Endogenous 5-HT exerts a dual role in the pathogenesis of indomethacin-induced intestinal lesions: pro-ulcerogenic action via 5-HT3 receptors and anti-ulcerogenic action via 5-HT4 receptors.
This review presented that the 5HT4 RECEPTOR knockout mice show a correlation between 5-HT firing rate and depressive/resilience phenotypes.
These results show that prenatal stress and reduced 5-HT levels can alter 5-HT(4)R expression in the developing forebrain and that some 5-HT(4)R splice variants.
This study demonistrated that alternatively spliced multiple transcripts of 5-hydroxytryptamine receptor expression in heart.
Mucosal 5-HT(4) receptor activation can mediate the prokinetic and antinociceptive actions of 5-HT(4)R agonists.
Data indicate that most p11 expressing cells in cerebral cortex, hippocampus, cerebellum, & caudate-putamen express HTR1B or co-express HTR1B/HTR4, suggesting crucial role for p11 in modulating actions of serotonin via these receptor subtypes.
The 5-HT4 receptor seem to be particularly involved in antigen-induced airway hyperresponsiveness(AI-AHR) to ACh in guinea-pigs.
Overexpression of G-protein-coupled receptor HTR4 in rod cells affects the glycosylation pattern of coexisting native rhodopsin.
analysis of eight bovine 5-HT receptor subtypes in brain, abomasum, and intestine by real-time RT-PCR
found that testosterone, but not estradiol, correlated negatively with global 5-HT4R levels suggesting that men with high levels of testosterone have higher cerebral serotonergic tonus.
l-Lysine significantly reduced the surge of plasma aldosterone induced by metoclopramide indicating that l-Lysine is able to efficiently antagonize the adrenal 5-HT4 receptors in vivo.
Acute administration of 5-hydroxytryptamine4 (5-HT4) receptor agonist, mosapride or esophageal infusion of the transient receptor potential vanilloid receptor-1 (TRPV1) agonist capsaicin promotes secondary peristalsis.Esophageal infusion with capsaicin-containing red pepper sauce suspension does create greater mechanosensitivity as measured by secondary peristalsis than 5-HT4 receptor agonist mosapride
Findings replicate our previous observation of a negative association between 5-HT 4R binding and memory performance in an independent cohort and provide novel evidence linking 5-HT 4R binding, as a biomarker for synaptic 5-HT levels, to the mnestic processing of positive and neutral word stimuli in healthy humans
Results of this study indicated that HTR4 signaling upregulated ERbeta expression in hormone-naive prostate cancer and could impact on biological processes in hormone-naive prostate cancer.
Data suggest that the 5-HT4 receptor is involved in the neurobiological mechanism underlying familial risk for depression, and that lower striatal 5-HT4 receptor binding is associated with increased risk for developing major depression disorder
PDE3A1 and PDE4D3 are integrated into complexes that contain the 5-HT4(b) receptor and may thereby regulate 5-HT4(b) receptor-mediated signaling.
This study demonistrated that 5-hydroxytryptamine (serotonin) receptor 4 regulate memory.
ADAM19 rs1422795 and HTR4 rs11168048 are associated with pulmonary function.

Stimulation of central 5-HT4 receptors is potentially disease-modifying in a transgenic mouse model of Alzheimer's disease.
Taken together, these data suggest a role for HTR4 in lung development, which may at least in part explain the genetic association with lung function.
Our results suggest that HTR4 polymorphisms may not play a major role in the susceptibility for suicidal behavior in subjects with schizophrenia.
Results suggest an important role for the CHRNA5/3 region as a genetic risk factor for airflow obstruction independent of smoking and implicate the HTR4 gene in the etiology of airflow obstruction.
Our findings are consistent with a model wherein the 5-HTTLPR S allele is associated with relatively increased serotonin levels.
These findings suggest that the 5-HT(4)R is critically involved in reward circuits that regulate people's food intake
staining pattern of serotonin receptors in ovary indicates functional role in ovarian physiology. In ovarian tumours, expression is in harmony with a tumour suppressor role in ovarian carcinogenesis, which is supported by observations in the literature
neurogenic excitatory and inhibitory motor responses and role of 5-HT(4) receptors in circular smooth muscle
The identification of nine novel COOH-terminal splice variants of the porcine 5-HT(4) receptor, is reported.
This gene is a member of the family of serotonin receptors, which are G protein coupled receptors that stimulate cAMP production in response to serotonin (5-hydroxytryptamine). The gene product is a glycosylated transmembrane protein that functions in both the peripheral and central nervous system to modulate the release of various neurotransmitters. Multiple transcript variants encoding proteins with distinct C-terminal sequences have been described.
