Summary
Genetic variations in AKT1 (a key kinase in Mycobacterium tuberculosis growth) are linked to tuberculosis susceptibility. Specific AKT1 polymorphisms and haplotypes were more common in Chinese pulmonary TB patients, suggesting a genetic association.
Area of Science:
- Genetics
- Microbiology
- Immunology
Background:
- The serine/threonine kinase AKT1 is crucial for controlling the intracellular growth of Mycobacterium tuberculosis.
- Understanding genetic factors influencing tuberculosis susceptibility is vital for public health.
Purpose of the Study:
- To investigate the association between polymorphisms in the AKT1 gene and susceptibility to pulmonary tuberculosis (TB).
Main Methods:
- Genotyping of two single nucleotide polymorphisms (SNPs) in AKT1 (IVS3+18C>T and +726G>A) using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).
- Comparison of genotype and haplotype frequencies between Chinese pulmonary TB patients and ethnically matched controls.
Main Results:
- Pulmonary TB patients exhibited a significantly lower frequency of the IVS3+18 C/C genotype and a higher frequency of the C/T genotype compared to controls (P < 0.05).
- The T-A haplotype of AKT1 showed a significantly higher frequency in TB patients than in controls (P < 0.05).
Conclusions:
- Genetic polymorphisms in the AKT1 gene are associated with susceptibility to pulmonary tuberculosis in the studied Chinese population.
- These findings highlight a potential genetic predisposition to TB related to AKT1 variations.

01:31Pulmonary 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:

01:26Pulmonary Tuberculosis IV
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...

01:11Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase
Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...
01:23Tuberculosis
Tuberculosis (TB) remains a significant global health concern, primarily targeting the lungs and spreading through airborne transmission. Infection begins when aerosolized droplet nuclei, expelled by an individual with active TB, are inhaled by another person. These microscopic particles carry Mycobacterium tuberculosis, the causative agent of TB. Upon reaching the alveoli, the bacilli are engulfed by alveolar macrophages. However, due to their specialized lipid-rich cell wall, these pathogens...
01:29Pharmacogenetic Phenotypes: Alterations in Pharmacokinetics, Drug Targets and Biologic Milieu
Genetic variations significantly influence drug response through pharmacokinetics, receptor interactions, and biologic milieu modifications. Pharmacokinetic alterations impact drug metabolism and clearance, affecting efficacy and toxicity. Variants in drug-metabolizing enzymes, such as CYP2C9 and CYP2C19, alter drug activation and elimination. For example, CYP2C9 loss-of-function variants require lower warfarin doses to prevent excessive bleeding, while CYP2C19 variants reduce clopidogrel...

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.
