Identifying the HIV-Resistance-Related Factors and Regulatory Network via Multi-Omics Analyses

Area of Science:

• Virology
• Immunology
• Genetics

Background:

• Understanding HIV-1 viral-host interactions is crucial for developing effective therapies.
• The regulatory networks of HIV resistance and infection factors are not well understood.
• Host dependency factors (HDFs) and restriction factors play key roles in HIV pathogenesis.

Purpose of the Study:

• To elucidate the regulatory network of HIV-1 resistance and infection.
• To identify potential host factors and pathways involved in HIV-1 pathogenesis.
• To uncover novel therapeutic targets for HIV/AIDS treatment.

Main Methods:

• Integrated analysis of multiple HIV-related omics datasets (transcriptome, DNA methylation, miRNA, ChIP-seq).
• Differential expression analysis, functional annotation, and protein-protein interaction network analysis.
• Identification and validation of key genes and regulatory pathways.

Main Results:

• Identified 25 potential HIV-resistance-related genes and 24 HIV-infection-related hub genes.
• Pinpointed key differentially methylated genes, microRNAs, and significant pathways in HIV resistance.
• Validated RHOA, RAD51, GATA1, IRF4, and CXCL8 as HDFs or restriction factors; JUN, EGF, and PLEK are also implicated.

Conclusions:

• Uncovered gene signatures and regulatory networks associated with HIV-1 resistance.
• Identified potential host dependency factors and restriction factors influencing HIV-1 infection.
• Suggests novel targets for the development of new HIV/AIDS therapies.
