| Popis: | SKBR-3 cell line is a breast cancer model for human epidermal growth factor receptor2 (HER2) positive. Only 50% of patients of this type have fully responded to chemotherapy. Natrium iodide symporter expression correlates with the uptake and ability of cells to accumulate radioiodine. The aim of this study was to examine natrium/iodide symporter (NIS) expression and its distribution with and without epidermal growth factor (EGF) treatment using immunocytofluoresence (ICF). This study was conducted at the Cell Culture Laboratory, Faculty of Medicine, Universitas Padjadjaran from September 2013 to April 2014. SKBR3 cells were cultured until 70% confluent. Cells were then divided into two groups: treatment group and control group. The treatment group was treated with EGF 50 ng/mL. Cells were incubated with primary antibody rabbit polyclonal antibody anti-NIS, and then were followed with secondary-antibody goat polyclonal antibody to rabbit. Data from the observation were then assessed semi-quantitatively. Natrium/iodide symporter was seen to be expressed and distributed in the cytoplasm. Cells induced by EGF showed significant increase in NIS expression in cytoplasm and its distribution in cell membrane. It is concluded that the SKBR3 cells express NIS in cytoplasm and that EGF induction increases NIS expression and distribution in cell membrane. This finding leads to a potential ability of breast cancer cells to uptake and accumulate radioiodine. |
