Resumen
Este resumen es generado por máquina.El circRNA-5 del virus de la hepatitis B (VHB) impulsa el cáncer de hígado (HCC) al promover el crecimiento y la propagación celular. Este circRNA del VHB se dirige a miR-9-3p, activando la vía YAP/TAZ y la vía Hippo, ofreciendo nuevas dianas terapéuticas para el CHC relacionado con el VHB.
Área De La Ciencia
- Hepatología y Oncología Viral
- Biología Molecular y Carcinogénesis
Sus Antecedentes
- La infección crónica por el virus de la hepatitis B (VHB) sigue siendo un problema de salud mundial importante, que conduce a enfermedades del hígado y al carcinoma hepatocelular (HCC).
- A pesar de la vacunación, millones están en riesgo de complicaciones hepáticas relacionadas con el VHB, y los mecanismos moleculares que impulsan el desarrollo de HCC no se comprenden completamente.
Objetivo Del Estudio
- Investigar el papel del ARN circular codificado por el VHB (ARNc) en la patogénesis del CHC mediado por el VHB.
- Elucidar el mecanismo molecular por el cual el VHB promueve la progresión del CHC.
Principales Métodos
- Se realizaron experimentos in vitro e in vivo para evaluar la función del HBV-circRNA-5.
- Los estudios de mecanismo incluyeron el análisis de la interacción entre HBV-circRNA-5, miR-9-3p y la vía de señalización YAP/TAZ.
Principales Resultados
- La sobreexpresión de HBV-circRNA-5 promovió significativamente la proliferación y la metástasis de las células de HCC in vitro.
- El HBV-circRNA-5 aumentó el crecimiento del tumor de HCC in vivo.
- Mecanísticamente, se encontró que el HBV-circRNA-5 se une a miR-9-3p, lo que lleva a la regulación al alza de YAP/TAZ y a la posterior proliferación de HCC a través de la red Hippo.
Conclusiones
- El HBV-circRNA-5 es un factor crítico en el desarrollo y la progresión del CHC asociado al HBV.
- La vía HBV-circRNA-5/miR-9-3p/Hippo representa un nuevo mecanismo subyacente a la carcinogénesis inducida por el HBV.
- Este estudio identifica posibles objetivos terapéuticos para el tratamiento del CHC relacionado con el VHB.

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...
Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...
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...
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...
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.
The mTOR pathway or the...
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...
