Abstract 3766: Targeting promoter regions of c-Myc and Bcl-2 in AML cells using G-quadruplex interacting drugs (original) (raw)

Cancer Research, 2016

Abstract

Cancer is a disease that can be characterized by overexpression of key oncogenic drivers that support tumor development and maintenance. In many instances, these oncogenic drivers are ‘undruggable’ because of structural challenges, the inability to effectively inhibit high concentrations of overexpressed proteins, and the development of drug resistance mutations. An alternative therapeutic approach is to directly inhibit gene transcription by targeting unique secondary DNA structures, called G-quadruplexes, that are associated with subsets of promoters. We investigated the activity of a class of compounds termed G-quadruplex Interacting Drugs (GQIDs) that are able to shut down the expression of specific oncogenic drivers, such as c-Myc and Bcl-2, used by tumor cells for growth and survival. We tested the activity of two GQIDs, GQC-05 and GSA-1103, on cell growth of a panel of eight pediatric and eight adult acute myeloid leukemia (AML) cell lines. Drug dose response analysis showed ...
