MetabolomicsPRODH regultes naive pluripotency by influencing mitochondrial oxidative phosphorylation (Untargeted metabolomics)

Naïve human embryonic stem cells (hESCs) that resemble the pre-implantation epiblasts are fueled by a combination of aerobic glycolysis and oxidative phosphorylation, but their mitochondrial regulators are poorly understood. Here we report that, proline dehydrogenase (PRODH), a mitochondria-local...

MetabolomicsOxidative phosphorylation is a metabolic vulnerability of endocrine therapy and palbociclib resistant metastatic breast cancers
Resistance to endocrine treatments and CDK4/6 inhibitors is considered a near-inevitability in most patients with estrogen receptor positive breast cancers (ER + BC). By genomic and metabolomics analyses of patients' tumours, metastasis-derived patient-derived xenografts (PDX) and isogenic cell line...

ProteomicsPhosphorylation ratio determination in fresh frozen and formalin-fixed paraffin embedded tissue with targeted mass spectrometry
Formalin-fixed paraffin embedded (FFPE) tissues are routinely prepared and collected for diagnostics in pathology departments. Therefore, FFPE tissues are the most accessible research sources in pathology archives. In this study we investigated whether we can apply a targeted and quantitative parall...

TranscriptomicsPathways leading to phosphorylation of p450c17 and to the post-translational regulation of androgen biosynthesis
Cytochrome P450c17 (P450c17) is the single enzyme that catalyzes steroid 17alpha-hydroxylase and 17,20 lyase activities and hence is the crucial decision-making step that determines the class of steroid made in a steroidogenic cell. Although both activities are catalyzed on a single active site, the...

TranscriptomicsPhosphorylation of MeCP2 at Serine 80 regulates its chromatin association and neurological function
Mutations of MECP2 (Methyl-CpG Binding Protein 2) cause Rett Syndrome. As a chromatin associated multifunctional protein, how MeCP2 integrates external signals and regulates neuronal function remain unclear. While neuronal activity-induced phosphorylation of MeCP2 at serine 421 (S421) has been repor...

TranscriptomicsCTD tyrosine phosphorylation impairs termination factor recruitment to transcribing RNA polymerase II
ChIP-chip was performed to identify the genomic binding locations for the termination factors Nrd1, and Rtt103, and for RNA polymerase (Pol) II phosphorylated at the tyrosine 1 and threonine 4 position of its C-terminal domain (CTD). In different phases of the transcription cycle, Pol II recruits di...

ProteomicsPhosphorylation ratio of pT vs pY ERK in MEK phosphorylation reaction determined by mass spectrometry
The purpose of this experiment is to determine the phosphorylation ratio of pT vs pY ERK present in ERK phosphorylation reaction by activated MEK E203K or MEK WildType. Aliquots were collected at 3 minutes 15 seconds, the time at which the mono-phosphorylated ERK is at its maximal. To determine the ...
