Insights

MicroRNAs (miRNAs) are key regulators in cancer, acting as oncogenes or tumor suppressors. miRNA-based therapies, using mimics or antagonists, offer new strategies for cancer treatment and diagnosis.

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 various cancer types, with roles as oncogenes (oncomirs) or tumor suppressors.
  • miRNA expression profiles hold potential as biomarkers for cancer classification, diagnosis, and prognosis.

Purpose of the Study:

  • To provide an overview of microRNA biogenesis.
  • To discuss the role of specific miRNAs in cancer development and progression.
  • To explore current and emerging miRNA-based therapeutic strategies for cancer.

Main Methods:

  • Literature review of preclinical research on microRNAs in cancer.
  • Analysis of miRNA biogenesis pathways.
  • Examination of miRNA mimics and antagonists for therapeutic applications.

Main Results:

  • miRNAs play a dual role in cancer, either promoting or suppressing tumor growth.
  • miRNA expression patterns can serve as diagnostic and prognostic biomarkers.
  • miRNA-based therapeutics aim to modulate miRNA activity to combat cancer.

Conclusions:

  • MicroRNAs represent a significant area of research in oncology.
  • Targeting miRNAs offers promising therapeutic avenues for cancer treatment.
  • Further research into miRNA biogenesis and function will advance cancer care.

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...

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.
