Resumen
La expresión génica de las muestras de sangre puede predecir el tiempo circadiano, ayudando a la cronoterapia. Esta herramienta ayuda a optimizar el tiempo de tratamiento para una mejor eficacia y menos efectos secundarios en adultos con sueño corto.
Área de la Ciencia:
- Cronología
- Biología molecular
- Medicina del sueño
Sus antecedentes:
- La cronoterapia optimiza el tiempo de tratamiento para mejorar la eficacia y reducir los efectos secundarios.
- La adopción generalizada de la cronoterapia está limitada por la falta de herramientas accesibles para determinar el tiempo circadiano.
- Los perfiles de expresión génica muestran potencial para predecir el tiempo circadiano.
Objetivo del estudio:
- Evaluar la asociación entre las predicciones de la fase circadiana de una sola muestra de sangre, el sueño estimado por actigrafía y el cronotipo.
- Evaluar la utilidad de la expresión génica de las células mononucleares de la sangre periférica para estimar la fase circadiana en un entorno real.
Principales métodos:
- Doce adultos con sueño corto y con riesgo de síndrome metabólico participaron.
- La secuenciación del ARN se realizó en monocitos CD14+ aislados de muestras de sangre.
- El sueño fue monitoreado utilizando ActiGraph, y el cronotipo fue evaluado con la Escala Compuesta de Morningness.
Principales resultados:
- Se encontraron asociaciones moderadas a fuertes entre la aparición de melatonina basada en la expresión génica (DLMO) y el sueño estimado por actigrafía.
- Los perfiles de expresión génica de las células mononucleares de la sangre periférica demostraron su utilidad en la estimación de la fase circadiana.
Conclusiones:
- El perfil de expresión génica de una sola muestra de sangre es prometedor para estimar la fase circadiana.
- Este enfoque puede mejorar la implementación de la cronoterapia en adultos de mediana edad con enfermedades crónicas y sueño corto.

02:19Circadian Rhythms and Gene Regulation
4.1K
The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent...

The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.

Circadian rhythms are cyclic changes that are crucial in plasma drug concentrations. Various standard circadian parameters, including core body temperature, heart rate, and other cardiovascular factors, directly impact disease states and the therapeutic response to drug therapy.
The time of drug administration is an important factor to consider, as it can influence the toxic dose of a drug. For example, a study conducted by Prins et al. in 1997 examined the effects of the timing of...

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...

02:27Background and Environment Affect Phenotype

Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

01:11Understanding Sleep

Sleep, an essential biological state, involves significant reductions in physical activity, sensory awareness, and interaction with the environment. This complex physiological process is primarily regulated by specific brain regions, notably the hypothalamus and pons, which govern the sleep-wake cycle or circadian rhythm.
The circadian rhythm, a nearly 24-hour cycle, is deeply influenced by environmental light cues. Light exposure directly affects the hypothalamus, which in turn regulates...
