Crosstalk between signaling pathways and DNA damage response

Abstract

Living organisms have developed a complex signaling system to sense diverse growth signals and coordinate intracellular bioprocesses, so that they survive in various conditions. Since organisms are often exposed to environmental and genomic threats which cause DNA damages, DNA damage response (DDR) and repair systems are important for maintenance of genome stability and integrity. A line of evidences has demonstrated that there is tight crosstalk between growth signaling pathways and DDR systems. In this review, we give a brief overview of recent reports dissecting the interaction between signaling pathways and DDR at molecular level, which may further expand the knowledge of the signaling network and provide clues for disease therapy.
