Due to the apparent lack of Kardiotoxizit t lapatinib may be useful in combination therapy with anthracyclines. A phase I study of lapatinib with epirubicin is currently underway to determine the dose s Re of epirubicin in combination with lapatinib and examine the Kardiotoxizit t this combination. Several big e randomized clinical trials are currently underway to assess the beneficial treatment for cancer of early stage breast cancer lapatinib.

HER2 amplification leads to an increase of HER2 in the surface of the cell surface by aberrant signaling homo and heterodimers with HER2. HER2 oncogenic properties are likely the result of increased Hten activation of downstream signaling pathways of HER2 protein. In particular, Ras signaling through MAPK cascade is responsible for cell proliferation, migration and angiogenesis, w While the phosphoinositide 3-kinase Akt exerts several anti-apoptotic and wachstumsf Rdernde effects. HER2 targeted therapies, such as the monoclonal antibodies Body trastuzumab and lapatinib HER2/EGFR dual tyrosine kinase inhibitor can be applied successfully to treat patients with HER2.<br> In addition, recent data suggest that these drugs k Also nnten applications in various cancers on histology. However, the effectiveness of the fight against the HER2 therapy at a fraction of patients Descr Nkt, and even those who initially Highest respond to treatment, acquired resistance is h Observed frequently. Chronic exposure to inhibitors of protein relative to cellular Re adaptations with the potential to reduce the effectiveness of these drugs. Sergina et al. describes a feedback mechanism controlled controlled by an act which leads to inhibition of Akt in response to HER-2 tyrosine kinase inhibitors lead to a redistribution of the cell membrane to maintain HER3 and HER3 phosphorylation. HER3 signaling would be increased again Hen, and then restore Akt activity t, leading to drug resistance.<br> Similarly, L Ngere inhibition of Akt in lapatinib-treated cells was shown that FOXO3a, a transcription factor, signal transduction from Suppress estrogen regulated. Consequently, breast cancer cells that survive before for HER2 signaling for the base, is supported by the activity T the state of emergency and escape cell death as a consequence of the inhibition of HER2. Closing Lich acquired resistance to trastuzumab in an experimental model was correlated with an increased Hten EGFR, EGF, TGF has layers, and heregulin. Overall, the scientific journal PLoS ONE | Published in PloSOne first February 2010 | Volume 5 | Issue 2 | E9024 ndnis Gain a detailed molecular consequences of inhibiting HER2 appears to be essential for therapeutic strategies to overcome resistance and improve clinical outcomes. Here, we used low-density arrays to evaluate the Fa What is, and the inhibition of tyrosine kinase HER2 with lapatinib would ask influence the expression of a number of genes involved in metastatic breast cancer biology. We show that lapatinib rapid upregulation of Grb7, an adapter protein that is usually caused by coamplified
