Engineering Extracellular Vesicles for Anti‐Aging Therapy: Mechanisms, Applications, and Perspectives

Aging Cell, Volume 25, Issue 7, July 2026.
This review systematically elucidates the multifactorial anti‐aging mechanisms of extracellular vesicles (EVs). By bridging fundamental biology with advanced bioengineering, scalable manufacturing, and clinical translation, it establishes a comprehensive framework for developing next‐generation EVs‐based precision nanotherapeutics to combat systemic ...

AKR1C3 Binds β‐Trcp to Promote the Degradation of TFRC to Protect Hepatocellular Carcinoma From Ferroptosis

Cancer Science, Volume 117, Issue 7, Page 1867-1882, July 2026.
In this study, we show that aldo‐keto reductase family 1 member C3 (AKR1C3), a protein highly expressed in ferroptosis resistant hepatocellular carcinoma cells, acts as an enzyme‐independent scaffold protein by promoting the nuclear export of β‐transducin repeat protein (β‐TrCP) and its binding to transferrin receptor (TFRC) in an enzyme‐independent ...

Pegargiminase Suppresses the Fanconi Anemia Pathway and Promotes Melphalan‐Induced DNA Double‐Strand Breaks in Uveal Melanoma

Pigment Cell &Melanoma Research, Volume 39, Issue 4, July 2026.
ADI‐PEG20 enhances melphalan‐induced DNA DSBs in UM cells. We describe potentiation of DNA DSBs in UM cell lines upon treatment with ADI‐PEG20 and melphalan (92.1 cells with STRIDE by intoDNA). ADI‐PEG20 suppresses multiple members of the FA pathway—a known resistance mechanism for melphalan—providing a rationale for exploring this drug combination in ...

Synergistic Cellular Toxicity from Inhibition of Poly(ADP-ribose) Glycohydrolase (PARG) and Ubiquitin-Specific Protease 1 (USP1)

Toxics
Ubiquitin-specific protease 1 (USP1) is an emerging target for poly(ADP-ribose) polymerase 1 (PARP1) inhibitor-resistant and BRCA1/BRCA2 mutant tumors.

ID3 deficiency alters chromatin accessibility at DSB sites and enhances vulnerability to HDAC inhibition

International Journal of Cancer, Volume 158, Issue 12, Page 3173-3186, 15 June 2026.
What's new? Errors in DNA double‐strand break (DSB) repair can lead to mutations, chromosomal instability, and ultimately cancer. Inhibitor of DNA‐binding 3 (ID3), a transcriptional repressor, is crucial to promoting DSB repair and helping maintain genome stability. Here, the authors investigated ID3 regulation of DNA repair via chromatin accessibility

Abstract 1706: Impact of PARP1 on AR signaling and therapeutic response in prostate cancer

, 2010
Poly (ADP-ribose) polymerase 1 (PARP1) modifies various nuclear proteins by poly (ADP-ribose)-ylation, and has a known role in a multitude of chromatin-associated functions, including: transcriptional coregulation, modification of chromatin structure ...

Minimizing DNA trapping while maintaining activity inhibition via selective PARP1 degrader

Cell Death and Disease
Poly (ADP-ribose) polymerase 1 (PARP1) catalyzes poly (ADP) ribosylation reaction, one of the essential post-translational modifications of proteins in eukaryotic cells.

Compromising PARP1 enzymatic activity disrupts co-localization of nucleolar proteins.

, 2012
A–D. The dissected pairs of salivary glands expressing CC01311 nucleolar GFP were split into left and right individual glands and stained separately using antibody against nucleolar protein Fibrillarin (A, C) and nucleolar antibody AJ1 (B, D).

Design, synthesis and anti-breast cancer activity evaluation of 6,7-dihydro-5H-pyrrolo[3,4-d]pyrimidine-based PARP1/ATR dual inhibitors

Journal of Enzyme Inhibition and Medicinal Chemistry
PARP1 inhibitors are FDA-approved for BRCA1/2-mutated breast cancer but show limited efficacy in wild-type cancers and face resistance issues. To overcome these, we designed novel 6,7-dihydro-5H-pyrrolo[3,4-d]pyrimidine-based compounds integrating PARP1 ...
