DU145 Cell Line:

According to American Cancer Society, over 161,000 men are estimated to be diagnosed with prostate cancer by the end of 2017. It is the third primary cause of male cancer deaths, in the United States. Prostate cancer is the most prevalent cancer especially in older males and can be successfully cured if diagnosed early. However, when it has spread to other parts of the body, more complicated treatment is required. The DU-145 prostate cancer cell line comprises androgen independent cells with a moderate ability to metastasize. The DU-145 cell line was established from human prostate cancer cells. These cells exhibit an epithelial cell morphology and possess metastatic potential. DU-145 cells are commonly used, along with PC3 cell line, in the study of prostate cancer, which affects many people (mainly men over the age of 50). This cell line is considered one of the “classical” prostate cancer cell lines. These cells are not sensitive to hormones and fail to express prostate-specific antigen (PSA). DU-145 cells are epithelial-like adherent cells growing as monolayers. The DU-145 line is not measurably hormone sensitive. It is only weakly positive for acid phosphatase, and isolated cells form colonies in soft agar. Analyses of the cell line have revealed microvilli, tonofilaments, and desmosomes. DU-145 do not express prostate antigen but do express functional receptor activator of NF-kappaB and androgen receptor. It has been shown glucosamine suppresses proliferation of DU-145. Transfection studies carried out using established cell lines significantly aid cancer research. Altogen Biosystems offers efficient lipid-based transfection reagent kits for the DU-145 prostate cancer cell line.

Data:

Figure 1. siRNAs targeting Lamin A/C mRNA or non-silencing control siRNA were transfected into DU-145 cells following the recommended protocol. At 48 hours post-transfection the cells were analyzed by qRT-PCR for Lamin A/C gene expression levels. 18S rRNA levels were used to normalize the Lamin A/C data. Values are normalized to untreated sample. Data are means ± SD (n=4).

Figure 2. Protein expression of Lamin A/C in DU145 cells. DNA plasmid expressing Lamin A/C or siRNA targeting Lamin A/C were transfected into DU145 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.
