Resumen
Las células tumorales circulantes (CTC) propagan el cáncer. Un nuevo estudio muestra que estas células también pueden reingresar a los tumores primarios, impulsando un mayor crecimiento del cáncer.
Área de la Ciencia:
- Oncología Oncología.
- Biología del cáncer Biología del cáncer.
- Investigación de las Metástasis Investigación de las Metástasis.
Sus antecedentes:
- Las células tumorales circulantes (CTC) son conductores establecidos de la enfermedad metastásica.
- El papel de los CTC en la progresión del tumor primario sigue siendo menos entendido.
Objetivo del estudio:
- Investigar el papel potencial de los CTC en la progresión y reinfiltración de tumores primarios.
Principales métodos:
- Utilizó técnicas avanzadas de imagen y seguimiento genético en modelos preclínicos.
- Analizó el microambiente tumoral y las interacciones celulares.
Principales resultados:
- Se demostró que los CTC pueden re-infiltrarse con éxito en los tumores primarios después de entrar en la circulación.
- Se observó que la reinfiltración de CTCs contribuye al aumento del crecimiento y la progresión del tumor.
Conclusiones:
- Las células tumorales circulantes poseen un doble papel en la diseminación del cáncer: siembran metástasis distantes y promueven el crecimiento del tumor primario.
- Dirigirse a las CTC puede ofrecer una nueva estrategia terapéutica tanto para la enfermedad metastásica como para la primaria.

01:27Tumor Immunotherapy
2.0K
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

02:40Cancer Stem Cells and Tumor Maintenance
6.0K
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.

02:07Tumor Progression
7.5K
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...

02:17The Tumor Microenvironment
7.9K
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...

02:33Seed Structure and Early Development of the Sporophyte
31.3K
Seed structures are composed of a protective seed coat surrounding a plant embryo, and a food store for the developing embryo. The embryo contains the precursor tissues for leaves, stem, and roots. The endosperm and cotyledons—seed leaves—act as the food reserves for the growing embryo.

01:12Loss of Tumor Suppressor Gene Functions
6.1K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
