AsSIRTing the DNA damage response [PDF]
In mammalian cells, changes in signaling networks and expressed proteins ensure the adequate detection and management of damaged macromolecules. Here, we review an emergent pathway of maintenance of homeostasis following genotoxic stress. The RNA-binding protein HuR associates with sirtuin (SIRT)1 mRNA and maintains constitutively elevated levels of ...

Phosphorylation events surrounding the DNA damage response in "Saccharomyces cerevisiae" [PDF]
Protein phosphorylation mediated by checkpoint kinases is crucial for the cellular response to DNA damage. The sensor kinases Mec1 and Tel1 initiate the checkpoint signaling cascade by directly activating the checkpoint effector kinase Rad53.

DNA replication is required for the checkpoint response to damaged DNA in Xenopus egg extracts. [PDF]
Alkylating agents, such as methyl methanesulfonate (MMS), damage DNA and activate the DNA damage checkpoint. Although many of the checkpoint proteins that transduce damage signals have been identified and characterized, the mechanism that senses the ...

The R2TP cochaperone complex plays a critical role in the assembly of multisubunit machines, including small nucleolar ribonucleoproteins (snoRNPs), RNA polymerase II, and the mTORC1 and SMG1 kinase complexes, but the molecular basis of substrate ...

DNA Damage and DNA Damage Response in Chronic Myeloid Leukemia [PDF]
DNA damage and alterations in the DNA damage response (DDR) are critical sources of genetic instability that might be involved in BCR-ABL1 kinase-mediated blastic transformation of chronic myeloid leukemia (CML). Here, increased DNA damage is detected by γH2AX foci analysis in peripheral blood mononuclear cells (PBMCs) of de novo untreated chronic ...

Bacterial Genotoxin-Induced DNA Damage and Modulation of the Host Immune Microenvironment
Bacterial genotoxins (BTGX) induce DNA damage, which results in senescence or apoptosis of the target cells if not properly repaired. Three BTGXs have been identified: the cytolethal distending toxin (CDT) family produced by several Gram-negative ...

The concerted roles of FANCM and Rad52 in the protection of common fragile sites
Fanconi anemia core proteins have been linked to common fragile site stability. Here the authors shed light into the role of FANCM in common fragile site protection by suppressing double-strand break formation and mitotic recombination.
