Insights

MicroRNAs (miRNAs) are key regulators of brain function. Abnormalities in miRNA expression are linked to neurodevelopmental disorders, cognitive dysfunction, and psychiatric conditions, offering potential therapeutic targets.

Area of Science:

  • Neuroscience
  • Molecular Biology
  • Genetics

Background:

  • MicroRNAs (miRNAs) are critical non-coding RNAs influencing neuronal development, structure, and function.
  • Aberrant miRNA expression and regulation are implicated in psychiatric and neurodevelopmental disorders, alongside cognitive impairments.

Purpose of the Study:

  • To review evidence linking miRNA dysregulation to complex neurological and psychiatric conditions.
  • To explore the mechanistic roles of specific miRNAs and pathways in disease pathogenesis.

Main Methods:

  • Review of existing scientific literature and expression profiling studies.
  • Analysis of genetic etiology and miRNA-mediated gene regulation in patient cohorts.

Main Results:

  • Established connection between miRNA abnormalities and neurological/psychiatric disorders.
  • Identified potential miRNA-related pathways contributing to disease pathophysiology.

Conclusions:

  • MiRNA dysregulation is a significant factor in the pathogenesis of complex brain disorders.
  • Further research into miRNAs offers promising avenues for novel therapeutic strategies.

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...

Gut-Brain Axis

The gut–brain axis is a bidirectional communication system that connects the gastrointestinal tract and the brain. This interaction is mediated through multiple pathways, including the vagus nerve, hormonal signals, immune responses, and chemical messengers produced by gut microbes.Microbial Contributions to Brain FunctionGut microbiota contributes significantly to brain function by producing neuroactive compounds. These include neuroactive compounds that influence neurotransmitters such as...

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...
