Insights

MicroRNAs regulate gene expression and are crucial in cancer development and progression. Targeting microRNAs offers new therapeutic strategies and diagnostic tools for personalized cancer medicine.

Area of Science:

  • Molecular Biology
  • Genetics
  • Oncology

Background:

  • MicroRNAs (miRNAs) are small non-coding RNAs that regulate gene expression.
  • Dysregulation of miRNAs is implicated in the initiation, progression, metastasis, and therapeutic resistance of various human cancers.
  • miRNAs play a significant role in cellular processes, making them key players in tumorigenesis.

Purpose of the Study:

  • To review the multifaceted roles of microRNAs in cancer biology.
  • To highlight microRNAs as potential therapeutic targets for novel anticancer strategies.
  • To discuss the application of microRNA profiles in cancer diagnosis, prognosis, and theranosis.

Main Methods:

  • Literature review of studies on microRNA biology and cancer.
  • Analysis of microRNA involvement in tumorigenesis stages.
  • Examination of microRNA-based diagnostic and therapeutic approaches.

Main Results:

  • MicroRNAs are critical regulators of gene expression and cellular functions.
  • Aberrant miRNA expression is a hallmark of many human cancers.
  • miRNA profiles serve as valuable tumor-specific signatures for cancer detection and management.

Conclusions:

  • MicroRNAs are pivotal molecules in cancer development and progression.
  • Restoring miRNA expression or function presents a promising avenue for cancer therapy.
  • MicroRNAs are integral to personalized medicine for cancer diagnosis, prognosis, and treatment monitoring.

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...

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

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...
