Improved limit on the directly measured antiproton lifetime

2017

Continuous monitoring of a cloud of antiprotons stored in a Penning trap for 405 days enables us to set an improved limit on the directly measured antiproton lifetime. From our measurements we extract a storage time of $3.15\times {10}^{8}$ equivalent antiproton-seconds, resulting in a lower lifetime limit of ${\tau }_{\bar{{\rm{p}}}}\gt 10.2\,{\rm{a}}$ with a confidence level of $68 \% $. This result improves the limit on charge-parity-time violation in antiproton decays based on direct observation by a factor of 7.

Determination of essential biomarkers in lung cancer: a real-world data study in Spain with demographic, clinical, epidemiological and pathological c…

2022

Abstract Background The survival of patients with lung cancer has substantially increased in the last decade by about 15%. This increase is, basically, due to targeted therapies available for advanced stages and the emergence of immunotherapy itself. This work aims to study the situation of biomarker testing in Spain. Patients and methods The Thoracic Tumours Registry (TTR) is an observational, prospective, registry-based study that included patients diagnosed with lung cancer and other thoracic tumours, from September 2016 to 2020. This TTR study was sponsored by the Spanish Lung Cancer Group (GECP) Foundation, an independent, scientific, multidisciplinary oncology society that coordinates…

Abstract B09: Nintedanib inhibits tumor and vessel growth and leads to vascular normalization in A549-NSCLC-xenografts

2015

Abstract Angiogenesis plays a major role in the growth and progression of non-small-cell lung cancer (NSCLC). The triple angiokinase inhibitor nintedanib is a potent inhibitor of the receptor tyrosine kinases FGFR-1, 2, 3, PDGFR-α and β, VEGFR-1, 2, 3. and Flt-3. as well as of non-receptor tyrosine kinases like Src, Lyn and Lck by occupying the intracellular ATP-binding pocket. In the pivotal LUME-Lung 1 trial Nintedanib plus docetaxel has proven an overall survival benefit over docetaxel monotherapy in second-line treatment of non-small-cell lung cancer of adenocarcinoma. The aim of this study was to analyse treatment induced vascular normalization of nintedanib, bevacizumab and docetaxel …

A phase I, open-label, dose-escalation trial of BI 764532, a DLL3/CD3 bispecific antibody, in patients (pts) with small cell lung carcinoma (SCLC) or…

2021

TPS8588 Background: First-line standard of care for pts with metastatic SCLC and neuroendocrine carcinoma (NEC) is platinum-based chemotherapy ± immunotherapy. While the addition of anti-PD1 antibodies has improved outcomes, nearly all pts relapse and prognosis is poor. There is a major unmet need for additional treatment (tx) options. BI 764532 is a delta-like ligand 3 (DLL3)/CD3 T cell engaging bispecific antibody. DLL3 is expressed on the cell surface of many SCLC and NEC tumors, but not on normal cells. In preclinical studies, BI 764532 induced cytotoxicity of DLL3-positive cells and showed anti-tumor activity in animal models. Methods: NCT04429087 is a first-in-human, open-label, dose…

Abstract LB-243: Cetuximab and Artesunate synergistically inhibit the invasion and distant metastasis of non-small cell lung cancer

2012

Abstract Cancer is a complex disease and multi step process evolving from malfunctions of molecules and their complex networks which regulate this process. The blockage of the cancer signalling network is crucial in the cancer treatment. In some cases, single drug therapy might not be comprehensive enough to inhibit the activity of secondary signals, feedback regulations and resistance to particular molecules, due to their abundant expression or activity. An understanding of these complex phenomena in cancer therapy for the benefit of patients is essential, especially since it bears the chance to establish novel concepts of combination drug therapy. In the present study, we have tried to fi…

PO-224 Fourier transform infrared spectroscopy-based detection of hypoxia-induced biomolecular changes in different cancer cell lines

2018

Introduction Our previous studies have shown that under hypoxic stress human colorectal and breast cancer cells produce higher amounts of lipids compared to that under normoxic environment. The aim of this study was to estimate hypoxia induced cell metabolic response via the biochemical composition in prostate and lung cancer cells by using Fourier transform infrared spectroscopy (FTIR). Material and methods Lung cancer cell lines NCI-H69, COR-L23 and prostate cancer cell line PC3, and primary prostate cancer culture NFI-56 were seed in serum-free medium in density 1 × 106 per well in triplicates in 6-well plates and incubated for 48 in normoxic and hypoxic (5% CO2, 1% O2 and 94% N2) condit…

Highly specific auto-antibodies against claudin-18 isoform 2 induced by a chimeric HBcAg virus-like particle vaccine kill tumor cells and inhibit the…

2011

Abstract Strategies for antibody-mediated cancer immunotherapy, such as active immunization with virus-like particle (VLP)-based vaccines, are gaining increasing attention. We developed chimeric hepatitis B virus core antigen (HBcAg)-VLPs that display a surface epitope of the highly selective tumor-associated cell lineage marker claudin-18 isoform 2 (CLDN18.2) flanked by a mobility-increasing linker. Auto-antibodies elicited by immunization with these chimeric HBcAg-VLPs in 2 relevant species (mouse and rabbit) bind with high precision to native CLDN18.2 at physiologic densities on the surface of living cells but not to the corresponding epitope of the CLDN18.1 splice variant that differs b…

Presence of the Transmembrane Protein Neuropilin in Cytokine-induced Killer Cells

2020

Background/aim Cytokine-induced killer (CIK) cells are a heterogenous population of immune cells showing promising applications in immunotherapeutic cancer treatment. Neuropilin (NRP) proteins have been proven to play an important role in cancer development and prognosis. In this study, CIK cells were tested for expression of NRPs, transmembrane proteins playing a role in the proliferation and survival of cancer cells. Materials and methods CIK cells were analyzed at different time points via flow cytometry and quantitative real-time polymerase chain reaction for neuropilin expression. Results Phenotyping results showed CIK cells having developed properly, and low levels of NRP2 were detect…
