Project description:The role of mitochondria dynamics and its molecular regulators remains largely unknown during naïve-to-primed pluripotent cell interconversion. Here we report that mitochondrial MTCH2 is a regulator of mitochondrial fusion, essential for the naïve-to-primed interconversion of murine embryonic stem cells (ESCs). During this interconversion, wild-type ESCs elongate their mitochondria and slightly alter their glutamine utilization. In contrast, MTCH2-/- ESCs fail to elongate their mitochondria and to alter their metabolism, maintaining high levels of histone acetylation and expression of naïve pluripotency markers. Importantly, enforced mitochondria elongation by the pro-fusion protein Mitofusin (MFN) 2 or by a dominant negative form of the pro-fission protein dynamin-related protein (DRP) 1 is sufficient to drive the exit from naïve pluripotency of both MTCH2-/- and wild-type ESCs. Taken together, our data indicate that mitochondria elongation, governed by MTCH2, plays a critical role and constitutes an early driving force in the naïve-to-primed pluripotency interconversion of murine ESCs.

Project description:Primordial genomic challenge compromises embryonic development and survival, and surveillance of deployed transcriptional programs may provide an early opportunity to forecast phenotype abnormalities. Here, comparisons between wild-type and calreticulin-ablated embryonic stem cells revealed transcriptome shifts precipitated by calreticulin loss. Bioinformatic analysis identified down and up-regulation in 1187 and 418 genes, respectively. Cardiovascular development precedes other organogenic programs, and examination of cardiogenic genes revealed a map of calreticulin-calibrated expression profiles that encompass the developmental regulators, Ccnd1, Ccnd2 and Notch1. Interrogation of primary function in the resolved network forecasted abnormalities during myocardial development. Whole embryo magnetic resonance imaging, verified by pathoanatomical analysis, diagnosed prominent ventricular septal defect. Correlation clustering and network resolution of probesets associated with protein folding/chaperoning and calcium handling demonstrated 14 and 19 genes, respectively, modulated by calreticulin deficiency. Calreticulin deletion provoked ontological re-prioritization of gene expression, molecular transport and protein trafficking that translated into multiple subcellular functional outcomes. Individual stem cell-derived cardiomyocytes lacking calreticulin demonstrated a disorganized contractile apparatus with mitochondrial paucity and architectural aberrations. Thus, bioinformatic deconvolution of primordial embryonic stem cell transcriptomes enables predictive phenotyping of defective developmental networks that coalesce from complex systems biology hierarchies.

Project description:To study effect of VRK1 deletion on spermatogenesis of the mouse, transciptomic analysis of genes in postnatal 8-day testicular cells of wild type and VRK1-deficient Mus musculus was performed. Gene expression in testes from from wild type and VRK1-deficient mutant Mus musculus, respectively, was measured. Four independent experiments for wild type and mutant, respectively, were performed.

Project description:Muscle (M), myotendinous (J) and tendon (T) tissues were isolated from murine wild-type soleus muscle-tendon units. Tissues were either: 1) fractionated prior to LC-MS/MS analysis of the CS and IN fractions; or 2) homogenized prior to LC-MS/MS analysis of the homogenate. Samples were analyzed by Q Exactive (Thermo Scientific).
