A Representative Clinical Course Of Progression, With Molecular Insights, Of Hormone Receptor-Positive, Her2-Negative Bone Metastatic Breast Cancer, Elizabeth Magno, Karen M. Bussard

Department of Pharmacology, Physiology, and Cancer Biology Faculty Papers

Despite treatment advances, breast cancer remains a leading cause of death of women in the United States, mostly due to metastatic disease. Bone is a preferential site for breast cancer metastasis, and most metastatic breast cancer patients experience bone involvement at the time of death. The majority of patients with bone metastatic breast cancer are first diagnosed with and treated for early-stage disease, and from development of early-stage breast cancer to the recurrence of cancer in the bones, up to 30 years may elapse. Throughout this timeframe, a typical patient undergoes many treatments that have effects on the bone microenvironment. …

BACKGROUND

COVID-19 convalescent plasma (CCP) virus-specific antibody levels that translate into recipient posttransfusion antibody levels sufficient to prevent disease progression are not defined.

METHODS

This secondary analysis correlated donor and recipient antibody levels to hospitalization risk among unvaccinated, seronegative CCP recipients within the outpatient, double-blind, randomized clinical trial that compared CCP to control plasma. The majority of COVID-19 CCP arm hospitalizations (15/17, 88%) occurred in this unvaccinated, seronegative subgroup. A functional cutoff to delineate recipient high versus low posttransfusion antibody levels was established by 2 methods: (i) analyzing virus neutralization–equivalent anti–Spike receptor-binding domain immunoglobulin G (anti-S-RBD IgG) responses in donors …

Gestational Testosterone Excess Early To Mid-Pregnancy Disrupts Maternal Lipid Homeostasis And Activates Biosynthesis Of Phosphoinositides And Phosphatidylethanolamines In Sheep, Nadia Saadat, Brooke Pallas, Joseph Ciarelli, Arpita Kalla Vyas, Vasantha Padmanabhan

2020-Current year OA Pubs

Gestational hyperandrogenism is a risk factor for adverse maternal and offspring outcomes with effects likely mediated in part via disruptions in maternal lipid homeostasis. Using a translationally relevant sheep model of gestational testosterone (T) excess that manifests maternal hyperinsulinemia, intrauterine growth restriction (IUGR), and adverse offspring cardiometabolic outcomes, we tested if gestational T excess disrupts maternal lipidome. Dimensionality reduction models following shotgun lipidomics of gestational day 127.1 ± 5.3 (term 147 days) plasma revealed clear differences between control and T-treated sheep. Lipid signatures of gestational T-treated sheep included higher phosphoinositides (PI 36:2, 39:4) and lower acylcarnitines (CAR 16:0, 18:0, 18:1), …

Chimeric Oncolytic Adenovirus Evades Neutralizing Antibodies From Human Patients And Exhibits Enhanced Anti-Glioma Efficacy In Immunized Mice, Dong Ho Shin, Hong Jiang, Andrew G Gillard, Debora Kim, Xuejun Fan, Sanjay K Singh, Teresa T Nguyen, Sagar S Sohoni, Andres R Lopez-Rivas, Akhila Parthasarathy, Chibawanye I Ene, Joy Gumin, Frederick F Lang, Marta M Alonso, Candelaria Gomez-Manzano, Juan Fueyo

Faculty, Staff and Student Publications

Oncolytic viruses are a promising treatment for patients with high-grade gliomas, but neutralizing antibodies can limit their efficacy in patients with prior virus exposure or upon repeated virus injections. Data from a previous clinical trial using the oncolytic adenovirus Delta-24-RGD showed that generation of anti-viral neutralizing antibodies may affect the long-term survival of glioma patients. Past studies have examined the effects of neutralizing antibodies during systemic virus injections, but largely overlooked their impact during local virus injections into the brain. We found that immunoglobulins colocalized with viral proteins upon local oncolytic virotherapy of brain tumors, warranting a strategy to prevent …

Faculty, Staff and Student Publications

Background: The combination of radiotherapy and immunotherapy (immunoradiotherapy) has been increasingly used for treating a wide range of cancers. However, some tumors are resistant to immunoradiotherapy. We have previously shown that MER proto-oncogene tyrosine kinase (MerTK) expressed on macrophages mediates resistance to immunoradiotherapy. We therefore sought to develop therapeutics that can mitigate the negative impact of MerTK. We designed and developed a MerTK specific antisense oligonucleotide (ASO) and characterized its effects on eliciting an anti-tumor immune response in mice.

Caldendrin Is A Repressor Of Piezo2 Channels And Touch Sensation In Mice, Josue A Lopez, Luis O Romero, Wai-Lin Kaung, J Wesley Maddox, Valeria Vásquez, Amy Lee

Faculty, Staff and Student Publications

The sense of touch is crucial for cognitive, emotional, and social development and relies on mechanically activated (MA) ion channels that transduce force into an electrical signal. Despite advances in the molecular characterization of these channels, the physiological factors that control their activity are poorly understood. Here, we used behavioral assays, electrophysiological recordings, and various mouse strains (males and females analyzed separately) to investigate the role of the calmodulin-like Ca2+ sensor, caldendrin, as a key regulator of MA channels and their roles in touch sensation. In mice lacking caldendrin (Cabp1 KO), heightened responses to tactile stimuli correlate with enlarged …
