Resumen
La vía de señalización Wnt es crucial en la salud y la enfermedad, especialmente en la fibrosis tisular. La focalización de las proteínas relacionadas con Frizzled secretadas (SFRP) ofrece una estrategia terapéutica prometedora para la intervención antifibrótica.
Área de la Ciencia:
- Biología Molecular
- Biología Celular
- Patología
Sus antecedentes:
- La vía de señalización Wnt regula procesos fisiológicos y patológicos críticos.
- La desregulación de la señalización Wnt contribuye a la disfunción celular y a diversas enfermedades, incluida la fibrosis tisular.
- La fibrosis implica la activación de miofibroblastos y el depósito excesivo de matriz extracelular, siendo la señalización Wnt un impulsor clave.
Objetivo del estudio:
- Proporcionar una revisión integral de los componentes de la vía Wnt, su regulación y estrategias terapéuticas.
- Enfatizar el papel de la señalización Wnt en la fibrosis y otras enfermedades.
- Destacar las proteínas relacionadas con Frizzled secretadas (SFRP) como posibles dianas antifibróticas.
Principales métodos:
- Revisión sistemática de la literatura sobre la señalización Wnt.
- Análisis del papel de la vía Wnt en el desarrollo y la enfermedad, centrándose en la fibrosis.
- Examen de las SFRP como moduladores de la señalización Wnt.
- Revisión de estudios preclínicos y clínicos sobre terapéuticas dirigidas a Wnt.
Principales resultados:
- La señalización Wnt es central en la progresión fibrótica en múltiples órganos.
- Las SFRP exhiben efectos bifásicos y dependientes del contexto, lo que las hace particularmente relevantes en la fibrosis.
- El desarrollo de compuestos de molécula pequeña dirigidos a componentes de Wnt muestra progreso y desafíos.
Conclusiones:
- Las estrategias terapéuticas eficaces dirigidas a la señalización Wnt en la fibrosis son limitadas.
- Las SFRP representan dianas prometedoras para intervenciones antifibróticas.
- La investigación adicional sobre la modulación de la vía Wnt es vital para el tratamiento de enfermedades fibróticas.

02:54Canonical Wnt Signaling Pathway
10.4K
The gene encoding the main signaling molecules of the Wnt signaling pathways (the Wnt proteins) was discovered almost four decades ago by Nüsslein-Volhard and Wieschaus. They identified and originally named the gene "wingless" (wg) after a phenotype discovered during their landmark genetic screen in Drosophila for body pattern defects. At around the same time, another researcher named Harold Varmus found that a murine tumor virus activates the mammalian wg homolog, Int-1, which...

01:41Non-Canonical Wnt Signaling Pathways
8.3K
Wnt is a zygotic effect gene that is expressed during very early embryonic development. It regulates various processes in animals starting from early development through the adult stage, such as organogenesis in the embryo and maintenance of neuronal and blood stem cells. Wnt proteins can induce a wide variety of intracellular pathways depending upon the specific abilities of different Wnt ligands to form a complex with shared and cognate receptors in the presence of different co-receptors. The...

03:14Notch Signaling Pathway
6.4K
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...

01:19Interactions Between Signaling Pathways
7.2K
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...

01:16TGF - β Signaling Pathway
10.5K
The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors...

02:33Hedgehog Signaling Pathway
9.8K
The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...
