The Tumor Microenvironment02:17

The Tumor Microenvironment

7.2K
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...

Cancer Prevention

7.2K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Mismatch Repair

5.7K
Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.
The Mutator Protein Family Plays a Key Role in DNA Mismatch Repair
The human genome has more than 3 billion base pairs of DNA per cell. Prior to cell division, that vast amount of genetic...

Mouse Models of Cancer Study

6.1K
Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...

Psychoneuroimmunology: Diabetes and Cancer01:19

Psychoneuroimmunology: Diabetes and Cancer

128
Chronic stress has been linked to both the onset and progression of serious health conditions, including Type 2 diabetes and cancer. Type 2 diabetes, a widespread chronic illness, is closely associated with obesity and insulin resistance, both of which often worsen under stress. Studies indicate that men experiencing high levels of chronic stress face a 45% higher risk of developing diabetes compared to those with minimal stress. Stress triggers physiological responses that elevate blood...

Resumen

Los microbios pueden desempeñar un papel en el cáncer, influyendo en la inmunidad y el tratamiento. Esta revisión distingue entre la causalidad directa y la complicidad, explorando el eje inmuno-oncología-microbioma para la investigación futura del cáncer.

Área de la Ciencia:

  • En el campo de la oncología
  • Microbiología
  • Inmunología

Sus antecedentes:

  • El papel de los microbios en el cáncer ha sido objeto de debate durante siglos.
  • Investigaciones recientes sugieren que los microbios están involucrados en la inmunoterapia del cáncer y el tratamiento de las metástasis.
  • Sin embargo, se sabe que pocos microbios causan directamente el cáncer.

Objetivo del estudio:

  • Evaluar críticamente la evidencia de la participación microbiana en el cáncer.
  • Diferenciar entre los roles causales y cómplices de los microbios en la carcinogénesis.
  • Explorar el eje inmunoncología-microbioma y las direcciones de investigación futuras.

Principales métodos:

  • Revisión de la literatura y análisis crítico de los estudios existentes.
  • Delimitación de las funciones microbianas (causal frente a cómplice) en el cáncer.
  • Examen de la influencia de los microbios en el sistema inmunológico del huésped.

Principales resultados:

  • Los microbios pueden ser causales o cómplices en el desarrollo del cáncer.
  • El sistema inmunológico del huésped es un mediador clave en el eje inmuno-oncología-microbioma.
  • Se discuten los microbios intratumorales y las estrategias de manipulación del microbioma.

Conclusiones:

  • Comprender la compleja interacción entre los microbios y el cáncer es crucial.
  • La investigación futura debe centrarse en el eje inmuno-oncología-microbioma.
  • La manipulación del microbioma tiene potencial para el tratamiento del cáncer.
