Resumen
Los elementos transponibles (TE) y el ADN circular extracromosómico (eccDNA) están implicados en la patogénesis de la diabetes tipo 2 (T2D) y el envejecimiento. La comprensión de estos factores genéticos puede conducir a nuevas estrategias de prevención de la T2D.
Área de la Ciencia:
- Genética
- Enfermedades Metabólicas
- Biología Molecular
Sus antecedentes:
- La diabetes tipo 2 (T2D) resulta de complejas interacciones genéticas y ambientales.
- Los elementos transponibles (TE) y el ADN circular extracromosómico (eccDNA) están relacionados con el envejecimiento celular y la disfunción metabólica.
- Aunque distintos, el eccDNA puede originarse a partir de TE, lo que sugiere mecanismos compartidos o relacionados.
Objetivo del estudio:
- Revisar el conocimiento actual sobre TE y eccDNA en T2D.
- Examinar la asociación entre T2D y TE o eccDNA.
- Destacar su papel en el envejecimiento y su potencial como biomarcadores de T2D.
Principales métodos:
- Revisión de literatura de estudios sobre TE, eccDNA y T2D.
- Análisis de asociaciones reportadas y conocimientos mecanicistas.
- Síntesis de hallazgos sobre patogénesis de enfermedades y envejecimiento.
Principales resultados:
- La activación de TE y la producción de eccDNA están implicadas en el desarrollo de T2D.
- Estos elementos genéticos se asocian con procesos de envejecimiento celular.
- La evidencia sugiere vías distintas pero potencialmente superpuestas que involucran TE y eccDNA en la T2D.
Conclusiones:
- Los TE y el eccDNA desempeñan un papel importante en la patogénesis de la T2D, especialmente en lo que respecta al envejecimiento.
- Estas moléculas muestran promesa como biomarcadores potenciales para el riesgo de T2D.
- La focalización de TE y eccDNA podría ofrecer nuevas vías para la prevención de la T2D.

13.1K
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...

01:22Diabetes Mellitus: Type 2 and Gestational
4.2K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

03:08LTR Retrotransposons
19.4K
LTR retrotransposons are class I transposable elements with long terminal repeats flanking an internal coding region. These elements are less abundant in mammals compared to other class I transposable elements. About 8 percent of human genomic DNA comprises LTR retrotransposons. Some of the common examples of LTR retrotransposons are Ty elements in yeast and Copia elements in Drosophila.

02:13Overview of Transposition and Recombination
18.7K
Transposons make up a significant part of genomes of various organisms. Therefore, it is believed that transposition played a major evolutionary role in speciation by changing genome sizes and modifying gene expression patterns. For example, in bacteria, transposition can lead to conferring antibiotic resistance. Movement of transposable elements within the genetic pool of pathogenic bacteria can aid in transfer of antibiotic-resistant genetic elements. In eukaryotes, transposons can carry out...

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

02:57DNA-only Transposons
17.1K
DNA-only transposons are called autonomous transposons since they code for the enzyme transposase that is required for the transposition mechanism. Insertion of transposons can alter gene functions in multiple ways. They can mutate the gene, alter gene expression by introducing a novel promoter or insulator sequence, introduce new splice sites, and change the mRNA transcripts produced, or remodel chromatin structure.
