Resumen
La esclerosis tuberosa es un trastorno genético que causa tumores en múltiples órganos debido a mutaciones en los genes TSC1 y TSC2. Comprender estos cambios moleculares es clave para manejar los casos graves y mejorar los resultados de los pacientes.
Área de la Ciencia:
- Genética La genética.
- Biología Molecular Biología Molecular
- Ciencias Médicas Ciencias Médicas.
Sus antecedentes:
- La esclerosis tuberosa es un trastorno multisistémico genético caracterizado por hamartomas en órganos como el cerebro, el corazón, la piel y los riñones.
- Es causada por mutaciones en los genes TSC1 y TSC2, que codifican el hamartín y la tuberina.
- El complejo hamartin-tuberina normalmente inhibe la vía mamífero-objetivo-de-rapamicina (mTOR), crucial para el crecimiento celular.
Objetivo del estudio:
- Para resumir la base genética y las manifestaciones clínicas de la esclerosis tuberosa.
- Para resaltar el papel de la vía TSC1/TSC2-hamartin-tuberin-mTOR. para resaltar el papel de la vía TSC1/TSC2-hamartin-tuberin-mTOR. para resaltar el papel de la vía TSC1/TSC2-hamartin-tuberin-mTOR. para resaltar el papel de la vía TSC1/TSC2-hamartin-tuberin-mTOR.
- Para enfatizar la necesidad de la identificación temprana de los pacientes en riesgo de enfermedad grave.
Principales métodos:
- Revisión de la literatura existente sobre la genética de la esclerosis tuberosa y la presentación clínica.
- Análisis de los mecanismos moleculares que involucran a TSC1, TSC2 y la vía mTOR.
- Discusión de los desafíos de diagnóstico y la importancia de la estratificación del riesgo.
Principales resultados:
- La esclerosis tuberosa es el resultado de mutaciones genéticas que afectan a la regulación del crecimiento celular.
- La presentación clínica varía ampliamente debido a la distribución de la lesión y factores genéticos.
- Los métodos de diagnóstico actuales están limitados para la detección temprana, ya que los síntomas aparecen después de los tres años.
Conclusiones:
- Comprender la base molecular de la esclerosis tuberosa es esencial para el desarrollo de terapias dirigidas.
- La identificación temprana de las personas en riesgo es fundamental para el manejo de las manifestaciones graves.
- Una mayor investigación sobre las anomalías moleculares puede conducir a mejores estrategias de manejo de la enfermedad.

01:22Microtubules in Signaling
The primary cilium, made up of microtubules, acts as antennae on the cell surfaces for relaying external stimuli into the cells. These fine hair-like structures are present, generally one per cell. These are non-motile cilia in a 9+0 microtubules arrangement, where the central pair of microtubules are absent. The primary cilia arise from the basal body embedded in the cell membrane. Intraflagellar transport (IFT) carries requisite proteins from the cytoplasm to the cilium because the primary...
03:03mTOR Signaling and Cancer Progression
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

01:22PI3K/mTOR/AKT Signaling Pathway
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a rapamycin-insensitive companion...
01:21Huntington Disease l: Introduction
Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show reduced penetrance,...
01:20The Retinoblastoma Gene
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

01:31Pulmonary Tuberculosis III
Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:
