Summary
This study identifies EP300 as a lactylation-related gene linked to insomnia. EP300 may promote insomnia by affecting immune cells, offering a potential new therapeutic target for sleep disorders.
Area of Science:
- Genetics
- Sleep Medicine
- Immunology
Background:
- Insomnia is a common disorder influenced by multiple factors.
- The role of lactylation-related genes in insomnia pathogenesis is not well understood.
Purpose of the Study:
- To investigate the causal relationship between lactylation-related genes and insomnia.
- To identify potential therapeutic targets for insomnia.
Main Methods:
- Mendelian randomization analysis using cis-expression quantitative trait loci (cis-eQTL) data.
- Validation through summary-data-based MR (SMR) and Gene Expression Omnibus (Geo) data analysis.
- Mediation analysis involving immune cells and EP300 gene expression.
Main Results:
- One lactylation-related gene, EP300, was significantly associated with insomnia.
- EP300 expression differed significantly between insomnia patients and healthy individuals.
- EP300 appears to promote insomnia by regulating CD8br AC (TBNK panel) immune cells.
Conclusions:
- EP300 is implicated in the pathogenesis of insomnia.
- EP300 represents a potential novel therapeutic target for insomnia treatment.

The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...

247
Sedatives and hypnotics encompass a wide range of substances, each with its unique mechanism of action, uses, and potential adverse effects.
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...

01:27Insomnia
132
Insomnia is a prevalent sleep disorder characterized by difficulty falling asleep, frequent awakenings during the night, and waking up too early without being able to return to sleep. People with insomnia often experience these disruptions at least three nights a week for at least one month. Chronic insomnia, which lasts for at least three months, can lead to increased anxiety, which in turn can worsen sleep difficulties, creating a cycle of sleeplessness and stress.

01:14CNS Depressants: Barbiturates and Benzodiazepines
478
CNS depressants include drugs from the category of barbiturates and benzodiazepines. They are valuable medications for managing anxiety disorders and insomnia. Barbiturates, once used to induce and maintain sleep, have been replaced mainly by benzodiazepines due to barbiturate's toxicity, tolerance, and overdose risks. They interact with GABAA receptors, leading to sedation at low doses and potentially coma and death at higher doses. Phenobarbital, a long-acting barbiturate, possesses...

01:24Substance Use Disorders Affecting Sleep
225
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
