Insights

MicroRNAs (miRNAs) play a crucial role in colorectal cancer (CRC) development and progression. Understanding these molecules offers potential for novel diagnostic biomarkers and therapeutic strategies for CRC.

Area of Science:

  • Molecular Biology
  • Genetics
  • Oncology

Background:

  • Colorectal cancer (CRC) is a leading cause of cancer death.
  • MicroRNAs (miRNAs) are key regulators of gene expression involved in cancer.
  • miRNAs function as either tumor suppressors or oncogenes in CRC pathogenesis.

Purpose of the Study:

  • To explore the role of microRNAs (miRNAs) in colorectal cancer (CRC).
  • To highlight miRNAs as potential biomarkers and therapeutic targets for CRC.

Main Methods:

  • Literature review on miRNA involvement in CRC.
  • Analysis of miRNA targeting mechanisms (3'-UTR of mRNAs).
  • Examination of miRNA roles in cancer hallmarks (apoptosis, angiogenesis, etc.).

Main Results:

  • miRNAs are differentially expressed and stable in CRC.
  • miRNAs regulate critical biological functions in CRC, including proliferation and migration.
  • Numerous miRNAs show implications in CRC through incompletely understood mechanisms.

Conclusions:

  • miRNAs are integral to CRC pathogenesis and progression.
  • miRNAs hold significant promise as molecular biomarkers for CRC diagnosis and prognosis.
  • Further research into miRNAs may lead to innovative miRNA-based therapeutic strategies for colorectal cancer patients.

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...

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...

siRNA - Small Interfering RNAs

Small interfering RNAs, or siRNAs, are short regulatory RNA molecules that can silence genes post-transcriptionally, as well as the transcriptional level in some cases. siRNAs are important for protecting cells against viral infections and silencing transposable genetic elements.
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the...

lncRNA - Long Non-coding RNAs

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...
