Nylon-3 Polymers to Treat Fungal Infections

UW–Madison researchers have found that nylon-3 polymers developed in their lab display potent antifungal activity against a broad spectrum of common fungal pathogens, with minimal toxicity towards mammalian cells. The polymers have some activity alone, and when used in combination with existing drugs provide synergistic effects against Candida albicans, Cryptococcus neoformans and Aspergillus fumigatus strains, including some resistant strains.

Synergistic combination offers efficacy with significantly reduced amounts of drug and corresponding toxicity, which could potentially expand the relevant patient population.

The polymers were designed to resemble host-defense peptides (HDPs), which are natural molecules that exhibit antimicrobial activities.

Analogs of Diptoindonesin G for Breast Cancer Drug Development

UW–Madison researchers have synthesized analogs of Dip G that have shown a greater ability than the parent molecule to decrease ERα expression and stabilize ERβ in cultured breast cancer cells. The compounds are active for ameliorating, attenuating and halting the growth/metastasis of breast cancers.

Physics ‘Office Hours’ educational learning platform

A physics education researcher at the University of Wisconsin-Green Bay has designed a novel and interactive app-based study aid platform for students in STEM disciplines. The platform’s interface is built around education research into how students conceptualize problems they do not understand. It is a novel tool to help students see why they are struggling with a particular problem, and what might help them solve it, rather than solving the problem for them. The team’s first working prototype, the Physics Office Hours app, has been designed for use in introductory-level college physics. The app is designed to mimic a scenario students might face during ‘office hours’ with a professor: Rather than offering an answer, the instructor guides the students through problems via a series of questions. A user-friendly online interface allows app content to be easily updated and changed over time and as more problem sets become available. In addition, the app architecture can easily be adapted to problem sets in other STEM disciplines and therefore serves as a platform technology.

Efficient In Vitro Assay for Antigen-Specific Tolerance

Building on their work, UW–Madison researchers have now developed a T cell-bound cytokine (T-CBC) assay for detecting and quantifying regulatory T cells specific to self-antigens or donor alloantigens. The new method comprises (a) culturing the subject’s T cells for 24 hours in the presence of one or more target antigens and (b) analyzing the cultured T cells for expression of a marker (EBi3; TGFβ/LAP) indicative of antigen-specific immune suppression.

Genetic Testing for Acquired Peripheral Neuropathy in Dogs

UW–Madison researchers have identified a single nucleotide polymorphism (SNP) that is predictive of APN syndrome in dogs, based on a genome-wide association study. Using a population of Labrador retrievers (56 cases and 26 controls), the researchers have shown that a SNP on CFA1 tags the causal variant for APN in the Labrador retriever breed.

New Protein Production Strategy for Plants

UW–Madison researchers have identified a new plant viral IRES that can facilitate the efficient expression of multiple proteins from a single mRNA. The researchers discovered the new IRES in the Triticum mosaic virus (TriMV), a wheat virus that expresses 10 proteins from a single mRNA strand.

High-Throughput Genome Editing and Engineering of Industrial Yeast, Other Fungi

UW–Madison researchers have developed expression cassettes that facilitate genome editing and sequence replacement in fungi at an extraordinarily high rate. Their HERP (Haploid Engineering Replacement Protocol) cassettes combine thymidine kinase (TK) enzyme with meganucleases, and permit hundreds of thousands of independent transformations to be obtained in a single experiment.

TK (from human Herpes Simplex Virus) serves as both a selectable and counter-selectable marker. Since the common ancestor of all fungi lacked the gene, the marker is likely of nearly pan-fungal utility. Relevant species should include Saccharomyces cerevisiae, Saccharomyces mikatae, Saccharomyces kudriavzevii, Saccharomyces uvarum and Neurospora crassa.

Generating Vasculogenic Cell Populations from Human Stem Cells

UW–Madison researchers have developed a method for generating substantially pure populations of vasculogenic cells (i.e., pericytes and smooth muscle cells) from induced pluripotent stem cells following their differentiation into mesenchymal colony-forming progenitors, called mesenchymoangioblasts (MABs).

The process includes culturing the progenitors in a serum-free medium under conditions that promote differentiation to MABs. Subsequently, the MABs are cultured in medium containing PDGFBB to obtain pericytes, or sphingosylphosphorylcholine (SPC) and transforming growth factor beta (TGFβ) to obtain smooth muscle cells.
