Insights

MicroRNAs (miRNAs) regulate autophagy, a cellular process involved in cancer progression and metastasis. Targeting miRNAs offers a potential therapeutic strategy for colorectal cancer by modulating this pathway.

Area of Science:

  • Molecular Biology
  • Oncology
  • Biochemistry

Background:

  • Autophagy is a conserved cellular degradation pathway crucial for cell survival.
  • Dysfunctional autophagy is implicated in cancer progression, adaptation, and metastasis, making it a therapeutic target.
  • MicroRNAs (miRNAs) are non-coding RNAs that regulate gene expression and play a dual role in colorectal cancer.

Purpose of the Study:

  • To elucidate the molecular mechanisms by which miRNAs regulate the dual role of autophagy in colorectal cancer.
  • To highlight the role of long noncoding RNAs (lncRNAs) in modulating miRNA expression and autophagy in colorectal cancer.

Main Methods:

  • Literature review and molecular pathway analysis.
  • Examination of miRNA-mRNA interactions in the context of autophagy.
  • Analysis of lncRNA-miRNA interactions influencing autophagy.

Main Results:

  • miRNAs exhibit context-dependent roles as tumor suppressors or promoters in colorectal cancer by regulating autophagy.
  • Dysregulation of autophagy by miRNAs contributes to cancer progression and metastasis.
  • lncRNAs can modulate miRNA expression, thereby influencing autophagy in colorectal cancer.

Conclusions:

  • miRNAs are key regulators of autophagy with a significant impact on colorectal cancer.
  • Targeting the miRNA-autophagy axis presents a promising therapeutic avenue for colorectal cancer treatment.
  • Understanding lncRNA-mediated regulation of miRNAs in autophagy is critical for developing novel cancer therapies.

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.

Autophagy01:27

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,...

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...

Delivery Pathways to the Lysosome

Eukaryotic cells use different mechanisms to eliminate toxic waste obsolete and worn-out substances. Lysosomes play a pivotal role in this, and hence, these substances are carried to the lysosome from other parts of the cell and extracellular space through different pathways. The most elaborately studied pathways to the lysosome are the endocytic pathways.
Endocytosis
In endocytosis, the cell membrane takes up macromolecules and particles from the surrounding medium. Clathrin-mediated...

Destabilization of Microtubules01:45

Destabilization of Microtubules

The destabilization of microtubules can occur during different stages of the microtubule lifecycle, such as nucleation or elongation. It can take place at either end of the microtubule or in the microtubule lattices as a whole. The lifespan of individual microtubules within a cell varies according to the cell type and stage of the cell cycle. During interphase, the lifespan of the microtubule is about 30 minutes, while during cell division, it is about 15 minutes. In axonal microtubules of...
