Resumen
Zanthoxylum armatum DC. ¿Qué es eso? extracto (ZADC-EA) causa daño hepático al inducir rupturas de doble cadena de ADN (DSB) y senescencia celular a través de la vía p53- p21. Este estudio proporciona información sobre el ZADC
Área de la Ciencia:
- Farmacología y Toxicología
- Biología molecular
- Química de los productos naturales
Sus antecedentes:
- Zanthoxylum armatum DC. ¿Qué es eso? (ZADC) se utiliza tradicionalmente, pero su perfil de seguridad requiere validación científica.
- La comprensión de los mecanismos moleculares de la toxicidad potencial de ZADC es crucial para su aplicación terapéutica.
Objetivo del estudio:
- Investigar los efectos hepatotóxicos del extracto de acetato de etilo ZADC (ZADC-EA).
- Para aclarar los mecanismos moleculares subyacentes de la lesión hepática inducida por ZADC, centrándose en el daño del ADN y la senescencia.
- Establecer una base científica para el uso seguro de ZADC.
Principales métodos:
- Perfilamiento químico de ZADC-EA mediante el uso de Q-Orbitrap LC-MS/MS.
- Evaluación del impacto de ZADC-EA en la viabilidad de las células HepG2, los marcadores de la función hepática y las citoquinas inflamatorias.
- Detección de rupturas de doble cadena de ADN (DSB) y senescencia celular mediante Western blot, RT-qPCR, citometría de flujo e inmunofluorescencia.
Principales resultados:
- ZADC-EA contiene flavonoides, ácidos orgánicos y cumarinas.
- La exposición a ZADC-EA redujo la viabilidad de las células HepG2 y aumentó los marcadores de daño hepático y los factores inflamatorios.
- El tratamiento con ZADC-EA indujo DSB y activó la vía p53-p21, lo que condujo a la senescencia celular.
Conclusiones:
- ZADC-EA induce daño hepático al causar rupturas de doble cadena de ADN (DSB).
- La vía de señalización p53-p21 es activada por ZADC-EA, lo que resulta en la senescencia celular.
- Esta investigación ofrece una nueva perspectiva sobre la evaluación de la seguridad de los ZADC.

Overview of DNA Repair
31.6K
In order to be passed through generations, genomic DNA must be undamaged and error-free. However, every day, DNA in a cell undergoes several thousand to a million damaging events by natural causes and external factors. Ionizing radiation such as UV rays, free radicals produced during cellular respiration, and hydrolytic damage from metabolic reactions can alter the structure of DNA. Damages caused include single-base alteration, base dimerization, chain breaks, and cross-linkage.

DNA Damage can Stall the Cell Cycle
9.3K
In response to DNA damage, cells can pause the cell cycle to assess and repair the breaks. However, the cell must check the DNA at certain critical stages during the cell cycle. If the cell cycle pauses before DNA replication, the cells will contain twice the amount of DNA. On the other hand, if cells arrest after DNA replication but before mitosis, they will contain four times the normal amount of DNA. With a host of specialized proteins at their disposal,cells must use the right protein at...

DNA Distortion and Damage
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...

The Intrinsic Apoptotic Pathway
6.8K
Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...

Mutations
39.9K
Mutations are changes in the sequence of DNA. These changes can occur spontaneously or they can be induced by exposure to environmental factors. Mutations can be characterized in a number of different ways: whether and how they alter the amino acid sequence of the protein, whether they occur over a small or large area of DNA, and whether they occur in somatic cells or germline cells.
