PARP1 condensates differentially partition DNA repair proteins and enhance DNA ligation
Poly(ADP-ribose) polymerase 1 (PARP1) is one of the first responders to DNA damage and plays crucial roles in recruiting DNA repair proteins through its activity – poly(ADP-ribosyl)ation (PARylation). The enrichment of DNA repair proteins at sites of DNA

Poly(ADP-Ribosyl)ation Affects Histone Acetylation and Transcription.
Poly(ADP-ribosyl)ation (PARylation) is a posttranslational protein modification catalyzed by members of the poly(ADP-ribose) polymerase (PARP) enzyme family.

TRIM25 acts as a multifunctional hub driving intervertebral disc degeneration under mechanical stress. Mechanical compression significantly upregulates TRIM25 expression, establishing it as a key E3 ubiquitin ligase platform. TRIM25 targets PARG and Ku80 via distinct molecular interfaces, triggering their ubiquitination and degradation.

Visualization of a DNA-PK/PARP1 complex [PDF]
The DNA-dependent protein kinase (DNA-PK) and Poly(ADP-ribose) polymerase-1 (PARP1) are critical enzymes that reduce genomic damage caused by DNA lesions.

NAD+‒circadian rhythm coupling in dementia
Abstract The circadian rhythm system and sleep coordinate whole‐body functions across the 24‐h cycle, yet these rhythms progressively deteriorate with neurodegenerative diseases, including dementia. Growing evidence indicates that nicotinamide adenine dinucleotide (NAD+) interacts with the circadian system through multiple molecular pathways and that ...

Inhibition of DNA damage repair is a common mechanism to induce cancer cell death and, therefore, to treat cancers such as breast, prostate and ovarian cancer. This approach, although very attractive, has not been feasible for treating brain tumours due to the stringent structural features necessary for pharmaceutical agents to cross the blood–brain ...

Cell Identification and Aging Index (CIAdex) harnesses single‐cell infrared spectral fingerprints to provide label‐free cell identification and quantitative aging assessment. By integrating machine learning with Fourier‐transform infrared (FTIR) microspectroscopy, this framework distinguishes cell types, donors, and batches while tracking aging ...

Deficiency of Parkinson's disease-related gene Fbxo7 is associated with impaired mitochondrial metabolism by PARP activation [PDF]
The Parkinson's disease (PD)-related protein F-box only protein 7 (Fbxo7) is the substrate-recognition component of the Skp1-Cullin-F-box protein E3 ubiquitin ligase complex.
