AI Article Synopsis

  • ATM (Ataxia-telangiectasia mutated) is a protein associated with a genetic disorder called ataxia-telangiectasia, which leads to neurological issues, immune deficiencies, and increased cancer risk due to its role in DNA damage detection and response.
  • Inhibiting ATM can make tumor cells more sensitive to treatments like radiation and chemotherapy, which is valuable for addressing treatment resistance in cancer patients.
  • The document reviews the progress and challenges of developing ATM inhibitors over the past twenty years, highlighting their potential in cancer treatment and neurodegenerative diseases while offering insights for future research.

Article Abstract

Ataxia-telangiectasia mutated (ATM) was first discovered in patients with AT (ataxia telangiectasia), which is characteristic with cerebellar degeneration, immunodeficiency, being susceptible to malignant tumors and sensitive to radiation. ATM kinase could detect DNA double-strand breaks and play a vital role in the DNA damage response. Inhibiting the function of ATM could sensitize tumor cells to both ionizing radiation (IR) and chemotherapy, as well as improve the chemoresistance and radioresistance observed in some patients. As such, ATM is a novel and important target for the cancer therapy. We reviewed ATM inhibitors reported in the last two decades, focusing on their development process, structure-activity relationships, inhibitory efficacy, pharmacokinetics and pharmacodynamics characteristics in the preclinical and clinical studies. We summarized the clinical value of ATM inhibitors in tumors and some neurodegenerative diseases, as well as the main challenges to the development of the drugs, providing directions and references for the future development of ATM inhibitors.

Background: We present a systematic review and meta-analysis of randomized clinical trials (RCTs) with PARPi either as monotherapy or in combination with an androgen receptor-targeted agent (ARTA) in first- and second-line settings.

Methods: Primary endpoints are radiographic progression free survival (rPFS) and overall survival (OS) in patients with mCRPC and either unselected, homologous recombination repair wild-type (HRR-), homologous recombination repair mutated (HRR+) or with BRCA1, BRCA2, or ATM mutation. The effect of PARPi + ARTA in the second-line setting is also explored.

The protective effects of mangiferin (MAG) against etoposide- and high glucose (HG)-induced DNA damage and aging were investigated in human bone marrow-mesenchymal stem cells (hBM-MSCs). Etoposide, a topoisomerase II inhibitor, was used to induce double-strand breaks (DSBs) in hBM-MSCs, resulting in increased genotoxicity, elevated levels of the DNA damage sensor ATM and CDKN1A, and decreased levels of the aging markers H3 and H4. MAG activated AMPK and SIRT1, thus protecting against DSB-induced damage.

Quinoline is a highly privileged scaffold with significant pharmacological potential. Introducing a carbonyl group into the quinoline ring generates a quinolone ring, which exhibits promising biological properties. Incorporating a carboxamide linkage at different positions within the quinoline and quinolone frameworks has proven an effective strategy for enhancing pharmacological properties, particularly anticancer potency.

High-grade serous carcinomas (HGSCs) with homologous recombination deficiency (HRD) respond favorably to platinum therapy and poly ADP ribose polymerase (PARP) inhibitors. Mutations in BRCA1 and BRCA2 commonly cause HRD and have been associated with Solid, pseudoEndometrioid, and Transitional-like (SET-like) histology. Mutations in other homologous recombination repair (HRR) genes as well as epigenetic changes can also result in HRD; however, morphologic correlates have not been well-explored in these cases.

DNA damage response (DDR) is a highly conserved and complex signal transduction network required for preserving genome integrity. DNA repair pathways downstream of DDR include the tyrosyl-DNA phosphodiesterase1 (TDP1) enzyme that hydrolyses the phosphodiester bond between the tyrosine residue of topoisomerase I (TopI) and 3'-phosphate end of DNA. A small TDP1 subfamily, composed of TDP1α and TDP1β, is present in plants.
