Resumen
La señalización de la fosfoinositida 3-cinasa (PI3K) es crucial en el cáncer. Una nueva investigación explora el PI3K
Área de la Ciencia:
- Oncología y Biología Molecular
Sus antecedentes:
- La elevación de la señalización de la fosfoinositida 3-cinasa (PI3K) es un sello distintivo del cáncer, impulsado por oncogenes y factores de crecimiento.
- Las terapias dirigidas a la vía PI3K están avanzando, con algunas aprobadas para cánceres de sangre y otras en desarrollo.
Objetivo del estudio:
- Proporcionar una perspectiva sobre las funciones de los PI3K de clase I en el metabolismo celular y la función inmune.
- Para discutir cómo estos roles impactan las terapias contra el cáncer dirigidas a PI3K.
- Revisar los avances recientes en el desarrollo de terapias dirigidas a PI3K para el cáncer y otras enfermedades.
Principales métodos:
- Revisión de la literatura existente y de los resultados de las investigaciones sobre las funciones de PI3K.
- Análisis de la interacción entre PI3K, el metabolismo, la inmunidad y el cáncer.
- Discusión de las estrategias terapéuticas actuales y emergentes dirigidas a PI3K.
Principales resultados:
- Las subunidades PI3K juegan un papel importante en el metabolismo celular normal y las funciones del sistema inmunológico.
- Estas funciones no oncogénicas pueden influir en la eficacia y toxicidad de las terapias contra el cáncer dirigidas a PI3K.
- Diversos inhibidores de PI3K se encuentran en diversas etapas de desarrollo clínico para múltiples enfermedades.
Conclusiones:
- Comprender las funciones más amplias de PI3K en el metabolismo y la inmunidad es fundamental para optimizar el tratamiento del cáncer.
- La investigación adicional sobre la regulación de PI3K y la inhibición dirigida es prometedora para mejorar el tratamiento del cáncer y el manejo de las toxicidades relacionadas.

01:22PI3K/mTOR/AKT Signaling Pathway
5.8K
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...

03:03mTOR Signaling and Cancer Progression
4.9K
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.

7.4K
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...

01:20The JAK-STAT Signaling Pathway
13.3K
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...

01:11IP3/DAG Signaling Pathway
15.2K
Membrane lipids such as phosphatidylinositol (PI) are precursors for several membrane-bound and soluble second messengers. Specific kinases phosphorylate PI and produce phosphorylated inositol phospholipids. One such inositol phospholipids are the phosphatidylinositol-4,5 bisphosphate [PI(4,5)P2], present in the inner half of the lipid bilayer. Upon ligand binding, GPCR stimulates Gq proteins to turn on phospholipase Cꞵ. Activated phospholipase Cꞵ cleaves PI(4,5)P2 and...

03:14Notch Signaling Pathway
6.7K
The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not...
