AI Article Synopsis

  • Failure of proper DNA damage sensing and repair can lead to serious diseases, including neurodegenerative disorders, cancer, and infertility.
  • The DNA damage response (DDR) relies on a network of proteins activated through post-translational modifications (PTMs), particularly by molecules like ubiquitin and SUMO.
  • The article reviews current research on the DDR, emphasizing the roles of ubiquitylation and neddylation in repairing DNA double-strand breaks (DSBs).

Article Abstract

Failure of accurate DNA damage sensing and repair mechanisms manifests as a variety of human diseases, including neurodegenerative disorders, immunodeficiency, infertility and cancer. The accuracy and efficiency of DNA damage detection and repair, collectively termed the DNA damage response (DDR), requires the recruitment and subsequent post-translational modification (PTM) of a complex network of proteins. Ubiquitin and the ubiquitin-like protein (UBL) SUMO have established roles in regulating the cellular response to DNA double-strand breaks (DSBs). A role for other UBLs, such as NEDD8, is also now emerging. This article provides an overview of the DDR, discusses our current understanding of the process and function of PTM by ubiquitin and NEDD8, and reviews the literature surrounding the role of ubiquitylation and neddylation in DNA repair processes, focusing particularly on DNA DSB repair.

Chemotherapy resistance has long stood in the way of therapeutic advancement for lung cancer patients, the malignant tumor with the highest incidence and fatality rate in the world. Patients with lung adenocarcinoma (LUAD) now have a dismal prognosis due to the development of cisplatin (DDP) resistance, forcing them to use more costly second-line therapies. Therefore, overcoming resistance and enhancing patient outcomes can be achieved by comprehending the regulatory mechanisms of DDP resistance in LUAD.

Inadvertent exposure to aristolochic acids (AAs) is causing chronic renal disease worldwide, with aristolochic acid I (AA-I) identified as the primary toxic agent. This study employed chemical methods to investigate the mechanisms underlying the nephrotoxicity and carcinogenicity of AA-I. Aristolochic acid II (AA-II), which has a structure similar to that of AA-I, was investigated with the same methods for comparison.

Targeting CHEK1: Ginsenosides-Rh2 and Cu2O@G-Rh2 nanoparticles in thyroid cancer.

Cell Biol Toxicol

January 2025

Department of Radiology, Shengjing Hospital of China Medical University, No. 36 Sanhao Street, Heping District, Shenyang, 110004, Liaoning Province, China.

Thyroid cancer (THCA) is an increasingly common malignant tumor of the endocrine system, with its incidence rising steadily in recent years. For patients who experience recurrence or metastasis, treatment options are relatively limited, and the prognosis is poor. Therefore, exploring new therapeutic strategies has become particularly urgent.

Disproportion between reactive oxygen species (ROS) production and the body's antioxidant system can cause oxidative stress, which is considered a common denominator in various pathological conditions, including cardiovascular diseases, aging, and cognitive disorders. The generation of free radicals, which occurs through partial reduction of oxygen, can quickly overwhelm the endogenous antioxidant system capacity of the cell. This causes lipid, protein, DNA and RNA damage, inflammation, and overall cell degeneration, which can be mitigated by various antioxidants.
