HARA-B Cells

The HARA-B cell line is derived from human squamous cell carcinoma of the lung, specifically established from metastatic bone tissue in a mouse model. This cell line is a secondary development from the original HARA cell line and is characterized by its high expression of parathyroid hormone-related protein (PTHrP), which plays a significant role in the extensive bone metastasis observed in these cells. The HARA-B line has been instrumental in studying the mechanisms of bone metastasis associated with lung cancer. Scientific studies involving HARA-B often focus on its utility in modeling hypercalcemia, a common paraneoplastic syndrome associated with certain cancers, including lung cancer. The hypercalcemia in this model is induced by hypodermic transplantation of the cells, providing a valuable tool for understanding the interactions between cancer cells and bone cells, as well as the pathways that lead to bone degradation and calcium release. This cell line helps researchers investigate potential therapeutic strategies to mitigate bone metastasis and associated complications in lung cancer patients.
