HCC1954 Cells

The HCC1954 cell line is derived from the primary ductal carcinoma of a human adult breast cancer patient. This cell line is prominently used in breast cancer research, especially for investigating the genetic and molecular characteristics of HER2-positive (HER2+) and triple-negative breast cancers. HCC1954 cells are HER2-overexpressing and possess mutations in the PIK3CA gene, making them a valuable model for studying the signaling pathways involved in cancer progression and the development of targeted therapies. HCC1954 cells exhibit an epithelial morphology and are known for their aggressive growth characteristics both in vitro and in vivo. They express markers associated with aggressive breast cancer phenotypes, including HER2/neu, but lack expression of estrogen receptor (ER) and progesterone receptor (PR), classifying them as triple-negative breast cancer cells. This cell line is extensively used to evaluate the efficacy and mechanisms of action of HER2-targeted therapies, such as trastuzumab, as well as novel PI3K inhibitors. Additionally, HCC1954 cells are employed in research focused on identifying biomarkers for drug resistance and exploring combination treatment strategies to enhance therapeutic outcomes. Their relevance in understanding the biology of aggressive breast cancer and in the development of effective treatments highlights the significance of the HCC1954 cell line in oncological research.
