Electrophile Signaling and Emerging Immuno- and Neuro-modulatory Electrophilic Pharmaceuticals

Yimon Aye, Jesse Poganik

With a lipid-rich environment and elevated oxygen consumption, the central nervous system (CNS) is subject to intricate regulation by lipid-derived electrophiles (LDEs). Investigations into oxidative damage and chronic LDE generation in neural disorders ha ...

Genome-wide Screens Implicate Loss of Cullin Ring Ligase 3 in Persistent Proliferation and Genome Instability in TP53-Deficient Cells

Sebastian Martin Waszak, Ruxandra-Andreea Lambuta

TP53 deficiency is the most common alteration in cancer; however, this alone is typically insufficient to drive tumorigenesis. To identify genes promoting tumorigenesis in combination with TP53 deficiency, we perform genome-wide CRISPR-Cas9 knockout screen ...

Differences in viral disinfection mechanisms as revealed by quantitative transfection of Echovirus 11 genomes

Urs von Gunten, Tamar Kohn, Jason Robert Torrey

Virus inactivation mechanisms can be elucidated by methods which measure the loss of specific virus functionality (e.g., host attachment, genome internalization, genome replication). Genome functionality is frequently assessed by PCR-based methods, which a ...

Preexisting variation in DNA damage response predicts the fate of single mycobacteria under stress

John McKinney, Neeraj Dhar, Giulia Manina

Clonal microbial populations are inherently heterogeneous, and this diversification is often considered as an adaptation strategy. In clinical infections, phenotypic diversity is found to be associated with drug tolerance, which in turn could evolve into g ...

Adaptive damage retention mechanism enables healthier yeast population

Riccardo Dainese

During cytokinesis in budding yeast (Saccharomyces cerevisiae) damaged proteins are distributed asymmetrically between the daughter and the mother cell. Retention of damaged proteins is a crucial mechanism ensuring a healthy daughter cell with full replica ...

Lymphoma Chemotherapy: Hungry Macrophages Strike the Final Blow

Michele De Palma, Florent Philippe Maurice Duval

Macrophages modulate tumor response to chemotherapy; in this issue, Lossos and colleagues show that high-dose alkylating agents instigate a synthetic lethal program in lymphoma cells that is independent of DNA damage and involves recruitment and priming of ...

Vertical Ionization Energies and Electron Affinities of Native and Damaged DNA Bases, Nucleotides, and Pairs from Density Functional Theory Calculations: Model Assessment and Implications for DNA Damage Recognition and Repair

Ursula Röthlisberger, Ivano Tavernelli, Polydefkis Diamantis

To assess the effect of an 8-oxoguanine (8OG) defect base on the vertical ionization energies (VIEs) and electron affinities (VEAs) of DNA, density functional theory calculations were carried out for native and defect DNA bases and nucleotides, as well as ...

Mechanisms protecting host cells against bacterial pore-forming toxins

Francisco De Magalhães Sarmento Ribeiro De Mesquita

Pore-forming toxins (PFTs) are key virulence determinants produced and secreted by a variety of human bacterial pathogens. They disrupt the plasma membrane (PM) by generating stable protein pores, which allow uncontrolled exchanges between the extracellula ...

A bi-terminal protein ligation strategy to probe chromatin structure during DNA damage

Beat Fierz, Sinan Kilic, Iuliia Boichenko, Carolin Christine Lechner

The cellular response to DNA damage results in a signaling cascade that primes chromatin for repair. Combinatorial post-translational modifications (PTMs) play a key role in this process by altering the physical properties of chromatin and recruiting downs ...

Label-Free Optofluidic Nanobiosensor Enables Real-Time Analysis of Single-Cell Cytokine Secretion

Hatice Altug, George Coukos, Xiaokang Li, Maria Soler Aznar

Single-cell analysis of cytokine secretion is essential to understand the heterogeneity of cellular functionalities and develop novel therapies for multiple diseases. Unraveling the dynamic secretion process at single-cell resolution reveals the real-time ...

The telomeric DNA damage response: Insights into telomere compaction and identification of novel damage signaling factors

Aleksandra Vancevska

Telomeres are dynamic nucleo-protein structures capping the ends of all eukaryotic chromosomes. Together with telomerase, they counteract replication-dependent telomere attrition. Additionally, they disguise the linear ends of the chromosome from the DNA d ...
