Reestructuración del proto-oncogén en el cáncer de tiroides alrededor del sitio de pruebas nucleares de Semipalatinsk
Lancet (London, England)
|November 7, 1999
Resumen
El sitio de pruebas nucleares de Semipalatinsk en Kazajstán ha mostrado la primera evidencia de reorganización de proto-oncogenes reticulares en tejidos de cáncer de tiroides. Este hallazgo vincula las pruebas nucleares históricas con las alteraciones genéticas en los casos locales de cáncer de tiroides.
Área de la Ciencia:
- Oncología Oncología.
- Genética La genética.
- Salud Ambiental Salud del medio ambiente.
Sus antecedentes:
- El sitio de pruebas nucleares de Semipalatinsk en Kazajstán, URSS, fue el lugar de la primera explosión de dispositivo nuclear el 29 de agosto de 1949.
- Los sitios de pruebas nucleares pueden tener impactos ambientales y de salud a largo plazo en las poblaciones circundantes.
Objetivo del estudio:
- Para investigar posibles alteraciones genéticas en tejidos de cáncer de tiroides de individuos que residen cerca del sitio de pruebas nucleares de Semipalatinsk.
- Identificar cambios moleculares específicos, como reordenamientos genéticos, asociados con el cáncer de tiroides en esta población.
Principales métodos:
- Análisis de tejidos de cáncer de tiroides de pacientes en las cercanías del sitio de pruebas nucleares de Semipalatinsk.
- Técnicas moleculares para detectar reordenamientos genéticos, enfocándose específicamente en el ret proto-oncogén.
Principales resultados:
- El estudio presenta la primera evidencia de la reorganización del proto-oncogén reticular en tejidos de cáncer de tiroides de la región de Semipalatinsk.
- Esta reorganización es un hallazgo molecular significativo en los cánceres de tiroides relacionados con la exposición cerca de un sitio histórico de pruebas nucleares.
Conclusiones:
- Los hallazgos sugieren un posible vínculo entre las pruebas nucleares históricas en Semipalatinsk y las alteraciones genéticas en el cáncer de tiroides.
- Se requiere más investigación para comprender las implicaciones completas de la reorganización del proto-oncogén reticular en los cánceres de tiroides asociados con los sitios de pruebas nucleares.

03:18Non-LTR Retrotransposons
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...
02:53Conservative Site-specific Recombination and Phase Variation
Because the DNA segments are cut and reorganized in a direction-specific manner, site-specific recombination has emerged as an efficient genetic engineering technique. Flippase and Cyclization recombinases or Flp and Cre, respectively, are two members of the tyrosine recombinase family derived from bacteriophages, that are used to mediate site-specific DNA insertions, deletions, and targeted expression of proteins in mammalian cell lines.

01:33Cancer-Critical Genes I: Proto-oncogenes
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

01:24Graves Disease II: Pathophysiology
Graves’ disease is an autoimmune disorder characterized by the production of thyroid-stimulating immunoglobulins (TSI) that activate TSH receptors, leading to excessive synthesis and release of thyroid hormones (T3 and T4) and resulting in hyperthyroidism.Among all causes of hyperthyroidism, Graves’ disease is the most common and can happen at any age, though it is more frequent in women. It produces a hypermetabolic state with features such as weight loss, tachycardia, tremor, and heat...
