SCTR-Expressing Astrocyte-Serotonergic Neuron Signaling Drives Sexual Dimorphism in Depression Through KAT7/H4ac-Foxc2 Epigenetic Axis in an AMPK-Dependent Manner. [PDF]
Astrocytic SCTR modulates depressive‐related phenotypes via AMPKα1, whereas lowered Mt1 blunts Megalin‐dependent AMPKα2 signaling in serotonergic neurons. Diminished AMPKα2 hinders KAT7 nuclear translocation, curtails KAT7 occupancy and H4K8ac at the Foxc2 promoter, and represses Foxc2 transcription, revealing cell‐type‐specific AMPK‐linked epigenetic ...

Impaired Renal Base Excretion in Secretin Receptor Knock-Out Mice During Prolonged Base-Loading. [PDF]
ABSTRACT Aim Secretin was recently found to play a pivotal role in the renal adaptation to acute base excess. Here, secretin increases pendrin‐dependent HCO3− secretion from the beta‐intercalated cells in the cortical collecting ducts. Whether secretin and its receptor play a role during prolonged base‐loading remains unknown.

Disordered pancreatic and gastrointestinal hormone responses to nutrient stimulation in Zambian children with severe acute malnutrition. [PDF]
Abstract Nutrient sensing enables the body to detect and respond to nutrient availability through hormonal regulation. In this study, we examined nutrient‐stimulated hormonal responses in children with severe acute malnutrition (SAM) compared with hospitalized (HC) and community (CC) child comparators.

Fragment Coverage: Unified Visualization and Quantitative Assessment of MS/MS Fragmentation Supports Metabolite Identification in Macromolecule Drug Metabolism Studies. [PDF]
ABSTRACT Rationale Peptides and oligonucleotides are increasingly used as therapeutic agents, making the identification and structural elucidation of their metabolites a critical step in drug development. Liquid chromatography–mass spectrometry (LC‐MS/MS) is the primary analytical technique for this purpose; however, extensive backbone fragmentation ...

The Therapeutic Potential of Purmorphamine Across Disease Models. [PDF]
ABSTRACT Purmorphamine (PUR) is a trisubstituted purine compound that selectively activates Smoothened receptor, thereby initiating Sonic Hedgehog (Shh) signalling—a pathway critical for embryonic patterning, neuronal specification and tissue regeneration across multiple organ systems. Dysregulation of Shh signalling has been implicated in degenerative

Secretin interactions in the type II secretion system [PDF]
PhDThe type II secretion system (T2SS) is the major terminal branch of the general secretory pathway. It is composed of 12-15 proteins, most in multiple copies, and spans the inner and outer membranes of Gram-negative bacteria.

Identification and characterisation of calcitonin receptor isoforms expressed in glioblastoma derived glioma stem and U-87 MG cells. [PDF]
Glioblastoma cells express calcitonin receptor variants (CT receptor isoforms) that may help them survive stress. Using qPCR, transcript‐specific long‐read nanopore sequencing, immunofluorescence co‐localisation and comparative sequence analysis, this study identifies a novel alternatively spliced CALCR transcript that encodes the CTb receptor isoform ...

MOLECULAR EVOLUTION OF GPCRS: Secretin/secretin receptors [PDF]
In mammals, secretin is a 27-amino acid peptide that was first studied in 1902 by Bayliss and Starling from the extracts of the jejunal mucosa for its ability to stimulate pancreatic secretion. To date, secretin has only been identified in tetrapods, with the earliest diverged secretin found in frogs.

Intrinsic Disorder as a New Frontier in Antimicrobial Resistance and Bacterial Fitness [PDF]
The works examines the link between intrinsic disorder in bacterial protein structure, and bacterial function, and antimicrobial resistance. It highlights how flexible, disordered proteins support secretion, stress responses, desiccation protection, and virulence, while also suggesting that these adaptable regions may provide novel targets for ...
