Abstract 1907: Claudin 6 is a carcinoembryonic antigen with cancer stem cell marker features
2018
Abstract Background Claudin 6 (CLDN6) is a tight junction membrane protein whose expression in normal tissue is confined to embryonic cells, but is aberrantly expressed in various human cancers, such as ovarian cancer (OC) and testicular cancer (TC). A monoclonal antibody against CLDN6, IMAB027, has shown promising antitumor activity in preclinical human CLDN6-positive (CLDN6+) cancer models. In this series of nonclinical studies, we investigated CLDN6 expression in normal and cancer tissues, as well as the localization and possible function of CLDN6 in cancer cells. Methods Expression of CLDN6 was assessed in a wide range of human tissues (eg, lung, colon, skin, ovary) and cultured cells b…
Chromatin Immunoprecipitation Assay to Identify Genomic Binding Sites of Regulatory Factors
2016
DNA-protein interactions are vital to fundamental cellular events including transcription, replication, DNA repair, and recombination. Thus, their study holds the key to our understanding of mechanisms underlying normal development and homeostasis as well as disease. Transcriptional regulation is a highly complex process that involves recruitment of numerous factors resulting in formation of multi-protein complexes at gene promoters to regulate gene expression. The studied proteins can be, for example, transcription factors, epigenetic regulators, co-activators, co-repressors, or ligand-activated nuclear receptors as estrogen receptor-α (ERα) bound either directly to the DNA or indirectly b…
Confidence-based Somatic Mutation Evaluation and Prioritization
2012
Next generation sequencing (NGS) has enabled high throughput discovery of somatic mutations. Detection depends on experimental design, lab platforms, parameters and analysis algorithms. However, NGS-based somatic mutation detection is prone to erroneous calls, with reported validation rates near 54% and congruence between algorithms less than 50%. Here, we developed an algorithm to assign a single statistic, a false discovery rate (FDR), to each somatic mutation identified by NGS. This FDR confidence value accurately discriminates true mutations from erroneous calls. Using sequencing data generated from triplicate exome profiling of C57BL/6 mice and B16-F10 melanoma cells, we used the exist…
