Microtubules (MTs) are hollow cytoskeletal filaments assembled from αβ-tubulin heterodimers. Tau, an unstructured protein found in neuronal axons, binds to MTs and regulates their dynamics. Aberrant Tau behavior is associated with neurodegenerative dementias, including Alzheimer's. Here, we report on a...

Neuronal active Caspase-6 (Casp6) is associated with Alzheimer disease (AD), cognitive impairment, and axonal degeneration. Caspase-1 (Casp1) can activate Casp6 but the expression and functionality of Casp1-activating inflammasomes has not been well-defined in human neurons. Here, we show that primary...

To identify glucocorticoid receptor (GR)-associated chromatin sequences and target genes in primary human abdominal subcutaneous fat. GR chromatin immunoprecipitation (ChIP)-sequencing (seq) methodology in subcutaneous human adipocytes treated ex vivo with dexamethasone (dex) was optimized to identify genome-wide dex-dependent GR-binding regions...

SUMOylation is a reversible post-translational modification (PTM) regulating all nuclear processes. Identification of SUMOylation sites by mass spectrometry (MS) has been hampered by bulky tryptic fragments, which thus far necessitated the use of mutated SUMO. Here we present a SUMO-specific...

Commensal oral biofilms, defined by the absence of pathology-related phenotypes, are ubiquitously present. In contrast to pathological biofilms commensal biofilms are rarely studied. Here, the effect of the initial inoculum and subsequent growth conditions on in vitro oral biofilms was...

Cell transplantation has been suggested as an alternative therapy for temporal lobe epilepsy (TLE) because this can suppress spontaneous recurrent seizures in animal models. To evaluate the therapeutic potential of human neural stem/progenitor cells (huNSPCs) for treating TLE, we transplanted...

For quantification of intracellular metabolites, mass spectrometry combined with liquid chromatography, capillary electrophoresis, or gas chromatography is currently the method of choice, especially when combined with stable isotope-labeled internal standards (SIL-ISs). Due to the difficulties in finding a biological matrix...

The intracellular bacterial pathogen Shigella infects and spreads through the human intestinal epithelium. Effector proteins delivered by Shigella into cells promote infection by modulating diverse host functions. We demonstrate that the effector protein OspB interacts directly with the scaffolding protein...

We used a proteomics approach to identify the binding partners of Trypanosoma brucei 14-3-3 (Tb14-3-3) which led to the identification of a novel kinase, AKB1. The binding between these two proteins was mediated by an amphipathic groove structure in Tb14-3-3...

It is now well established that guanine nucleotides are allosteric effectors of the vinca alkaloid-induced self-association of tubulin. GDP enhances self-association for vinblastine-, vincristine- and vinorelbine-induced spiral assembly relative to GTP by 0.90 +/- 0.17 kcal/mol [Lobert et al. (1996)...

We previously identified MGL_1304 secreted by Malassezia globosa as a sweat antigen for patients with atopic dermatitis (AD) and cholinergic urticaria (ChU). However, purifying native MGL_1304 from human sweat or culture supernatant of M. globosa (sup-MGL_1304) is costly and time-consuming....

The hallmark of enteropathogenic Escherichia coli (EPEC) infection is the formation of actin-rich pedestal-like structures, which are generated following phosphorylation of the bacterial effector Tir by cellular Src and Abl family tyrosine kinases. This leads to recruitment of the Nck-WIP-N-WASP...

Most complex disease-associated genetic variants are located in non-coding regions and are therefore thought to be regulatory in nature. Association mapping of differential allelic expression (AE) is a powerful method to identify SNPs with direct cis-regulatory impact (cis-rSNPs). We used...

Allele-specific (AS) assessment of chromatin has the potential to elucidate specific cis-regulatory mechanisms, which are predicted to underlie the majority of the known genetic associations to complex disease. However, development of chromatin landscapes at allelic resolution has been challenging since...
