Oncogenic KRAS Rewires Stress Granule Dynamics: Mechanisms and Therapeutic Opportunities

The Kaohsiung Journal of Medical Sciences, Volume 42, Issue 9, September 2026.
ABSTRACT Stress granules (SGs) are dynamic, membrane‐less structures that form in response to various cellular stresses, including metabolic, oxidative, and therapeutic challenges. They function as adaptive hubs and reorganize protein synthesis and signaling networks to help cells survive under stress. In cancer, these condensates are often hijacked to

Twisting the End Game: How Telomere Chromatin Modifications Shape Telomere Maintenance

Aging Cell, Volume 25, Issue 9, September 2026.
Chromatin modifications on telomeres are linked to the mode of telomere DNA replication. A coupled feedforward loop model is proposed based on these to lock the ALT cancer cells in this alternative mode of telomere replication. ABSTRACT Cell division inevitably shortens telomeric DNA owing to the end‐replication problem.

ROS‐ATM‐CBP axis‐mediated PARP1 lactylation aggravates doxorubicin‐induced cardiotoxicity

Clinical and Translational Medicine, Volume 16, Issue 8, August 2026.
ROS function as signalling molecules to promote CBP‐mediated PARP1 lactylation in an ATM dependent manner, which induces PARP1 PARylation and ultimate cell apoptosis. CBP and SIRT1 as specific lactyltransferase and delactylase of PARP1. Lactylation of PARP1 depends on the LDHA activity and lactate production.

Anticancer sensitivities and biological characteristics of HCT116 cells resistant to the selective poly(ADP‐ribose) glycohydrolase inhibitor

FEBS Open Bio, Volume 16, Issue 5, Page 1020-1029, May 2026.
We analyzed alterations of PAR metabolism‐related proteins in PARG inhibitor‐resistant HCT116RPDD cells. Although PARG levels remained unchanged, HCT116RPDD cells exhibited reduced PARP1 and ARH3 expression and elevated PAR levels. Interestingly, HCT116RPDD cells exhibited slightly elevated intracellular NAD+/NADH and ATP levels. Our findings suggest a

Nicaraven induces programmed cell death by distinct mechanisms according to the expression levels of Bcl-2 and poly (ADP-ribose) glycohydrolase in cancer cells

Translational Oncology, 2022
The PARP-1 expression level and poly (ADP-ribosyl)ation activity in cancer markedly affect the therapeutic outcome. Nicaraven, a free radical scavenger has been found to inhibit PARP, but the effect on cancer cells is still unclear.

Pan‐Modification Proteoformics: A Framework for Decoding Proteomic Complexity in Health and Disease

Barrier Immunity, Volume 2, Issue 1, Page 32-49, March 2026.
Post‐translational modification (PTM) diversity represents a central regulatory layer that drives protein functional complexity. Classical PTMs (phosphorylation, acetylation, ubiquitination, and glycosylation) and emerging PTMs (SUMOylation, lipidation, and ADP‐ribosylation) form dynamic modification codes that govern signaling, metabolism, and ...

Selective modulation by PARP-1 of HIF-1α-recruitment to chromatin during hypoxia is required for tumor adaptation to hypoxic conditions

Redox Biology, 2021
Background: The adaptation to hypoxia is mainly controlled by the HIF transcription factors. Increased expression/activity of HIF-1α correlates with poor prognosis in cancer patients.

The Role of One‐Carbon Metabolism in Cancer and Its Therapeutic Significance

MedComm – Oncology, Volume 5, Issue 1, March 2026.
One‐Carbon metabolism in T‐cell activation and tumor competition. T‐cell activation shifts metabolic pathways, promoting anabolic metabolism and bioenergetic capacity. One‐carbon metabolism plays a crucial role in histone and DNA methylation in activated T cells.

ADP-ribose hydrolases: biological functions and potential therapeutic targets

Expert Reviews in Molecular Medicine
ADP-ribosylation (ADPRylation), which encompasses poly(ADP-ribosyl)ation and mono(ADP-ribosyl)ation, is an important post-translational modification catalysed by the poly(ADP-ribose) polymerase (PARP) enzyme superfamily.

The role of histone modifications in transcription regulation upon DNA damage

FEBS Letters, Volume 600, Issue 4, Page 418-438, February 2026.
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.
