Detailed Summary

SUM44PE is a human breast cancer cell line established from invasive lobular carcinoma (ILC) and is notable for its E-cadherin deficiency, a hallmark of ILC. This cell line exhibits unique estrogen-mediated gene expression patterns and altered tamoxifen response, making it a valuable model for studying endocrine resistance in breast cancer. SUM44PE has been used in studies to characterize the molecular and phenotypic features of ILC, including its distinct growth patterns, anchorage-independent survival, and response to targeted therapies. Research on SUM44PE has contributed to understanding the role of E-cadherin loss in tumorigenesis and the identification of potential therapeutic targets in ILC.
