Insights

Autophagy, a cellular self-digestion process, is crucial in cancer. MicroRNAs (miRNAs) interact with autophagy, offering potential as anti-cancer targets and therapeutic delivery strategies.

Area of Science:

  • Molecular Biology
  • Cell Biology
  • Oncology

Background:

  • Autophagy is a fundamental cellular process involving lysosomal degradation of cellular components.
  • Dysregulation of autophagy is implicated in cancer initiation, progression, and stress responses.
  • Autophagy is regulated by specific genes and pathways, and is influenced by microRNAs (miRNAs).

Purpose of the Study:

  • To review the intricate relationship between microRNAs and autophagy.
  • To explore the potential of targeting miRNA-autophagy networks in pre-clinical cancer models.
  • To summarize and discuss miRNA delivery strategies for anti-cancer therapies.

Main Methods:

  • Literature review of studies on miRNA-autophagy interactions.
  • Analysis of pre-clinical cancer models utilizing miRNA-mediated autophagy.
  • Synthesis of information on miRNA delivery systems for cancer therapy.

Main Results:

  • MicroRNAs significantly regulate autophagy, influencing its role in cancer.
  • Targeting the interplay between miRNAs and autophagy shows promise in pre-clinical cancer studies.
  • Various miRNA delivery strategies are being developed for anti-cancer applications.

Conclusions:

  • The interaction between miRNAs and autophagy presents a novel therapeutic avenue for cancer.
  • Further research into miRNA-autophagy networks and delivery systems is warranted for effective anti-cancer strategies.

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...

Autophagy

Autophagy is a self-digesting process by which a cell protects itself from threats both within and outside the cell, ranging from abnormal proteins to invading bacteria. In this process, obsolete components of the cell and invading microbes are degraded by hydrolytic enzymes active in an acidic environment of the lysosomal lumen.
An autophagic pathway consists of a series of signaling events activated in response to diverse stress and physiological conditions such as food deprivation,...

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...
