Biochem/physiol Actions

Lapatinib acts as a dual tyrosine kinase inhibitor of epidermal growth factor receptor (EGFR/ErbB1) and human epidermal growth factor receptor 2 (HER2/ErbB2). It competes for its binding site on the tyrosine kinase domain with adenosine triphosphate (ATP). Lapatinib mediates has been studied in vitro in the inhibition of cell growth as well as and apoptosis induction in several human cancer cells such as breast, lung, vulva, gastric, and head and neck cancer.

HER-2 belongs to the human epidermal growth factor receptor (HER) family. Via different signal transduction pathways, HER-2 regulates normal cell proliferation, survival, and differentiation. Recently, it was reported that MCF10A, BT474, and MDA-MB-231 cells bearing the HER2 K753E mutation were

Recent clinical data indicates that the emergence of mutant drug-resistant kinase alleles may be particularly relevant for targeted kinase inhibitors. In order to explore how different classes of targeted therapies impact upon resistance mutations, we performed EGFR (epidermal-growth-factor receptor) resistance
