The BCG vaccine has been used against tuberculosis (TB) for over a hundred years; however, it does not protect adults from pulmonary TB. To develop alternative vaccines against TB, we generated Mycobacterium tuberculosis H37Rv (Mtb)-derived vaccine strains by rationally deleting key virulent genes, resulting in single (SKO; ΔfbpA), double (DKO; ΔfbpA-ΔsapM), triple (TKO-D; ΔfbpA-ΔsapM-ΔdosR and TKO-Z; ΔfbpA-ΔsapM-Δzmp1), and quadruple (QKO; ΔfbpA-ΔsapM-Δzmp1-dosR) strains. To understand how macrophages, the host cells that defend against infection and process antigens for presentation to immune cells, respond to these vaccine strains, we performed transcriptomic analyses of mouse bone marrow-derived macrophages …

Uveal melanoma (UM) is a rare but frequently metastasizing cancer. Genome-wide association studies have identified three common genome-wide significant germline risk loci. Here, we perform a genome-wide association study on 401 new cases and conduct a meta-analysis with three independent previously published cohorts for a total sample size of 2,426 cases. We confirm the three previously identified risk loci and identify four additional genome-wide significant loci. We find that eye pigmentation-decreasing variants are systematically associated with increased UM risk and that selection for lighter pigmentation in the past 5,000 years explains about 73% of the difference in UM incidence between …

Salinity And Moisture Influence Co2 And Ch4 Emissions From High-Latitude Coastal Soils, B. N. Barr, K. C. Kelsey, A. J. Leffler, M. Petit Bon, K. H. Beard

Wildland Resources Faculty Publications

Sea level rise and more frequent and larger storms will increase saltwater flooding in coastal terrestrial ecosystems, altering soil-atmosphere CO₂ and CH₄ exchange. Understanding these impacts is particularly relevant in high-latitude coastal soils that hold large carbon stocks but where the interaction of salinity and moisture on greenhouse gas flux remains unexplored. Here, we quantified the effects of salinity and moisture on CO₂ and CH₄ fluxes from low-Arctic coastal soils from three landscape positions (two Wetlands and Upland Tundra) distinguished by elevation, flooding frequency, soil characteristics, and vegetation. We used a full factorial laboratory incubation experiment …

The Impacts Of Ocean Warming On Phytoplankton Dynamics And Links To Fisheries Management Around St Helena Island, South Atlantic Ocean, Shelby Bargo

The Plymouth Student Scientist

In the context of a rapidly changing climate, understanding how ocean warming is reshaping the foundation of marine ecosystems has never been more important. This research investigates factors contributing to ocean warming, and where anthropogenically influenced climate change plays a critical role in the functionality of the physical marine environment, phytoplankton, and trophodynamics throughout the pelagic zone. Phytoplankton, whilst microscopic, are vital; they are regulated by physical oceanographic factors that control their access to growth-limiting factors, such as nutrients. With the formidable climate-driven physical and biological changes occurring in the marine environment, alongside the decline in fish stocks, it is …

Soil-transmitted helminths (STHs) are intestinal parasites that affect over a billion people worldwide. STH control relies on microscopy-based diagnostics to monitor parasite prevalence and enable post-treatment surveillance; however, molecular diagnostics are rapidly being developed due to increased sensitivity, particularly in low-STH-prevalence settings. The genetic diversity of helminths and its potential impact on molecular diagnostics remain unclear. Using low-coverage genome sequencing, we assess the genetics of STHs within worm, faecal, and purified egg samples from 27 countries, identifying differences in the genetic connectivity and diversity of STH-positive samples across regions and cryptic diversity between closely related human- and pig-infective species. We …

Oscillatory Flow Improves Hydrodynamic Ordering Of Soft Suspensions In Rectangular Channels, Paul C. Millett

Mechanical Engineering Faculty Publications and Presentations

A computational study is presented that examines the hydrodynamic ordering of soft-particle suspensions within rectangular channels undergoing both steady and oscillatory flow. In these conditions, particles assemble into one-dimensional train-like configurations aligned in the flow direction. The results indicate that oscillatory flow facilitates a significant improvement in the ordering process, particularly for the assembly of multiple side-by-side trains within the channel. Several key parameters are systematically varied, including the Wolmersley number (Wo) representing the oscillatory frequency, the capillary number (Ca) representing the particle deformability, and the particle volume fraction (phi). It is found that optimal ordering occurs for a particular …

Integrase-Deficient Lentiviral Vector As A Platform For Efficient Crispr/Cas9-Mediated Gene Editing For Mucopolysaccharidosis Iva, Fnu Nidhi, Shunji Tomatsu

Department of Pediatrics Faculty Papers

Mucopolysaccharidosis IVA (MPS IVA) is a lysosomal storage disorder causing systemic skeletal dysplasia due to a deficiency of N-acetyl-galactosamine-6-sulfate sulfatase (GALNS) enzyme activity, leading to the impaired degradation and accumulation of glycosaminoglycans (GAGs), keratan sulfate (KS) and chondroitin-6-sulfate. While treatments such as enzyme replacement therapy (ERT) and hematopoietic stem cell transplantation (HSCT) are available, they have significant limitations regarding efficacy in skeletal tissues and long-term safety, highlighting the need for more effective therapies. We evaluated a novel gene therapy approach using a dual Integrase-deficient lentiviral vector (IDLV) to deliver an expression cassette that includes human GALNS cDNA and Cas9 sgRNA, …

Incontinentia pigmenti (IP) is caused by loss-of-function variants in IKBKG, with molecular genetic diagnosis complicated by a pseudogene. We describe seven individuals from three families with IP but negative clinical genetic testing in whom long-read sequencing identified causal variants, including one family with the common exon 4-10 deletion not identified by conventional clinical genetic testing. Concurrent methylation analysis explained disease severity in one individual who died from neurologic complications, identified a mosaic variant in an individual with an atypical presentation, and confirmed skewed X chromosome inactivation in an XXY individual.

The CREBBP lysine acetyltransferase (KAT) is frequently mutated in follicular lymphoma and diffuse large B-cell lymphoma and has been studied using gene knockout in murine and human cells. However, most CREBBP mutations encode amino acid substitutions within the catalytic KAT domain (CREBBP KAT-PM) that retain an inactive protein and have not been extensively characterized. Using CRISPR gene editing and extensive epigenomic characterization of lymphoma cell lines, we found that CREBBP KAT-PM lead to unloading of CREBBP from chromatin, loss of enhancer acetylation, and prevention of EP300 compensation. These enhancers were enriched for those that are dynamically loaded by CREBBP in …
