Metabolism of oxidative stress is necessary for cellular survival. We have previously utilized the zebrafish as a model of the oxidative stress response. In this study, we found that gata1-expressing erythroid cells contributed to a significant proportion of total-body oxidative stress when animals were exposed to a strong pro-oxidant. RNA-seq of zebrafish under oxidative stress revealed the induction...
Since most oncogenic viruses persist as extrachromosomal covalently closed circular DNA (cccDNA) in tumor cells, we developed an assay to visualize and identify cccDNA in primary lymphomas. We identified concatemers of the mitochondrial genome in all samples analyzed, but not in normal lymphocytes. One AIDS-associated lymphoma (EL) was further studied in detail as its mitochondrial genome consisted...
