Resumen
El microbioma humano puede promover el desarrollo del cáncer al debilitar el sistema inmunológico y ayudar a la propagación de las células cancerosas. Esta investigación pone de relieve el papel complejo de las bacterias intestinales en la oncología.
Área de la Ciencia:
- En el campo de la oncología
- Microbiología
- Inmunología
Sus antecedentes:
- El microbioma humano juega un papel fundamental en la salud y la enfermedad.
- La evidencia emergente sugiere que las comunidades microbianas pueden influir en el inicio y la progresión del cáncer.
Objetivo del estudio:
- Investigar el papel potencial del microbioma en la promoción del cáncer.
- Explorar los mecanismos por los que el microbioma puede influir en la respuesta inmune y la metástasis.
Principales métodos:
- Análisis de las comunidades microbianas en pacientes con cáncer.
- Experimentos in vivo e in vitro para evaluar la modulación inmune por los microbios.
- Estudios sobre la siembra microbiana de los sitios metastásicos.
Principales resultados:
- Las composiciones microbianas específicas se asociaron con un mayor crecimiento tumoral.
- Se encontró que el microbioma suprime las respuestas inmunes antitumorales.
- Se observó evidencia de presencia microbiana en las lesiones metastásicas.
Conclusiones:
- El microbioma puede actuar como promotor de la progresión del cáncer.
- La supresión inmune mediada por el microbioma y la siembra metastásica son mecanismos clave.
- Dirigirse al microbioma puede ofrecer nuevas estrategias terapéuticas para el cáncer.

02:17The Tumor Microenvironment
6.7K
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...

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.

01:27Tumor Immunotherapy
631
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.

02:30Metastasis
5.6K
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...

02:07Tumor Progression
6.4K
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...

02:11The Roles of Bacteria and Fungi in Plant Nutrition
38.0K
Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.
