Abstract

Insights

Genetic variations in specific human microRNAs (miRNAs) were investigated for their association with pulmonary tuberculosis (TB). No significant sequence differences were found in the selected miRNAs between TB patients and healthy individuals.

Area of Science:

  • Genetics
  • Molecular Biology
  • Immunology

Background:

  • MicroRNAs (miRNAs) are crucial regulators in disease development.
  • Human miRNAs can potentially inhibit Mycobacterium tuberculosis (Mtb) survival by targeting pathogen genes.
  • Mutations in miRNAs may impair Mtb gene inhibition, increasing susceptibility to tuberculosis (TB).

Purpose of the Study:

  • To investigate the genetic association between pulmonary TB and six specific human miRNA genes.
  • To determine if sequence variations in selected miRNAs correlate with the inhibition of critical Mtb genes in TB patients.

Main Methods:

  • Examined genetic association of pulmonary TB with hsa-miR-370, hsa-miR-520d, hsa-miR-154, hsa-miR-497, hsa-miR-758, and hsa-miR-593.
  • Focused on sequence variations in miRNAs predicted to interact with Mtb genes.

Main Results:

  • No significant differences in miRNA sequences were observed between TB patients and healthy individuals.
  • The study did not find a genetic association between the selected miRNA gene sequences and pulmonary TB.

Conclusions:

  • The lack of observed genetic association may be due to sample size limitations.
  • Future studies should address sample size and explore a broader selection of miRNA genes for a comprehensive understanding.

Pulmonary Tuberculosis I

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Pulmonary Tuberculosis V

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...

Pulmonary Tuberculosis II

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

MicroRNAs01:22

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...

Pulmonary Tuberculosis III

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:
