Could Hbx Protein Expression Affect Signal Pathway Inhibition by Gefitinib Or Selumetinib, a MEK Inhibitor, in Hepatocellular Carcinoma Cell Lines?
ORIGINAL ARTICLE Oncology & Hematology DOI: 10.3346/jkms.2011.26.2.214 • J Korean Med Sci 2011; 26: 214-221 Could HBx Protein Expression Affect Signal Pathway Inhibition by Gefitinib or Selumetinib, a MEK Inhibitor, in Hepatocellular Carcinoma Cell Lines? Yoon Kyung Park1, Kang Mo Kim1, Hepatitis B virus X (HBx) protein has been known to play an important role in development Young-Joo Lee2, Ki-Hun Kim2, of hepatocellular carcinoma (HCC). The aim of this study is to find out whether HBx Sung-Gyu Lee2, Danbi Lee1, protein expression affects antiproliferative effect of an epidermal growth factor receptor- Ju Hyun Shim1, Young-Suk Lim1, tyrosine kinase (EGFR-TK) inhibitor and a MEK inhibitor in HepG2 and Huh-7 cell lines. We 1 1 Han Chu Lee , Young-Hwa Chung , established HepG2 and Huh-7 cells transfected stably with HBx gene.

Barata1 & Matthew Cooney2 & Prateek Mendiratta 2 & Ruby Gupta3 & Robert Dreicer4 & Jorge A. Garcia3 Received: 25 September 2018 /Accepted: 16 October 2018 /Published online: 7 November 2018 # Springer Science+Business Media, LLC, part of Springer Nature 2018 Summary Background Mammalian target of rapamycin (mTOR) pathway and angiogenesis through vascular endothelial growth factor (VEGF) have been shown to play important roles in prostate cancer progression. Preclinical data in prostate cancer has suggested the potential additive effect dual inhibition of VEGF and mTOR pathways. In this phase I/II trial we assessed the safety and efficacy of bevacizumab in combination with temsirolimus for the treatment of men with metastatic castration-resistant prostate cancer (mCRPC). Methods In the phase I portion, eligible patients received temsirolimus (20 mg or 25 mg IV weekly) in combination with a fixed dose of IV bevacizumab (10 mg/kg every 2 weeks). The primary endpoint for the phase II portion was objective response measured by either PSA or RECIST criteria. Exploratory endpoints included changes in circulating tumor cells (CTC) and their correlation with PSA response to treatment. Results Twenty-one patients, median age 64 (53–82), with pre- treatment PSA of 205.3 (11.1–1801.0), previously treated with a median of 2 (0–5) lines of therapy for mCRPC received the combination of temsirolimus weekly at 20 mg (n =4)or25mg(n = 17) with bevacizumab 10 mg/kg every 2 weeks (n =21). -

MET Or NRAS Amplification Is an Acquired Resistance Mechanism to the Third-Generation EGFR Inhibitor Naquotinib
www.nature.com/scientificreports OPEN MET or NRAS amplifcation is an acquired resistance mechanism to the third-generation EGFR inhibitor Received: 5 October 2017 Accepted: 16 January 2018 naquotinib Published: xx xx xxxx Kiichiro Ninomiya1, Kadoaki Ohashi1,2, Go Makimoto1, Shuta Tomida3, Hisao Higo1, Hiroe Kayatani1, Takashi Ninomiya1, Toshio Kubo4, Eiki Ichihara2, Katsuyuki Hotta5, Masahiro Tabata4, Yoshinobu Maeda1 & Katsuyuki Kiura2 As a third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI), osimeritnib is the standard treatment for patients with non-small cell lung cancer harboring the EGFR T790M mutation; however, acquired resistance inevitably develops. Therefore, a next-generation treatment strategy is warranted in the osimertinib era. We investigated the mechanism of resistance to a novel EGFR-TKI, naquotinib, with the goal of developing a novel treatment strategy. We established multiple naquotinib-resistant cell lines or osimertinib-resistant cells, two of which were derived from EGFR-TKI-naïve cells; the others were derived from geftinib- or afatinib-resistant cells harboring EGFR T790M. We comprehensively analyzed the RNA kinome sequence, but no universal gene alterations were detected in naquotinib-resistant cells. Neuroblastoma RAS viral oncogene homolog (NRAS) amplifcation was detected in naquotinib-resistant cells derived from geftinib-resistant cells. The combination therapy of MEK inhibitors and naquotinib exhibited a highly benefcial efect in resistant cells with NRAS amplifcation, but the combination of MEK inhibitors and osimertinib had limited efects on naquotinib-resistant cells. Moreover, the combination of MEK inhibitors and naquotinib inhibited the growth of osimertinib-resistant cells, while the combination of MEK inhibitors and osimertinib had little efect on osimertinib-resistant cells. -

Associate Professor of Medicine, Department of Leukemia, University of Texas MD Anderson Cancer Center DOI: 10.17925/EOH.2010.04.0.43 Abstract Conventional chemotherapy for patients with relapsed/refractory acute myeloid leukaemia (AML) remains unsatisfactory, with median survival ranging from 18 weeks following first relapse to six weeks in those with a second or higher relapse. The only potentially curative therapy is stem cell transplantation. Duration of first complete remission (CR) is the best predictor of response to salvage therapy. Novel therapies directed against a number of molecular aberrations associated with AML are being developed, including anti-CD33 monoclonal antibodies, FMS-like tyrosine kinase (FLT3) inhibitors, nucleoside analogues, hypomethylating agents and histone deacetylatase inhibitors, among others. Clinical trials combining novel agents with conventional chemotherapy are of particular interest, and definition of dose, schedule and combination partners remains an area of intense research.

Here, we investigate BRAFV600E amplification events that underlie resistance to the MEK inhibitor selumetinib (AZD6244/ARRY-142886) in COLO205 cells. We find that de novo focal BRAF amplification is the primary path to resistance irrespective of pre-existing amplifications. Although selumetinib causes long-term G1 arrest, we observe that cells stochastically re-enter the cell cycle during treatment without reactivation of ERK1/2 or induction of a normal proliferative gene expression programme. Genes encoding DNA replication and repair factors are downregulated during G1 arrest, but many are transiently induced when cells escape arrest and enter S and G2. -

Dual Targeting of HER2-Positive Cancer with Trastuzumab Emtansine and Pertuzumab: Critical Role for Neuregulin Blockade in Antitumor Response to Combination Therapy

Albain9, Nadia Harbeck10, Veronique Dieras7, Diana Crivellari11, Liang Fang2, Ellie Guardino3, Steven R. Olsen3, Lisa M. Crocker4, and Mark X. Sliwkowski1 Abstract Purpose: Targeting HER2 with multiple HER2-directed therapies represents a promising area of treatment for HER2-positive cancers. We investigated combining the HER2-directed antibody–drug con- jugate trastuzumab emtansine (T-DM1) with the HER2 dimerization inhibitor pertuzumab (Perjeta). Experimental Design: Drug combination studies with T-DM1 and pertuzumab were performed on cultured tumor cells and in mouse xenograft models of HER2-amplified cancer. In patients with HER2- positive locally advanced or metastatic breast cancer (mBC), T-DM1 was dose-escalated with a fixed standard pertuzumab dose in a 3þ3 phase Ib/II study design. Results: Treatment of HER2-overexpressing tumor cells in vitro with T-DM1 plus pertuzumab resulted in synergistic inhibition of cell proliferation and induction of apoptotic cell death. The presence of the HER3 ligand, heregulin (NRG-1b), reduced the cytotoxic activity of T-DM1 in a subset of breast cancer lines; this effect was reversed by the addition of pertuzumab. Results from mouse xenograft models showed enhanced antitumor efficacy with T-DM1 and pertuzumab resulting from the unique antitumor activities of each agent.
