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 ...

Pyridazine Based Compounds with PARP-1 Inhibitory Activity

open access: yesArchives of Pharmaceutical Sciences Ain Shams University, 2023
Pyridazine-containing compounds have been identified as potent PARP1 inhibitors. The PARP is a family of enzymes essential for many cellular processes such as DNA repair, genomic stability, and apoptosis, also known as poly(ADP-ribose) synthetases and ...

The Nucleolus and PARP1 in Cancer Biology [PDF]

open access: yesCancers, 2020
The nucleolus has been known for a long time to fulfill crucial functions in ribosome biogenesis, of which cancer cells can become addicted to in order to produce sufficient amounts of proteins for cell proliferation. Recently, the nucleolus has emerged as a central regulatory hub in many other cancer-relevant processes, including stress sensing, DNA ...

Uncoupling of PARP1 trapping and inhibition using selective PARP1 degradation [PDF]

open access: yesNature Chemical Biology, 2019
PARP1 inhibitors (PARPi) are known to kill tumor cells via two mechanisms (PARP1 catalytic inhibition and PARP1 trapping). The relative contribution of these two pathways in mediating the cytotoxicity of PARPi, however, is not well understood. Here we designed a series of small molecule PARP degraders.

Dynamics of endogenous PARP1 and PARP2 during DNA damage revealed by live-cell single-molecule imaging

open access: yesiScience, 2023
Summary: PARP1 contributes to genome architecture and DNA damage repair through its dynamic association with chromatin. PARP1 and PARP2 (PARP1/2) recognize damaged DNA and recruit the DNA repair machinery.

PARP1 might enhance the therapeutic effect of tetrahydroxystilbene glucoside in traumatic brain injury via inhibition of Ras/JNK signalling pathway

open access: yesFolia Neuropathologica, 2020
Trauma is the main cause of death for people aged 1-45, and among them, traumatic brain injury (TBI) is the major condition, which causes over 50,000 deaths each year and costs over 80 billion per year.

Proteogenomic characterization of cholangiocarcinoma

open access: yesHepatology, EarlyView., 2022
Proteogenomic characterization of cholangiocarcinoma with therapeutic strategies Abstract Background and Aims Cholangiocarcinoma (CCA) is a highly heterogeneous cancer with limited understanding and few effective therapeutic approaches. We aimed at providing a proteogenomic CCA characterization to inform biological processes and treatment ...

Poly(ADP-Ribose) Polymerase-1 Lacking Enzymatic Activity Is Not Compatible with Mouse Development

open access: yesCells, 2023
Poly(ADP-ribose) polymerase-1 (PARP1) binds DNA lesions to catalyse poly(ADP-ribosyl)ation (PARylation) using NAD+ as a substrate. PARP1 plays multiple roles in cellular activities, including DNA repair, transcription, cell death, and chromatin ...

PAR recognition by PARP1 regulates DNA‐dependent activities and independently stimulates catalytic activity of PARP1 [PDF]

open access: yesThe FEBS Journal, 2021
Poly(ADP‐ribosyl)ation is predominantly catalyzed by Poly(ADP‐ribose) polymerase 1 (PARP1) in response to DNA damage, mediating the DNA repair process to maintain genomic integrity. Single‐strand (SSB) and double‐strand (DSB) DNA breaks are bona fide stimulators of PARP1 activity. However, PAR‐mediated PARP1 regulation remains unexplored.
