Lapatinib 66-75 tumor protein p53 Homo sapiens 117-120 27791982-0 2017 ErbB2 inhibition by lapatinib promotes degradation of mutant p53 protein in cancer cells. Lapatinib 20-29 tumor protein p53 Homo sapiens 61-64 27791982-5 2017 Here we report that pharmacological interception of this circuit by ErbB2 inhibitor lapatinib downregulates mutant p53 in vitro and in vivo. Lapatinib 84-93 tumor protein p53 Homo sapiens 115-118 27791982-6 2017 We found that ErbB2 inhibition by lapatinib inhibits transcription factor HSF1, and its target Hsp90, followed by mutant p53 degradation in MDM2 dependent manner. Lapatinib 34-43 tumor protein p53 Homo sapiens 121-124 27791982-7 2017 Thus, our data suggest that mutant p53 sensitizes cancer cells to lapatinib via two complementary mechanisms: mutant p53 mediated amplification of ErbB2 signaling, and simultaneous annihilation of both potent oncogenic drivers, ErbB2 and mutant p53. Lapatinib 66-75 tumor protein p53 Homo sapiens 35-38 27791982-7 2017 Thus, our data suggest that mutant p53 sensitizes cancer cells to lapatinib via two complementary mechanisms: mutant p53 mediated amplification of ErbB2 signaling, and simultaneous annihilation of both potent oncogenic drivers, ErbB2 and mutant p53. Lapatinib 66-75 tumor protein p53 Homo sapiens 117-120 23652204-8 2013 MDM2 inhibition overcame lapatinib resistance in cells with either wild-type or mutant p53 and in xenograft models. Lapatinib 25-34 tumor protein p53 Homo sapiens 87-90 27611952-3 2016 TP53 status was correlated to response to neoadjuvant anthracycline/taxane-based chemotherapy with or without carboplatin and trastuzumab/lapatinib in HER2-positive and bevacizumab in TNBC. Lapatinib 138-147 tumor protein p53 Homo sapiens 0-4 27659302-5 2016 This high-throughput western blot approach allowed us to identify and characterize alterations in cellular signal transduction that occur during the development of resistance to the kinase inhibitor Lapatinib, revealing major changes in the activation state of Ephrin-mediated signalling and a central role for p53-controlled processes. Lapatinib 199-208 tumor protein p53 Homo sapiens 311-314 32988919-7 2020 CONCLUSION: Mutations in TP53 and PIK3CA hotspot at exon 9 may be potential negative predictors of ER+HER2+ BC treated with neoadjuvant letrozole and lapatinib, while MLL2 inactivating mutation might confer therapeutic benefit in these patients. Lapatinib 150-159 tumor protein p53 Homo sapiens 25-29 19287975-7 2009 In RT112 cells, which express high levels of ErbB receptors and harbour wild-type p53, combined GTC/lapatinib treatment resulted in the phosphorylation of p53 at Ser46 and accumulation of sub-G1 cell populations. Lapatinib 100-109 tumor protein p53 Homo sapiens 82-85 19287975-7 2009 In RT112 cells, which express high levels of ErbB receptors and harbour wild-type p53, combined GTC/lapatinib treatment resulted in the phosphorylation of p53 at Ser46 and accumulation of sub-G1 cell populations. Lapatinib 100-109 tumor protein p53 Homo sapiens 155-158 18212337-10 2008 Within cohort A, phosphorylated (p) HER-3 and lack of p53 expression predicted for response to lapatinib (P < .05). Lapatinib 95-104 tumor protein p53 Homo sapiens 54-57 31234033-6 2019 Alternatively, lapatinib amplified signals of TP53 gene effectively by raising the concentration. Lapatinib 15-24 tumor protein p53 Homo sapiens 46-50 30743996-6 2019 Restoring wild type p53 activity either by transfection or by treatment with APR-246, a molecule which reactivates mutant p53, blocked lapatinib-induced senescence and caused increased cell death. Lapatinib 135-144 tumor protein p53 Homo sapiens 20-23 30743996-6 2019 Restoring wild type p53 activity either by transfection or by treatment with APR-246, a molecule which reactivates mutant p53, blocked lapatinib-induced senescence and caused increased cell death.
