RNA sequencing analysis of HEK293T cells infected with a lentivirus coding the BRCT domain from Leishmania major Pes protein

ABSTRACT: Given the prevalence of leishmaniasis and cancer, the co-existence of these two diseases may be merely coincidental. However, a number of epidemiological studies suggest that an association between these two entities does exist. Mammalian PES protein has been reported to be involved in different cellular processes such as cell cycle regulation. Its BRCT domain has been identified as a key factor in DNA damage-responsive checkpoints. We aimed to elucidate the hypothetical oncogenic character of this BRCT domain from Leishmania major PES protein (LmPES) on the host cells. For this purpose, we generated a lentivirus carrying this BRCT domain sequence (lentiBRCT) and a lentivirus expressing the lucifarese protein (lentiLuc), as control. Then, HEK293T mammal cells were infected with these lentivirus. Gene expression profiling analysis revealed that BRCT domain from LmPES protein altered the expression of proliferation, survival and chemoresistance related genes. In addition, RNA sequencing study showed a down-regulation of mitochondrial genes in the BRCT domain expressing cells triggering a mitochondrial dysfunction. Altogether, our results reinforce the idea that in eukaryotes, horizontal gene transfer may be also achieved by parasitism like Leishmania infection driving therefore to some crucial biological changes such as proliferation and drug resistance.

Project description:modENCODE_submission_3157 This submission comes from a modENCODE project of Michael Snyder. For full list of modENCODE projects, see http://www.genome.gov/26524648 Project Goal: We are identifying the DNA binding sites for 300 transcription factors in C. elegans. Each transcription factor gene is tagged with the same GFP fusion protein, permitting validation of the gene's correct spatio-temporal expression pattern in transgenic animals. Chromatin immunoprecipitation on each strain is peformed using an anti-GFP antibody, and any bound DNA is deep-sequenced using Solexa GA2 technology. For data usage terms and conditions, please refer to http://www.genome.gov/27528022 and http://www.genome.gov/Pages/Research/ENCODE/ENCODEDataReleasePolicyFinal2008.pdf EXPERIMENT TYPE: CHIP-seq.
