Seminal Plasma Exosomal miRNA Profiling Reveals hsa‐miR‐7‐5p as a Key Regulator of Sperm Motility in Asthenozoospermia

Andrology, EarlyView.
ABSTRACT Background Asthenozoospermia is a significant contributing factor to male infertility. Accumulating evidence indicates that impaired sperm motility is closely linked to dysregulated microRNA expression during spermatogenesis. Seminal plasma exosomes are enriched with diverse microRNAs, which play pivotal roles in modulating sperm motility, the

Compartmentalisation in cAMP signalling: A phase separation perspective

British Journal of Pharmacology, EarlyView.
Cells rely on precise spatiotemporal control of signalling pathways to ensure functional specificity. The compartmentalisation of cyclic AMP (cAMP) and protein kinase A (PKA) signalling enables distinct cellular responses within a crowded cytoplasmic space.

Notoginsenoside‐Fa mitigates vascular endothelial permeability via targeting SUGT1 to stabilize NLRP3 in a resting state

British Journal of Pharmacology, EarlyView.
Background and Purpose Notoginsenoside‐Fa (Noto‐Fa) is an emerging active compound derived from notoginseng with promise in treating cardiovascular diseases. The development of cardiovascular diseases is intricately linked to the damage of vascular endothelium and it is widely acknowledged that numerous chronic inflammation pathways, especially the ...

A Curcumin‐Derived HSP70 Inhibitor Disrupts Lysosomal Function to Suppress Triple‐Negative Breast Cancer Progression

Cell Proliferation, EarlyView.
Novel curcumin‐derived M4 binds HSP70's ATPase domain, disrupting HSP70‐mediated lysosomes‐autophagy pathway to inhibit TNBC growth and metastasis, and synergizes with paclitaxel for potent combination therapy. ABSTRACT Structural modification of curcumin yielded a novel series of 1,4‐pentadien‐3‐one oxime ether derivatives, among which compound M4 ...

Periodontitis‐Associated Circulating EVs Promote Colorectal Cancer Progression via Carnosine‐Mediated Acidosis Adaptation

Cell Proliferation, EarlyView.
This study identifies a link between periodontitis and CRC progression mediated by carnosine‐enriched circulating EVs. These EVs target the intestine and elevate tumour cell intracellular pH (pHi), which rescues lysosomal function. This process drives a transition from dysfunctional lysosomes to functional ones, promoting a high malignancy phenotype in

Hypercortisolism: Causes, Consequences and Clinical Significance – A Review of Pathophysiology

Diabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Hypercortisolism or Cushing syndrome is a heterogeneous clinical spectrum caused by chronic glucocorticoid excess, ranging from exogenous Cushing syndrome to rare endogenous aetiologies and the increasingly recognised entity of mild autonomous cortisol secretion (MACS). Physiological cortisol production is tightly regulated by the hypothalamic–

Proteostasis of organelles in aging and disease

The FEBS Journal, EarlyView.
Cells rely on regulated proteostasis mechanisms to keep their internal compartments functioning properly. When these mechanisms fail, damaged proteins accumulate, disrupting organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi, and lysosomes, as well as membraneless organelles, such as stress granules, processing bodies, the ...

Biogenesis of TNF‐α‐insights into proteostasis and inflammation

The FEBS Journal, EarlyView.
TNF‐α biogenesis, trafficking, and signalling are tightly and reciprocally coupled to cellular proteostasis systems, including ER chaperones and endoplasmic reticulum‐associated degradation. This bidirectional crosstalk determines whether TNF‐α responses are adaptive or proteotoxic.

Combating ageing beyond the cell: Emerging roles of extracellular proteostasis

The FEBS Journal, EarlyView.
Ageing challenges the body's ability to maintain a stable and functional proteome, leading to protein damage and aggregation both inside and outside cells. This review focuses on the less well understood mechanisms of extracellular protein quality control and how they become disrupted in ageing, particularly in neurodegenerative diseases.

Chronic thermal stress affects growth, liver morphology and molecular responses but allows recovery at optimal temperature in juvenile zebrafish (Danio rerio)

Journal of Fish Biology, EarlyView.
Abstract Climate‐driven aquatic heatwaves pose an increasing threat to fish populations by inducing prolonged thermal stress. However, the resilience of teleosts to chronic heat exposure and their capacity for recovery remains poorly understood. This study investigated the effects of chronic high‐temperature exposure on juvenile zebrafish (Danio rerio).
