Faculty, Staff and Students Publications

Gene expression analyses suggest that more than 1000-2000 genes are expressed predominantly in mouse and human testes. Although functional analyses of hundreds of these genes have been performed, there are still many testis-enriched genes whose functions remain unexplored. Analyzing gene function using knockout (KO) mice is a powerful tool to discern if the gene of interest is essential for sperm formation, function, and male fertility in vivo. In this study, we generated KO mice for 12 testis-enriched genes, 1700057G04Rik, 4921539E11Rik, 4930558C23Rik, Cby2, Ldhal6b, Rasef, Slc25a2, Slc25a41, Smim8, Smim9, Tmem210, and Tomm20l, using the clustered regularly interspaced short palindromic repeats /CRISPR-associated …

The genetic basis for the emergence of creativity in modern humans remains a mystery despite sequencing the genomes of chimpanzees and Neanderthals, our closest hominid relatives. Data-driven methods allowed us to uncover networks of genes distinguishing the three major systems of modern human personality and adaptability: emotional reactivity, self-control, and self-awareness. Now we have identified which of these genes are present in chimpanzees and Neanderthals. We replicated our findings in separate analyses of three high-coverage genomes of Neanderthals. We found that Neanderthals had nearly the same genes for emotional reactivity as chimpanzees, and they were intermediate between modern humans and …

Functional Studies Of Genetic Variants Associated With Human Diseases In Notch Signaling-Related Genes Using Drosophila, Sheng-An Yang, Jose L Salazar, David Li-Kroeger, Shinya Yamamoto

Duncan NRI Faculty and Staff Publications

Rare variants in the many genes related to Notch signaling cause diverse Mendelian diseases that affect myriad organ systems. In addition, genome- and exome-wide association studies have linked common and rare variants in Notch-related genes to common diseases and phenotypic traits. Moreover, somatic mutations in these genes have been observed in many types of cancer, some of which are classified as oncogenic and others as tumor suppressive. While functional characterization of some of these variants has been performed through experimental studies, the number of ‘variants of unknown significance’ identified in patients with diverse conditions keeps increasing as high-throughput sequencing technologies …

Emerging Roles Of Alternative Cleavage And Polyadenylation (Apa) In Human Disease, Prakash Dharmalingam, Rajasekaran Mahalingam, Hari Krishna Yalamanchili, Tingting Weng, Harry Karmouty-Quintana, Ashrith Guha, Rajarajan A Thandavarayan

Duncan NRI Faculty and Staff Publications

In the messenger RNA (mRNA) maturation process, the 3'-end of pre-mRNA is cleaved and a poly(A) sequence is added, this is an important determinant of mRNA stability and its cellular functions. More than 60%-70% of human genes have three or more polyadenylation (APA) sites and can be cleaved at different sites, generating mRNA transcripts of varying lengths. This phenomenon is termed as alternative cleavage and polyadenylation (APA) and it plays role in key biological processes like gene regulation, cell proliferation, senescence, and also in various human diseases. Loss of regulatory microRNA binding sites and interactions with RNA-binding proteins leading to …

Surgical Intervention For Phlegmasia Cerulea Dolens In A 61-Year-Old Cancer Patient, Christopher Ruben-Castillo, Cesar Cuen-Ojeda, Gabriel Lopez-Peña, Javier E Anaya-Ayala, Carlos A Hinojosa

The Texas Heart Institute Journal

Phlegmasia cerulea dolens, a rare and potentially fatal complication of acute deep vein thrombosis, is characterized by substantial edema, intense pain, and cyanosis. Phlegmasia cerulea dolens may compromise limb perfusion and lead to acute ischemia, gangrene, amputation, and death. We present the case of a 61-year-old woman with a history of breast cancer who had signs and symptoms of phlegmasia cerulea dolens in her left leg. She was treated promptly with open surgical thrombectomy and sequential distal compression with use of an Esmarch bandage to ensure complete thrombus extraction. These techniques restored venous flow and saved her leg. Open surgical …

Mapping Replication Timing In Single Mammalian Cells, Daniel A Bartlett, Vishnu Dileep, Timour Baslan, David M Gilbert

Faculty, Staff and Students Publications

Replication timing (RT) is the temporal order in which genomic DNA is replicated during S phase. Early and late replication correlate with transcriptionally active and inactive chromatin compartments, but mechanistic links between large scale chromosome structure, transcription, and replication are still enigmatic. A proper RT program is necessary to maintain the global epigenome that defines cell identity, suggesting that RT is critical for epigenome integrity by facilitating the assembly of different types of chromatin at different times during S phase. RT is regulated during development and it has been found to be altered in disease. Thus, RT can identify stable …

Ret Signaling Pathway And Ret Inhibitors In Human Cancer, Angelina T Regua, Mariana Najjar, Hui-Wen Lo

Faculty, Staff and Student Publications

Rearranged during transfection (RET) receptor tyrosine kinase was first identified over thirty years ago as a novel transforming gene. Since its discovery and subsequent pathway characterization, RET alterations have been identified in numerous cancer types and are most prevalent in thyroid carcinomas and non-small cell lung cancer (NSCLC). In other tumor types such as breast cancer and salivary gland carcinomas, RET alterations can be found at lower frequencies. Aberrant RET activity is associated with poor prognosis of thyroid and lung carcinoma patients, and is strongly correlated with increased risk of distant metastases. RET aberrations encompass a variety of genomic or …

Does The Novel Coronavirus Use The Ocular Surface As An Entrance Into The Body Or As An Infection Site?, Remzi Karadag, Alp Kayiran, Christopher J Rapuano

Wills Eye Hospital Papers

This study attempts to review whether the coronavirus disease-2019 (COVID-19) is transmitted through the ocular surface and examine the symptoms and signs of ocular disease. Considering that COVID-19 is transmitted by airborne droplets and close contact with infected individuals, we will also review the conditions to which eye clinics and ophthalmologists should pay attention to prevent the transmission of the disease. Although some researchers have argued that COVID-19 transmission cannot occur through the ocular surface, most of them are of the opinion that the ocular surface is a potential pathway of transmission. Until date, ocular signs and symptoms have been …

Depletion And Enrichment Of Phytosterols In Soybean Oil Lipid Emulsions Directly Associate With Serum Markers Of Cholestasis In Preterm Parenteral Nutrition-Fed Pigs, Greg Guthrie, Barbara Stoll, Shaji Chacko, Mahmoud Mohammad, Candace Style, Mariatu Verla, Oluyinka Olutoye, Deborah Schady, Charlotte Lauridsen, Nick Tataryn, Douglas Burrin

Children’s Nutrition Research Center Staff Publications

Background: Clinical reports show a positive correlation between phytosterol concentrations and severity of cholestatic liver disease markers in infants during long-term administration of parenteral lipid emulsions. Establishing a causal link between phytosterols and cholestasis has been complicated by confounding factors of lipid emulsion load, fatty acid composition, and vitamin E in many of these studies. The goal of this study is to determine whether altering the phytosterol concentration within a common soybean oil-based emulsion will alter the onset and severity of cholestasis in parenterally fed preterm piglets.

Methods: Preterm piglets were administered, for 21 days, either enteral nutrition (ENT) or …

How Do Low-Income Single-Mothers Get By When Unemployment Strikes: Patterns Of Multiple Program Participation After Transition From Employment To Unemployment, Chi-Fang Wu, Yu-Ling Chang, Soohyun Yoon, Salma Musaad

Children’s Nutrition Research Center Staff Publications

Little is known about longitudinal patterns of welfare program participation among single mothers after they transition from employment to unemployment. To better understand how utilization patterns of these welfare programs may change during the 12 months after a job loss, we used the 2008 Survey of Income and Program Participation to examine the patterns of participation in Medicaid, the Supplemental Nutrition Assistance Program, Temporary Assistance for Needy Families, and unemployment insurance among 342 single mothers who transitioned from employment to unemployment during the Great Recession. Using sequence analysis and cluster analysis, this paper identified four distinct patterns of program participation: …

Leveraging Large Multi-Center Cohorts Of Alzheimer Disease Endophenotypes To Understand The Role Of Klotho Heterozygosity On Disease Risk, Muhammad Ali, Yun Ju Sung, Fengxian Wang, Maria V. Fernández, John C. Morris, Anne M. Fagan, Richard J. Perrin, Carlos Cruchaga, Et Al

Open Access Publications

Two genetic variants in strong linkage disequilibrium (rs9536314 and rs9527025) in the Klotho (KL) gene, encoding a transmembrane protein, implicated in longevity and associated with brain resilience during normal aging, were recently shown to be associated with Alzheimer disease (AD) risk in cognitively normal participants who are APOE ε4 carriers. Specifically, the participants heterozygous for this variant (KL-SVHET+) showed lower risk of developing AD. Furthermore, a neuroprotective effect of KL-VSHET+ has been suggested against amyloid burden for cognitively normal participants, potentially mediated via the regulation of redox pathways. However, inconsistent associations and a smaller sample size of existing studies pose …

One-Carbon Metabolism In Children With Marasmus And Kwashiorkor, Thaddaeus May, Bethany De La Haye, Gabrielle Nord, Kevin Klatt, Kevin Stephenson, Sara Adams, Lucy Bollinger, Neil Hanchard, Erland Arning, Teodoro Bottiglieri, Kenneth Maleta, Mark Manary, Farook Jahoor

Open Access Publications

BACKGROUND: Kwashiorkor is a childhood syndrome of edematous malnutrition. Its precise nutritional precipitants remain uncertain despite nine decades of study. Remarkably, kwashiorkor's disturbances resemble the effects of experimental diets that are deficient in one-carbon nutrients. This similarity suggests that kwashiorkor may represent a nutritionally mediated syndrome of acute one-carbon metabolism dysfunction. Here we report findings from a cross-sectional exploration of serum one-carbon metabolites in Malawian children.

METHODS: Blood was collected from children aged 12-60 months before nutritional rehabilitation: kwashiorkor (N = 94), marasmic-kwashiorkor (N = 43) marasmus (N = 118), moderate acute malnutrition (N = 56) and controls (N = …

BACKGROUND: Recent evidence indicates a potential therapeutic role of fluvoxamine for COVID-19. In the TOGETHER trial for acutely symptomatic patients with COVID-19, we aimed to assess the efficacy of fluvoxamine versus placebo in preventing hospitalisation defined as either retention in a COVID-19 emergency setting or transfer to a tertiary hospital due to COVID-19.

METHODS: This placebo-controlled, randomised, adaptive platform trial done among high-risk symptomatic Brazilian adults confirmed positive for SARS-CoV-2 included eligible patients from 11 clinical sites in Brazil with a known risk factor for progression to severe disease. Patients were randomly assigned (1:1) to either fluvoxamine (100 mg twice …

Mean Lifetime Survival Estimates Following Solid Organ Transplantation In The Us And Uk, Christopher N Graham, Crystal Watson, Arie Barlev, Matt Stevenson, Vikas R Dharnidharka

Open Access Publications

AIMS: Accurately estimating mean survival after solid organ transplant (SOT) is crucial for efficient healthcare resource allocation decisions. However, registry-based post-transplant recipient survival estimates vary greatly and are incomplete. Often, the methods used in lifetime survival extrapolation may not fit complex transplant data and therefore alternative methods are required. We aimed to explore the flexible cubic spline methodology as a meaningful alternative for estimating lifetime survival following SOT.

METHODS: Survival analyses were conducted in kidney, liver, heart, and lung transplant recipients. Mean survival was estimated using flexible cubic splines on the hazard scale fitted with three knots, based on where …
