The intestinal L cell is the principal source of glucagon-like peptide-1 (GLP-1), a major determinant of insulin release. Because GLP-1 secretion is regulated in a circadian manner in rodents, we investigated whether the activity of the human L cell is also time sensitive. Rhythmic fluctuations in the mRNA levels of canonical clock genes were found in the human NCI-H716 L cell model, which also showed a time-dependent pattern in their response to well-established secretagogues. A diurnal…

Circadian GLP-1 Secretion in Mice Is Dependent on the Intestinal Microbiome for Maintenance of Diurnal Metabolic Homeostasis
TLDR
A key role for microbiome-dependent circadian GLP-1 secretion in the maintenance of 24-h metabolic homeostasis is established and studies in antibiotic-induced microbial depleted and in germ-free mice with and without fecal microbial transfer, provide evidence for a role of the microbiome in diurnal GLp-1 release.
High-Fat Diet and Palmitate Alter the Rhythmic Secretion of Glucagon-Like Peptide-1 by the Rodent L-cell.
TLDR
Diurnal variations in GLP-1 and insulin nutrient-induced responses were maintained in animals lacking an endogenous corticosterone rhythm, suggesting that glucocorticoids are not the predominant entrainment factor for L-cell rhythmic activity.
Effects of Obesogenic Feeding and Free Fatty Acids on Circadian Secretion of Metabolic Hormones: Implications for the Development of Type 2 Diabetes
TLDR
The central focus of the review considers the circadian-disrupting effects of obesogenic feeding and palmitate exposure in L and β cells, while providing insight into the potential causative role in the development of metabolic disease.
The effect of melatonin on glucose tolerance, insulin sensitivity and lipid profiles after a late evening meal in healthy young males
TLDR
Exogenous melatonin administrated before an evening test meal improved glucose tolerance, insulin sensitivity and reduced postprandial TAGs, which could have implications for shift workers who may have lower melatonin levels at night due to light suppression.
L-cell Arntl is required for rhythmic glucagon-like peptide-1 secretion and maintenance of intestinal homeostasis
Glucagon‐like peptide‐1: The missing link in the metabolic clock?
TLDR
It is established that secretion of glucagon‐like peptide‐1 from the intestinal L cell shows a rhythmic pattern in rats and humans in vivo that is altered by circadian disruptors, and it is suggested that altered release of glucose‐dependent peptide-1 might play a role in the metabolic perturbations that result from circadian disruption.
The importance of melatonin in the regulation of metabolism, eating behavior, sleep, and the prospects for the use of melatonin drugs for obesity treatment
TLDR
According to this, the use of melatonin drugs for obesity treatment can be effective and prospective, controlled, randomized trials in this area are required to confirm this hypothesis.
A single night light exposure acutely alters hormonal and metabolic responses in healthy participants
TLDR
The impact of light on plasma hormones and metabolites prior to, and after, an evening meal in healthy participants may explain some of the health issues reported in shift workers; however, further studies are needed to elucidate the cause of these metabolic changes.
The core clock gene, Bmal1, and its downstream target, the SNARE regulatory protein secretagogin, are necessary for circadian secretion of glucagon-like peptide-1
The effects of light at night and/or melatonin on hormones, metabolites, appetite control, vascular function, and behavioural responses
TLDR
Two studies demonstrate a possible role for melatonin in glucose tolerance, insulin sensitivity and lipid metabolism when eating late at night which may have implications for shift-workers.

Circadian Secretion of the Intestinal Hormone GLP-1 by the Rodent L Cell
TLDR
It is demonstrated that an independent peripheral clock in the L cell drives a circadian rhythm in GLP-1 secretory responses to an oral glucose load in rats, with increased release immediately preceding the normal feeding period.
Modulation of glucose regulation and insulin secretion by circadian rhythmicity and sleep.
TLDR
The studies demonstrate previously underappreciated effects of circadian rhythmicity and sleep on glucose levels, insulin secretion, and insulin clearance, and suggest that these effects could be partially mediated by cortisol and growth hormone.
Disturbed glucoregulatory response to food intake after moderate sleep restriction.
TLDR
Data indicate an impairment of glucose tolerance after 2 days of sleep restriction to ~4 h that appears to be primarily caused by a reduction in insulin sensitivity, arguing against a mediation of these effects by stress-related or inflammatory mechanisms.
Glucagon-like peptide-1 (7-36)amide and glucose-dependent insulinotropic polypeptide secretion in response to nutrient ingestion in man: acute post-prandial and 24-h secretion patterns.
TLDR
The increases in circulating GLP-1(7-36)amide and GIP levels following carbohydrate or a mixed meal are consistent with their role as incretins, and the more sustained rises observed in the daytime during the 24-h study are inconsistent with an anabolic role in lipid metabolism.

TLDR
A reduction in amplitude of the SCN is sufficient to induce a complete loss of circadian rhythms in energy metabolism and insulin sensitivity, as well as abolishment of normal circadian variation in insulin sensitivity in LL.
A single night of partial sleep deprivation induces insulin resistance in multiple metabolic pathways in healthy subjects.
TLDR
Partial sleep deprivation during only a single night induces insulin resistance in multiple metabolic pathways in healthy subjects and may be of relevance for variations in glucoregulation in patients with type 1 and type 2 diabetes.
Consequences of Exposure to Light at Night on the Pancreatic Islet Circadian Clock and Function in Rats
TLDR
Exposure to LL leads to diminished glucose-stimulated insulin secretion due to a decrease in insulin secretory pulse mass, and potential mechanisms by which disturbances in circadian rhythms common to modern life can predispose to islet failure in T2DM are identified.
Sleep Restriction for 1 Week Reduces Insulin Sensitivity in Healthy Men
TLDR
Sleep restriction (5 h/night) for 1 week significantly reduces insulin sensitivity, raising concerns about effects of chronic insufficient sleep on disease processes associated with insulin resistance.
Glucagon-like peptide 1 has a physiological role in the control of postprandial glucose in humans: studies with the antagonist exendin 9-39.
TLDR
In humans exendin 9-39 acts as an antagonist of GLP-1 both in vitro and in vivo, suggesting that GLP the major physiological incretin in humans may be important for maintenance of normal postprandial glucose homeostasis in humans.
Effects of sleep deprivation and exercise on glucose tolerance.
TLDR
The results support the suggestion that SD results in decreased insulin sensitivity at peripheral receptor sites which can eventually lead to insulin exhaustion at pancreatic sites after longer periods of SD, and contributes to the development of an insulin resistance that can be partially reversed by physical activity.
