To understand the significance of TALAM1 in human breast cancer, we first determined the expression levels of both MALAT1 and TALAM1 in different human breast cancer cell lines (MCF7 – Luminal A ER+/PR+, MDA-MB-231 (named hereafter as MDA-231) – Triple negative [mesenchymal features]) [15, 16], and a control non-tumorigenic epithelial breast cell (MCF10A cells). The gene discussed is MALAT1; the disease is breast cancer.
