Modern-Day Neanderthal Genetic Lifewriting, Interspecies Romance, And The Promise Of Multispecies Autoethnography, Travis Brisini

Faculty Publications

Advances in contemporary genetic science have reshaped the narratives whereby individuals and communities make sense of their personal, family, and communal histories. In this process, unknown connections have been revealed and familiar orthodoxies disrupted. This essay examines the consequences of a particularly unusual revelation - the dawning awareness of the presence of nonhuman and archaic human DNA in human genetic lines - for efforts at writing about identity and society. In this autoethnographic account, I examine my own genetic inheritance of Neanderthal DNA, and posit a performative concept of genetic life writing that begins to unpack the complexities of this …

How To Do The History Of Sexual Science, Benjamin Kahan, Greta Lafleur Jan 2023

How To Do The History Of Sexual Science, Benjamin Kahan, Greta Lafleur

Faculty Publications

This introduction maps the ways in which sexual scientific thought circulated during the fin de siècle, tracing the interconnections between and breaks in the global circuits of sexological thought and how this circuitry continues to structure sexuality in the present. In so doing, Kahan and LaFleur position their approach and that of the special issue as a whole within the larger field of sexology, placing it in more robust dialogue with sexuality studies and attending in particular to sexology's racial and imperial logics. They examine the ways in which racial science and colonial knowledge constitute sexual science as an amorphous …

Redox Regulation In Diabetic Kidney Disease, Ilse S. Daehn, Ubong S. Ekperikpe, Krisztian Stadler

Division of Basic Science Faculty Publications

Diabetic kidney disease (DKD) is one of the most devastating complications of diabetes mellitus, where currently there is no cure available. Several important mechanisms contribute to the pathogenesis of this complication, with oxidative stress being one of the key factors. The past decades have seen a large number of publications with various aspects of this topic; however, the specific details of redox regulation in DKD are still unclear. This is partly because redox biology is very complex, coupled with a complex and heterogeneous organ with numerous cell types. Furthermore, often times terms such as “oxidative stress” or reactive oxygen species …

Acute Stressors Do Not Impair Short-Term Memory Or Attention In An Aged Mouse Model Of Amyloidosis, Giuliana M. Dimarco, Breanna N. Harris, Alena V. Savonenko, Paul L. Soto Jan 2023

Acute Stressors Do Not Impair Short-Term Memory Or Attention In An Aged Mouse Model Of Amyloidosis, Giuliana M. Dimarco, Breanna N. Harris, Alena V. Savonenko, Paul L. Soto

Faculty Publications

Memory impairment in Alzheimer’s disease patients is thought to be associated with the accumulation of amyloid-beta peptides and tau proteins. However, inconsistent reports of cognitive deficits in pre-clinical studies have raised questions about the link between amyloid-beta and cognitive decline. One possible explanation may be that studies reporting memory deficits often involve behavioral assessments that entail a high stress component. In contrast, in tasks without a high stress component transgenic mice do not consistently show declines in memory. The glucocorticoid cascade hypothesis of aging and the vicious cycle of stress framework suggest that stress exacerbates dementia progression by initiating a …

Rbp4-Gal4, A Germline Driver That Activates In Meiosis, Reveals Functions For Vcp In Spermatid Development, Tyler J. Butsch, Alyssa E. Johnson, K. Adam Bohnert Jan 2023

Rbp4-Gal4, A Germline Driver That Activates In Meiosis, Reveals Functions For Vcp In Spermatid Development, Tyler J. Butsch, Alyssa E. Johnson, K. Adam Bohnert

Faculty Publications

Valosin-containing protein (VCP) is a versatile and ubiquitously expressed AAA+ ATPase that regulates multiple stages of Drosophila spermatogenesis. While VCP has documented roles in mitotic spermatogonia and meiotic spermatocytes, it is also highly expressed in post-meiotic spermatids, suggesting potential late-stage developmental functions as well. However, tools to assess late-stage activities of pleiotropic spermatogenesis genes such as VCP are lacking. Available germline-specific Gal4 drivers activate in stem cells or spermatogonia; consequently, knocking down VCP using one of these drivers disrupts or blocks early germ-cell development, precluding analysis of VCP in later stages. A Gal4 driver that activates later in development, such …

Introduction: Educational attainment, widely used in epidemiologic studies as a surrogate for socioeconomic status, is a predictor of cardiovascular health outcomes. Methods: A two-stage genome-wide meta-analysis of low-density lipoprotein cholesterol (LDL), high-density lipoprotein cholesterol (HDL), and triglyceride (TG) levels was performed while accounting for gene-educational attainment interactions in up to 226,315 individuals from five population groups. We considered two educational attainment variables: “Some College” (yes/no, for any education beyond high school) and “Graduated College” (yes/no, for completing a 4-year college degree). Genome-wide significant (p < 5 × 10−8) and suggestive (p < 1 × 10−6) variants were identified in Stage 1 (in up to 108,784 individuals) through genome-wide analysis, and those variants were followed up in Stage 2 studies (in up to 117,531 individuals). Results: In combined analysis of Stages 1 and 2, we identified 18 novel lipid loci (nine for LDL, seven for HDL, and two for TG) by two degree-of-freedom (2 DF) joint tests of main and interaction effects. Four loci showed significant interaction with educational attainment. Two loci were significant only in cross-population analyses. Several loci include genes with known or suggested roles in adipose (FOXP1, MBOAT4, SKP2, STIM1, STX4), brain (BRI3, FILIP1, FOXP1, LINC00290, LMTK2, MBOAT4, MYO6, SENP6, SRGAP3, STIM1, TMEM167A, TMEM30A), and liver (BRI3, FOXP1) biology, highlighting the potential importance of brain-adipose-liver communication in the regulation of lipid metabolism. An investigation of the potential druggability of genes in identified loci resulted in five gene targets shown to interact with drugs approved by the Food and Drug Administration, including genes with roles in adipose and brain tissue. Discussion: Genome-wide interaction analysis of educational attainment identified novel lipid loci not previously detected by analyses limited to main genetic effects.

Biochemical Alterations In The Follicular Fluid Of Bovine Peri-Ovulatory Follicles And Their Association With Final Oocyte Maturation, Noof Abdulrahman Alrabiah, Constantine A. Simintiras, Alexander C.O. Evans, Patrick Lonergan, Trudee Fair

Faculty Publications

Follicular fluid (FF), a product of vascular transudate and granulosa and thecal cell secretions, is the milieu that has evolved to support oocyte growth and maturation which plays a central role in oocyte quality determination. Therefore, a suboptimal FF composition may be reflected in compromised oocyte progression through maturation, fertilization, or embryo development. To date, the composition of bovine FF remains understudied. To address this, we comprehensively characterized the metabolomic constituency of bovine FF in the period during which the oocyte undergoes meiotic maturation. More specifically, FF from pre (-24 h) and peri (-2 h)-ovulatory follicles was profiled by high-throughput …

Comprehensive Meta-Analysis Of Qtl And Gene Expression Studies Identify Candidate Genes Associated With Aspergillus Flavus Resistance In Maize, Niranjan Baisakh, Eduardo A. Da Silva, Anjan K. Pradhan, Kanniah Rajasekaran

Faculty Publications

Aflatoxin (AF) contamination, caused by Aspergillus flavus, compromises the food safety and marketability of commodities, such as maize, cotton, peanuts, and tree nuts. Multigenic inheritance of AF resistance impedes conventional introgression of resistance traits into high-yielding commercial maize varieties. Several AF resistance-associated quantitative trait loci (QTLs) and markers have been reported from multiple biparental mapping and genome-wide association studies (GWAS) in maize. However, QTLs with large confidence intervals (CI) explaining inconsistent phenotypic variance limit their use in marker-assisted selection. Meta-analysis of published QTLs can identify significant meta-QTLs (MQTLs) with a narrower CI for reliable identification of genes and linked markers …

The human body is in daily contact with potentially toxic and infectious substances in the gastrointestinal tract (GIT). The GIT has the most significant load of antigens. The GIT can protect the intestinal integrity by allowing the passage of beneficial agents and blocking the path of harmful substances. Under normal conditions, a healthy intestinal barrier prevents toxic elements from entering the blood stream. However, factors such as stress, an unhealthy diet, excessive alcohol, antibiotics, and drug consumption can compromise the composition of the intestinal microbiota and the homeostasis of the intestinal barrier function of the intestine, leading to increased intestinal …
