ABSTRACT
Viruses utilize clever strategies of interacting with various cellular factors, to remodel an organelle function, for the establishment of successful infection. In recent decades, numerous studies revealed the exploitation of the peroxisomal compartment by viruses. Epstein-Barr virus (EBV) is a ubiquitous virus linked with various cancers and neurological disorders. Till now, there is no report regarding the impacts of EBV infection on peroxisomal compartment. Therefore, we investigate the modulation of peroxisomal proteins in EBV transformed cell lines and during acute EBV infection. EBV positive Burkitt lymphoma cells of different origins as EBV transformed cells along with EBV negative Burkitt lymphoma cells as a control were used in this study. For acute EBV infection experiments, we infected peripheral blood mononuclear cells with EBV for three days. Thereafter, analyzed the gene expression patterns of peroxisomal proteins using qPCR. In addition, quantification of lipid content was performed by using fluorescence microscopy and biochemical assay. Our results revealed that, the peroxisomal proteins were distinctly regulated in EBV transformed cells and during acute EBV infection. Interestingly, PEX19 was significantly upregulated in EBV infected cells. Further, in correlation with the altered expression of peroxisomes proteins involved in lipid metabolism, the EBV transformed cells showed lower lipid abundance. Conversely, the lipid levels were increased during acute EBV infection. Our study highlights the importance of investigating the manipulation of the peroxisomal compartment by putting forward various differentially expressed proteins upon EBV infection. This study provides a base for further investigation to delve deeper into EBV and peroxisomal interactions. The future research in this direction could provide involvement of novel signaling pathways to understand molecular changes during EBV mediated pathologies.
