Résumé
The presence of latent HIV reservoirs continues to be the biggest obstacle to achieving an HIV cure. Thus, long non-coding RNAs (lncRNAs) may serve as the preferred targets for HIV latency reversal. The goal of the study was to identify prospective lncRNAs for subsequent in vitro molecular and functional characterization. RNA-sequencing was performed in latently HIV-infected monocytic cell line (U1) under stimulated and unstimulated condition using Illumina-HiSeqX platform, followed by its validation using qRT-PCR assay. Gene ontology (GO), KEGG pathway, and co-expression analyses were performed to identify the enriched biological processes and pathways in U1 cells post-stimulation with the latency reversal agent SAHA. A total of 3,576 and 1,467 significantly altered lncRNAs and protein-coding genes respectively, were identified in SAHA-stimulated U1 cells compared to unstimulated ones. The GO and KEGG pathway analyses of the differentially expressed protein-coding genes showed the enrichment of diverse biological processes and pathways respectively, in SAHA-stimulated U1 cells. Co-expression analysis between lncRNAs and protein-coding gene pairs, helped predict potential pathways with which these lncRNAs are associated. Further in vitro validation in HIV-infected monocytes showed that the expression of the top two candidate lncRNAs, LINC01231 and LINC00560, are specific to HIV infection. Transcriptome analysis revealed changes in the expression of numerous lncRNAs and protein-coding genes following stimulation with SAHA. Co-expression analysis identified candidate lncRNAs and their associated biological pathways. However, additional in vitro experimental exploration using gene knockdown strategies is needed to ascertain the specific role of LINC01231 and LINC00560 lncRNAs in latently infected monocytes.

BACKGROUND
The presence of latent HIV reservoirs continues to be the biggest obstacle to achieving an HIV cure. Thus, long non-coding RNAs (lncRNAs) may serve as the preferred targets for HIV latency reversal. The goal of the study was to identify prospective lncRNAs for subsequent in vitro molecular and functional characterization.
METHODS AND RESULTS
RESULTS
RNA-sequencing was performed in latently HIV-infected monocytic cell line (U1) under stimulated and unstimulated condition using Illumina-HiSeqX platform, followed by its validation using qRT-PCR assay. Gene ontology (GO), KEGG pathway, and co-expression analyses were performed to identify the enriched biological processes and pathways in U1 cells post-stimulation with the latency reversal agent SAHA. A total of 3,576 and 1,467 significantly altered lncRNAs and protein-coding genes respectively, were identified in SAHA-stimulated U1 cells compared to unstimulated ones. The GO and KEGG pathway analyses of the differentially expressed protein-coding genes showed the enrichment of diverse biological processes and pathways respectively, in SAHA-stimulated U1 cells. Co-expression analysis between lncRNAs and protein-coding gene pairs, helped predict potential pathways with which these lncRNAs are associated. Further in vitro validation in HIV-infected monocytes showed that the expression of the top two candidate lncRNAs, LINC01231 and LINC00560, are specific to HIV infection.
CONCLUSION
CONCLUSIONS
Transcriptome analysis revealed changes in the expression of numerous lncRNAs and protein-coding genes following stimulation with SAHA. Co-expression analysis identified candidate lncRNAs and their associated biological pathways. However, additional in vitro experimental exploration using gene knockdown strategies is needed to ascertain the specific role of LINC01231 and LINC00560 lncRNAs in latently infected monocytes.
