Insights

MicroRNAs (miRNAs) play a crucial role in gastric cancer (GC) development and progression. This review explores recent findings on miRNA mechanisms for potential clinical applications in diagnosing and treating this deadly disease.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Gastric cancer (GC) is a significant global health challenge, ranking as the sixth most common and third deadliest cancer worldwide.
  • MicroRNAs (miRNAs), small non-coding RNA molecules, regulate gene expression post-transcriptionally and are increasingly implicated in various diseases.

Purpose of the Study:

  • To review and summarize recent (past three years) research on microRNAs (miRNAs) mechanistically linked to gastric cancer (GC).
  • To explore the potential clinical applications of these miRNAs in GC diagnosis, treatment, and prognosis.

Main Methods:

  • Literature review focusing on studies published within the last three years.
  • Analysis of confirmed mechanisms of action for miRNAs involved in gastric cancer.
  • Synthesis of findings to predict clinical utility.

Main Results:

  • Numerous microRNAs (miRNAs) have been identified with confirmed roles in the oncogenesis, development, diagnosis, treatment, and prognosis of gastric cancer (GC).
  • Despite extensive research, few miRNAs have translated into clinical practice for GC management.

Conclusions:

  • Understanding the specific mechanisms of action of recently identified gastric cancer-associated miRNAs is crucial.
  • These miRNAs hold promise for novel clinical applications, offering new strategies to overcome 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...

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 Tumor Microenvironment02:17

The Tumor Microenvironment

Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
