- Metástasis del cáncer Metástasis del cáncer
- Biología celular Biología celular.
Sus antecedentes:
- Las células cancerosas metastásicas requieren adaptaciones específicas de órganos para una colonización exitosa.
- El microambiente tumoral, incluido el estroma primario, juega un papel crítico en la progresión del cáncer.
Objetivo del estudio:
- Investigar cómo el estroma del tumor primario influye en la adquisición de rasgos específicos de la metástasis ósea en las células de cáncer de mama.
Principales métodos:
- Análisis de los perfiles de expresión génica en las células de cáncer de mama.
- Modelos de cocultivo in vitro con componentes del estroma tumoral primario.
- Modelos de metástasis in vivo. también conocidos como modelos de metástasis.
Principales resultados:
- Se descubrió que las señales del estroma tumoral primario influyen significativamente en la expresión de los genes asociados con las metástasis óseas.
- Las células de cáncer de mama expuestas a señales de estroma primarias demostraron una mayor capacidad para colonizar el tejido óseo.
Conclusiones:
- El estroma tumoral primario es un regulador clave del potencial metastásico, específicamente para la colonización ósea en el cáncer de mama.
- Dirigirse a las interacciones estroma-estroma podría ofrecer nuevas estrategias terapéuticas para prevenir la metástasis ósea.

Metastasis
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...

Tumor Progression
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

The Tumor Microenvironment
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...
