Spatial molecular profiling has provided biomedical researchers valuable opportunities to better understand the relationship between cellular localization and tissue function. Effectively modeling multi-modal spatial omics data is crucial for understanding tissue complexity and underlying biology. Furthermore, improvements in spatial resolution have led to the advent of technologies that can generate spatial molecular data with sub-cellular resolution, requiring the development of computationally efficient methods that can handle the resulting large-scale datasets. MISO (MultI-modal Spatial Omics) is a versatile algorithm for feature extraction and clustering, capable of integrating multiple modalities from diverse spatial omics experiments with high spatial resolution. Its effectiveness is …

Modern advances in systemic and localized therapies for patients with renal cell carcinoma (RCC) have significantly improved patients' outcomes. If disease progression occurs after initial treatment, clinicians often have multiple options for a first salvage therapy. Because salvage and initial treatments both may affect overall survival time, and they may interact in unanticipated ways, there is a growing need to determine sequences of initial therapy and first salvage therapy that maximize overall survival while maintaining quality of life. The complexity of this problem grows if a second salvage therapy must be chosen for patients with treatment-resistant disease or a second …

Faculty, Staff and Student Publications

Background: Adult-type granulosa cell tumors (AGCTs) are rare ovarian sex cord/stromal tumors with near-universal hotspot mutations in FOXL2 (c.C402G; p.Cys134Trp). Progress in the treatment of relapsed AGCT has been hindered by the lack of high-fidelity FOXL2-based mouse models. To address this critical unmet need, we created and validated a genetically engineered inducible mouse model of the human FOXL2 mutation that recapitulates the key features of the human disease.

Methods: Gene targeting in embryonic stem cells was used to introduce a Cre-inducible Foxl2C130W allele (mouse equivalent of the human oncogenic mutation) into the endogenous mouse Foxl2 locus. Animals with the Foxl2C130W-FLEx …

Several reports have demonstrated that CD147, an N-glycosylated protein that is exchanged by cells in soluble form or through small extracellular vesicles (sEVs), can promote cancer progression. However, its activity related to EVs in colorectal cancer (CRC) is still not fully understood. Previously, we showed that sEV secretion during CRC stem cell (CR-CSCs) differentiation is partially controlled by CD147, and that CD147-expressing sEVs (sEVs-CD147) activate a signalling cascade in recipient cells, inducing molecular invasive features in CR-CSCs. In the present study, we demonstrated that sEVs-CD147 increase the expression of myofibroblast and activation markers in cancer-associated fibroblasts (CAF). In sEVs-CD147-activated CAF, …

Genomes are blueprints of life essential for an organism's survival, propagation, and evolutionary adaptation. Eukaryotic genomes comprise of DNA, core histones, and several other nonhistone proteins, packaged into chromatin in the tiny confines of nucleus. Chromatin structural organization restricts transcription factors to access DNA, permitting binding only after specific chromatin remodeling events. The fundamental processes in living cells, including transcription, replication, repair, and recombination, are thus regulated by chromatin structure through ATP-dependent remodeling, histone variant incorporation, and various covalent histone modifications including phosphorylation, acetylation, and ubiquitination. These modifications, particularly involving histone variant H2AX, furthermore play crucial roles in DNA damage …

Reducing Igg Accumulation Via Neonatal Fc Receptor (Fcrn) Blockade Relieves Neuropathic Pain, Nathan T Fiore, Kendal F Willcox, Dorsa Dayani, Younus A Zuberi, Cobi J Heijnen, Peter M Grace

Faculty, Staff and Student Publications

Preclinical and clinical studies have established that autoreactive immunoglobulin G (IgG) can drive neuropathic pain. We recently demonstrated that sciatic nerve chronic constriction injury (CCI) in male and female mice results in the production of pronociceptive IgG, which accumulates around the lumbar region, including within the dorsal root ganglia (DRG) and spinal cord, facilitating the development of neuropathic pain. These data raise the intriguing possibility that neuropathic pain may be alleviated by reducing the accumulation of IgG. To this end, we tested whether biologic inhibition or genetic deletion of the neonatal Fc receptor (FcRn) would attenuate mechanical hypersensitivity (allodynia) and …

Clinical Use Of Gafchromic Ebt4 Film For In Vivo Dosimetry For Total Body Irradiation, Emily Draeger, Fada Guan, Min-Young Lee, Dae Yup Han, William Donahue, Zhe Jay Chen

Faculty, Staff and Student Publications

Purpose: In vivo dosimetry is a common requirement to validate dose accuracy/uniformity in total body irradiation (TBI). Several detectors can be used for in vivo dosimetry, including thermoluminescent dosimeters (TLDs), diodes, ion chambers, optically stimulated luminescent dosimeters (OSLDs), and film. TLDs are well established for use in vivo but required expertise and clinical system availability may make them impractical for multifractionated TBI. OSLDs offer quick readout, but recalls have restricted their use. The purpose of this work was to validate the newly available Gafchromic EBT4 film for TBI in vivo dosimetry.

Methods: Film calibration curves were created under standard conditions …

Despite extensive research into the genetic underpinnings of neurodevelopmental disorders (NDD), many clinical cases remain unresolved. We studied a female proband with a NDD, mildly dysmorphic facial features, and brain stem hypoplasia on neuroimaging. Comprehensive genomic analyses revealed a terminal 5p loss and a terminal 18q gain in the proband while a diploid copy number for chromosomes 5 and 18 in both parents. Genomic investigations in the proband identified an unbalanced translocation t(5;18) with additional genetic material from chromosome 2 (2q31.3) inserted at the breakpoint, pointing to a complex chromosomal rearrangement (CCR) involving 5p15.2, 2q31.3, and 18q21.32.

Tandem repeats (TRs) are highly polymorphic in the human genome, have thousands of associated molecular traits and are linked to over 60 disease phenotypes. However, they are often excluded from at-scale studies because of challenges with variant calling and representation, as well as a lack of a genome-wide standard. Here, to promote the development of TR methods, we created a catalog of TR regions and explored TR properties across 86 haplotype-resolved long-read human assemblies. We curated variants from the Genome in a Bottle (GIAB) HG002 individual to create a TR dataset to benchmark existing and future TR analysis methods. We …
