Resumen
Este resumen es generado por máquina.Anlotinib demuestra una eficacia superior contra el carcinoma de tiroides anaplásico (ATC) mediante la inducción de la ferroptosis a través del estrés del retículo endoplasmático (ER), ofreciendo una estrategia terapéutica prometedora más allá de la antiangiogénesis.
Área De La Ciencia
- En el campo de la oncología
- Biología molecular
- Terapia contra el cáncer
Sus Antecedentes
- El carcinoma de tiroides anaplásico (ATC) es un cáncer letal.
- La terapia inducida por ferroposis es un tratamiento potencial para la ATC.
- Los efectos de lenvatinib y anlotinib en la ferroptosis en ATC no se conocen bien.
Objetivo Del Estudio
- Investigar la actividad anticancerígena de lenvatinib y anlotinib en el cáncer de tiroides anaplásico (ATC).
- Determinar los mecanismos por los que estos agentes afectan la ferroposis y la angiogénesis en la ATC.
Principales Métodos
- Se utilizaron modelos de tumores subcutáneos in vivo en ratones y ensayos basados en células in vitro.
- Los ensayos incluyeron CCK-8, formación de colonias, transwell, formación de esferas y ensayos de formación de túbulos.
- Los estudios mecánicos incluyeron la medición de especies reactivas de oxígeno (ROS), ferroptosis, marcadores de estrés en el retículo endoplasmático (ER) e inmunohistoquímica.
Principales Resultados
- Tanto el lenvatinib como el anlotinib inhibieron el crecimiento tumoral, mostrando una mayor eficacia.
- Anlotinib demostró efectos antiangiogénicos y antitumorales superiores en comparación con el lenvatinib.
- Anlotinib indujo ferroptosis mediada por ROS a través de la vía de estrés ER, mientras que lenvatinib no lo hizo.
Conclusiones
- Anlotinib es más eficaz que el lenvatinib en el tratamiento de la ATC, independientemente de las propiedades antiangiogénicas.
- La capacidad de Anlotinib para inducir la ferroptosis mediada por el estrés ER destaca su potencial terapéutico para la ATC.
- Dirigirse a la ferroptosis representa una estrategia prometedora para el tratamiento del carcinoma de tiroides anaplásico.

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...
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.
The mTOR pathway or the...
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...
Eukaryotic cells have a special pathway that enables communication between various intracellular membrane-bound compartments and also with the extracellular environment. This pathway is termed as the secretory pathway.
Components of the secretory pathway
About a third of proteins synthesized in the cell are sorted via the secretory route. They shuffle between different compartments in membrane-bound vesicles until they reach their final destination. The main intracellular compartments involved...
Microtubules are dynamic structures that undergo cycles of catastrophe and rescue. The microtubules play a central role in cell division by forming the spindle apparatus for segregating the chromosomes. This makes them ideal targets for regulating dividing cells in tumors and malignant cancer cells. Microtubule stabilizing drugs help stabilize the microtubule formation and promote its polymerization. Paclitaxel was the first microtubule stabilizing agent used as anticancer drug in chemotherapy...
Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:
Receptor tyrosine kinases:
Receptor tyrosine kinases (RTKs) phosphorylate specific tyrosines on the signaling proteins. RTKs include various growth factor receptors,...
