We analyzed alterations of PAR metabolism‐related proteins in PARG inhibitor‐resistant HCT116RPDD cells. Although PARG levels remained unchanged, HCT116RPDD cells exhibited reduced PARP1 and ARH3 expression and elevated PAR levels. Interestingly, HCT116RPDD cells exhibited slightly elevated intracellular NAD+/NADH and ATP levels. Our findings suggest a

Pan‐Modification Proteoformics: A Framework for Decoding Proteomic Complexity in Health and Disease
Post‐translational modification (PTM) diversity represents a central regulatory layer that drives protein functional complexity. Classical PTMs (phosphorylation, acetylation, ubiquitination, and glycosylation) and emerging PTMs (SUMOylation, lipidation, and ADP‐ribosylation) form dynamic modification codes that govern signaling, metabolism, and ...

The Role of One‐Carbon Metabolism in Cancer and Its Therapeutic Significance
One‐Carbon metabolism in T‐cell activation and tumor competition. T‐cell activation shifts metabolic pathways, promoting anabolic metabolism and bioenergetic capacity. One‐carbon metabolism plays a crucial role in histone and DNA methylation in activated T cells.

Poly(ADP-ribosyl)ation reactions in the regulation of nuclear functions [PDF]
Poly(ADP-ribosyl)ation is a post-translational modification of proteins. During this process, molecules of ADP-ribose are added successively on to acceptor proteins to form branched polymers. This modification is transient but very extensive in vivo, as polymer chains can reach more than 200 units on protein acceptors.

The role of histone modifications in transcription regulation upon DNA damage
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.

ADP-ribose hydrolases: biological functions and potential therapeutic targets
ADP-ribosylation (ADPRylation), which encompasses poly(ADP-ribosyl)ation and mono(ADP-ribosyl)ation, is an important post-translational modification catalysed by the poly(ADP-ribose) polymerase (PARP) enzyme superfamily.

Application of synthetic lethality screening in drug resistance models. Abstract Background and Rationale Synthetic lethality (SL)‐based strategies hold significant promise for overcoming therapeutic resistance, a critical bottleneck in cancer treatment where cancer cells evade anticancer therapies, leading to diminished efficacy or treatment failure ...

Biological Roles of Mono- and Poly (ADP-Ribosyl) ation
Biological roles of mono- and poly (ADP-ribosyl) ation reactions are reviewed, along with analysis of functional sequences of poly(ADP-ribose) synthetase and inhibitors of the synthetase compared with mono (ADP-ribosyl) transferase.

CCNE1 Exerts a Protective Effect on Parkinson's Disease by Regulating Ferroptosis‐Related Proteins
This study provides the first molecular insight into how CCNE1 exerts neuroprotective effects through the regulation of the ferroptosis key protein PARP16, offering a novel perspective for Parkinson's disease mechanism research. ABSTRACT Background The pathogenesis of Parkinson's disease (PD) is closely linked to ferroptosis, yet the mechanism by which
