Resumen

Este resumen es generado por máquina.

El ARN largo no codificante SNHG5 inhibe la progresión del cáncer gástrico mediante la regulación de miR-92a-3p y BTG2. Este estudio revela SNHG5 como un objetivo terapéutico potencial para el tratamiento del cáncer gástrico.

Área De La Ciencia

  • En el campo de la oncología
  • Biología molecular
  • Regulación genética

Sus Antecedentes

  • El cáncer gástrico (GC) es un problema de salud mundial significativo con altas tasas de mortalidad.
  • Comprender los mecanismos moleculares subyacentes a la progresión de la GC es crucial para desarrollar tratamientos efectivos.

Objetivo Del Estudio

  • Investigar el papel funcional del ARN largo no codificante SNHG5 (pequeño ARN nucleolar del gen huésped 5) en el cáncer gástrico.
  • Para aclarar la relación reguladora entre SNHG5, miR-92a-3p y BTG2 en la progresión GC.

Principales Métodos

  • PCR de transcripción inversa cuantitativa y Western blot para evaluar la expresión de SNHG5, miR-92a-3p y BTG2 en los tejidos GC.
  • Pruebas de doble luciferasa para confirmar las interacciones entre SNHG5, miR-92a-3p y BTG2.
  • Experimentos in vitro (líneas celulares) e in vivo (modelos de ratón xenotransplantado) para evaluar el impacto de SNHG5 y miR-92a-3p en la proliferación, migración y crecimiento de las células GC.

Principales Resultados

  • SNHG5 y BTG2 fueron regulados a la baja, mientras que miR-92a-3p fue regulado al alza en los tejidos GC.
  • La sobreexpresión de SNHG5 o la eliminación de miR-92a-3p suprimieron la proliferación y migración de las células GC, aumentaron la expresión de BTG2 e inhibieron la vía PI3K/ AKT.
  • Los estudios in vivo mostraron una reducción del crecimiento tumoral con sobreexpresión de SNHG5 o inhibición de miR-92a-3p.

Conclusiones

  • El LncRNA SNHG5 actúa como supresor tumoral en el cáncer gástrico.
  • SNHG5 inhibe el crecimiento y la migración de las células GC mediante la modulación de la vía PI3K/AKT a través del eje miR-92a-3p/BTG2.
  • SNHG5 representa un objetivo terapéutico potencial para el cáncer gástrico.

lncRNA - Long Non-coding RNAs 02:39

8.9K

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

Abnormal Proliferation 02:23

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...

MicroRNAs 01:22

3.1K

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

mTOR Signaling and Cancer Progression 03:03

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.
The mTOR pathway or the...

The Retinoblastoma Gene 01:20

4.2K

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Mitogens and the Cell Cycle 02:38

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...
