Insights

Dietary factors can alter microRNA (miRNA) expression, influencing cancer development. Understanding this link may lead to new strategies for cancer prevention through diet.

Area of Science:

  • Molecular Biology
  • Genetics
  • Oncology

Background:

  • MicroRNAs (miRNAs) are small noncoding RNAs regulating gene expression.
  • Aberrant miRNA expression is linked to human diseases, particularly cancer.
  • miRNAs play critical roles in cancer hallmarks like proliferation, metastasis, and angiogenesis.

Purpose of the Study:

  • To review the role of dietary factors in modulating miRNA expression.
  • To explore the potential of dietary modulation of miRNAs for cancer prevention.

Main Methods:

  • Literature review of studies on diet, miRNA expression, and cancer.
  • Analysis of mechanisms by which dietary components affect miRNA and mRNA targets.

Main Results:

  • Dietary components can influence miRNA expression and function.
  • Modulation of miRNA by diet impacts cancer-related pathways such as apoptosis, cell cycle, and metastasis.
  • Circulating miRNAs affected by diet may act both locally and at distant sites.

Conclusions:

  • Dietary modulation of miRNA expression is a promising avenue for cancer prevention.
  • Further research into diet-miRNA interactions can inform public health strategies against cancer.

MicroRNAs01:22

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...

Cancer Prevention02:59

Cancer Prevention

Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

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...
