Insights

MicroRNAs (miRNAs) are crucial regulators in colorectal cancer (CRC) development and chemoresistance. This review clarifies their complex roles, identifying key miRNAs for potential diagnostic and therapeutic strategies in CRC.

Area of Science:

  • Molecular biology
  • Genetics
  • Oncology

Background:

  • MicroRNAs (miRNAs) regulate gene expression; their dysregulation is implicated in diseases, including cancer.
  • Colorectal cancer (CRC) involves genetic and epigenetic changes, with miRNAs playing a significant pathogenetic role.
  • Current understanding of specific miRNA functions in CRC tumorigenesis, progression, and chemoresistance lacks consensus.

Purpose of the Study:

  • To elucidate the multifaceted roles of miRNAs in colorectal cancer.
  • To examine miRNA involvement in major oncogenic pathways relevant to CRC.
  • To identify key miRNAs as potential diagnostic biomarkers and therapeutic targets for CRC.

Main Methods:

  • Comprehensive literature review of studies on miRNAs in colorectal cancer.
  • Analysis of miRNA involvement in CRC pathogenetic mechanisms.
  • Evaluation of current evidence for miRNA-based diagnostics and therapeutics in CRC.

Main Results:

  • miRNAs are key players in CRC initiation, progression, and chemoresistance.
  • Specific miRNAs are frequently dysregulated in CRC, impacting oncogenic pathways.
  • Significant potential exists for miRNAs as biomarkers and therapeutic targets in CRC.

Conclusions:

  • A deeper understanding of miRNA functions is essential for advancing CRC management.
  • Clarifying miRNA roles can lead to improved CRC monitoring and novel therapeutic strategies.
  • miRNA-guided approaches offer promise for future colorectal cancer treatment and prevention.

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 mTOR pathway or the...

Drugs that Stabilize Microtubules

Microtubules are dynamic structures that undergo cycles of catastrophe and rescue. The microtubules play a central role in cell division by forming the spindle apparatus for segregating the chromosomes. This makes them ideal targets for regulating dividing cells in tumors and malignant cancer cells. Microtubule stabilizing drugs help stabilize the microtubule formation and promote its polymerization. Paclitaxel was the first microtubule stabilizing agent used as anticancer drug in chemotherapy...
