Resumen
Las modificaciones postraslacionales (PTM) regulan la fertilidad de los mamíferos mediante el control de las interacciones celulares ováricas y la remodelación epigenética. La comprensión de las PTM es crucial para abordar enfermedades reproductivas como el SOP y la IOP.
Área de la Ciencia:
- Biología de la reproducción
- Endocrinología molecular
- La bioquímica
Sus antecedentes:
- Las modificaciones postraslacionales (PTM) son fundamentales para regular el desarrollo folicular y la fertilidad de los mamíferos.
- La desregulación de las PTM está implicada en trastornos reproductivos como el síndrome de ovario poliquístico (SOP) y la insuficiencia ovárica prematura (IOP).
Objetivo del estudio:
- Revisar sistemáticamente los avances recientes en las PTM implicadas en el desarrollo folicular.
- Construir un panorama completo de las PTM, incluidas las modificaciones tradicionales y emergentes.
- Para diseccionar las redes PTM y su papel en las patologías ováricas.
Principales métodos:
- Revisión sistemática de la literatura sobre las PTM en el desarrollo folicular.
- Análisis de las redes de interacción molecular de las PTM durante los procesos ováricos clave (activación, maduración, ovulación).
- Investigación de los mecanismos de desregulación de la PTM en el síndrome de ovario poliquístico y la IOP.
Principales resultados:
- Se han sintetizado PTM tradicionales (fosforilación, ubiquitinación, acetilación) y PTM emergentes (lactilación, SUMOilación, ISGilación).
- Redes PTM disecadas que gobiernan la activación folicular, la maduración y la ovulación.
- Se han identificado vías comunes de desregulación de la PTM que contribuyen al hiperandrogenismo en el síndrome de ovario poliquístico y al agotamiento folicular en la IOP.
Conclusiones:
- Los PTM son reguladores críticos de la función ovárica y la fertilidad.
- Comprender las PTM proporciona información sobre la patogénesis de las enfermedades reproductivas.
- Esta revisión ofrece una base teórica para mejorar la reproducción del ganado y el tratamiento de los trastornos ováricos humanos.

01:20Folliculogenesis
1.1K
Folliculogenesis is the development of ovarian follicles, the specialized structures within the ovarian cortex where oogenesis, or egg development, occurs. This process is essential for female reproductive health and begins during fetal development when primordial follicles are formed. Each primordial follicle comprises a primary oocyte in the center, surrounded by a single layer of squamous pre-granulosa cells. These follicles remain dormant in late prophase I of meiosis until triggered by...

02:07Oogenesis
64.4K
In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...

01:30Hormonal Control of the Ovarian Cycle
2.7K
The ovarian cycle is meticulously regulated by the hypothalamic-pituitary-gonadal axis. This cycle orchestrates the release of a mature oocyte, essential for reproduction.
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...

01:27Ovarian Cycle
1.8K
The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle...

01:22Hormonal Regulation of the Menstrual Cycle
690
The ovarian cycle regulates endometrial changes throughout a single menstrual cycle via the coordinated action of gonadotrophin-releasing hormone (GnRH) and gonadotrophins.
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...

01:23Regulation of Expression at Multiple Steps
996
The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the...
