Abstract:
The number of effective drugs for the prevention and control of tuberculosis is very limited. Therefore, high-throughput screening for Mycobacterium tuberculosis drug targets is critical. In addition, determining the essential gene cluster is important for both understanding a survival mechanism and finding novel molecular targets for anti-tuberculosis drugs. In this study, we applied the pathway enrichment method to perform high throughput screening of genes encoding key molecules for potential drug targets for M. tuberculosis. Our results indicated 122 genes that existed in more than three pathways, while four existed in 11 pathways. We predicted 55 genes that are potentially essential genes. Four of them, namely, Rv0363c, Rv0408, Rv0409 and Rv0794c, had the highest probability to be essential genes, and thus further experimental validation is warranted.
Insights

Main Methods:
- Applied pathway enrichment analysis for high-throughput screening of genes.
- Focused on genes encoding key molecules within M. tuberculosis pathways.
- Utilized computational methods to predict essential genes.
Main Results:
- Identified 122 genes present in more than three pathways.
- Discovered four genes that are part of 11 pathways.
- Predicted 55 potentially essential genes in M. tuberculosis.
- Highlighted Rv0363c, Rv0408, Rv0409, and Rv0794c as high-probability essential genes.
Conclusions:
