Insights

MicroRNAs regulate gene expression and are linked to cancer development, including colorectal cancer. This review covers their role in cancer pathways, as diagnostic biomarkers, and in therapeutic strategies.

Area of Science:

  • Molecular Biology
  • Epigenetics
  • Oncology

Background:

  • MicroRNAs (miRNAs) are small non-coding RNAs regulating gene expression post-transcriptionally.
  • Recent advances highlight miRNA roles in cell proliferation, differentiation, apoptosis, and immunity.
  • miRNAs are increasingly recognized for their involvement in tumor formation, angiogenesis, metastasis, and chemotherapy resistance, forming a core issue in cancer epigenetics.

Purpose of the Study:

  • To summarize recent findings on microRNAs in colorectal cancer signaling pathways.
  • To introduce potential microRNA biomarkers for colorectal cancer diagnosis and prognosis.
  • To analyze the application of microRNAs in colorectal cancer treatment.

Main Methods:

  • Literature review of recent studies on microRNAs and colorectal cancer.
  • Analysis of signaling pathways implicated in colorectal cancer development.
  • Evaluation of microRNAs as diagnostic and prognostic biomarkers.
  • Assessment of microRNA-based therapeutic strategies for colorectal cancer.

Main Results:

  • MicroRNAs play significant roles in various signaling pathways contributing to colorectal cancer.
  • Specific microRNAs show potential as biomarkers for early diagnosis and predicting patient outcomes.
  • MicroRNAs offer promising avenues for novel colorectal cancer treatment strategies.

Conclusions:

  • MicroRNAs are critical regulators in colorectal cancer pathogenesis.
  • MicroRNAs hold significant potential as biomarkers for improved patient management.
  • Targeting microRNAs presents a promising therapeutic approach for colorectal cancer.

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...

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 (lncRNA)...
