Spheroid Assay to Measure TGF-β-induced Invasion
Published on: November 16, 2011
Resumen
Las células cancerosas logran la autonomía del factor de crecimiento a través de la secreción autocrina, impulsada por oncogenes. Dirigirse a estas vías autocrinas, incluidos los factores de crecimiento negativos, ofrece estrategias terapéuticas potenciales para el cáncer.
Área de la Ciencia:
- Oncología Oncología.
- Biología Molecular Biología Molecular
- La señalización celular de las células.
Sus antecedentes:
- Las células cancerosas exhiben secreción autocrina, produciendo y respondiendo a sus propios factores de crecimiento.
- Los oncogenes juegan un papel crucial en la concesión de la autonomía del factor de crecimiento de las células cancerosas.
- Esta autonomía se logra mediante la codificación de oncogenes para factores de crecimiento / receptores o amplificando las señales mitogénicas.
Objetivo del estudio:
- Explorar el papel central de la secreción del factor de crecimiento autocrino en la vinculación de la investigación oncogénica y del factor de crecimiento.
- Investigar cómo los oncogenes confieren autonomía al factor de crecimiento en las células cancerosas.
- Examinar el potencial terapéutico de dirigirse a las vías del factor de crecimiento autocrino.
Principales métodos:
- Revisión de la literatura existente sobre oncogenes, factores de crecimiento y señalización de células cancerosas.
- Análisis de los mecanismos por los cuales los oncogenes influyen en los circuitos autocrinos.
- Examen de los datos experimentales sobre la eficacia de los antagonistas del factor de crecimiento autocrino.
Principales resultados:
- La secreción autocrina es un mecanismo clave para la proliferación y supervivencia de las células cancerosas.
- Los oncogenes promueven directa o indirectamente los circuitos de señalización autocrina.
- La inhibición de factores de crecimiento autocrinos positivos demuestra efectos anticancerígenos en modelos animales.
Conclusiones:
- Los circuitos del factor de crecimiento autocrino son fundamentales para el desarrollo y la progresión del cáncer.
- Dirigirse a las vías autocrinas, incluidos los factores autocrinos negativos, presenta una vía prometedora para la terapia del cáncer.

Autocrine Signaling
Autocrine signaling is one of the many signaling mechanisms that function inside multicellular organisms to carry out intercellular communication. In this type of signaling mechanism, the same cell that secretes an extracellular signaling molecule also expresses the receptors to bind and respond to that signaling molecule.

Cancer
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
Mitogens and the Cell Cycle
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
mTOR Signaling and Cancer Progression
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.
