigan Cancer Foundation – 7 (referring to the institute where in 1973 the cell line was discovered by Soule and associates). This cell line is a perfect model to study the pathway of malignant progression. Previous to MCF-7, there was no mammary cell line that could live longer than a few months. MCF-7 has multiple characteristics of differentiated mammary epithelium such as the capability of forming domes and the ability to process estradiol via cytoplasmic estrogen receptors. TNF alpha inhibits the growth of MCF-7 breast cancer cells. Applying anti-estrogens can transform the secretion of insulin-like growth factor binding proteins.
Figure 1. GAPD mRNA levels were quantified using real-time RT-PCR in the MCF-7 cells transfected with siRNAs targeting GAPD or non-silencing siRNA. Forty-eight hours post-transfection, the cells were harvested and analyzed by real-time RT-PCR for GAPDH mRNA expression levels. Data were normalized against the 18S rRNA signal. Control samples were either mock-transfected or untreated. Values are normalized to untreated sample. Data are means ± SD (n=3).
Figure 2. Protein expression of GAPDH in MCF-7 cells. DNA plasmid expressing GAPDH or siRNA targeting GAPDH were transfected into MCF-7 cells following Altogen Biosystems transfection protocol. At 72 hours post-transfection the cells were analyzed by Western Blot for protein expression levels (normalized by total protein, 10 µg of total protein loaded per each well). Untreated cells used as a negative control.
