Insights

MicroRNAs (miRNAs) are small RNAs regulating genes. Aberrant miRNA expression drives cancer, making them promising therapeutic targets for novel cancer treatments.

Area of Science:

  • Molecular Biology
  • Genetics
  • Oncology

Background:

  • MicroRNAs (miRNAs) are key post-transcriptional gene regulators.
  • Dysregulated miRNA expression is implicated in human cancer development.
  • miRNAs can function as oncogenes or tumor suppressors in cancer.

Purpose of the Study:

  • To explore the role of microRNAs in cancer.
  • To highlight miRNA-based cancer therapy as a novel therapeutic strategy.
  • To discuss the potential of miRNA modulation in cancer treatment.

Main Methods:

  • Review of current scientific literature on microRNAs and cancer.
  • Analysis of evidence supporting miRNA roles in oncogenesis and tumor suppression.
  • Examination of the therapeutic potential of targeting miRNA networks.

Main Results:

  • MicroRNAs are crucial regulators of gene expression.
  • Aberrantly expressed miRNAs are significantly involved in various human cancers.
  • Targeting single miRNAs can affect multiple cancer-related gene networks.

Conclusions:

  • MicroRNA dysregulation is a hallmark of cancer.
  • miRNA-based therapies offer a promising avenue for cancer treatment.
  • Modulating miRNA activity represents a new frontier in cancer research.

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...

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.

Microbial Corrosion

Microbiologically Influenced Corrosion (MIC) is a significant form of material degradation caused by the metabolic activities of microorganisms. This phenomenon poses substantial challenges across various industries, including oil and gas, maritime, and water treatment sectors.MIC occurs when microorganisms, such as bacteria, archaea, and fungi, colonize metal surfaces, forming biofilms that alter the local electrochemical environment. These biofilms can lead to the production of corrosive...
