An engineered epididymal cell line provides a sustainable source of functional extracellular vesicles for in vitro sperm preservation: A multi‐omics and functional study

VIEW, EarlyView.
ABSTRACT This study investigated the function of epididymal extracellular vesicles (EVs) in overcoming sperm post‐testicular modification deficiencies. Although EVs derived from the epididymis play a crucial role in intercellular communication and molecular exchange, there is limited research addressing how EVs released by in vitro cultured epididymal ...

Anti-cancer Effects of a Chemically Modified miR-143 on Bladder Cancer by Either Systemic or Intravesical Treatment

Molecular Therapy: Methods & Clinical Development, 2019
We developed a novel chemically modified miR-143 (miR-143#12), and with it we investigated the contribution of miR-143 to the pathogenesis of bladder cancer (BC), in which miR-143 is extremely downregulated.

Slow Transit Constipation: Pathophysiological Perspectives and Management Updates

Journal of Digestive Diseases, EarlyView.
Slow transit constipation (STC) is a complex neuromuscular disorder driven by interstitial cells of Cajal (ICCs) loss and enteric neuropathy. Diagnosis relies on objective transit testing while excluding pelvic floor dysfunction. Management follows a stepwise, phenotype‐driven approach, progressing from conventional laxatives to emerging targeted ...

A phased-addition strategy enhances the yield of RNAs obtained by in vitro transcription with modified transcriptional initiators [PDF]

, 2015
RNA is active in multiple biological processes, not only as an information carrier but in catalyzing reactions and regulating gene expression. To understand the basis for this versatility, it is critical to establish structure-function relationships in ...

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.

Non‐canonical PKG1 regulation in cardiovascular health and disease

British Journal of Pharmacology, EarlyView.
It is well established that the cyclic GMP‐dependent protein kinase I (PKG1) is canonically activated by cyclic guanosine monophosphate (cGMP), enabling its regulation of vascular tone, cardiac function and smooth muscle homeostasis. However, diverse non‐canonical stimuli of PKG1 have also been identified.

Salvage enzymes in nucleotide biosynthesis [PDF]

, 2007
Balanced pools of deoxyribonucleoside triphosphates (dNTPs), the building blocks of DNA, and ribonucleoside triphosphates (NTPs), the precursors of RNA, are crucial for a controlled cell proliferation.

An intracellular recombinant single‐chain variable antibody fragment as a new class of phosphodiesterase type 5 inhibitors

British Journal of Pharmacology, EarlyView.
Background and Purpose Cyclic guanosine monophosphate (cGMP) is a ubiquitous second messenger involved in human (patho‐)physiology. Phosphodiesterase 5 (PDE5) is a major cGMP hydrolyzing enzyme in many cell types including vascular smooth muscle cells (VSMCs). Several highly selective PDE5 inhibitors are in clinical use. However, there are currently no
