BACKGROUND: The intestine occupies the critical interface between cholesterol absorption and excretion. Surprisingly little is known about the role of de novo cholesterol synthesis in this organ, and its relationship to whole body cholesterol homeostasis. Here, we investigate the physiological importance of this pathway through genetic deletion of the rate-limiting enzyme.

METHODS: Mice lacking 3-hydroxy-3-methylglutaryl-coenzyme A reductase (Hmgcr) in intestinal villus and crypt epithelial cells were generated using a Villin-Cre transgene. Plasma lipids, intestinal morphology, mevalonate pathway metabolites, and gene expression were analyzed.

RESULTS: Mice with intestine-specific loss of Hmgcr were markedly smaller at birth, but gain …

Ovarian cancer is the deadliest gynecologic cancer, and novel therapeutic options are crucial to improve overall survival. Here we provide evidence that impairment of oxidative phosphorylation (OXPHOS) can help control ovarian cancer progression, and this benefit correlates with expression of the two mitochondrial master regulators PGC1α and PGC1β. In orthotopic patient-derived ovarian cancer xenografts (OC-PDX), concomitant high expression of PGC1α and PGC1β (PGC1α/β) fostered a unique transcriptional signature, leading to increased mitochondrial abundance, enhanced tricarboxylic acid cycling, and elevated cellular respiration that ultimately conferred vulnerability to OXPHOS inhibition. Treatment with the respiratory chain complex I inhibitor IACS-010759 caused mitochondrial swelling …

Development And Management Of Depression During And After Pregnancy, Alexa Bouts, Maria Patnella, Jourdan Ujlaki, Emily Wells, Hannah Lamb, Michelle Musser

Pharmacy and Wellness Review

Depression during pregnancy is common, whether it is a new onset of the disease or emerging symptoms of the already existent disease. Due to patient and prescriber concerns with antidepressant use during pregnancy, approximately three-quarters of those diagnosed with depression remain untreated. Furthermore, up to half of pregnant women with depression remain undiagnosed due to lack of recognition. As a result, both mother and fetus are at risk for negative health outcomes including substance abuse, functional impairment, increased risk of postnatal depression and poor pregnancy outcomes. Benefits must be balanced against the risks when considering pharmacologic treatment options to manage …

Adherence Enables Neisseria Gonorrhoeae To Overcome Zinc Limitation Imposed By Nutritional Immunity Proteins, Jocelyn C Ray, Asya Smirnov, Stavros A Maurakis, Simone A Harrison, Eugene Ke, Walter J Chazin, Cynthia Nau Cornelissen, Alison K Criss

Open Access Publications

Neisseria gonorrhoeae (Gc) must overcome the limitation of metals such as zinc to colonize mucosal surfaces in its obligate human host. While the zinc-binding nutritional immunity proteins calprotectin (S100A8/A9) and psoriasin (S100A7) are abundant in human cervicovaginal lavage fluid, Gc possesses TonB-dependent transporters TdfH and TdfJ that bind and extract zinc from the human version of these proteins, respectively. Here we investigated the contribution of zinc acquisition to Gc infection of epithelial cells of the female genital tract. We found that TdfH and TdfJ were dispensable for survival of strain FA1090 Gc that was associated with Ect1 human immortalized epithelial …

Open Access Publications

Mycosis fungoides (MF), the most common cutaneous T-cell lymphoma, classically has an indolent clinical course, with lesions slowly progressing from patch to plaque to tumor stage. In some cases, the late stages of disease involve extra-cutaneous dissemination to lymph nodes or viscera. Although this "Alibert-Bazin" type is the prototypic MF, there are several variants and subtypes of MF that may have different clinical implications for treatment and prognosis. We describe a woman whose disease course involved a variety of histopathologic and immunophenotypic variants including folliculotropic MF, granulomatous MF with loss of CD8, and then finally CD4/CD8 double-negative MF with large …

Metronidazole Treatment Rapidly Reduces Genital Inflammation Through Effects On Bacterial Vaginosis-Associated Bacteria Rather Than Lactobacilli, Eric Armstrong, Hilary Reno, Et Al.

2020-Current year OA Pubs

BackgroundBacterial vaginosis (BV) causes genital inflammation and increases HIV risk, whereas a vaginal microbiota dominated by Lactobacillus species is associated with immune quiescence and relative HIV protection. BV treatment reduces genital inflammation, but it is unclear whether this reduction is driven by a decrease in BV-associated bacteria or an increase in Lactobacillus species.METHODSTo evaluate the short-term effect of standard BV treatment on genital immunology and the vaginal microbiota, vaginal swabs were collected immediately before and after metronidazole treatment for BV and analyzed with multiplex ELISA, metagenomic sequencing, and quantitative PCR.RESULTSTopical metronidazole treatment rapidly reduced vaginal levels of proinflammatory cytokines, chemokines, …

The Targeted Smac Mimetic Sw Iv-134 Augments Platinum-Based Chemotherapy In Pre-Clinical Models Of Ovarian Cancer, Pratibha S Binder, Yassar M Hashim, James Cripe, Tommy Buchanan, Abigail Zamorano, Suwanna Vangveravong, David G Mutch, William G Hawkins, Matthew A Powell, Dirk Spitzer

2020-Current year OA Pubs

BACKGROUND: Ovarian cancer is initially responsive to frontline chemotherapy. Unfortunately, it often recurs and becomes resistant to available therapies and the survival rate for advanced and recurrent ovarian cancer is unacceptably low. We thus hypothesized that it would be possible to achieve more durable treatment responses by combining cisplatin chemotherapy with SW IV-134, a cancer-targeted peptide mimetic and inducer of cell death. SW IV-134 is a recently developed small molecule conjugate linking a sigma-2 ligand with a peptide analog (mimetic) of the intrinsic death pathway activator SMAC (second-mitochondria activator of caspases). The sigma-2 receptor is overexpressed in ovarian cancer and …

Chromosomal Imbalances Detected Via Rna-Sequencing In 28 Cancers, Zuhal Ozcan, Francis A San Lucas, Justin W Wong, Kyle Chang, Konrad H Stopsack, Yasminka A Jakubek

Faculty, Staff and Student Publications

Motivation: RNA-sequencing (RNA-seq) of tumor tissue is typically only used to measure gene expression. Here, we present a statistical approach that leverages existing RNA-seq data to also detect somatic copy number alterations (SCNAs), a pervasive phenomenon in human cancers, without a need to sequence the corresponding DNA.

Results: We present an analysis of 4942 participant samples from 28 cancers in The Cancer Genome Atlas (TCGA), demonstrating robust detection of SCNAs from RNA-seq. Using genotype imputation and haplotype information, our RNA-based method had a median sensitivity of 85% to detect SCNAs defined by DNA analysis, at high specificity (∼95%). As an …

Pharmacological Chaperones For The Oxytocin Receptor Increase Oxytocin Responsiveness In Myometrial Cells, Manasi Malik, Yingye Fang, Monali Wakle-Prabagaran, Michelle Roh, Kevin Prifti, Antonina I Frolova, Princess I Imoukhuede, Sarah K England

2020-Current year OA Pubs

Oxytocin is a potent uterotonic agent administered to nearly all patients during childbirth in the United States. Inadequate oxytocin response can necessitate Cesarean delivery or lead to uterine atony and postpartum hemorrhage. Thus, it may be clinically useful to identify patients at risk for poor oxytocin response and develop strategies to sensitize the uterus to oxytocin. Previously, we showed that the V281M variant in the oxytocin receptor (OXTR) gene impairs OXTR trafficking to the cell surface, leading to a decreased oxytocin response in cells. Here, we sought to identify pharmacological chaperones that increased oxytocin response in cells expressing WT or …
