Endothelial c-Myc knockout disrupts metabolic homeostasis and triggers the development of obesity.

Obesity is a major risk factor associated with multiple pathological conditions including diabetes and cardiovascular disease. Endothelial dysfunction is an early predictor of obesity. However, little is known regarding how early endothelial changes trigger obesity.

c-Myc Drives inflammation of the maternal-fetal interface, and neonatal lung remodeling induced by intra-amniotic inflammation.

Intra-amniotic inflammation (IAI) is associated with increased risk of preterm birth and bronchopulmonary dysplasia (BPD), but the mechanisms by which IAI leads to preterm birth and BPD are poorly understood, and there are no effective therapies for preterm birth and BPD. The transcription factor c-Myc regulates various biological processes like cell growth, apoptosis, and inflammation. We hypothesized that c-Myc modulates inflammation at the maternal-fetal interface, and neonatal lung remodeling.

ADAM17 cytoplasmic domain modulates Thioredoxin-1 conformation and activity.

The activity of Thioredoxin-1 (Trx-1) is adjusted by the balance of its monomeric, active and its dimeric, inactive state. The regulation of this balance is not completely understood. We have previously shown that the cytoplasmic domain of the transmembrane protein A Disintegrin And Metalloprotease 17 (ADAM17cyto) binds to Thioredoxin-1 (Trx-1) and the destabilization of this interaction favors the dimeric state of Trx-1.

The Nuclear Proteome of White and Gray Matter from Schizophrenia Postmortem Brains.

Schizophrenia (SCZ) is a serious neuropsychiatric disorder that manifests through several symptoms from early adulthood. Numerous studies over the last decades have led to significant advances in increasing our understanding of the factors involved in SCZ. For example, mass spectrometry-based proteomic analysis has provided important insights by uncovering protein dysfunctions inherent to SCZ.

Ion Mobility-Enhanced Data-Independent Acquisitions Enable a Deep Proteomic Landscape of Oligodendrocytes.

Oligodendrocytes are a type of neuroglia that provide trophic support and insulation to axons in the central nervous system. The genesis and maturation of oligodendrocytes are essential processes for myelination and the course of CNS development. Using ion mobility-enhanced, data-independent acquisitions and 2D-nanoUPLC fractionation operating at nanoscale flow rates, we established a comprehensive data set of proteins expressed by the human oligodendroglia cell line MO3.

Proteomics and molecular tools for unveiling missing links in the biochemical understanding of schizophrenia.

Psychiatric disorders are one of the biggest burdens to society, with significant personal and economical costs. Schizophrenia (SCZ), among them, is still poorly understood, and its molecular characterization is crucial to improve patients' diagnosis and treatment. The combination of genetic, biochemical, and environmental factors leads to systemic alterations, which are yet to be fully comprehended.

Identification of potential targets for an anticoagulant pectin.

Unlabelled: Heparin is a sulfated polysaccharide of animal origin showing excellent anticoagulant properties. Although it strongly inhibits the coagulation cascade, its interaction with multiple sites results in several side effects. An ideal alternative compound should not only possess anticoagulant and antithrombotic activities, but also provide specific binding to components of the coagulation cascade to decrease side effects and facilitate the control of pharmacologic actions in patient's body.

Employing proteomics to unravel the molecular effects of antipsychotics and their role in schizophrenia.

Schizophrenia is an incurable neuropsychiatric disorder managed mostly by treatment of the patients with antipsychotics. However, the efficacy of these drugs has remained only low to moderate despite intensive research efforts since the early 1950s when chlorpromazine, the first antipsychotic, was synthesized. In addition, antipsychotic treatment can produce often undesired severe side effects in the patients and addressing these remains a large unmet clinical need.

A procoagulant chemically sulfated mannan.

Disorders of hemostasis can produce innumerous problems. Polysaccharides have been studied both as anticoagulant and as procoagulant agents. A mannan with a main chain of α-(1 → 6)-linked-Manp units, branched at O-2 mainly by side-chains of 2-O-linked-α-Manp units was chemically sulfated, structurally characterized by NMR and GC-MS (methylation, desulfation and methylation with trideuterated iodomethane), and tested in vitro and in vivo on blood coagulation models.
