Abstract

Breast cancer is the most common malignancy and the leading cause of cancer-related death among women
worldwide. The underlying mechanisms for breast cancer development, especially in young women, are not completely
understood. Although there are several experimental models to understand the biology of breast cancer such as
immortalized cell lines, many of these cell lines have been in culture for decades and most of them have been derived
from Caucasians or African-Americans. So, it is required to establish a new cell line derived from primary tumors and
Asian women. In this study Pari-Institute for Cancer Research (Pari-ICR) was derived from the primary breast tumor
of a 36-years old patient with invasive ductal carcinoma. We characterized the cell line by examining morphology,
expression of different markers, and functional profile. Immunocytochemistry showed that this cell line does not express
estrogen and progesterone receptors as well as human epidermal growth factor receptor 2 (HER2). Pari-ICR cell line
expresses high levels of Vimentin, Ezrin, and S100 but does not express EpCAM, Cytokeratin19, Pan-cytokeratin,
Nestin, and Desmin. Its doubling time of Pari-ICR was about 22h and was able to grow as colonies in soft agar. It
displayed a higher ability of migration and invasion in comparison with MCF-7 cell line. This breast cancer cell line
can serve as a model for understanding the molecular mechanisms of breast carcinogenesis. Moreover, it can be used
as an appropriate resource to find novel biomarkers or assess new drugs.
