Insights

MicroRNAs (miRNAs) show promise in predicting cancer treatment response and resistance. Understanding miRNA roles can improve targeted cancer therapies and overcome drug resistance.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Targeted cancer therapies, based on oncogene addiction, have revolutionized treatment.
  • Therapeutic efficacy is often limited by the development of drug resistance.
  • While protein alterations are known resistance mechanisms, microRNAs (miRNAs) are emerging as key players.

Purpose of the Study:

  • To review the relationship between microRNAs (miRNAs) and the response to targeted cancer therapies.
  • To explore the role of miRNAs in mediating resistance to cancer treatments.
  • To discuss the potential of miRNAs as predictive biomarkers for therapy outcomes.

Main Methods:

  • Literature review of studies investigating miRNAs in cancer therapy response and resistance.
  • Analysis of molecular mechanisms linking miRNA dysregulation to drug resistance.
  • Synthesis of current evidence on miRNA-based prediction of treatment efficacy.

Main Results:

  • Evidence suggests specific miRNAs can predict patient response to targeted drugs.
  • Altered miRNA expression is implicated in various resistance mechanisms.
  • miRNAs can influence drug sensitivity through direct or indirect modulation of signaling pathways.

Conclusions:

  • MicroRNAs represent a promising avenue for predicting and overcoming cancer therapy resistance.
  • Further research into miRNA biomarkers could personalize cancer treatment strategies.
  • Targeting miRNAs may offer novel therapeutic approaches to enhance drug efficacy.

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 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...

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...

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 ATP-dependent...
