Molecular Basis for Uracil‐DNA‐Glycosylase to Identify DNA Damage in the Nucleosome

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The DNA base‐excision repair (BER) pathway is initiated by a glycosylase, such as uracil‐DNA‐glycosylase (UDG), which identifies and removes a wrong base incorporated in the DNA sequence. The very early steps in the identification of the DNA damage are crucial to the correct initiation of the repair chain, and become even more complex when ...

PARP1-dependent DNA-protein crosslink repair

DNA-protein crosslinks (DPCs) are toxic lesions that inhibit DNA related processes. Post-translational modifications (PTMs), including SUMOylation and ubiquitylation, play a central role in DPC resolution, but whether other PTMs are also involved remains

Immunomodulatory Properties of Withania somnifera: Regulation of Innate Immune Cells and Clinical Implications

Phytotherapy Research, EarlyView.
ABSTRACT Withania somnifera (L.) Dunal (WS), commonly known as Ashwagandha, is a prominent medicinal herb in Ayurveda, with extensive therapeutic potential attributed to its diverse phytochemical profile. This review critically examines the immunomodulatory properties of WS, focusing on innate immune cell populations, including neutrophils, eosinophils,

FANCJ promotes PARP1 activity during DNA replication that is essential in BRCA1 deficient cells

Nature Communications
The effectiveness of poly (ADP-ribose) polymerase inhibitors (PARPi) in creating single-stranded DNA gaps and inducing sensitivity requires the FANCJ DNA helicase. Yet, how FANCJ relates to PARP1 inhibition or trapping, which contribute to PARPi toxicity,

DePARylation prevents DNA replication-driven PARP1 condensation

PARG, the primary enzyme responsible for the reversal of PARP1-mediated poly(ADP-ribosyl)ation, has attracted considerable attention as a therapeutic target in cancer. Yet, the mechanisms underlying PARG inhibitor (PARGi) efficacy remain elusive. Herein,

Impact of sleep insufficiency and recovery on cancer development

Sleep Research, EarlyView.
Abstract Sleep plays a critical role in overall health, and modern lifestyles, such as shift work and late‐night activities, can significantly impact sleep condition. Insufficient sleep has been associated with various adverse health outcomes, including an increased risk of tumor development.

Mepolizumab Modifies Blood Eosinophil Proteome and Transcriptome in Severe Eosinophilic Asthma

Allergy, EarlyView.
This study investigates the effect of mepolizumab on the proteomic and transcriptomic profile of blood eosinophils in SEA patients. Mepolizumab reduces the migratory capacity and effector‐related molecular signatures of circulating eosinophils in SEA patients.

A Spotlight on Yolk‐sac Tumors: Molecular Pathology, Current Diagnostics, and Novel Therapeutics

Andrology, EarlyView.
ABSTRACT Background Yolk‐sac tumors are an aggressive subtype of testicular cancer that significantly contribute to disease progression and therapy resistance, especially in adults. While testicular cancer generally has high cure rates with cisplatin‐based treatment, adult yolk‐sac tumors often appear as components of mixed tumors with poor response to

sGC stimulator BAY 41‐8543 improves survival and ventricular function in a rat model of doxorubicin‐induced cardiomyopathy with nephrotic syndrome

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Anthracyclines such as doxorubicin (DOXO) remain a cornerstone of cancer therapy but are associated with a high risk of cardiotoxicity and subsequent heart failure (HF). Impairment of NO/soluble guanylyl cyclase (sGC)/cGMP pathway has been reported in anthracycline‐induced cardiomyopathy.
