Nucleoside reverse transcriptase inhibitors (NRTIs)-induced expression profile of mitochondria-related genes in the mouse liver

These results suggest that nucleoside reverse transcriptase inhibitors -related effect on expression level of genes associated with mitochondrial functions was much greater in response to AZT/3TC combination treatment than AZT alone

Scholarcy highlights

  • Mitochondrial dysfunction has been implicated in the adverse effects of nucleoside reverse transcriptase inhibitors used to treat HIV-1 infections
  • To gain insight into the mechanism by which NRTIs alter mitochondrial function, the expression level of 542 genes associated with mitochondrial structure and functions was determined in the livers of p53 haplodeficient C3B6F1 female mouse pups using mouse mitochondria-specific oligonucleotide microarray
  • The genotype did not significantly affect the gene expression profile induced by AZT/3TC treatment
  • AZT/3TC altered the expression level of 153 genes with false discovery rate of less than 0.05, in contrast to only 20 genes by AZT alone. These results suggest that NRTI-related effect on expression level of genes associated with mitochondrial functions was much greater in response to AZT/3TC combination treatment than AZT alone
  • These results suggest that nucleoside reverse transcriptase inhibitors-related effect on expression level of genes associated with mitochondrial functions was much greater in response to AZT/3TC combination treatment than AZT alone
