Lapatinib 31-40 interferon alpha inducible protein 27 Homo sapiens 90-93 23907131-3 2013 However, the regulation of p27 in lapatinib-induced cell cycle arrest is not well studied. Lapatinib 34-43 interferon alpha inducible protein 27 Homo sapiens 27-30 23907131-4 2013 Here we demonstrate that lapatinib-induced cell growth inhibition and G1 cell cycle arrest in HER2-overexpressing human breast cancer cells were dependent on p27. Lapatinib 25-34 erb-b2 receptor tyrosine kinase 2 Homo sapiens 94-98 23907131-4 2013 Here we demonstrate that lapatinib-induced cell growth inhibition and G1 cell cycle arrest in HER2-overexpressing human breast cancer cells were dependent on p27. Lapatinib 25-34 interferon alpha inducible protein 27 Homo sapiens 158-161 23907131-5 2013 We also show that lapatinib-induced upregulation of p27 expression was mediated through both transcriptional and post-translational mechanisms.

Lapatinib 19-28 interferon alpha inducible protein 27 Homo sapiens 155-158 23907131-8 2013 Interestingly, we found that ERbeta1 but not ERbeta2 expression also upregulated p27 and enhanced lapatinib-induced cell proliferation inhibition and G1 cell cycle arrest in HER2-overexpressing breast cancer cells. Lapatinib 98-107 erb-b2 receptor tyrosine kinase 2 Homo sapiens 174-178 23907131-9 2013 Taken together, our results suggest that lapatinib induces p27 expression via both transcriptional and post-translational upregulations, leading to cell cycle arrest and cell proliferation inhibition, and that its effect on breast cancer cells may be modified by ER expression status.

Lapatinib 0-9 erb-b2 receptor tyrosine kinase 2 Homo sapiens 107-111 23708506-8 2013 Lapatinib in combination with 5-FU had more potent antitumor effects in the primary ESCC xenograft model, and markedly reduced the phosphorylation of EGFR and HER2, compared with lapatinib alone or in combination with oxaliplatin. Lapatinib 0-9 epidermal growth factor receptor Homo sapiens 150-154 23708506-8 2013 Lapatinib in combination with 5-FU had more potent antitumor effects in the primary ESCC xenograft model, and markedly reduced the phosphorylation of EGFR and HER2, compared with lapatinib alone or in combination with oxaliplatin. Lapatinib 0-9 erb-b2 receptor tyrosine kinase 2 Homo sapiens 159-163 23708506-9 2013 These data indicate that lapatinib has activity in EGFR- and/or HER2-expressing ESCC primary cells, and that lapatinib in combination with 5-FU may be a promising treatment strategy for patients with ESCC. Lapatinib 25-34 epidermal growth factor receptor Homo sapiens 51-55 23708506-9 2013 These data indicate that lapatinib has activity in EGFR- and/or HER2-expressing ESCC primary cells, and that lapatinib in combination with 5-FU may be a promising treatment strategy for patients with ESCC. Lapatinib 25-34 erb-b2 receptor tyrosine kinase 2 Homo sapiens 64-68 23816254-11 2013 CONCLUSIONS: In these HER2-expressing cell line models, lapatinib, neratinib, afatinib and trastuzumab treatment generated a characteristic and specific gene expression response, proportionate to the sensitivity of the cell lines to the HER2 inhibitor.Characterisation of the induced changes in expression levels of these genes may therefore give a valuable, very early predictor of the likely extent and specificity of tumour HER2 inhibitor response in patients, potentially guiding more specific use of these agents.

Lapatinib 60-69 BCL2 like 11 Homo sapiens 46-49 21499301-6 2011 The pro-apoptotic effect of lapatinib was less pronounced in cells with a PIK3CA mutation than in those without one.

Lapatinib 83-92 epidermal growth factor receptor Homo sapiens 109-116 20406946-4 2010 In the present study, using a clonal population of GW583340 (lapatinib analogue, ErbB1/2 inhibitor)-resistant IBC cells, we identified the overexpression of an antiapoptotic protein, X-linked inhibitor of apoptosis protein (XIAP), in acquired resistance to GW583340 in both ErbB2-overexpressing SUM190 and ErbB1-activated SUM149 cell lines derived from primary IBC tumors.

Lapatinib 61-70 erb-b2 receptor tyrosine kinase 2 Homo sapiens 274-279 20406946-4 2010 In the present study, using a clonal population of GW583340 (lapatinib analogue, ErbB1/2 inhibitor)-resistant IBC cells, we identified the overexpression of an antiapoptotic protein, X-linked inhibitor of apoptosis protein (XIAP), in acquired resistance to GW583340 in both ErbB2-overexpressing SUM190 and ErbB1-activated SUM149 cell lines derived from primary IBC tumors. Lapatinib 61-70 epidermal growth factor receptor Homo sapiens 81-86 20424000-3 2010 We have now investigated the effects of combination treatment with the oral fluoropyrimidine S-1 and the HER2-targeting agents lapatinib or trastuzumab in gastric cancer cells with or without HER2 amplification. Lapatinib 127-136 erb-b2 receptor tyrosine kinase 2 Homo sapiens 105-109 20424000-6 2010 Lapatinib or trastuzumab also induced downregulation of thymidylate synthase (TS) expression and activity only in cells with HER2 amplification.

Lapatinib 0-9 erb-b2 receptor tyrosine kinase 2 Homo sapiens 125-129 20424000-8 2010 These observations thus suggest that lapatinib-induced or trastuzumab-induced downregulation of TS is responsible, at least in part, for the synergistic antitumor effect of combined treatment with 5FU and HER2-targeting agents. Lapatinib 37-46 erb-b2 receptor tyrosine kinase 2 Homo sapiens 205-209 20064507-4 2010 With this, intense efforts have been made to inhibit the activity of the EGFR and HER2 by designing antibodies against the ligand binding domains (cetuximab, panitumumab and trastuzumab) or small molecules against the tyrosine kinase domains (erlotinib, gefitinib, and lapatinib).

Lapatinib 34-43 AKT serine/threonine kinase 1 Homo sapiens 102-105 20179222-10 2010 Cell cycle analysis revealed that lapatinib induced G(1) arrest in sensitive lines and phosphorylated AKT and phosphorylated ERK were decreased in response to lapatinib as well. Lapatinib 34-43 mitogen-activated protein kinase 1 Homo sapiens 125-128 20179222-10 2010 Cell cycle analysis revealed that lapatinib induced G(1) arrest in sensitive lines and phosphorylated AKT and phosphorylated ERK were decreased in response to lapatinib as well. Lapatinib 159-168 AKT serine/threonine kinase 1 Homo sapiens 102-105 20179222-10 2010 Cell cycle analysis revealed that lapatinib induced G(1) arrest in sensitive lines and phosphorylated AKT and phosphorylated ERK were decreased in response to lapatinib as well. Lapatinib 159-168 mitogen-activated protein kinase 1 Homo sapiens 125-128 20179222-14 2010 CONCLUSION: Together, these data suggest that lapatinib has activity in HER2-amplified upper gastrointestinal cancer and supports the ongoing clinical investigation of lapatinib in patients with HER2-amplified disease. Lapatinib 46-55 erb-b2 receptor tyrosine kinase 2 Homo sapiens 72-76 20179226-0 2010 Lapatinib restores hormone sensitivity with differential effects on estrogen receptor signaling in cell models of human epidermal growth factor receptor 2-negative breast cancer with acquired endocrine resistance. Lapatinib 0-9 erb-b2 receptor tyrosine kinase 2 Homo sapiens 120-154 20179226-2 2010 We investigated (a) whether the epidermal growth factor receptor/HER2 inhibitor lapatinib could restore endocrine responsiveness in cell models of acquired endocrine resistance with modest increases in HER2, and (b) the nature of ERalpha-HER2 cross-talk in this process. Lapatinib 80-89 erb-b2 receptor tyrosine kinase 2 Homo sapiens 65-69 20179226-6 2010 The effect of lapatinib on ERalpha signaling varied markedly depending on the nature of the HER2/ERalpha cross-talk. Lapatinib 14-23 estrogen receptor 1 Homo sapiens 27-34 20179226-6 2010 The effect of lapatinib on ERalpha signaling varied markedly depending on the nature of the HER2/ERalpha cross-talk. Lapatinib 14-23 erb-b2 receptor tyrosine kinase 2 Homo sapiens 92-96 20088787-0 2010 Ras-induced resistance to lapatinib is overcome by MEK inhibition. Lapatinib 26-35 mitogen-activated protein kinase kinase 7 Homo sapiens 51-54 20088787-1 2010 Lapatinib, a dual HER2 and EGFR tyrosine kinase inhibitor is highly active in HER2+ breast cancer. Lapatinib 0-9 erb-b2 receptor tyrosine kinase 2 Homo sapiens 18-22 20088787-1 2010 Lapatinib, a dual HER2 and EGFR tyrosine kinase inhibitor is highly active in HER2+ breast cancer. Lapatinib 0-9 erb-b2 receptor tyrosine kinase 2 Homo sapiens 78-82 20088787-5 2010 Using SKBR3 cells, a HER2+ breast cancer cell line that is naturally devoid of mutations in PI3KCA, PTEN, BRAF, and ras we show that both H-ras overexpression and expression of an oncogenic ras allele (ras V12) reduce susceptibility to lapatinib in analogy to what observed with activating PI3KCA mutations and with a constitutively active form of Akt. Lapatinib 236-245 Harvey rat sarcoma virus oncogene Mus musculus 138-143 20088787-6 2010 Importantly, we found that resistance to lapatinib due to ras overexpression or to ras V12 is overcome by MEK inhibition with U0126, suggesting a key role for the MEK-Erk pathway in ras-induced resistance. Lapatinib 41-50 mitogen-activated protein kinase kinase 7 Homo sapiens 106-109 20088787-6 2010 Importantly, we found that resistance to lapatinib due to ras overexpression or to ras V12 is overcome by MEK inhibition with U0126, suggesting a key role for the MEK-Erk pathway in ras-induced resistance. Lapatinib 41-50 mitogen-activated protein kinase kinase 7 Homo sapiens 163-166 20088787-6 2010 Importantly, we found that resistance to lapatinib due to ras overexpression or to ras V12 is overcome by MEK inhibition with U0126, suggesting a key role for the MEK-Erk pathway in ras-induced resistance. Lapatinib 41-50 EPH receptor B2 Homo sapiens 167-170 20088787-9 2010 Combining MEK inhibitors with lapatinib may help overcome this form of resistance and increase the efficacy of lapatinib in these tumors. Lapatinib 111-120 mitogen-activated protein kinase kinase 7 Homo sapiens 10-13 20179241-2 2010 Interruption of HER2/ER cross-talk with lapatinib can restore sensitivity to anti-estrogens and thus, should be investigated in combination with endocrine therapy in patients with ER+/HER2-negative breast cancers. Lapatinib 40-49 estrogen receptor 1 Homo sapiens 21-23 20179241-2 2010 Interruption of HER2/ER cross-talk with lapatinib can restore sensitivity to anti-estrogens and thus, should be investigated in combination with endocrine therapy in patients with ER+/HER2-negative breast cancers. Lapatinib 40-49 erb-b2 receptor tyrosine kinase 2 Homo sapiens 184-188 20179226-7 2010 In long-term estrogen-deprived cells characterized by enhanced ERalpha function, lapatinib suppressed ERalpha genomic activity (as measured by pERSer118, ERalpha transcriptional activity, and PGR gene expression). Lapatinib 81-90 estrogen receptor 1 Homo sapiens 102-109 20179226-7 2010 In long-term estrogen-deprived cells characterized by enhanced ERalpha function, lapatinib suppressed ERalpha genomic activity (as measured by pERSer118, ERalpha transcriptional activity, and PGR gene expression). Lapatinib 81-90 estrogen receptor 1 Homo sapiens 102-109 20179226-7 2010 In long-term estrogen-deprived cells characterized by enhanced ERalpha function, lapatinib suppressed ERalpha genomic activity (as measured by pERSer118, ERalpha transcriptional activity, and PGR gene expression). Lapatinib 81-90 progesterone receptor Homo sapiens 192-195 20179226-8 2010 In contrast, in long-term tamoxifen-treated cells with reduced ERalpha activation, lapatinib reactivated ERalpha genomic function. Lapatinib 83-92 estrogen receptor 1 Homo sapiens 105-112 20179226-11 2010 Regardless, interrupting the HER2/ERalpha cross-talk with lapatinib can restore endocrine sensitivity and should be investigated as a therapeutic strategy in combination with endocrine therapy in ERalpha+/HER2- patients with acquired endocrine resistance. Lapatinib 58-67 erb-b2 receptor tyrosine kinase 2 Homo sapiens 29-33 20179226-11 2010 Regardless, interrupting the HER2/ERalpha cross-talk with lapatinib can restore endocrine sensitivity and should be investigated as a therapeutic strategy in combination with endocrine therapy in ERalpha+/HER2- patients with acquired endocrine resistance. Lapatinib 58-67 erb-b2 receptor tyrosine kinase 2 Homo sapiens 205-209 20124187-0 2010 Randomized study of Lapatinib alone or in combination with trastuzumab in women with ErbB2-positive, trastuzumab-refractory metastatic breast cancer. Lapatinib 20-29 erb-b2 receptor tyrosine kinase 2 Homo sapiens 85-90 20124187-1 2010 PURPOSE: Preclinical studies in ErbB2-positive cell lines demonstrated a synergistic interaction between lapatinib and trastuzumab, suggesting that dual blockade is more effective than a single agent alone. Lapatinib 105-114 erb-b2 receptor tyrosine kinase 2 Homo sapiens 32-37 20124187-11 2010 CONCLUSION: Despite disease progression on prior trastuzumab-based therapy, lapatinib in combination with trastuzumab significantly improved PFS and CBR versus lapatinib alone, thus offering a chemotherapy-free option with an acceptable safety profile to patients with ErbB2-positive MBC. Lapatinib 76-85 carbonyl reductase 1 Homo sapiens 149-152 20124187-11 2010 CONCLUSION: Despite disease progression on prior trastuzumab-based therapy, lapatinib in combination with trastuzumab significantly improved PFS and CBR versus lapatinib alone, thus offering a chemotherapy-free option with an acceptable safety profile to patients with ErbB2-positive MBC. Lapatinib 76-85 erb-b2 receptor tyrosine kinase 2 Homo sapiens 269-274 20126311-1 2010 The efficacy of anti-HER2 therapeutics, such as lapatinib and trastuzumab, is limited by primary and acquired resistance. Lapatinib 48-57 erb-b2 receptor tyrosine kinase 2 Homo sapiens 21-25 20174688-6 2010 Using our SILAC approach with non-dialyzed serum, we successfully quantified the phosphoproteome of MCF-7 cells induced by lapatinib, an EGFR1/Her2 dual kinase inhibitor. Lapatinib 123-132 erb-b2 receptor tyrosine kinase 2 Homo sapiens 143-147 20126311-3 2010 Here, we used low-density arrays, quantitative PCR, and western blotting to determine how HER2 signaling inhibition with lapatinib or PI3K inhibitors affects the expression of genes involved in breast cancer metastatic spread and overall prognosis. Lapatinib 121-130 erb-b2 receptor tyrosine kinase 2 Homo sapiens 90-94 20126311-7 2010 We found that lapatinib induces upregulation of Grb7, an adaptor protein involved in receptor tyrosine kinase signaling and promoting cell survival and cell migration. Lapatinib 14-23 growth factor receptor bound protein 7 Homo sapiens 48-52 20126311-8 2010 Grb7 upregulation induced by lapatinib was found to occur in cancer cells in vitro and in vivo. Lapatinib 29-38 growth factor receptor bound protein 7 Homo sapiens 0-4 20126311-10 2010 Thus, Grb7 is repressed by PI3K signaling and lapatinib-mediated Akt inhibition is responsible for Grb7 de-repression. Lapatinib 46-55 AKT serine/threonine kinase 1 Homo sapiens 65-68 20126311-10 2010 Thus, Grb7 is repressed by PI3K signaling and lapatinib-mediated Akt inhibition is responsible for Grb7 de-repression.
