Mutation of KRAS in endothelial cells (KRAS-EC) leads to intracerebral hemorrhage (ICH) in brain arteriovenous malformations (bAVM), resulting in severe disabilities or even death. However, it is unclear what causes this hemorrhagic conversion of bAVM. Here, using a locally established, clinically-relevant sporadic bAVM mouse model, created by overexpressing mutant KRAS (KRASG12V) in the brain EC, we demonstrate that KRAS-EC act as trigger for microglia (MG) activation and infiltration of macrophages (Mϕ). Using three-dimensional immunostaining approach with cleared human and mouse bAVM tissues, we demonstrate an abundance of MG/Mϕ around the bAVM nidus. The presence of MG/Mϕ are correlated to the …

ASTN1 encodes astrotactin 1, a neuronal-glial ligand in the developing brain that promotes neuronal migration along radial glia in brain structures with laminar organization, such as the cerebral cortex, hippocampus, and cerebellum. In mouse models, disruption of Astn1 results in neuronal migration deficits, a mild reduction in cerebellar volume, and balance and coordination deficits. In humans, bi-allelic ASTN1 variants have been identified in nine individuals with neurodevelopmental disorders (NDDs) with or without brain malformations. ASTN1 additionally interacts with astrotactin 2 (ASTN2) to implement neuronal migration; ASTN2 deletions associate with NDDs with reduced penetrance. Here, we describe eighteen individuals with NDDs …

Predicting The Prognosis Of Primary And Substance-Associated Psychoses Using Urine Drug Screens: A 5-Year Retrospective Longitudinal Study Using Medical Records, Erich J. Aschenbrenner, Andrew C. Voluse

Psychiatry Publications

Substance use is frequently implicated in psychosis. However, the prognostic assumptions guiding differential treatment decisions between substance-induced and primary/affective psychoses have received inconsistent support. Substance-induced psychosis research has often been limited by aggregating substances or using diagnosis as both a grouping variable and an outcome (i.e., diagnostic conversion). The current study examined medical records for 1379 patients for 5 years following their first presentation with psychosis after January 2013 to a regional medical center. Clinically relevant outcomes were compared across groups defined by the substances detected in patients' urine at their initial presentation. Initial drug screen results predicted the initial …

Faculty, Staff and Student Publications

To understand the relative importance of cis and trans effects on regulation, we crossed multi-parent recombinant-inbred lines (RILs) to a common tester and measured allele-specific gene expression in the offspring. Testing the difference of allelic imbalance between two RIL × Tester crosses is a test of cis or trans, depending on the RIL alleles compared. The study design also enables to separation of two sources of trans variation, genetic and environmental, detected via interactions with cis effects. We demonstrate the effectiveness of this approach in a long-read RNA-seq experiment in female abdominal tissue at two time points in Drosophila melanogaster. …

Dysregulated ribosome biogenesis and p53 mutations are known to play oncogenic roles in various cancers, including pancreatic cancer. In this study, we demonstrated the therapeutic potential of BMH-21, a pharmacologic inhibitor of RNA polymerase I, against pancreatic cancer by uncovering a novel molecular mechanism involving RPA194-mediated ubiquitination of mutant p53 without affecting the ubiquitination of wild-type p53. Our key findings are that (i) BMH-21 selectively induces apoptosis and cell growth inhibition of pancreatic cancer cells with no effect on normal human pancreatic ductal epithelial cells; (ii) BMH-21 degrades RPA194; (iii) BMH-21 inhibits recruitment of both RPA194 and RPA135 on rDNA …

Radiation therapy is integral to the treatment regimens of over 50% of cancer patients. However, it is not biologically targeted to just the tumor, leading to adverse effects in peritumoral normal tissue. Selective uptake of gold nanoparticles (AuNPs) by tumors realizes tumor-specific radiosensitization via increased secondary electron release from high atomic number gold atoms. Here, we review AuNP-mediated radiosensitization and outline strategies to optimize tumor-targeted AuNP delivery. Modifying the physicochemical characteristics of AuNPs, including size, shape, charge, and surface chemistry, can increase their ability to evade the reticuloendothelial system (RES) and penetrate the dense tumor stromal architecture, thereby promoting tumor …
