Identification of drug repurposing candidates for the treatment of polycystic kidney disease - Birinapant

ABSTRACT: Autosomal dominant polycystic kidney disease (ADPKD) is a leading cause of end-stage renal disease with limited treatment options. Drug repurposing offers a promising strategy to find effective treatments. We identified birinapant, bardoxolone methyl and salicylic acid as repurposing candidates for ADPKD and applied thermal proteome profiling to identify disease-relevant targets. Our results uncovered shared effects between the three drugs, including a thermal shift in ADP/ATP translocases (SLC25A4/5/6) caused by reduced ATP production. As expected, salicylic acid displayed a polypharmacological profile but also engaged enzymes along the N-linked glycosylation pathway and inhibited PTK2, an activator of the proliferative PI3K/Akt/mTOR pathway. Orthogonal assays and computational modelling confirmed these findings and located the binding site (499-504) of salicylic acid within PTK2’s ATP-binding pocket. Engagement of several targets was achieved at clinically relevant concentrations. We have identified novel targets of three repurposing candidates that contribute to the cyst growth reducing effects in preclinical ADPKD models and identify salicylic acid, the metabolite of aspirin, as the repurposing candidate with the most promising mechanisms of action. This dataset contains files from thermal proteome profiling after birinapant exposure.

Chemoproteomic screen to identify rabeprazole off-targets in intact HEK293 MSR cells

Project description:Proton pump inhibitors (PPIs) have become top-selling drugs worldwide. They are prodrugs activated by protonation in highly acidic environments. They inhibit stomach acid secretion by covalently modifying the gastric H+/K+-ATPase. However, little is known about alternative activation mechanisms and target proteins in non-acidic environments. Employing a chemoproteomic approach in living cells, we find rabeprazole to form covalent conjugates with numerous zinc-binding proteins. We show that one of the main target proteins, density-regulated protein (DENR), is conjugated to rabeprazole through a cysteine residue forming part of the zinc-binding site. We propose that zinc acts as a Lewis acid, obviating the need for low pH, to promote the activation of PPIs in non-acidic environments. Our findings may aid the understanding of secondary drug effects and/or the repurposing of PPIs.

Investigating the effect of molecular crowding agents on protein stability in a bacterial proteome

Project description:Molecular crowding refers to the restriction of space available for molecular mobility in solution due to the presence of other macromolecules. Crowding can influence biological phenomena such as protein stability and folding, diffusion, enzyme kinetics, molecular interactions, and phase separation. In contrast to many biochemical studies that employ dilute solutions comprising a small number of reactants, the cellular environment is considered to be highly crowded, with up to 40% of cell volume occupied by many thousands of proteins and other large biomolecules. We examined the protein stability effects of widely used cosolvents that are considered to act as molecular crowders for experimental purposes in a bacterial proteome (Cupriavidus necator) using the Thermal Proteome Profiling (TPP) method. While all six tested compounds (Ficoll 70, Ficoll 400, dextran 40, dextran 86, PEG 1, PEG 8) reduced the global mean melting temperature, significantly increased or decreased conformational stability was observed among distinct subsets of the proteome, with some individual proteins showing sensitivity to multiple crowding agents. Proteins displaying enhanced stability in the presence of crowding agents tended to be more hydrophobic, were more likely to show classic enzyme-like properties, and propensity for protein interactions. Our data support a direct binding/preferential exclusion model of enhanced stability, rather than alternative models based on viscosity or crowding.

A patient-derived 3D cyst model of polycystic kidney disease that mimics disease development, expresses relevant drug targets and responds to repurposing candidates

Project description:Autosomal dominant polycystic kidney disease (ADPKD) is the most common hereditary kidney disease. Its progressively expanding, fluid-filled renal cysts eventually lead to end-stage renal disease. Despite the relatively high prevalence, treatment options are currently limited to a single drug approved by the FDA and EMA. Here, we investigated human ADPKD patient-derived three-dimensional cyst cultures (3DCC) as an in vitro model for ADPKD and drug repurposing research. First, we analyzed the proteomes of 3DCC derived from healthy and diseased tissues. We then compared the protein expression profiles with those of reference tissues, mainly from the same patients. We quantified 290 proteins affecting drug disposition and proposed target proteins for drug treatment. Lastly, we investigated the functional response of the quantified target proteins after exposure to repurposing candidates in the 3DCC. Proteomic profiling of human 3DCC reflected previously reported pathophysiological alterations, including aberrant protein expression in inflammation and metabolic reprogramming. While the 3DCCs largely recapitulated the disease phenotype in vitro, drug transporter expression was reduced compared to in vivo conditions. Target proteins for proposed repurposing candidates showed similar expression in vitro and in tissues. Exposure to these repurposing candidates inhibited cyst swelling in vitro, supporting the suitability of the 3DCC for ADPKD drug screening. In summary, our results provide new insights into the ADPKD proteome and offer a starting point for further research to improve treatment options for affected individuals.

The ER-SURF pathway uses ER-mitochondria contact sites for protein targeting to mitochondria

Project description:Most mitochondrial proteins are synthesized on cytosolic ribosomes and imported into mitochondria in a post-translational reaction. Mitochondrial precursor proteins which use the ER-SURF pathway employ the surface of the endoplasmic reticulum (ER) as an important sorting platform. How they reach the mitochondrial import machinery from the ER is not known. Here we show that mitochondrial contact sites play a crucial role in the ER-to-mitochondria transfer of precursor proteins. The ER encounter structure (ERMES) and Tom70 are part of two cooperative and partially redundant ER-to-mitochondria transfer routes. If the ER-to-mitochondria transfer is prevented, many mitochondrial precursor proteins accumulate non-productively on the ER surface, resulting in mitochondrial dysfunction. Our observations support an active role of the ER in mitochondrial protein biogenesis.

STPP-UP: A alternative method for drug target identification using protein thermal stability

Project description:Thermal proteome profiling (TPP) has significantly advanced the field of drug discovery by facilitating proteome-wide identification of drug targets and off-targets. However, TPP has not been widely applied for high-throughput drug screenings, since the method is labor intensive and requires a lot of measurement time on a mass spectrometer. Here, we present Single-tube TPP with Uniform Progression (STPP-UP), which significantly reduces both the amount of required input material and measurement time, while retaining the ability to identify drug targets for compounds of interest.

MitoStores: Chaperone-controlled protein granules store mitochondrial precursors in the cytosol - Data Set 1: Global Proteome TMT

Project description:Hundreds of mitochondrial precursor proteins are synthesized in the cytosol and imported into mitochondria in a post-translational reaction. The early stages in mitochondrial protein targeting are poorly understood. Here we show that in baker’s yeast, the cytosol has the capacity to transiently store matrix-destined precursors in dedicated deposits which we named MitoStores. MitoStores are strongly induced when the import into mitochondria is competitively inhibited by clogging the mitochondrial import sites, but also found under physiological conditions when cells grow on non-fermentable carbon sources. MitoStores contain a specific subset of nuclear encoded mitochondrial proteins, in particular those with N-terminal mitochondrial targeting sequences. The cytosolic heat shock proteins Hsp42 and Hsp104 control MitoStore formation, thereby suppressing the toxic potential of accumulating mitochondrial precursor proteins. Thus, the cytosolic protein quality system plays an active role during early stages in mitochondrial protein targeting by the coordinated localized sequestration of mitochondrial precursor proteins.
