Insights

MicroRNAs (miRNAs) are small RNAs regulating genes, crucial in cancer development. This review explores miRNA roles in tumorigenesis and their potential as cancer therapeutics, alongside current clinical challenges.

Area of Science:

  • Molecular Biology
  • Genetics
  • Oncology

Background:

  • MicroRNAs (miRNAs) are key regulatory non-coding RNAs controlling gene expression.
  • miRNAs are implicated as master regulators in cellular processes, including tumor initiation, progression, and metastasis.
  • Aberrant miRNA expression is common in various cancers, with miRNAs acting as oncogenes or tumor suppressors.

Purpose of the Study:

  • To review the multifaceted roles of miRNAs in tumorigenesis.
  • To examine current miRNA-based therapeutic strategies for cancer treatment.
  • To discuss the advantages and challenges of clinical miRNA applications.

Main Methods:

  • Literature review of scientific publications on miRNA functions in cancer.
  • Analysis of studies investigating miRNA deregulation in various tumor types.
  • Evaluation of preclinical and clinical data on miRNA-targeted cancer therapies.

Main Results:

  • miRNAs significantly influence multiple stages of cancer development.
  • Several miRNA-based therapies are under investigation, showing promise for cancer management.
  • The clinical translation of miRNA therapeutics faces hurdles including delivery and specificity.

Conclusions:

  • miRNAs are critical players in cancer biology and represent a promising avenue for novel cancer therapies.
  • Further research is needed to overcome challenges and fully realize the therapeutic potential of miRNAs in oncology.
  • miRNA-based strategies offer a unique approach to cancer treatment, complementing existing modalities.

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 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...

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...

Microorganisms in Medicine and Therapeutics

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.
