Oocyte maturation is accompanied by a transition from mRNA stability to instability. We investigated the role of DCP1A and DCP2, proteins responsible for mRNA decapping, in mRNA destabilization during mouse oocyte maturation.
Maternally recruited DCP1A and DCP2 contribute to messenger RNA degradation during oocyte maturation and genome activation in mouse.

View SamplesDouble-stranded RNA (dsRNA) can enter different pathways in mammalian cells, including sequence-specific RNA interference, sequence-independent interferon response and editing by adenosine deaminases. To assess the potential of expressed dsRNA to induce interferon stimulated genes in somatic cells, we performed microarray analysis of HEK293 and HeLa cells transfected with a MosIR plasmid expressing an mRNA with a long inverted repeat structure in its 3UTR (MosIR) or with a parental MosIR plasmid (without inverted repeat) as a control.
dsRNA expression in the mouse elicits RNAi in oocytes and low adenosine deamination in somatic cells.

View SamplesWe analyzed a role of histone deacetylases in alternative splicing regulation. Using human exon arrays we identified a list of 683 genes whose splicing changes after HDAC inhibition with sodium butyrate.
Histone deacetylase activity modulates alternative splicing.

View SamplesWe analyzed a role of Brd2 protein in transcription and alternative splicing. 289 genes change alternative splicing after Brd2 knockdown and 1459 genes alter gene expression compared to cells treated with negative control siRNA.
The C-terminal domain of Brd2 is important for chromatin interaction and regulation of transcription and alternative splicing.

View SamplesProgranulin mutations found in frontotemporal lobar degeneration (FTLD) cases typically result in heterozygous loss-of-function. To assess the impact of PGRN deficiency on gene expression, particularly of genes associated with lipid metabolism, in the brain, we sequenced the total RNA extracted from whole brains from 7-month-old female Grn+/+, Grn+/–, and Grn–/– mice and determined the differential expression of transcripts in PRGN-deficient (Grn+/- and Grn-/-) and wild type (Grn+/+) brains.

View SamplesWe address the molecular mechanisms through which MYC promotes loss of cell identity and acquisition of stem cell-like traits, favouring the onset of tumorigenesis, by performing gene expression profile analyses in a transition from WT IMEC, IMEC over-expressing MYC and mammospeheres formed from IMEC-MYC (named M2). We then investigated the global gene expression profile of the fraction of cells hyper-activating the WNT pathway in M2 spheres, compared to the ones with low activation
MYC-driven epigenetic reprogramming favors the onset of tumorigenesis by inducing a stem cell-like state.
