Project description:This dataset investigates the transcriptional effect of mitochondrial 12S rRNA hypermethylation, both by overexpressing the mitochondrial methyltransferase mtTFB1 in HeLa cells and by using A1555G cybrids, where the 12S rRNA is hypermethylated. HeLa cells overexpressing a methyltransferase-deficient mtTFB1 (mtTFB1[G65A]) and wild-type A1555A cybrids were used as controls.

Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
Project description:Transcriptome profiling is a sensitive strategy to uncover the change of mitochondrial to nucleus signaling due to the minor alternation of mitochondrial OXPHOS function. Therefore, we hypothesized that even a minor alternation of OXPHOS function can also remold transcriptome profiles in m.14487T>C mutant cybrid when compared with control cybrids. Our data suggest that a comparable mitochondrial OXPHOS function between m.14487T and m.14487C cybrids is not because of compensatory boost of mitochondrial biogenesis in m.14487C cybrids.
Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression.
