The data were collected from each teen's parents or guardians and health-care professionals. Weighted prevalence estimates were calculated, and multivariable regression analyses were conducted.

RESULTS: The prevalence of HPV vaccine initiation was 75.1% and of remaining up-to-date was …

Nanodiscs: A Novel Approach To The Study Of The Methionine Abc Transporter System, Michael T. Winslow

Master's Theses

Membrane transporter proteins play the vital role of moving compounds in and out of the cell and are essential for all living organisms. ATP Binding Cassette (ABC) family transporters function both as importers and exporters in prokaryotes. MetNI is an E. coli Type I ABC transporter responsible for the uptake of methionine into the cytosol from the cell periplasmic space through the cell membrane to maintain intracellular methionine pools. ABC transporters, like other membrane proteins, are most often mechanistically and structurally studied in vitro, solubilized by detergents. However, detergent micelles may affect the conformational changes of membrane proteins relative to …

A Single Dominant Locus Restricts Retrovirus Replication In Ybr/Ei Mice, Helen A Beilinson, Amanda Sevilleja, Jessica Spring, Fernando Benavides, Vera Beilinson, Nickolas Neokosmidis, Tatyana Golovkina

Faculty, Staff and Student Publications

Differential responses to viral infections are influenced by the genetic makeup of the host. Studies of resistance to retroviruses in human populations are complicated due to the inability to conduct proof-of-principle studies. Inbred mouse lines, which have a range of susceptible phenotypes to retroviruses, are an ideal tool to identify and characterize mechanisms of resistance and define their genetic underpinnings. YBR/Ei mice become infected with Mouse Mammary Tumor Virus, a mucosally transmitted murine retrovirus, but eliminate the virus from their pedigrees. Virus elimination correlates with a lack of virus-specific neonatal oral tolerance, which is a major mechanism for blocking the …

Crabr-Net: A Contextual Relational Attention-Based Recognition Network For Remote Sensing Scene Objective, Ningbo Guo, Mingyong Jiang, Lijing Gao, Yizhuo Tang, Jinwei Han, Xiangning Chen

Faculty, Staff and Student Publications

Remote sensing scene objective recognition (RSSOR) plays a serious application value in both military and civilian fields. Convolutional neural networks (CNNs) have greatly enhanced the improvement of intelligent objective recognition technology for remote sensing scenes, but most of the methods using CNN for high-resolution RSSOR either use only the feature map of the last layer or directly fuse the feature maps from various layers in the "summation" way, which not only ignores the favorable relationship information between adjacent layers but also leads to redundancy and loss of feature map, which hinders the improvement of recognition accuracy. In this study, a …

Persistence of leukemic stem cells (LSCs) is one of the determining factors to acute myeloid leukemia (AML) treatment failure and responsible for the poor prognosis of the disease. Hence, novel therapeutic strategies that target LSCs are crucial for treatment success. We investigated if targeting Bcl-2 and peroxisome proliferator activated receptor α (PPARα), two distinct cell survival regulating mechanisms could eliminate LSCs. This study demonstrate that the Bcl-2 inhibitor venetoclax combined with the PPARα agonist chiglitazar resulted in synergistic killing of LSC-like cell lines and CD34+ primary AML cells while sparing their normal counterparts. Furthermore, the combination regimen significantly suppressed AML …

An Evolutionarily Nascent Architecture Underlying The Formation And Emergence Of Biomolecular Condensates, Nima Jaberi-Lashkari, Byron Lee, Fardin Aryan, Eliezer Calo

Faculty, Staff and Student Publications

Biomolecular condensates are implicated in core cellular processes such as gene regulation and ribosome biogenesis. Although the architecture of biomolecular condensates is thought to rely on collective interactions between many components, it is unclear how the collective interactions required for their formation emerge during evolution. Here, we show that the structure and evolution of a recently emerged biomolecular condensate, the nucleolar fibrillar center (FC), is explained by a single self-assembling scaffold, TCOF1. TCOF1 is necessary to form the FC, and it structurally defines the FC through self-assembly mediated by homotypic interactions of serine/glutamate-rich low-complexity regions (LCRs). Finally, introduction of TCOF1 …

We further applied C-statistic and decision curve analysis …

Endometrial Fluid Biomarkers And Their Potential As Predictors Of Successful Embryo Implantation, Ana Rita Alves, Margarida Figueiredo Dias, Margarida Silvestre

BioMedicine

Background: Embryo implantation is a complex biological process which requires synchronized dialogue between the receptive endometrium and the blastocyst. The endometrium, however, is only receptive to embryo implantation for a very short period. Recurrent implantation failure (RIF) is a major challenge in assisted reproductive techniques mainly due to impaired receptivity, but there is still a need for a reliable and valid clinical test to assess endometrial receptiveness, especially at embryo transfer time. The aim of this review is to investigate what is currently known about the contribution of endometrial fluid (EF) to endometrial receptivity by identifying its potential biomarkers. Methods: …

Sctiger: A Deep-Learning Method For Inferring Gene Regulatory Networks From Case Versus Control Scrna-Seq Datasets., Madison Dautle, Shaoqiang Zhang, Yong Chen

College of Science & Mathematics Departmental Research

Inferring gene regulatory networks (GRNs) from single-cell RNA-seq (scRNA-seq) data is an important computational question to find regulatory mechanisms involved in fundamental cellular processes. Although many computational methods have been designed to predict GRNs from scRNA-seq data, they usually have high false positive rates and none infer GRNs by directly using the paired datasets of case-versus-control experiments. Here we present a novel deep-learning-based method, named scTIGER, for GRN detection by using the co-differential relationships of gene expression profiles in paired scRNA-seq datasets. scTIGER employs cell-type-based pseudotiming, an attention-based convolutional neural network method and permutation-based significance testing for inferring GRNs among …

The Histone Chaperone Function Of Daxx Is Dispensable For Embryonic Development, Chang Sun, Yuan Qi, Natalie Fowlkes, Nina Lazic, Xiaoping Su, Guillermina Lozano, Amanda R Wasylishen

Faculty, Staff and Student Publications

Daxx functions as a histone chaperone for the histone H3 variant, H3.3, and is essential for embryonic development. Daxx interacts with Atrx to form a protein complex that deposits H3.3 into heterochromatic regions of the genome, including centromeres, telomeres, and repeat loci. To advance our understanding of histone chaperone activity in vivo, we developed two Daxx mutant alleles in the mouse germline, which abolish the interactions between Daxx and Atrx (DaxxY130A), and Daxx and H3.3 (DaxxS226A). We found that the interaction between Daxx and Atrx is dispensable for viability; mice are born at the …

Prenylated Stilbenoids As Paclitaxel Adjuvants In Triple-Negative Breast Cancer Treatment, Sepideh Mohammadhosseinpour

Student Theses and Dissertations

Triple-negative breast cancer (TNBC), the most fatal breast cancer subtype, lacks three main receptors (the human epidermal growth factor 2 receptor (ERBB2, formerly HER2), estrogen (ER) and progesterone (PR) receptors) and represents about 15% of all breast tumors. The most common treatment for TNBC is chemotherapy, being paclitaxel one of the most prescribed drugs. One of the main issues of paclitaxel is its high level of toxicity to non-cancerous cells and the development of paclitaxel resistance in the TNBC cells. Adjuvant therapy has been proposed as an alternative approach to increase the efficacy of a drug or circumvent drug resistance. …

Targeting Breast Cancer: The Familiar, The Emerging, And The Uncharted Territories, Hamidreza Montazeri Aliabadi, Arthur Manda, Riya Sidgal, Co Chung

Pharmacy Faculty Articles and Research

Breast cancer became the most diagnosed cancer in the world in 2020. Chemotherapy is still the leading clinical strategy in breast cancer treatment, followed by hormone therapy (mostly used in hormone receptor-positive types). However, with our ever-expanding knowledge of signaling pathways in cancer biology, new molecular targets are identified for potential novel molecularly targeted drugs in breast cancer treatment. While this has resulted in the approval of a few molecularly targeted drugs by the FDA (including drugs targeting immune checkpoints), a wide array of signaling pathways seem to be still underexplored. Also, while combinatorial treatments have become common practice in …

Immunotherapy Targeting Different Immune Compartments In Combination With Radiation Therapy Induces Regression Of Resistant Tumors, Nils-Petter Rudqvist, Maud Charpentier, Claire Lhuillier, Erik Wennerberg, Sheila Spada, Caroline Sheridan, Xi Kathy Zhou, Tuo Zhang, Silvia C Formenti, Jennifer S Sims, Alicia Alonso, Sandra Demaria

Faculty, Staff and Student Publications

Radiation therapy (RT) increases tumor response to CTLA-4 inhibition (CTLA4i) in mice and in some patients, yet deep responses are rare. To identify rational combinations of immunotherapy to improve responses we use models of triple negative breast cancer highly resistant to immunotherapy in female mice. We find that CTLA4i promotes the expansion of CD4+ T helper cells, whereas RT enhances T cell clonality and enriches for CD8+ T cells with an exhausted phenotype. Combination therapy decreases regulatory CD4+ T cells and increases effector memory, early activation and precursor exhausted CD8+ T cells. A combined gene signature comprising these three CD8+ …
