Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

CDK1 Enhances Mitochondrial Bioenergetics for Radiation-Induced DNA Repair

open access: yesCell Reports, 2015
Nuclear DNA repair capacity is a critical determinant of cell fate under genotoxic stress conditions. DNA repair is a well-defined energy-consuming process.

Nuclear plasticity increases susceptibility to damage during confined migration.

open access: yesPLoS Computational Biology, 2020
Large nuclear deformations during migration through confined spaces have been associated with nuclear membrane rupture and DNA damage. However, the stresses associated with nuclear damage remain unclear.

Expression of the DNA mismatch repair proteins hMLH1 and hPMS2 in normal human tissues. [PDF]

open access: yes, 1997
hMLH1 and hPMS2 are part of the DNA mismatch repair complex. Mutations in these genes have been linked to hereditary non-polyposis colon cancer; they also occur in a variety of sporadic cancers. Western blot analysis and immunohistochemistry demonstrated

The role of histone modifications in transcription regulation upon DNA damage

open access: yesFEBS Letters, EarlyView.
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

Viral protease binds to nucleosomal DNA and cleaves nuclear cGAS that attenuates type I interferon

open access: yesmBio
Nuclear cyclic GMP-AMP synthetase (cGAS) binds to nucleosome with high affinity to prevent its activation by self-DNA. Upon stimulation with double-stranded DNA, cGAS is activated and translocates from the nucleus to the cytoplasm, guided by its N ...

DNA methylation status of nuclear-encoded mitochondrial genes underlies the tissue-dependent mitochondrial functions

open access: yesBMC Genomics, 2010
Background Mitochondria are semi-autonomous, semi-self-replicating organelles harboring their own DNA (mitochondrial DNA, mtDNA), and their dysregulation is involved in the development of various diseases.

Dicer prevents genome instability in response to replication stress [PDF]

open access: yes, 2019
Dicer, an endoribonuclease best-known for its role in microRNA biogenesis and RNA interference pathway, has been shown to play a role in the DNA damage response and repair of double-stranded DNA breaks (DSBs) in mammalian cells.

Integration of circadian and hypoxia signaling via non‐canonical heterodimerization

open access: yesFEBS Letters, EarlyView.
CLOCK, BMAL1, and HIFs are basic helix‐loop‐helix and Per‐Arnt‐Sim domain (bHLH‐PAS) proteins, which function as transcription factors. bHLH‐PAS proteins are designated in two classes. Many class I proteins are regulated by environmental signals via their PAS domains, but such signals have not been identified for all.
