RESEARCH SUMMARY

Epigenetic mechanisms—factors other than an individual’s DNA sequence—play a critical role in the regulation of gene expression and undergo routine disruption in cancer. Dr. Meier’s work focuses on the development of chemical approaches to study epigenetic signaling and its relationship to cellular metabolism. The goal of these studies is to better elucidate the underlying logic linking gene expression and metabolism, and apply this knowledge towards new approaches to cancer therapy, diagnosis, and chemoprevention.

Modifications in an Emergency: The Role of N1- Methylpseudouridine in COVID-19 Vaccines

Modifications in an Emergency: The Role of N1- Methylpseudouridine in COVID-19 Vaccines

Published Date

The novel coronavirus SARS-CoV-2, the cause of the COVID-19 pandemic, has inspired one of the most efficient vaccine development campaigns in human history. A key aspect of COVID-19 mRNA vaccines is the use of the modified nucleobase N1-methylpseudouridine (m1Ψ) to increase their effectiveness. In this Outlook, we summarize the development and function of m1Ψ in synthetic mRNAs. By demystifying how a novel element within these medicines works, we aim to foster understanding and highlight future opportunities for chemical innovation.

Harnessing Ionic Selectivity in Acetyltransferase Chemoproteomic Probes

Harnessing Ionic Selectivity in Acetyltransferase Chemoproteomic Probes

Published Date

Chemical proteomics provides a powerful strategy for the high-throughput assignment of enzyme function or inhibitor selectivity. However, identifying optimized probes for an enzyme family member of interest and differentiating signal from the background remain persistent challenges in the field. To address this obstacle, here we report a physiochemical discernment strategy for optimizing chemical proteomics based on the coenzyme A (CoA) cofactor. First, we synthesize a pair of CoA-based sepharose pulldown resins differentiated by a single negatively charged residue and find this change alters their capture properties in gel-based profiling experiments. Next, we integrate these probes with quantitative proteomics and benchmark analysis of “probe selectivity” versus traditional “competitive chemical proteomics.” This reveals that the former is well-suited for the identification of optimized pulldown probes for specific enzyme family members, while the latter may have advantages in discovery applications. Finally, we apply our anionic CoA pulldown probe to evaluate the selectivity of a recently reported small molecule N-terminal acetyltransferase inhibitor. These studies further validate the use of physical discriminant strategies in chemoproteomic hit identification and demonstrate how CoA-based chemoproteomic probes can be used to evaluate the selectivity of small molecule protein acetyltransferase inhibitors, an emerging class of preclinical therapeutic agents.

A Chemoproteomic Portrait of the Oncometabolite Fumarate

Published Date

Hereditary cancer disorders often provide an important window into novel mechanisms supporting tumor growth. Understanding these mechanisms thus represents a vital goal. Toward this goal, here we report a chemoproteomic map of fumarate, a covalent oncometabolite whose accumulation marks the genetic cancer syndrome hereditary leiomyomatosis and renal cell carcinoma (HLRCC). We applied a fumarate-competitive chemoproteomic probe in concert with LC–MS/MS to discover new cysteines sensitive to fumarate hydratase (FH) mutation in HLRCC cell models. Analysis of this dataset revealed an unexpected influence of local environment and pH on fumarate reactivity, and enabled the characterization of a novel FH-regulated cysteine residue that lies at a key protein–protein interface in the SWI-SNF tumor-suppressor complex. Our studies provide a powerful resource for understanding the covalent imprint of fumarate on the proteome and lay the foundation for future efforts to exploit this distinct aspect of oncometabolism for cancer diagnosis and therapy.

Photoinducible Oncometabolite Detection

Published Date

Dysregulated metabolism can fuel cancer by altering the production of bioenergetic building blocks and directly stimulating oncogenic gene-expression programs. However, relatively few optical methods for the direct study of metabolites in cells exist. To address this need and facilitate new approaches to cancer treatment and diagnosis, herein we report an optimized chemical approach to detect the oncometabolite fumarate. Our strategy employs diaryl tetrazoles as cell-permeable photoinducible precursors to nitrileimines. Uncaging these species in cells and cell extracts enables them to undergo 1,3-dipolar cycloadditions with endogenous dipolarophile metabolites such as fumarate to form pyrazoline cycloadducts that can be readily detected by their intrinsic fluorescence. The ability to photolytically uncage diaryl tetrazoles provides greatly improved sensitivity relative to previous methods, and enables the facile detection of dysregulated fumarate metabolism through biochemical activity assays, intracellular imaging, and flow cytometry. Our studies showcase an intersection of bioorthogonal chemistry and metabolite reactivity that can be applied for biological profiling, imaging, and diagnostics.

Chemical biology takes to the skies as drones to deliver drugs and visualize biological processes

Pharmacology by Chemical Biology

Published Date

The real voyage of discovery consists not in seeking new landscapes, but in having new eyes.

~ Marcel Proust

Pharmacology is a science deeply rooted not only in manipulating physiology but also in defining the mechanism of therapeutic compounds so that they may be more precisely deployed. For example, studies by Sydney Farber revealed the potential of antifolates as drugs for the treatment of childhood leukemia, which led to mechanistic efforts that defined dihydrofolate reductase as a drug target. This discovery in turn enabled the development of novel anticancer and antibacterial agents, as well as new methods for probing biology using inducible dimerization. In this special issue of Molecular Pharmaceutics, “Pharmacology by Chemical Biology”, we highlight a diverse collection of chemical advances which may be used to treat disease or study drug action, and thus impact our understanding of pharmacology.

Profiling Cytidine Acetylation with Specific Affinity and Reactivity

Published Date

The human acetyltransferase NAT10 has recently been shown to catalyze formation of N4-acetylcytidine (ac4C), a minor nucleobase known to alter RNA structure and function. In order to better understand the role of RNA acetyltransferases in biology and disease, here we report the development and application of chemical methods to study ac4C. First, we demonstrate that ac4C can be conjugated to carrier proteins using optimized protocols. Next, we describe methods to access ac4C-containing RNAs, enabling the screening of anti-ac4C antibodies. Finally, we validate the specificity of an optimized ac4C affinity reagent in the context of cellular RNA by demonstrating its ability to accurately report on chemical deacetylation of ac4C. Overall, these studies provide a powerful new tool for studying ac4C in biological contexts, as well as new insights into the stability and half-life of this highly conserved RNA modification. More broadly, they demonstrate how chemical reactivity may be exploited to aid the development and validation of nucleobase-targeting affinity reagents designed to target the emerging epitranscriptome.

Discovering Targets of Non-enzymatic Acylation by Thioester Reactivity Profiling

Published Date

The cover image illuminates the non-enzymatic “ghost writers” of lysine acylation. Meier et al. detail the development of a chemoproteomic strategy that harnesses thioester reactivity to discover candidate cellular targets of non-enzymatic acylation. Application of this approach reveals that glycolytic enzymes can be strongly inhibited by reactive thioesters, including the fatty acid precursor malonyl-CoA. This study provides new insights into the metabolic regulation of lysine acetylation, and highlights the utility of reactivity-based methods to define and manipulate non-enzymatic protein modifications in complex biological settings.

Metabolic regulation of histone acetyltransferases by endogenous Acyl-CoA cofactors

Published Date

Unraveling the metabolic regulation of lysine acetyltransferases (KATs). Montgomery et al. detail the application of a competitive chemoproteomic strategy to quantitatively characterize the interactions of acyl-CoA metabolites with cellular KAT enzymes. These studies reveal KATs are strongly inhibited by lipid-derived CoA analogs, an interaction that may have implications for the metabolic regulation of epigenetic signaling, and highlight the power of chemoproteomics to rapidly characterize metabolic-epigenetic interactions in complex biological contexts.
