Biomarkers Beyond Brca: Promising Combinatorial Treatment Strategies In Overcoming Resistance To Parp Inhibitors, Yu-Yi Chu, Clinton Yam, Hirohito Yamaguchi, Mien-Chie Hung

Faculty, Staff and Student Publications

Poly (ADP-ribose) polymerase (PARP) inhibitors (PARPi) exploit the concept of synthetic lethality and offer great promise in the treatment of tumors with deficiencies in homologous recombination (HR) repair. PARPi exert antitumor activity by blocking Poly(ADP-ribosyl)ation (PARylation) and trapping PARP1 on damaged DNA. To date, the U.S. Food and Drug Administration (FDA) has approved four PARPi for the treatment of several cancer types including ovarian, breast, pancreatic and prostate cancer. Although patients with HR-deficient tumors benefit from PARPi, majority of tumors ultimately develop acquired resistance to PARPi. Furthermore, even though BRCA1/2 mutations are commonly used as markers of PARPi sensitivity in …

Mindfulness In University Students: A Tool For Managing Stress, Lyndsey Kunzler

Family Perspectives

Mindfulness can be a meaningful practice across different stages of life: it can help improve well-being for young children (Becker & Whitaker, 2018; Esmaeilian et al., 2018; Li et al., 2019), adolescents (Leavitt et al., 2020; Oppo et al., 2019), and adults (Berk et al., 2018; Pierson et al., 2019). Mindfulness is the act of clearing the mind, being present, and paying attention with the intent to improve well-being (Greeson et al., 2014). Mindfulness began as a common Buddhist practice, but in the 1970s Jon Kabat-Zinn created mindfulness-based stress reduction (MBSR) in an attempt to aid mental health issues (Greeson …

Effects Of Parents’ Avoidant And Anxious Attachment On Children, Nicole Busacker

Family Perspectives

Avoidant and anxious attachment styles are both negative ways of dealing with the need for connection or bonding. One reason these attachment styles develop is in “the absence of a secure bond with an available and responsive ‘other,’ rigid, repetitive internal and interpersonal coping patterns or attachment strategies develop” (Brubacher, 2017, p. 52–53). These coping patterns are made manifest in either avoidant or anxious attachment behaviors and are mainly expressed in relation to spouses and children.

Subtype C Hiv-1 Reservoirs Throughout The Body In Art-Suppressed Individuals, Zhou Liu, Peter Julius, Guobin Kang, John T. West, Charles Wood

School of Biological Sciences: Faculty Publications

Subtype B HIV-1 reservoirs have been intensively investigated, but reservoirs in other subtypes and how they respond to antiretroviral therapy (ART) is substantially less established. To characterize subtype C HIV-1 reservoirs, we implemented postmortem frozen, as well as formalin fixed paraffin embedded (FFPE) tissue sampling of central nervous system (CNS) and peripheral tissues. HIV-1 LTR, gag, envelope (env) DNA and RNA was quantified using genomic DNA and RNA extracted from frozen tissues. RNAscope was used to localize subtype C HIV-1 DNA and RNA in FFPE tissue. Despite uniform viral load suppression in our cohort, PCR results …

Association Between Use Of Remdesivir And Bradycardia, Gibret Umeukeje

Remdesivir received the first emergency use authorization from the FDA for the treatment of COVID-19. Multiple adverse drug reactions (ADR) have been reported since its approval in October 2020. Bradycardia, defined by a decrease in heart rate has been reported as an adverse event for patients receiving remdesivir for COVID-19 treatment. The purpose of the research is to systematically investigate the frequency of occurrence of bradycardia in adults receiving remdesivir using clinical data derived from the FDA Adverse Event Reporting System (FAERS) database. Patients receiving remdesivir were compared to those receiving Paxlovid, Regen-Cov, and Dexamethasone for COVID-19 treatment to see …

Correlation Of Phosphorus Adsorption With Chemical Properties Of Aluminum-Based Drinking Water Treatment Residuals Collected From Various Parts Of The United States, Roxana Rahmati, Virinder Sidhu, Rosita Nunez, Rupali Datta, Dibyendu Sarkar

Michigan Tech Publications, Part 1

Over the past several decades, the value of drinking water treatment residuals (WTRs), a byproduct of the coagulation process during water purification, has been recognized in various environmental applications, including sustainable remediation of phosphorus (P)-enriched soils. Aluminum-based WTRs (Al-WTRs) are suitable adsorbent materials for P, which can be obtained and processed inexpensively. However, given their heterogeneous nature, it is essential to identify an easily analyzable chemical property that can predict the capability of Al-WTRs to bind P before soil amendment. To address this issue, thirteen Al-WTRs were collected from various geographical locations around the United States. The non-hazardous nature of …

Phosphorus And Heavy Metals Removal From Stormwater Runoff Using Granulated Industrial Waste For Retrofitting Catch Basins, Viravid Na Nagara, Dibyendu Sarkar, Rupali Datta

Michigan Tech Publications, Part 1

Phosphorus and heavy metals are washed off and transported with stormwater runoff to nearby surface water bodies resulting in environmental and human health risks. Catch basins remain one of the primary gateways through which stormwater runoff and pollutants from urban areas are transported. Retrofitting catch basins to enhance their phosphorus and heavy metal removal can be an effective approach. In this study, aluminum-based water treatment residual (WTR, a non-hazardous byproduct of the water treatment process) was granulated via a green method to serve as a sustainable filter material, called WTR granules, for enhancing the capabilities of catch basins to remove …

Incidence Of Drug-Resistant Enterobacteriaceae Strains In Organic And Conventional Watermelons Grown In Tennessee, Onyekachukwu Akaeze, Agnes Kilonzo-Nthenge, Dilip Nandwani, Abdullah Ibn Mafiz, Maureen Nzomo, Tobenna Aniume

Agricultural and Environmental Sciences Faculty Research

The production and consumption of organic fresh produce have constantly increased since the 1990s. Consumers prefer organic produce because it does not contain synthetic chemical residues that are often implicated in health problems. The contamination of fresh produce by pathogenic Enterobacteriaceae strains remains a major challenge, and is responsible for frequent foodborne disease outbreaks. The use of antibiotics has proved an effective treatment, but the increase in occurrences of antibiotic resistance is becoming a health challenge. This study seeks to establish the presence of antimicrobial resistance in Enterobacteriaceae on organic and conventional watermelon fruits. Watermelons used for this study were …

Ocean Acidification Does Not Overlook Sex: Review Of Understudied Effects And Implications Of Low Ph On Marine Invertebrate Sexual Reproduction, Jacqueline L. Padilla-Gamiño, Lindsay Alma, Laura H. Spencer, Yaamini R. Venkataraman, Leah Wessler

Biology

Sexual reproduction is a fundamental process essential for species persistence, evolution, and diversity. However, unprecedented oceanographic shifts due to climate change can impact physiological processes, with important implications for sexual reproduction. Identifying bottlenecks and vulnerable stages in reproductive cycles will enable better prediction of the organism, population, community, and global-level consequences of ocean change. This article reviews how ocean acidification impacts sexual reproductive processes in marine invertebrates and highlights current research gaps. We focus on five economically and ecologically important taxonomic groups: cnidarians, crustaceans, echinoderms, molluscs and ascidians. We discuss the spatial and temporal variability of experimental designs, identify trends …

Rgs12 Polarizes The Gpsm2-Gnai Complex To Organize And Elongate Stereocilia In Sensory Hair Cells., Anil Akturk, Matthew Day, Basile Tarchini

Faculty Research 2022

Inhibitory G proteins (GNAI/Gα(i)) bind to the scaffold G protein signaling modulator 2 (GPSM2) to form a conserved polarity complex that regulates cytoskeleton organization. GPSM2 keeps GNAI in a guanosine diphosphate (GDP)-bound state, but how GPSM2-GNAI is generated or relates to heterotrimeric G protein signaling remains unclear. We find that RGS12, a GTPase-activating protein (GAP), is required to polarize GPSM2-GNAI at the hair cell apical membrane and to organize mechanosensory stereocilia in rows of graded heights. Accordingly, RGS12 and the guanine nucleotide exchange factor (GEF) DAPLE are asymmetrically co-enriched at the hair cell apical junction, and Rgs12 mouse mutants are …

Mitigating The Adverse Effects Of Semi-Arid Climate On Capsicum Cultivation By Using The Retractable Roof Production System, Giao N. Nguyen, Neil Lantzke

Horticulture Research Articles

Capsicum (Capsicum annuum L.) belongs to the Solanaceae family and is an economically important vegetable crop. However, the crop is very sensitive to adverse weather conditions such as high temperatures and excessive sunlight, which cause flower and young fruit to drop and sunscald to mature fruits. Using protected cultivation such as shade covers or net houses is a feasible agronomic approach to protect the crop from high light intensity, which increases plant growth, reduces fruit damage, and increases marketable fruit yield and quality. Low-cost protected cropping options such as fixed-roof net houses have proved cost-effective and suitable for fruiting vegetable …

Inhibiting Glutamine Utilization Creates A Synthetic Lethality For Suppression Of Atp Citrate Lyase In Kras-Driven Cancer Cells, Ahmet Hatipoglu, Deepak Menon, Talia Levy, Maria A. Frias, David A. Foster

Publications and Research

Metabolic reprogramming is now considered a hallmark of cancer cells. KRas-driven cancer cells use glutaminolysis to generate the tricarboxylic acid cycle intermediate α -ketoglutarate via a transamination reaction between glutamate and oxaloacetate. We reported previously that exogenously supplied unsaturated fatty acids could be used to synthesize phosphatidic acid–a lipid second messenger that activates both mammalian target of rapamycin (mTOR) complex 1 (mTORC1) and mTOR complex 2 (mTORC2). A key target of mTORC2 is Akt–a kinase that promotes survival and regulates cell metabolism. We report here that mono- unsaturated oleic acid stimulates the phosphoryla tion of ATP citrate lyase (ACLY) at …

Faculty, Staff and Student Publications

BACKGROUND: The current COVID-19 pandemic and the previous SARS/MERS outbreaks of 2003 and 2012 have resulted in a series of major global public health crises. We argue that in the interest of developing effective and safe vaccines and drugs and to better understand coronaviruses and associated disease mechenisms it is necessary to integrate the large and exponentially growing body of heterogeneous coronavirus data. Ontologies play an important role in standard-based knowledge and data representation, integration, sharing, and analysis. Accordingly, we initiated the development of the community-based Coronavirus Infectious Disease Ontology (CIDO) in early 2020.

Background: Moraxella bovis and Moraxella bovoculi both associate with infectious bovine keratoconjunctivitis (IBK), an economically significant and painful ocular disease that affects cattle worldwide. There are two genotypes of M. bovoculi (genotypes 1 and 2) that differ in their gene content and potential virulence factors, although neither have been experimentally shown to cause IBK. M. bovis is a causative IBK agent, however, not all strains carry a complete assortment of known virulence factors. The goals of this study were to determine the population structure and depth of M. bovis genomic diversity, and to compare core and accessory genes and …

Evidence For Phylogenetic Signal And Correlated Evolution In Plant-Water Relations Traits, Eleinis Ávila-Lovera, Klaus Winter, Gregory R. Goldsmith

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Evolutionary relationships are likely to play a significant role in shaping plant physiological and structural traits observed in contemporary taxa. We review research on phylogenetic signal and correlated evolution in plant-water relations traits, which play important roles in allowing plants to acquire, use and conserve water. We found more evidence for a phylogenetic signal in structural traits (e.g., stomatal length, stomatal density) than in physiological traits (e.g., stomatal conductance, water potential at turgor loss). Although water potential at turgor loss is the most-studied plant-water relations trait in an evolutionary context, it is the only trait consistently found to not have …

Unraveling The Pathways Involved In Intestinal Repair After Ionizing Radiation Damage, Blaine Pattavina

Natural Sciences and Mathematics | Biological Sciences Master's Theses

Exposure to genotoxic environmental agents has detrimental effects on health span and aging. Macromolecular damage caused by these factors is also known to lead to diseases like cancer. Radiation therapy is the treatment of choice for malignant tumors and several non-malignant diseases. Despite its effectiveness, it often leads to unintended complications. Radio-sensitivity of healthy ‘bystander’ cells is an important factor in mediating these complications, which often result in several long-term and debilitating side effects. This incurs huge costs in patient care to maintain the well-being of survivors. Current efforts to understand the underlying molecular patho-physiology of radiation damage involve the …

Genomics And Transcriptomics To Protect Rice (Oryza Sativa L.) From Abiotic Stressors: -Pathways To Achieving Zero Hunger, Mushtaq Ahmad

Center for Plant Science Innovation: Faculty Publications

More over half of the world’s population depends on rice as a major food crop. Rice (Oryza sativa L.) is vulnerable to abiotic challenges including drought, cold, and salinity since it grown in semi-aquatic, tropical, or subtropical settings. Abiotic stress resistance has bred into rice plants since the earliest rice cultivation techniques. Prior to the discovery of the genome, abiotic stressrelated genes were identified using forward genetic methods, and abiotic stress-tolerant lines have developed using traditional breeding methods. Dynamic transcriptome expression represents the degree of gene expression in a specific cell, tissue, or organ of an individual organism at …
