Interaction of RECQL4 with poly(ADP‐ribose) is critical for the DNA double‐strand break response in human cells

open access: yesFEBS Open Bio
To overcome genotoxicity, cells have evolved powerful and effective mechanisms to detect and respond to DNA lesions. RecQ Like Helicase‐4 (RECQL4) plays a vital role in DNA damage responses. RECQL4 is recruited to DNA double‐strand break (DSB) sites in a

The PARP1/ARTD1-Mediated Poly-ADP-Ribosylation and DNA Damage Repair in B Cell Diversification

open access: yesAntibodies, 2014
ADP-ribosylation is an essential post-translational modification, mediated by a family of proteins named poly-ADP-ribose polymerases/Diphtheria toxin-like ADP-ribosyltransferases (PARPs/ARTDs), that functions to assist in cellular homeostasis through an ...

Hsp90 Inhibition on the Western Blot: N‐Terminal Versus C‐Terminal Inhibitors in Breast Cancer

open access: yesMedicinal Research Reviews, EarlyView.
ABSTRACT Heat shock protein 90 (Hsp90) is an established and clinically validated anticancer target. By regulating the folding and maturation of diverse client proteins, it is indirectly involved in carcinogenesis. Key breast cancer oncogenic drivers, including estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2, are ...

Harnessing benzamides as plant stress inhibitors, growth promoters and in management of crop resilience—A review

open access: yesPlant Biology, EarlyView.
Benzamides boost crop resilience by inhibiting poly(ADP‐ribose) polymerase (PARP) to enhance stress tolerance and, through their antimicrobial, herbicidal, and insecticidal derivatives, they offer broad protection for sustainable crop improvement. Abstract Benzamides have emerged as potent stress inhibitors and growth promoters in plant biotechnology ...

5mC-hydroxylase activity is influenced by the PARylation of TET1 enzyme [PDF]

open access: yes, 2015
5-hydroxymethylcytosine is a new epigenetic modification deriving from the oxidation of 5-methylcytosine by the TET hydroxylase enzymes. DNA hydroxymethylation drives DNA demethylation events and is involved in the control of gene expression ...

Structural and biochemical evidence supporting poly ADP-ribosylation in the bacterium Deinococcus radiodurans

open access: yesNature Communications, 2019
Poly-ADP-ribosylation (PARylation) is a well-known regulatory event in eukaryotes but has not yet been observed in bacteria. Here, the authors solve the structure of a bacterial PAR-glycohydrolase and provide evidence for a prokaryotic PARylation ...

Is there an epigenetic component underlying the resistance of triple-negative breast cancers to PARP inhibitors?

open access: yesFrontiers in Pharmacology, 2012
Poly(ADP-ribose)polymerase (Parp) is an enzyme responsible for catalyzing post-translational modifications through the addition of poly(ADP-ribose) chains (known as PARylation).

Oncogenic KRAS Rewires Stress Granule Dynamics: Mechanisms and Therapeutic Opportunities

open access: yesThe Kaohsiung Journal of Medical Sciences, Volume 42, Issue 9, September 2026.
ABSTRACT Stress granules (SGs) are dynamic, membrane‐less structures that form in response to various cellular stresses, including metabolic, oxidative, and therapeutic challenges. They function as adaptive hubs and reorganize protein synthesis and signaling networks to help cells survive under stress. In cancer, these condensates are often hijacked to

PARylation: Strengthening the Connection between Cancer and Pluripotency [PDF]

open access: yes, 2009
Pluripotency and tumorgenicity appear fundamentally linked. Recent investigations into the role of PARylation in chromatin remodeling (Ahel et al., 2009; Gottschalk et al., 2009), combined with the demonstration that p53 serves as a barrier to ...
