SK-BR3 Cell Line:
SK-BR-3 is a breast cancer cell line that was derived from a metastatic tumor of a 43-year-old Caucasian female patient. The SK-BR-3 cell line is known to overexpress the human epidermal growth factor receptor 2 (HER2/neu) protein, which is a hallmark of approximately 20-25% of breast cancers. The SK-BR-3 cell line is commonly used in cancer research to study the mechanisms of HER2/neu-driven breast cancer and to develop new treatments for HER2-positive breast cancer. In particular, the SK-BR-3 cell line has been used to investigate the effectiveness of drugs that target the HER2 receptor, such as trastuzumab (Herceptin) and lapatinib (Tykerb). In addition to breast cancer research, the SK-BR-3 cell line has been used in studies on the molecular mechanisms of cancer metastasis and drug resistance. Breast cancer is considered the most common malignancy in females as well as a significant public health issue. The SK-BR-3 tumorigenic cell line was established in 1970 by G. Trempe and L. J. Old from the mammary gland of a 43-year-old Caucasian female with breast adenocarcinoma. The SK-BR-3 cells were derived from a metastatic site by pleural effusion. Many of these tumorigenic cells exhibit polyploidy or an increased number of chromosomes. The SK-BR-3 cell line is considered a hypertriploid cell line with a very complex chromosome composition. The HER2/c-erb-2 gene product is overexpressed, and the modal chromosome number of 84 occurs in approximately 34% of cells. The SK-BR-3 cell line includes microvilli and desmosomes as well as glycogen granules. The SK-BR3 cell line is useful for studying antibody resistance in some breast cancer cells. Altogen Biosystems provides high-efficiency transfection kits for this cell line.
Cell line mutations:
Figure 1. Cyclophilin B silencing efficiency was determined by qRT-PCR in the SKBR3 cells transfected by Cyclophilin B siRNA or non-silencing siRNA control following the recommended transfection protocol. Cyclophilin mRNA expression levels were measured 48 hours post-transfection. 18S rRNA levels were used to normalize the Cyclophilin B data. Values are normalized to untreated sample. Data are presented as means ± SD (n=6).
Figure 2. Protein expression of Cyclophilin B in SK-BR-3 cells. DNA plasmid expressing Cyclophilin B or siRNA targeting Cyclophilin B were transfected into SK-BR-3 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.
