Interactomes of GluA1 and GluA3 subunit containing AMPARs reveal distinct protein composition

Project description:The AMPA glutamate receptor (AMPAR) is the major type of synaptic excitatory ionotropic receptor in the brain. The most abundant AMPAR subtypes in the hippocampus are GluA1/2 and GluA2/3 heterotetramers. Each subtype contributes differentially to mechanisms of synaptic plasticity, which may be in part caused by how these receptors are regulated by specific associated proteins. A broad range of AMPAR interacting proteins have been identified and several were shown to affect biogenesis, AMPAR trafficking, and channel properties, alone or in distinct assemblies, and several revealed preferred binding to specific AMPAR subunits. To date, a systematic separate interactome analysis of the major GluA1/2 and GluA2/3 AMPAR subtypes is lacking. To reveal interactors belonging to specific AMPAR sub-complexes, we performed both quantitative and interaction proteomics on hippocampi of wildtype and GluA1- or GluA3 knock-out mice. Whereas GluA1/2 receptors co-purified TARP-γ8, PRRT1 and CNIH2 with highest abundances, GluA2/3 receptors revealed strongest co-purification of CNIH2, TARP-γ2, and OLFM1. Further analysis revealed that TARP-γ8-PRRT1 can interact directly, and co-assemble into an AMPAR subcomplex especially near the synapse.

Modelling Premature Cardiac Aging with Induced Pluripotent Stem Cells From a Hutchinson-Gilford Progeria Syndrome Patient

Project description:Hutchinson-Gilford Progeria Syndrome (HGPS) is a rare genetic disorder that causes accelerated aging and a high risk of cardiovascular complications. However, the underlying mechanisms of cardiac complications of this syndrome are not fully understood. This study modeled HGPS using cardiomyocytes (CM) derived from induced pluripotent stem cells (iPSC) derived from a patient with HGPS and characterized the biophysical, morphological, and molecular changes found in these CM compared to CM derived from a healthy donor. Electrophysiological recordings revealed that the HGPS CM was functional and had normal electrophysiological properties. Electron tomography showed nuclear morphology alteration and 3D reconstruction of electron tomography images indicated structural abnormalities in HGPS CM mitochondria. High-resolution respirometry with isolated CM derived from three distinct cellular differentiations suggests that HGPS-CM had a tendency of lower oxygen consumption capacity. However, there was no difference in mitochondrial content as measured by Mitotracker. Telomere length was measured using qRT-PCR, and no difference was found in either the iPSCs or the CM from HGPS when compared to the control. Proteomic analysis was carried out in a high-resolution system using Liquid Chromatography Tandem Mass Spectrometry (LC-MS/MS). The proteomics data show distinct group separations and protein expression differences between HGPS and control-CM, highlighting changes in ribosomal, TCA cycle, and amino acid biosynthesis, among other modifications. Our findings show that iPSC-derived cardiomyocytes from a Progeria Syndrome patient have significant changes in mitochondrial morphology and protein expression, implying novel mechanisms underlying premature cardiac aging

Comprehensive systems biology analysis of a seven-month cigarette smoke inhalation study in C57BL/6 mice.

Project description:Combustible cigarette smoking has major impact on human health. In order to reduce smoking-related health risk, the tobacco industry is developing modified risk tobacco products (MRTP). To assess the potential of such a prototype (pMRTP) to reduce health risk, we used C57BL/6 mice, model of chronic obstructive pulmonary disease (COPD), in a systems toxicology approach to investigate in a large, controlled study, classical toxicology end points in parallel to transcriptomics, lipidomics, and proteomics profiles in mice exposed to conventional cigarette smoke (3R4F) or a pMRTP aerosol for up to 7 months. We also included a cessation group and a switching-to-pMRTP group (after 2 months of 3R4F exposure), in addition to the control (fresh air exposed) group, to understand the potential benefit of switching to pMRTP for smokers who cannot or do not want to quit smoking. For quantitative proteomics analysis with the iTRAQ method, lung tissue samples from six mice (ie, six biological replicates) were analyzed for each exposure condition and time point (months 1, 3, 5, and 7 for 3R4F and pMRTP exposure and months 3, 5, and 7 for cessation and switch).

RNA-seq and RRBS of developing zebrafish larval brain and WGBS of 4 week old WT and dnmt3aa/dnmt3ab CRISPR/CAS9 KO brain

Project description:DNA methylation predominantly occurs at CG dinucleotides in vertebrate genomes, however, non-CG methylation (mCH) is also detectable in vertebrate tissues, most notably in the nervous system. In mammalian brains, it is well established that: i) mCH is targeted to CAC trinucleotides by DNMT3A, ii) enriched in gene bodies and repetitive elements, and iii) associated with transcriptional repression. However, the possible conservation of these mCH features in zebrafish is largely unexplored and has yet to be functionally demonstrated. In this study, we analyse the transcriptomes (RNA-seq) and methylome (RRBS) of developing zebrafish larvae (1-6 weeks) and adult brain (6 month). We additionally elucidate a role for dnmt3aa/dnmt3ab in mCH deposition via CRISP/CAS9 KO and WGBS of 4 week old brains

Project description:Transcriptome profiling of HL60 cells at the yearly time points of ATRA treatment (30 min and 1 h) allows to unveil molecular mechanisms of the onset of granulocytic maturation. Transcriptomic techniques are characterized by high sensitivity and allow for detection of low-abundant molecules, such as nuclear transcription factors.

Physiological profile of the coronary artery and internal thoracic artery endothelial cells as a basis for the structural and functional congrunce of the arterio-arterial continuum

Project description:Currently, it is well established that human endothelial cells (ECs) are characterised by a significant heterogeneity between distinct blood vessels, e.g., arteries, veins, capillaries, and lymphatic vessels. Further, even ECs belonging to the same lineage but grown under different flow patterns (e.g., laminar and oscillatory or turbulent flow) ostensibly have distinct molecular profiles defining their physiological behaviour. Human coronary artery endothelial cells (HCAEC) and human internal thoracic artery endothelial cells (HITAEC) represent two cell lines inhabiting atheroprone and atheroresistant blood vessels (coronary artery and internal thoracic artery, respectively). Resistance of the internal mammary artery to atherosclerosis has been largely attributed to the protective phenotype of HITAEC which reportedly produce higher amounts of vasodilators including nitric oxide (NO) through the respective signaling pathways. However, this hypothesis has not been adequately addressed hitherto as proteomic profiling of HCAEC and HITAEC in a head-to-head comparison setting has not been performed.
