Insights

MicroRNAs (miRNAs) are key players in gastric cancer development, regulating tumor suppressor and oncogenes. Their altered expression is linked to cancer progression, offering potential for new diagnostic and therapeutic strategies.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Gastric cancer is a complex disease with poorly understood development mechanisms.
  • MicroRNAs (miRNAs) are critical regulators involved in gastric carcinogenesis via posttranscriptional control of genes.
  • Numerous studies highlight the role of deregulated miRNAs in various stages of gastric cancer, from early gastritis to metastasis.

Purpose of the Study:

  • To review the fundamental aspects of miRNA biogenesis.
  • To extensively discuss the role of miRNAs in the development of gastric cancer.
  • To explore Helicobacter pylori-related miRNA alterations and their clinical translational potential.

Main Methods:

  • Literature review of scientific publications on miRNAs and gastric cancer.
  • Analysis of miRNA biogenesis pathways.
  • Examination of functional studies on miRNA roles in carcinogenesis.
  • Investigation of clinical studies on miRNA biomarkers and therapeutic applications.

Main Results:

  • MicroRNAs significantly influence gastric carcinogenesis by regulating tumor suppressor genes and oncogenes.
  • Altered miRNA expression patterns are observed throughout the progression of gastric cancer.
  • Helicobacter pylori infection is associated with specific miRNA changes relevant to gastric cancer development.

Conclusions:

  • MicroRNAs are crucial in gastric carcinogenesis, acting as key regulators at the posttranscriptional level.
  • The stability and regulatory roles of miRNAs present significant opportunities for developing biomarkers for gastric cancer screening, diagnosis, prognosis, and therapy.
  • Further research into miRNA alterations, including those related to H. pylori, can lead to improved clinical management of gastric cancer.

MicroRNAs

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...

Gastritis II: Pathophysiology

The pathophysiology of gastritis begins with the colonization of the stomach lining by Helicobacter pylori (H. pylori). This bacterium spreads mainly via the oral-oral route through saliva or shared utensils, and can also be transmitted in overcrowded or unhygienic environments through contaminated water, despite its brief survival outside the body.ColonizationOnce ingested, H. pylori enters the stomach and begins colonization by navigating through the mucus layer lining the stomach wall. It...
mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

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...
