Insights

MicroRNAs (miRNAs) regulate gene expression and are implicated in disease pathogenesis. Understanding miRNA targets is crucial for their therapeutic potential in conditions like cardiac hypertrophy and failure.

Area of Science:

  • Molecular Biology
  • Genetics
  • Biochemistry

Background:

  • MicroRNAs (miRNAs) are key posttranscriptional gene regulators.
  • Over 600 human miRNAs identified, regulating approximately one-third of all messenger RNAs (mRNAs).
  • miRNA deregulation is linked to disease pathogenesis, offering diagnostic and prognostic value.

Purpose of the Study:

  • To review the role of miRNAs as major posttranscriptional regulators.
  • To discuss the impact of miRNAs on gene expression and cell function in cardiac hypertrophy and failure.
  • To highlight the therapeutic potential of targeting miRNAs.

Main Methods:

  • Literature review of miRNA research.
  • Analysis of miRNA roles in cardiac pathophysiology.
  • Discussion of current understanding and future directions in miRNA research.

Main Results:

  • miRNAs significantly impact gene expression and cellular functions.
  • miRNA expression patterns are altered in various diseases.
  • Specific mRNA targets and functions of many miRNAs are still under investigation.

Conclusions:

  • miRNAs are critical regulators of gene expression with significant roles in disease.
  • Further research into miRNA targets and functions is essential for therapeutic applications.
  • miRNAs hold promise for novel therapeutic strategies, particularly in cardiovascular diseases.

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.

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 specific...
