Loss of nuclear DNA ligase III reverts PARP inhibitor resistance in BRCA1/53BP1 double-deficient cells by exposing ssDNA gaps

open access: yes, 2021
Inhibitors of poly(ADP-ribose) (PAR) polymerase (PARPi) have entered the clinic for the treatment of homologous recombination (HR)-deficient cancers. Despite the success of this approach, preclinical and clinical research with PARPi has revealed multiple

Real‐World HRR Testing Pathways and Patterns of Detected Alterations in Prostate Cancer From the Multinational ARON‐3 Study

open access: yesThe Prostate, EarlyView.
ABSTRACT Background Homologous recombination repair (HRR) testing is increasingly relevant in prostate cancer because it identifies patients who may benefit from biomarker‐guided treatment strategies, including poly(ADP‐ribose) polymerase inhibitors (PARPi).

Resistance to PARP-inhibitors in Cancer Therapy

open access: yesFrontiers in Pharmacology, 2013
The pharmacological inhibitors of poly(ADP-ribose) polymerase (PARP) family of proteins have shown promising results in preclinical studies and clinical trials as a monotherapy or in combination therapy for some cancers.

A guide to transcriptional cyclin‐dependent kinases in cancer

open access: yesThe FEBS Journal, EarlyView.
Transcriptional cyclin‐dependent‐kinases (tCDKs) facilitate gene expression by promoting RNA polymerase II (RNAPII) progression through discrete phases of the transcription cycle. Aberrant tCDK activity is detectable in different human cancers, thereby contributing to de‐regulated gene expression programs that drive oncogenic phenotypes.

Selective autophagy pathways in ageing and neurodegeneration: Emerging roles for mitophagy and nucleophagy

open access: yesThe FEBS Journal, EarlyView.
As we age, cells gradually accumulate damage, which can contribute to disease and neurodegeneration. This review explores how two cellular recycling processes, mitophagy and nucleophagy, remove damaged mitochondria and nuclear material, respectively, to maintain cell health and long‐term neuronal homeostasis.

PARP1-BCAT2 axis upregulates ABCG1 via histone lactylation to drive acquired PARP inhibitor resistance in prostate cancer

open access: yesJournal of Experimental & Clinical Cancer Research
Background Poly (ADP-ribose) polymerase inhibitor (PARPi) resistance poses a significant challenge in prostate cancer (PCa). Although branched-chain amino acid (BCAA) metabolism is implicated in cancer biology, its specific role in PARPi resistance ...

Mechanism of PARP inhibitor resistance and potential overcoming strategies

open access: yesGenes and Diseases
PARP inhibitors (PARPi) are a kind of cancer therapy that targets poly (ADP-ribose) polymerase. PARPi is the first clinically approved drug to exert synthetic lethality by obstructing the DNA single-strand break repair process.

Cross‐Regulation Between DNA Methylation and Circadian Clock Reprogramming in Ovarian Cancer: Mechanistic Insights, Biomarker Potential, and Therapeutic Implications

open access: yesInternational Journal of Cancer, Volume 160, Issue 1, Page 7-23, 1 January 2027.
ABSTRACT Early diagnosis remains challenging, recurrence rates remain high, and platinum resistance frequently develops in ovarian cancer (OC), collectively representing major barriers to long‐term patient survival. DNA methylation (DNAm), as a relatively stable yet dynamically modifiable epigenetic signature, can capture alterations in tumor states ...

Prickle4 Drives Microenvironmental Remodeling and Resistance to Parp Inhibition in IDH‐Mutant Glioma

open access: yesAdvanced Science
Mutations in isocitrate dehydrogenase (IDH) genes sensitize gliomas to PARP inhibition (PARPi) by inducing epigenetic reprogramming of DNA damage repair circuits. However, tumors treated with PARPi eventually relapse despite initial responsiveness.

Ferroportin deficiency drives olaparib resistance in ovarian cancer via the cGAS–STING–STAT3 survival axis

open access: yesClinical and Translational Medicine, Volume 16, Issue 11, November 2026.
Abstract Background Ovarian cancer (OC) remains the most lethal gynaecological malignancy, and acquired resistance to PARP inhibitors such as olaparib represents a major clinical challenge. Although dysregulation of iron metabolism has been implicated in tumorigenesis, the specific role of the iron exporter SLC40A1 (ferroportin, FPN) in mediating ...
