Extracellular vesicles in pharmacology: Innovations in drug delivery and therapeutic applications in cancer

British Journal of Pharmacology, EarlyView.
Extracellular vesicles (EVs) are a diverse population of membrane nanoparticles secreted by nearly all cell types, playing a key role in intercellular communication by transferring bioactive macromolecular cargo. In cancer, EVs shape both the local tumour microenvironment and distant premetastatic niches.

Histone deacetylase inhibitors as venetoclax‐sensitising partners in acute myeloid leukaemia: Mechanisms, pharmacology and translational perspectives

British Journal of Pharmacology, EarlyView.
Abstract Venetoclax combined with hypomethylating agents has improved treatment for older or unfit patients with acute myeloid leukaemia (AML), but resistance and relapse remain common. This review analyses the rationale for combining venetoclax with inhibitors of histone deacetylase (HDAC).

Cytology‐First Diagnostic Workflow for Melanoma of Unknown Primary With Molecular Profiling

Cytopathology, EarlyView.
Cytology‑first diagnostic workflow for melanoma of unknown primary. Fine‑needle aspiration of an enlarged lymph node enables rapid cytologic evaluation and immunocytochemical confirmation of melanocytic lineage (SOX10). This early cytologic diagnosis facilitates timely surgical excision and comprehensive genomic profiling, supporting integrated ...

Multimodal Exploratory Analysis of Persistent Diabetic Macular Edema: Integrating Aqueous Humour Metabolomics, Clinical and OCT Features

Diabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Purpose This exploratory study integrates aqueous humour metabolomic data with clinical and imaging features to examine candidate biomarkers and characterize multimodal patterns associated with persistent diabetic macular edema (pDME). Methods In this prospective cohort study, DME patients were treated with monthly anti‐VEGF injections over 3 ...

Compromised DNA replication in gut cells underlies sensitivity to genotoxic stress in the tardigrade Hypsibius exemplaris

The FEBS Journal, EarlyView.
DNA damage in the tardigrade Hypsibius exemplaris elicits distinct cellular outcomes depending on replication status. While non‐replicating cells tolerate genotoxic stress, constitutively replicating cells undergo irreversible replication failure upon DNA damage, leading to loss of tissue homeostasis, fat depletion, sterility, and organismal death ...

L'inhibition de PARP1 autonome des cellules cancéreuses améliore l'immunosurveillance

, 2021
Poly (ADP-ribose) polymerase 1 (PARP1) is an enzyme whose high activity in non-small cell lung cancer (NSCLC) in humans has a poor prognosis and correlates with low tumor infiltration of cytotoxic lymphocytes.

Tankyrase‐2 regulates adipocyte differentiation through AMPK/mTOR signaling

The FEBS Journal, EarlyView.
Tankyrase 2 (TNKS2), a PARP family member, underpins adipocyte differentiation. TNKS2 controls LKB1 protein level, and consequently, the activity of the mTOR/AMPK system and adipocyte differentiation through a layered process. Pharmacological inhibition of TNKS2 leaves other PARPs and DNA repair active and therefore represents a novel target in ...

PARP1 condensates differentially partition DNA repair proteins and enhance DNA ligation

EMBO Reports
Poly(ADP-ribose) polymerase 1 (PARP1) is one of the first responders to DNA damage and plays crucial roles in recruiting DNA repair proteins through its activity – poly(ADP-ribosyl)ation (PARylation). The enrichment of DNA repair proteins at sites of DNA

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 ...

Newly identified human aminoacyl‐tRNA synthetase complex interacting multifunctional protein 2 (AIMP2) loss‐of‐function mutations cause neurodevelopmental defects linked to cell death in a zebrafish model

The FEBS Journal, EarlyView.
Human AIMP2 mutations lead to severe neurodevelopmental defects and brain atrophy. Using patient‐derived fibroblasts from two individuals, we show decreased AIMP2 protein levels and overall protein synthesis. In a zebrafish loss‐of‐function model, the lack of AIMP2 leads to an increase in cell death and results in smaller brains.
