Arf GTPases Define BST-2-Independent Pathways for HIV-1 Assembly and Release

Viruses
ADP-ribosylation factor (Arf) proteins are small GTPases that regulate intracellular membrane trafficking and actin remodeling through tightly controlled cycles of GTP binding and hydrolysis.

Phosphorylation of BigH1 regulates its expression pattern and promotes embryonic development

The FEBS Journal, EarlyView.
Phosphorylation is a key regulator of the linker histone variant BigH1 during Drosophila embryogenesis. We reveal that N‐terminal phosphorylation promotes the timely removal of BigH1 from chromatin. In contrast, C‐terminal phosphorylation supports early nuclear divisions and embryonic viability.

Structural and functional analysis of serine-ADP-ribosylation [PDF]

, 2018
ADP-ribosylation is a protein post-translational modification involved in several biological pathways, including the DNA damage response. PARP1, one of the primary sensors of DNA breaks, and the main enzyme responsible for ADP-ribosylation has been the ...

Auxin‐related regulation of barley floral organ fate: genetic and phenotypic insights from tweaky spike mutants

New Phytologist, EarlyView.
Inflorescence/floret phenotypes of tweaky spike (tw) barley (Hordeum vulgare) mutants and their respective WT backgrounds. Summary Mutant‐based research is a cornerstone for elucidating gene function in barley (Hordeum vulgare) and other cereals. In this study, we exploited a unique collection of barley tweaky spike (tw) mutants to identify the locus ...

Cannabinoid exposure during pregnancy: Cardiorespiratory effects and offspring outcomes

The Journal of Physiology, EarlyView.
Abstract figure legend Prenatal exposure to cannabinoids has been investigated across human and animal studies to understand its impact on physiological development. Evidence suggests that early‐life cannabinoid exposure influence multiple developmental processes, extending beyond neurodevelopmental outcomes to potentially affect placental function ...

Maternal protein restriction programs the ageing kidney: Proteomic signatures of early‐life origin renal and metabolic dysfunction

The Journal of Physiology, EarlyView.
Abstract figure legend Maternal protein restriction (MPR) induced persistent renal histopathological alterations accompanied by elevated serum creatinine levels. Nephron‐segment proteomic analysis revealed region‐specific molecular dysregulation affecting Bowman's capsule (PARK7, oxidative stress sensor; MSN, cytoskeletal organization), the proximal ...

Orchestrating the metastatic symphony: the role of extracellular vesicles in the epithelial–mesenchymal transition and pulmonary niche formation of breast cancer

Biological Reviews, Volume 101, Issue 5, Page 2103-2118, October 2026.
ABSTRACT The complexity of breast cancer (BC) lung metastasis lies in the capacity of tumour cells to interact efficiently with distant organs to promote colonisation, a process that involves the sophisticated coordination of inherent cellular plasticity and the remodelling of the distant microenvironment.

Extracellular Vesicles: Classification, Biological Functions, Diseases, and Therapeutic Opportunities

MedComm, Volume 7, Issue 10, October 2026.
• EV content maintains cellular homeostasis and is involved in several disease onset and progression. • miRNA export in EVs depends on: RNA‐binding proteins recognizing motif sequences and on epitranscriptomic modifications. • The disclosure of delivery mechanisms is crucial for developing personalized EV‐based therapeutic tools. ABSTRACT Extracellular

Aging of Skeletal Muscle: From Molecular Mechanisms to Therapeutic Interventions

MedComm, Volume 7, Issue 10, October 2026.
Skeletal muscle aging is driven by coordinated local breakdown across myofibers, stem and stromal cells, immune and vascular compartments, and neuromuscular control. These mechanisms promote mitochondrial dysfunction, inflammation, senescence, impaired regeneration, fibrosis, myosteatosis, denervation, and functional decline.

Biochemical and Developmental Characterization of ADP-ribosylation Factors, A Family of 20 kDa Guanine Nucleotide-binding Proteins

The cholera toxin A subunit (CT-A) is an ADP-ribosyltransferase; its principal cellular substrates are the α subunits of Gs, the stimulatory G protein of adenylyl cyclase.
