Oxidative Stress in the Tumor Immune Microenvironment: Mechanisms and Therapeutic Perspectives

MedComm – Oncology, Volume 5, Issue 2, June 2026.
Oxidative stress is involved in several key processes in cancer, including redox regulation, DNA damage, post‐translational modifications, transcriptional regulation, epigenetic modifications, metabolic reprogramming, cell death, and immune modulation. These mechanisms collectively influence tumor progression, immune evasion, and therapeutic responses,

Molecular mechanism of poly(ADP-ribosyl)ation by PARP1 and identification of lysine residues as ADP-ribose acceptor sites [PDF]

, 2017
Poly(ADP-ribose) polymerase 1 (PARP1) synthesizes poly(ADP-ribose) (PAR) using nicotinamide adenine dinucleotide (NAD) as a substrate. Despite intensive research on the cellular functions of PARP1, the molecular mechanism of PAR formation has not been ...

Targeting EZH2 in Cancer: From Molecular Mechanisms to Clinical Translation

MedComm – Oncology, Volume 5, Issue 2, June 2026.
The abnormal overexpression or gain‐of‐function mutations of EZH2 play a significant role in cancer occurrence and progression, highlighting the importance and potential of EZH2 as a cancer biomarker. Therefore, screening for effective and safe small‐molecule inhibitors, degraders, and natural compounds targeting EZH2 through preclinical cancer models ...

Snapshots of Motion: A Novel Structural Intermediate Reveals Conserved Dynamics in Archaeal DNA Ligases

Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 6, Page 1245-1258, June 2026.
ABSTRACT We present the first x‐ray crystallographic structural evidence of an archaeal DNA ligase showing the AMP covalent adduct together with further cofactor hydrolysis, capturing a transient intermediary in the first step of the ligation reaction, triggered by the pyrophosphate hydrolysis.

Synergistic RU486 and olaparib therapy enhances apoptosis in endometriosis by simultaneously targeting hormonal signalling and DNA repair

British Journal of Pharmacology, Volume 183, Issue 11, Page 2947-2968, June 2026.
Background and Purpose Endometriosis is a chronic, hormone‐dependent disorder characterized by ectopic implantation of endometrial tissue, often accompanied by pain and infertility. Although the progesterone receptor modulator RU486 is effective for pain relief, its impact on lesion regression is limited, possibly due to apoptosis resistance and ...

Enhancing antitumour response to proteasome inhibitors with inhibitors of insulin‐degrading enzyme, a new molecular vulnerability in multiple myeloma

British Journal of Pharmacology, Volume 183, Issue 12, Page 3355-3376, June 2026.
Inhibitors of insulin‐degrading enzyme boost PI cytotoxicity through an increased sensitivity of proteasome to PI inhibitors, induction of ISR, DNA damage and Myc down‐regulation. They overcome PI resistance in vitro and induce tumour regression in vivo.

Intravesical Delivery of P21 mRNA–Loaded Lipid Nanoparticles as a Tumor Suppressor Replacement Therapy for Bladder Cancer

The FASEB Journal, Volume 40, Issue 10, 31 May 2026.
Intravesical delivery of p21 mRNA‐loaded lipid nanoparticles (p21‐LNP) restores the tumor suppressor p21 in bladder cancer. Localized p21 expression directly induces cell cycle arrest, DNA damage and apoptosis, and ultimately inhibits orthotopic tumor growth with minimal systemic distribution and favorable safety.

Respiratory Virus-Induced PARP1 Alters DC Metabolism and Antiviral Immunity Inducing Pulmonary Immunopathology

Viruses
Previous studies from our laboratory and others have established the dendritic cell (DC) as a key target of RSV that drives infection-induced pathology. Analysis of RSV-induced transcriptomic changes in RSV-infected DC revealed metabolic gene signatures ...

Update on PARP1 inhibitors in ovarian cancer

Annals of Oncology, 2011
The clinical development of PARP inhibitors for the treatment of tumors deficient in BRCA1 or BRCA2 is based on the concept of synthetic lethality. From the initial proof of concept study with the PARP1 inhibitor olaparib (AZD2281) in BRCA mutation carriers, in which 28% of ovarian cancer patients achieved an objective response, the target population ...

Facile Synthesis of H‐L‐Photo‐Lysine and Its Genetic Incorporation Into Proteins

ChemBioChem, Volume 27, Issue 10, 27 May 2026.
An efficient synthesis of a diazirine‐based noncanonical amino acid (ncAA), photo‐lysine (photoK), is reported, and its genetic incorporation into green fluorescent protein (GFP) is demonstrated. PhotoK‐enabled crosslinking is used to capture substrates and interaction partners of SIRT6 in vitro, in Escherichia coli, and in HEK293 cell lysates ...
