Drugs Affecting 5-HT Systems [PDF]

open access: yes, 2013
Seminar transcriptIt was in the very early hours of a February morning in 1977 that I first looked down the microscope and saw yellow fluorescence, characteristic of 5-hydroxytryptamine (5-HT) in frozen sections of Octopus brain. After struggling for two

Neurotransmitter profile of saccadic omnipause neurons in nucleus raphe interpositus [PDF]

open access: yes, 1994
Saccadic omnipause neurons (OPNs) are essential for the generation of saccadic eye movements. In primates OPNs are located near the midline within the nucleus raphe interpositus (rip).

The Effects of Serotonin on Functionally Diverse Isolated Lamprey Spinal Cord Neurons [PDF]

open access: yes, 2002
The experiments reported here showed that application of serotonin (5-hydroxytryptamine, 5-HT) (100 µ M) did not induce any significant current through the membranes of any of the spinal neurons studied (n = 62).

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

open access: yesFEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Quinine blocks 5-HT and 5-HT3 receptor mediated peristalsis in both guinea pig and mouse ileum tissue [PDF]

open access: yes, 2011
Introduction. Quinine is commonly used to treat malaria; however one of the principal side effects is gastrointestinal disturbances (White, 1992). 5-HT3 receptors modulate gut peristalsis (Chetty et al., 2006), and, as quinine has been shown to act as a ...

Discriminating depression, physical and social anhedonia by neurotransmitter related challenge tests [PDF]

open access: yes, 2016
The aim of this study was to investigate, if anhedonia, a salient component of depression, shows similar response patterns to neurotransmitter challenge tests as depression, and if the two questionnaire based components Physical (PA) and Social (SA ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Patch-to-Seq and Transcriptomic Analyses Yield Molecular Markers of Functionally Distinct Brainstem Serotonin Neurons

open access: yesFrontiers in Synaptic Neuroscience, 2022
Acute regulation of CO2 and pH homeostasis requires sensory feedback from peripheral (carotid body) and central (central) CO2/pH sensitive cells – so called respiratory chemoreceptors.

A role for antizyme inhibitor 2 in the biosynthesis and content of serotonin and histamine in mouse mast cells [PDF]

open access: yes, 2015
Polyamines (putrescine, spermidine and spermine; PAs) are essential for the majority of living cells. Antizymes and antizyme inhibitors are key regulatory proteins of PA levels by affecting ornithine decarboxylase and PA uptake.

PARP inhibition and pharmacological ascorbate demonstrate synergy in castration‐resistant prostate cancer

open access: yesMolecular Oncology, EarlyView.
Pharmacologic ascorbate (vitamin C) increases ROS, disrupts cellular metabolism, and induces DNA damage in CRPC cells. These effects sensitize tumors to PARP inhibition, producing synergistic growth suppression with olaparib in vitro and significantly delayed tumor progression in vivo. Pyruvate rescue confirms ROS‐dependent activity.
