To systemically explore how RNA quality affects microarray assay results, a set of rat liver RNA samples with a progressive change in RNA quality was generated either by thawing frozen tissue or by ex vivo incubation of fresh tissue.
Characterization of the effect of sample quality on high density oligonucleotide microarray data using progressively degraded rat liver RNA.

View SamplesThe goal of this study was to determine the role of the X-linked epigenetic mediator, O-linked N-acetylglucosamine transferase (OGT) in establishment of trophoblast-specific sex differences in gene expression and to determine if sex differences in OGT and downstream epigenetic modifications contribute to sex differences in hypothalamic gene expression and development.

View SamplesThe combination of defined factors with small molecules targeting epigenetic factors is a strategy that has been shown to enhance optimal derivation of human iPSCs and could be used for therapeutic and regenerative medicine applications. In this study, we showed that a new first-in-class dual G9a/DNMT inhibitor CM272 compound improves the standard four-factor reprogramming efficiency of human fibroblast. The use of CM272 facilitates the generation of iPSC with only two factors, OCT4 and SOX2, allowing the removal of potentially oncogenic factors such as cMYC or KLF4. Taking a closer look at the early events occurring during cell reprogramming we demonstrated that treatment with our G9a/DNMT dual inhibitor induces heterochromatin relaxation, facilitates the engagement of OCT4 and SOX2 transcription factors to the genome and promotes mesenchymal to epithelial transition during cell reprogramming. Thus, the use of this new G9a/DNMT dual inhibitor compound may represent an interesting alternative for improving cell reprogramming.
Reversible dual inhibitor against G9a and DNMT1 improves human iPSC derivation enhancing MET and facilitating transcription factor engagement to the genome.

View SamplesWe have investigated the p53-dependent stress response in medium spiny neurons (MSNs) that degenerate in Huntingtons disease. To induce p53 signaling cascade, we have genetically inactivated by the Cre/loxP system the essential RNA polymerase I (Pol I) transcription factor TIF-IA, leading to stabilization of p53 and induction of p53-dependent apoptosis.
