Predicting Premature Birth Risk With Cfrna, Jason Lin, Jonathan Marin, John Santerre

SMU Data Science Review

Identifying which genes are early indicators for preterm births using cell-free ribonucleic acid (cfRNA) from non-invasive blood tests provided by pregnant women can improve prenatal care. Currently, there are no medical tests for early detection of preterm birth risk in routine checkups for pregnant women. Recent studies have shown potential genes that can predict preterm birth. Machine learning techniques are utilized to see if the Area Under the Curve (AUC) can be improved upon when evaluating the prediction accuracy for chosen genes sequences and concentrations. Using cell-free RNA data from non-invasive blood tests in conjunction with machine learning, we improve …


Evaluating The Therapeutic Efficacy Of Grb2 Inhibition In Ovarian Malignancies, Olivia Lara Aug 2019

Evaluating The Therapeutic Efficacy Of Grb2 Inhibition In Ovarian Malignancies, Olivia Lara

Dissertations and Theses (Open Access)

Purpose: Adaptor proteins such as growth factor receptor-bound protein-2 (Grb2) play important roles in cancer cell signaling. In the present study, we examined the biological effects of liposomal antisense oligodeoxynucleotide that blocks Grb2 expression (L-Grb2) in ovarian cancer models.

Experimental Design: Murine orthotopic models of ovarian cancer (OVCAR5 and SKOV3ip1) were used to study the biological effects of L-Grb2 on tumor growth. In vitro experiments (cell viability assay, Western blot analysis, siRNA transfection, and reverse phase protein array) were carried out to elucidate the mechanism and potential predictors of tumor response to L-Grb2.

Results: Treatment with L-Grb2 decreased tumor growth …

Recent evidence supports involvement of amylin and the amylin receptor in the pathogenesis of Alzheimer’s disease (AD). We have previously shown that amylin receptor antagonist, AC253, improves spatial memory in AD mouse models. Herein, we generated and screened a peptide library and identified two short sequence amylin peptides (12–14 aa) that are proteolytically stable, brain penetrant when administered intraperitoneally, neuroprotective against Aβ toxicity and restore diminished levels of hippocampal long term potentiation in AD mice. Systemic administration of the peptides for five weeks in aged 5XFAD mice improved spatial memory, reduced amyloid plaque burden, and neuroinflammation. The common residue SQELHRLQTY …

Prostate cancer (PCa) is the most common malignancy in men and is the leading cause of cancer-related male mortality. A disulfide cyclic peptide ligand [CTVRTSADC] 1 has been previously found to target extra domain B of fibronectin (EDB-FN) in the extracellular matrix that can dierentiate aggressive PCa from benign prostatic hyperplasia. We synthesized and optimized the stability of ligand 1 by amide cyclization to obtain [KTVRTSADE] 8 using Fmoc/tBu solid-phase chemistry. Optimized targeting ligand 8 was found to be stable in phosphate buered saline (PBS, pH 6.5, 7.0, and 7.5) and under redox conditions, with a half-life longer than 8 …

Investigating The Therapeutic Potential Of Targeting Lrrc15 In Endometrial Cancer, Christopher Pathoulas

All College Thesis Program, 2016-2019

Endometrial cancer is the most common gynecological malignancy and accounts for 6% of all cancers in women. In 2018, there were an estimated 63,280 new cases of endometrial cancer resulting in 11,350 deaths. In advanced stages, aggressive forms of endometrial cancer are able to invade the peritoneum and metastasize to the omentum and bowel. Shridhar et al. have identified leucine rich repeat containing 15 (LRRC15), a protein involved in cell adhesion and interactions with the extracellular matrix (ECM), as a potential therapeutic target due to its significantly higher expression in ovarian cancer tumors that have metastasized to the omentum and …

The Effects Of Antenatal Betamethasone On Late Preterm Infants, Jennifer Hummel, Abigail Prest, Xinhua Chen

Rowan-Virtua Research Day

Administration of steroids to mothers expected to deliver in the late preterm period has previously been found to decrease neonatal respiratory morbidity. In this retrospective chart review, there were no significant differences between groups in the primary outcome of required respiratory support for the neonate, incidence of periventricular hemorrhage or neonatal death. However, this study found that their rate of hyperbilirubinemia, need for phototherapy, and NICU stays were longer than their counterparts whose mothers did not receive steroids or who only received one dose.These findings may provide support for future protocols directed to improve neonatal morbidity secondary to jaundice.

The Effect Of Omm On Opioid Users With Chronic Low Back Pain, Danielle Cooley, James Bailey, Deanna Janora, Catherine Fusco, Kishan Patel

Rowan-Virtua Research Day

In the United States, approximately 100 million adults are affected by chronic pain, which reduces their quality of life and productivity, while accounting for billions in health care costs and lost revenue. (1) Opioids are considered the gold standard in the pharmacological treatment for chronic pain conditions, and prescriptions for opiates/opioids increased by 400% from 1999 to 2010. (1,2) Although opioid treatment is warranted during postsurgical and active cancer pain, physicians still commonly overprescribe opioids, which has led to addiction, high deaths rates by overdose, and the spread of communicable diseases. (1)

Since chronic pain is sustained by noxious sensory …

The Pharmabiotic For Phenylketonuria: Development Of A Novel Therapeutic, Chloé Elizabeth Lebegue Apr 2019

The Pharmabiotic For Phenylketonuria: Development Of A Novel Therapeutic, Chloé Elizabeth Lebegue

Senior Theses

Phenylketonuria, now known as phenylalanine hydroxylase (PAH) deficiency, is a genetic disorder of metabolism affecting approximately one in every 15,000 infants born in the United States. Patients have nonfunctional PAH enzyme secondary to one or more genetic mutations. The enzyme deficit results in destructive supraphysiologic blood phenylalanine levels upon consumption of the essential dietary amino acid phenylalanine. Current standards of care mitigate signs and symptoms of the disorder, but do not approach a cure. The methods for creating a prototype pharmabiotic as an innovative treatment strategy for PAH deficiency are described herein.

DNA molecular cloning techniques were utilized to engineer …


The Role Of Thyroglobulin In Thyroid Hormonogenesis, Cintia E. Citterio, Héctor M. Targovnik, Peter Arvan Mar 2019

The Role Of Thyroglobulin In Thyroid Hormonogenesis, Cintia E. Citterio, Héctor M. Targovnik, Peter Arvan

Pharmacy Faculty Articles and Research

In humans, the thyroid hormones T3 and T4 are synthesized in the thyroid gland in a process that crucially involves the iodoglycoprotein thyroglobulin. The overall structure of thyroglobulin is conserved in all vertebrates. Upon thyroglobulin delivery from thyrocytes to the follicular lumen of the thyroid gland via the secretory pathway, multiple tyrosine residues can become iodinated to form mono-iodotyrosine (MIT) and/or di-iodotyrosine (DIT); however, selective tyrosine residues lead to preferential formation of T4 and T3 at distinct sites. T4 formation involves oxidative coupling between two DIT side chains, and de novo T3 formation involves …

Improving the utilization of pharmacologic agents in the pediatric population yields significant, perhaps life-long, benefits. Genetic factors related to the disposition of a medication or an alteration at the target receptor site contributes to the observed variability of exposure and response between individuals. An additional source of this variability specific to the pediatric population is ontogeny, where age-specific changes during development may require dose adjustments to obtain the same levels of drug exposure and response. With significant improvements in characterizing both the ontogeny and genetic contributions of drug metabolizing enzymes, the time is right to begin placing more emphasis on …

The downregulation of the DNA damage response (DDR) enables aggressive tumors to achieve uncontrolled proliferation against replication stress, but the mechanisms underlying this process in tumors are relatively complex. Here, we demonstrate a mechanism through which a distinct E3 ubiquitin ligase, ITCH, modulates DDR machinery in triple-negative breast cancer (TNBC). We found that expression of a nuclear form of ITCH was significantly increased in human TNBC cell lines and tumor specimens. Phosphorylation of ITCH at Ser257 by AKT led to the nuclear localization of ITCH and ubiquitination of H1.2. The ITCH-mediated polyubiquitination of H1.2 suppressed RNF8/RNF168-dependent formation of 53BP1 foci, …
