El sistema circadiano controla la liberación de esperma en los testículos de los insectos
Resumen
El testículo de la mariposa gitana controla la liberación de esperma rítmicamente, persistiendo incluso en cultivos de laboratorio. Este descubrimiento revela un nuevo modelo para el estudio de los ritmos circadianos en organismos multicelulares.
Área de la Ciencia:
- Cronobiología cronobiología.
- Biología Reproductiva Biología Reproductiva.
- Fisiología de los insectos.
Sus antecedentes:
- Los ritmos circadianos regulan los procesos fisiológicos en muchos organismos.
- Los mecanismos celulares que subyacen a los ritmos circadianos no se comprenden completamente.
- Las funciones reproductivas a menudo están influenciadas por los ritmos diarios.
Objetivo del estudio:
- Para investigar la presencia y la naturaleza del control circadiano sobre la liberación de esperma en la polilla gitana.
- Para determinar si el complejo de conductos testículo-seminal es fotosensible y contiene un marcapasos circadiano.
- Establecer un nuevo sistema modelo para el estudio de los mecanismos circadianos en organismos multicelulares.
Principales métodos:
- Cultivo in vitro de complejos aislados de conductos seminales testículo-seminal de la mariposa gitana.
- Exposición de tejidos en cultivo a ciclos controlados de luz-oscuridad y oscuridad constante.
- Observación y análisis de los patrones de liberación de esperma bajo diferentes condiciones de luz.
Principales resultados:
- La liberación de esperma del testículo de la mariposa gitana exhibe un ritmo circadiano persistente.
- El ritmo se mantuvo in vitro bajo ciclos de luz-oscuridad y oscuridad constante.
- La exposición a ciclos de luz-oscuridad cambiados restablece con éxito la fase del ritmo.
Conclusiones:
- El complejo de conducto seminal-testículo de la mariposa gitana es fotosensible y posee un marcapasos circadiano intrínseco.
- Este marcapasos controla directamente el ritmo del movimiento de los espermatozoides.
- Los hallazgos introducen un nuevo sistema de modelos para investigar los osciladores circadianos en la vida multicelular.

Circadian Rhythms and Gene Regulation
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 years,...
The Ratio of X Chromosome to Autosomes
In most organisms, sex is determined by the ratio of X and Y chromosomes. However, in some organisms, such as Drosophila and C.elegans, sex is determined by the ratio of the number of X chromosomes to the number of sets of autosomes. The Y chromosome in Drosophila is active but does not determine sex. It contains genes responsible for the production of sperms in adult flies.
Normal male Drosophila has a ratio of one X chromosome to two sets of autosomes. In contrast, normal female Drosophila...

Testosterone: Functions and Regulation
The intricate hormonal interplay essential for male reproductive health begins with the release of gonadotropin-releasing hormone (GnRH) by the hypothalamus. This hormone prompts the pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). LH targets the Leydig cells in the testes, stimulating them to produce and release testosterone. In concert with testosterone, FSH acts on the Sertoli cells within the seminiferous tubules to facilitate the release of...
Sperm Transport
The journey of sperm from its origin to the point of ejaculation begins within the seminiferous tubules of the testis. Here, Sertoli cells produce fluid that propels non-motile sperm through a series of conduits, starting with the straight tubules leading to the rete testis. This interconnected network of tubules acts as the initial pathway for sperm, guiding them into the efferent ductules and then into the epididymis for maturation.
The maturation phase occurs in the epididymis, where sperm...

Feedback Regulation of Calcium Concentration
Calcium is an essential signaling molecule required for various cellular functions. Calcium pumps and ion channels on cell and organellar membranes, such as those on the endoplasmic reticulum (ER), regulate calcium concentrations inside the cell. They remain closed, keeping the cytosolic calcium levels low at a resting state.
Various transmembrane receptors, such as G protein-coupled receptors (GPCRs), elicit a response to extracellular signals by increasing cytosolic calcium. Activated GPCRs...
