Summary
This study identifies novel microRNA-gene interactions for detecting latent tuberculosis infection (LTBI). These findings could lead to more sensitive and cost-effective diagnostic tests for tuberculosis in Taiwan.
Area of Science:
- Molecular biology
- Infectious diseases
- Genomics
Background:
- Tuberculosis (TB) remains a leading infectious cause of death globally.
- Latent TB infection (LTBI) affects 90% of infected individuals, with a 10% risk of progressing to active disease.
- Existing molecular studies on TB pathogenesis show variable results due to complex factors.
Purpose of the Study:
- To systematically analyze gene and microRNA profiles in healthy individuals, active TB, and LTBI patients.
- To identify novel molecular interactions as potential biomarkers for TB and LTBI detection.
- To facilitate the development of sensitive, efficient, and cost-effective diagnostic assays for the Taiwanese population.
Main Methods:
- Systematic analysis of gene and microRNA expression profiles.
- In silico analysis using public microRNA knowledge bases and literature data.
- Identification of specific microRNA-gene interactions targeting blood and lung tissues.
Main Results:
- Several microRNA-gene interactions were identified with specificity for TB and LTBI.
- Some identified interactions represent novel molecular targets.
- These interactions show potential as biomarkers for TB and LTBI.
Conclusions:
- Novel microRNA-gene interactions offer potential for TB and LTBI diagnosis.
- The findings support the development of advanced diagnostic tools for tuberculosis.
- This research specifically benefits the Taiwanese population by aiming for tailored diagnostic solutions.

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

Ribosome Profiling
3.2K
Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.

MicroRNAs
3.0K
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...

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:
