Insights

MicroRNAs (miRNAs) are key regulators in human cancers, acting as oncogenes or tumor suppressors. This review covers their roles in cancer development and therapeutic potential in preclinical studies.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • MicroRNAs (miRNAs) are small non-coding RNAs that regulate gene expression.
  • Aberrant miRNA expression is a hallmark of human cancers.
  • miRNAs can function as either oncogenes or tumor suppressors in tumorigenesis.

Purpose of the Study:

  • To provide a comprehensive overview of the current research on miRNA roles in cancer development.
  • To discuss the progress and limitations of miRNA-based therapeutics in preclinical settings.

Main Methods:

  • Literature review of peer-reviewed studies on miRNAs and cancer.
  • Analysis of current preclinical therapeutic strategies involving miRNAs.

Main Results:

  • miRNAs are significantly deregulated in various human cancers.
  • Evidence supports their critical roles in multiple stages of tumorigenesis.
  • Preclinical studies show promise but also highlight challenges for miRNA-based therapies.

Conclusions:

  • miRNAs are crucial players in cancer biology.
  • Targeting miRNAs holds therapeutic potential, but further research is needed to overcome existing limitations for clinical application.

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...

Targeted Cancer Therapies02:57

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 specific...

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)...
Experimental RNAi02:15

Experimental RNAi

RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...
