Resumen
Osteopontin influye en las células no tumorales en el microambiente tumoral, afectando la progresión del cáncer y la inmunidad. Comprender estas interacciones ofrece nuevas estrategias terapéuticas para el cáncer.
Área de la Ciencia:
- En el campo de la oncología
- Inmunología
- Biología celular
Sus antecedentes:
- La osteopontina es una proteína de la matriz extracelular crucial involucrada en la progresión del cáncer.
- Las células tumorales interactúan con los componentes del estroma que afectan los resultados del paciente y la respuesta al tratamiento.
Objetivo del estudio:
- Revisar el papel de la osteopontin en las células no tumorales dentro de los cánceres sólidos.
- Para explorar las percepciones fenotípicas y mecanicistas de la influencia de la osteopontina en las células del estroma.
Principales métodos:
- Revisión de la literatura centrada en el papel de la osteopontina en las células no tumorales.
- Análisis de la modulación de las células inmunes innatas y adaptativas por osteopontina.
- Examen de los efectos de la osteopontina en las células estromales estructurales.
Principales resultados:
- Osteopontin influye en varias células inmunes (células NK, neutrófilos, macrófagos, DC, MDSC, células B y células T).
- La osteopontin modula las células estructurales del estroma (fibroblastos, células endoteliales y adipocitos).
- Estas interacciones afectan significativamente la tumorigénesis y la metástasis.
Conclusiones:
- La modulación de las células del estroma por osteopontin juega un papel multiaxial en la progresión del cáncer.
- La comprensión de las vías mediadas por osteopontin/stromal puede conducir a nuevas estrategias diagnósticas y terapéuticas.
- Dirigirse a estas vías puede ofrecer nuevas vías para el tratamiento de la recurrencia del cáncer.

The Tumor Microenvironment
6.8K
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...

Osteoclasts in Bone Remodeling
3.2K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

Interactions Between Signaling Pathways
6.4K
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

mTOR Signaling and Cancer Progression
3.9K
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.

Regulation of Angiogenesis and Blood Supply
2.7K
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

Tumor Progression
6.5K
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...
