|March 10, 2009
Resumen
La reducción de la proteína sensora de oxígeno endotelial interrumpe los circuitos de retroalimentación tumoral, disminuyendo la metástasis. Este hallazgo ofrece nuevos objetivos terapéuticos para el tratamiento del cáncer.
Área de la Ciencia:
- Oncología Oncología.
- Biología Vascular Biología Vascular
- Fisiología Celular Fisiología celular
Sus antecedentes:
- Los vasos sanguíneos tumorales son ineficientes, causando hipoxia y promoviendo factores proangiogénicos en un ciclo.
- Este ciclo de retroalimentación hipoxia-angiogénesis del tumor apoya el crecimiento y la propagación del tumor.
Objetivo del estudio:
- Para investigar el papel de la detección de oxígeno endotelial en la progresión tumoral.
- Para determinar si la modulación de esta vía puede interrumpir el bucle de retroalimentación de la hipoxia.
- Para evaluar el impacto en la metástasis tumoral.
Principales métodos:
- El estudio se centró en una proteína específica involucrada en la detección de oxígeno endotelial.
- Los investigadores manipularon los niveles de esta proteína en modelos preclínicos.
- Se analizaron los cambios en la forma de las células endoteliales y la metástasis tumoral.
Principales resultados:
- Reducir la proteína alteró la morfología de las células endoteliales.
- Estos cambios celulares interrumpieron efectivamente el bucle de retroalimentación impulsado por la hipoxia.
- Se observó una reducción significativa en la metástasis tumoral.
Conclusiones:
- Dirigirse a la detección de oxígeno endotelial presenta una estrategia prometedora.
- La modulación de esta vía puede inhibir la metástasis tumoral.
- Esta investigación abre nuevas vías para las terapias contra el cáncer.

The Tumor Microenvironment
6.3K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Metastasis
5.4K
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Cancer Cell Migration through Invadopodia
2.5K
Invadosome is a broad category of cell surface structures with proteolytic activity that degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...

Overview of the Vascular System
2.7K
The vascular system comprises an extensive network of arteries, capillaries, and veins. The vascular system can be broadly divided into the blood and lymphatic systems. Typically, blood vessels can be categorized into three histological regions: tunica intima, tunica media, and tunica adventitia. The tunica intima consists of a single layer of endothelial cells attached to the basal lamina. Underlying the basal lamina is a connective tissue layer and an elastic lamina that gives stability and...

Regulation of Angiogenesis and Blood Supply
2.9K
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

Selectins
3.6K
Cell adhesion is an essential aspect of multicellularity. While stable cell interactions usually occur between cells of the same type, transient cell interactions occur between cells of different tissue types, such as between neutrophils and endothelial cells. Selectins are one class of cell adhesion molecules (CAMs) that bind carbohydrate ligands to form transient cell adhesion. They are rod-like proteins with a long extracellular part of variable length ending with the lectin domain,...
