Insights

This study reveals shared molecular pathways between chronic thromboembolic pulmonary hypertension (CTEPH) and long-COVID, identifying key genes and immune cell regulators. Findings suggest common disease mechanisms and potential therapeutic targets for both conditions.

Area of Science:

  • Genomics
  • Molecular Biology
  • Pulmonary Medicine

Background:

  • Chronic thromboembolic pulmonary hypertension (CTEPH) and COVID-19 (coronavirus disease 2019) share potential molecular links.
  • The interrelation and shared pathogenetic mechanisms between CTEPH and long-COVID remain inadequately understood.

Purpose of the Study:

  • To identify shared molecular pathways and key genes between CTEPH and long-COVID.
  • To explore potential diagnostic and therapeutic strategies by analyzing molecular similarities.

Main Methods:

  • RNA sequencing (RNA-seq) data analysis of CTEPH and long-COVID cohorts (GSE130391, GSE169687).
  • Weighted Gene Co-Expression Network Analysis (WGCNA) to identify key module genes.
  • Differential gene expression analysis, hub gene identification, enrichment analysis, immune cell profiling, and drug prediction.

Main Results:

  • Identified 645 (long-COVID 16 weeks), 206 (long-COVID 24 weeks), and 1,543 differentially expressed genes (DEGs) in CTEPH.
  • Discovered 234 intersecting key module genes and three hub genes (DNAJA1, NDUFA5, SLC2A14) with high discriminatory power (AUC ≥ 0.7).
  • Revealed shared pathways in immune modulation, oxidative stress, and metabolic dysfunction, with activated CD8 T cells as critical regulators. Identified STAT1 and hsa-mir-23a-3p in regulatory networks and predicted potential therapeutics.

Conclusions:

  • Unraveled critical molecular linkages and shared pathogeneses between CTEPH and long-COVID.
  • Highlights the role of immune modulation, oxidative stress, and metabolic dysfunction in both conditions.
  • Provides a foundation for experimental validation and development of novel diagnostic and therapeutic strategies for CTEPH and COVID-19 sequelae.

Single Nucleotide Polymorphisms-SNPs01:05

Single Nucleotide Polymorphisms-SNPs

A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Anticoagulant Drugs: Low-Molecular-Weight Heparins

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

Pulmonary Hypertension: Classification and Pathogenesis01:30

Pulmonary Hypertension: Classification and Pathogenesis

Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

Treatment for Pulmonary Arterial Hypertension: Receptor Tyrosine Kinase Inhibitors and Calcium Channel Blockers

Receptor tyrosine kinase inhibitors (TKIs) and calcium channel blockers (CCBs) are two critical categories of drugs employed in the treatment of pulmonary artery hypertension (PAH). PAH is a disease that causes high blood pressure in the pulmonary arteries, resulting in chest pain, fatigue, and shortness of breath.
TKIs, such as imatinib (Gleevec), are particularly effective in tackling the growth and mitogenic factors that become upregulated in PAH patients. These factors contribute to the...

Viral Mutations00:36

Viral Mutations

A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...
