Resumen
La periostina (POSTN) juega un doble papel en la progresión del cáncer dentro del microambiente tumoral (TME). Los niveles bajos de POSTN pueden inhibir el crecimiento del cáncer al prevenir la transición epitelial a mesenquimal (EMT), mientras que los niveles altos promueven la metástasis.
Área de la Ciencia:
- En el campo de la oncología
- Biología del cáncer
- Biología molecular
Sus antecedentes:
- El microambiente tumoral (TME) es crucial en la progresión del cáncer, influyendo en la respuesta inmune, la metástasis y la resistencia al tratamiento.
- Las proteínas matricelulares, como la periostina (POSTN), son reguladores clave dentro de la EMT.
- Comprender el papel de POSTN es vital para el desarrollo de nuevas terapias contra el cáncer.
Objetivo del estudio:
- Revisar el papel multifacético de la periostina (POSTN) en el cáncer.
- Explorar el POSTN como biomarcador para el crecimiento del cáncer y la resistencia al tratamiento.
- Para discutir el potencial de POSTN como un factor de pronóstico y terapéutico.
Principales métodos:
- Revisión de la literatura centrada en la función de la periostina en el cáncer.
- Análisis de estudios que investigan el impacto de POSTN en la biología tumoral.
- Examen de la interacción de POSTN con las vías de señalización como la integrina.
Principales resultados:
- La periostina (POSTN) exhibe una doble función dependiente de la concentración en la progresión del tumor.
- Los niveles bajos de POSTN pueden inhibir el cáncer al prevenir la transición epitelial a mesenquimal (EMT).
- Los niveles altos de POSTN pueden promover la migración y la metástasis a través de la señalización de la integrina.
Conclusiones:
- La periostina (POSTN) es un factor significativo en la progresión del cáncer y la resistencia al tratamiento.
- La orientación de POSTN presenta una estrategia terapéutica potencial, teniendo en cuenta sus funciones complejas.
- Se requiere más investigación sobre el doble papel de POSTN para un tratamiento eficaz del cáncer.

02:17The 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...

03:03mTOR 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.

02:38Mitogens and the Cell Cycle
6.6K
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...

02:07Tumor 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...

01:22PI3K/mTOR/AKT Signaling Pathway
3.9K
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a...

02:23Abnormal Proliferation
4.6K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...
