Tumor Cell Survival Dependence on the DExH-Box Helicase DHX9


ABSTRACT: The ATP-dependent DExH/D-box helicase DHX9 is a key participant in a number of gene regulatory steps, including transcriptional, translational, microRNA-mediated control, DNA replication, and maintenance of genomic stability. DHX9 has also been implicated in maintenance of the tumorigenic process and in drug response. Here, we report that inhibition of DHX9 expression is lethal to multiple human and mouse cancer cell lines. In contrast, using a novel conditional shDHX9 mouse model, we demonstrate that sustained and prolonged suppression of DHX9 is well tolerated at the organismal level. Our results demonstrate a robust tolerance for DHX9 knockdown in non-transformed cells and supports the targeting of DHX9 as an effective and specific chemotherapeutic approach. Comparison of gene expression in large intestine of mice with or without reduced expression of DHX9.

The NTP-dependent DExH/D-box helicase DHX9 is a key participant in a number of gene regulatory steps, including transcriptional, translational, and microRNA-mediated control, DNA replication and maintenance of genomic stability. DHX9 has also been implicated in tumor cell maintenance and drug response. Here we report that inhibition of DHX9 expression is lethal to human cancer cell lines and murine Eμ-Myc lymphomas. Using a novel conditional shDHX9 mouse model, we demonstrate that sustained and  ...[more]
