Insights
This study reveals molecular pathway crosstalk between COVID-19 and common comorbidities like diabetes and hypertension. Identifying shared targets aids in developing personalized treatments for severe COVID-19 cases with pre-existing conditions.
Area of Science:
- Molecular Biology
- Genomics
- Bioinformatics
Background:
- Pre-existing conditions like hypertension, diabetes, and cardiovascular diseases (CVDs) worsen COVID-19 outcomes.
- Lack of understanding of molecular interactions between COVID-19 and comorbidities hinders personalized treatment.
- Current therapeutic options for COVID-19 are limited, especially for patients with multiple health issues.
Purpose of the Study:
- To identify molecular pathway crosstalk between COVID-19 and major comorbid conditions.
- To predict shared pathways and key gene targets for personalized COVID-19 management.
- To explore drug repurposing opportunities for identified targets.
Main Methods:
- Utilized multi-omics data sets.
- Applied bioinformatics strategies to analyze pathway interactions.
- Predicted shared pathways and hub genes.
- Identified approved drugs for potential repurposing.
Main Results:
- Identified significant pathway crosstalk between COVID-19 and diabetes, hypertension, CVDs, chronic kidney diseases (CKDs), and cancers.
- Predicted shared pathways and hub gene targets for COVID-19 combined with specific comorbidities.
- Provided a list of approved drugs for identified targets, suggesting repurposing potential.
Conclusions:
- The identified shared pathways and targets offer potential for personalized COVID-19 management in patients with comorbid conditions.
- Drug repurposing based on these targets may provide new therapeutic avenues.
- Further evaluation is needed to validate these findings for clinical application.
- The methodology can be applied to other complex disease-disease interactions.
Abstract:
It is well established that pre-existing comorbid conditions such as hypertension, diabetes, obesity, cardiovascular diseases (CVDs), chronic kidney diseases (CKDs), cancers, and chronic obstructive pulmonary disease (COPD) are associated with increased severity and fatality of COVID-19. The increased death from COVID-19 is due to the unavailability of a gold standard therapeutic and, more importantly, the lack of understanding of how the comorbid conditions and COVID-19 interact at the molecular level, so that personalized management strategies can be adopted. Here, using multi-omics data sets and bioinformatics strategy, we identified the pathway crosstalk between COVID-19 and diabetes, hypertension, CVDs, CKDs, and cancers. Further, shared pathways and hub gene-based targets for COVID-19 and its associated specific and combination of comorbid conditions are also predicted towards developing personalized management strategies. The approved drugs for most of these identified targets are also provided towards drug repurposing. Literature supports the involvement of our identified shared pathways in pathogenesis of COVID-19 and development of the specific comorbid condition of interest. Similarly, shared pathways- and hub gene-based targets are also found to have potential implementations in managing COVID-19 patients. However, the identified targets and drugs need further careful evaluation for their repurposing towards personalized treatment of COVID-19 cases having pre-existing specific comorbid conditions we have considered in this analysis. The method applied here may also be helpful in identifying common pathway components and targets in other disease-disease interactions too.

Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
