Project description:RNA sequencing of Wild Type (WT) and Actb-/- (KO) Mouse Embryonic Fibroblasts. Total RNA was sequenced to analyse noncoding transcripts and repeats
Project description:Using a supercritical fluid chromatography-mass spectrometry (SFC-MS)-based methodology, we quantified phosphoinositides (PIPs) species in LPIAT1 KO mouse embryonic fibroblasts (MEFs).
Project description:Using a supercritical fluid chromatography-mass spectrometry (SFC-MS)-based methodology, we quantified phosphoinositides (PIPs) species in mouse embryonic fibroblasts (MEFs) from WT or FIP200 KO mice during autophagosome formation.
Project description:The expression of inflammatory genes were downregulated in Hif-p4h-1 KO mouse embryonic fibroblasts both in normoxic and hypoxic condition, whereas the apoptosis regulation genes were upregulated or anti-apoptotic genes were downregulated in Hif-p4h-1 KO mouse embryonic fibroblasts. We used microarray to study the differential expression of genes in Hif-p4h-1 knockout versus WT mouse embryonic fibroblasts
Project description:This project looks at the effect a chemical modulator targeting PI3Kα has on the phosphoproteome of PI3Kα-WT and PI3Kα-KO MEFs. PI3K signalling is a critical regulator of numerous cellular processes such as proliferation, apoptosis, migration, invasion, metabolism, cell growth and autophagy. The PI3K pathway is frequently hyperactivated in cancer, commonly due to activating mutations or via loss of the lipid phosphatases that negatively regulate the pathway. We have recently identified a new small molecule modulator of the PI3K pathway and have used an unbiased phosphoproteomics approach to examine the impact of this compound on signalling pathways in cells that are wild-type and knockout for PI3K. Immortalised mouse embryonic fibroblasts (MEFs) isolated from PI3Kα-WT and PI3Kα-KO embryos were treated with and without the modulator (5 µM), exploring early (15 min) and late (4 h) time points. Insulin is a well-characterised activator of PI3K. Therefore, PI3Kα-WT MEFs were also treated with insulin (100 nM) as a positive control to compare with the PI3K modulator.
Project description:Spinocerebellar ataxia type 3 (SCA3) is a dominantly inherited neurodegenerative disorder caused by a polyglutamine-encoding CAG repeat expansion in the ATXN3 gene, which encodes a deubiquitinating enzyme, ATXN3, implicated in numerous quality control pathways. Several mechanisms have been proposed to explain the pathogenic role of mutant polyQ-expanded ATXN3 in SCA3 including disease protein aggregation, impairment of ubiquitin-proteasomal degradation and transcriptional dysregulation. A better understanding of the normal functions of this protein may shed light on SCA3 disease pathogenesis. To assess the potential normal role of ATXN3 in regulating transcription, we compared gene expression profiles in wildtype (WT) versus Atxn3 knockout (KO) mouse embryonic fibroblasts (MEFs).
