Identifying Patters of Doxorubicin Sensitivity in Soft Tissue Sarcoma Using Next Generation Sequencing Identifying Patters of Doxorubicin Sensitivity in Soft Tissue Sarcoma Using Next Generation Sequencing THESIS Presented in Partial Fulfillment of the Requirements for the Degree Master of Public Health in the Graduate School of The Ohio State University By Manojkumar Bupathi Graduate Program in Public Health The Ohio State University 2017 Thesis Committee: Professor James Chen – Advisor Professor Philip Binkley Professor Gregory Otterson Professor Brian Hilligoss Copyright by Manojkumar Bupathi 2017 Abstract Soft-tissue sarcomas account for less than 1% of new cancer diagnoses in both men and women in the United States. Surgery is offered for localized disease amenable to resection. However, less than 20% of patients present with initially resectable disease, and the 5-year survival rate for this locally advanced/metastatic population is abysmal (<25%). Sadly, our ability to systemically treat metastatic soft tissue sarcoma chemotherapy remains a case of trial-and-error. Indeed, the National Cancer Center Network guidelines list nine acceptable single agents and six different combination regimens. Doxorubicin serves as the backbone of most treatment regimens but induces significant tumor regression in only 15-30% of patients. We conducted a retrospective review of patients with leiomyosarcoma who were treated at our institution and had next generation sequencing with FoundationOne. Our aim was to determine if we could determine sensitivity to doxorubicin and other agents that are commonly used to treat STS based on p53 status. Our data indicates that the type of abnormality in p53 can have prognostic implications with doxorubicin and pazopanib. Further, we performed a cluster analysis to determine if there are any specific patterns in genetic pathways which could identify be used to group patients together. Using the leiomyosarcoma database in TCGA and GENIE, we generated the same clusters for those patients to compare the patients between the datasets. We found that there are similarities among along three datasets. For example, most male patients with leiomyosarcoma fall into cluster 3. The exact ii mechanism of why this happens is currently not known. In addition, patients in cluster 2 in TCGA perform worse compared to our dataset. However, patients in our dataset were treated with targeted therapy suggesting that molecular directed therapy could have better outcomes. Finally, we identified 10 patients with BRCA alterations. Four out of six patients with BRCA2 alterations had the same variance of unknown significance alteration at K33226x. This specific alteration has been associated with increased risk in breast, ovarian, pancreas and lung cancer. Given the high prevalence of this alteration in our cohort, it is important for this be evaluated in other datasets to get a better understanding of its prevalence so that patients can appropriately be screened or counseled regarding their risks. Though precision medicine focuses on individualized care success truly requires a population-based approach and understanding what interventions work on individual need to be compared with data from large, diverse numbers of people to identify population subgroups likely to respond differently to intervention. iii Dedication This document is dedicated to my family. iv Acknowledgments I would like to express my appreciation to my advisory committee: Dr. James Chen, Dr. John Hays, and Dr. Philip Binkley.

Critics of inclusive fitness argue, correctly, that it is not an ideal fitness concept for the purpose of predicting gene- frequency change, since it relies on assumptions about the causal structure of social interaction that are unlikely to be exactly true in real populations, and that hold as approximations only given a specific type of weak selection.

  • I Xio- and Made the Rather Curious Assumption That the Mutant Is
    NOTES AND COMMENTS NATURAL SELECTION AND THE EVOLUTION OF DOMINANCE P. M. SHEPPARD Deportment of Genetics, University of Liverpool and E.B. FORD Genetic Laboratories, Department of Zoology, Oxford 1. INTRODUCTION CROSBY(i 963) criticises the hypothesis that dominance (or recessiveness) has evolved and is not an attribute of the allelomorph when it arose for the first time by mutation. None of his criticisms is new and all have been discussed many times. However, because of a number of apparent mis- understandings both in previous discussions and in Crosby's paper, and the fact that he does not refer to some important arguments opposed to his own view, it seems necessary to reiterate some of the previous discussion. Crosby's criticisms fall into two parts. Firstly, he maintains, as did Wright (1929a, b) and Haldane (1930), that the selective advantage of genes modifying dominance, being of the same order of magnitude as the mutation rate, is too small to have any evolutionary effect. Secondly, he criticises, as did Wright (5934), the basic assumption that a new mutation when it first arises produces a phenotype somewhat intermediate between those of the two homozygotes. 2.THE SELECTION COEFFICIENT INVOLVED IN THE EVOLUTION OF DOMINANCE Thereis no doubt that the selective advantage of modifiers of dominance is of the order of magnitude of the mutation rate of the gene being modified. Crosby (p. 38) considered a hypothetical example with a mutation rate of i xio-and made the rather curious assumption that the mutant is dominant in the absence of modifiers of dominance.

  • Using Drosophila to Teach Genetics
    Curriculum Units by Fellows of the Yale-New Haven Teachers Institute 1996 Volume V: Genetics in the 21st Century: Destiny, Chance or Choice Using Drosophila to Teach Genetics Curriculum Unit 96.05.01 by Christin E. Arnini The objectives of this unit are to take basic concepts of genetics and apply them to an organism, easily raised and observed in the classroom. It has been a challenge in the teaching of High School Biology, to take the abstract ideas of genes, chromosomes, heredity, and make them visable and tangible for the students. Drosophila melanogaster offers a way for teachers to help students make connections between populations, the organism, the cell, the chromosome, the gene, and the DNA. As a part of a unit on genetics, this unit on Drosophila can give students the opportunity to get to know an organism well, observing closely its development and physical characteristics, and then questioning how it is that the fly came to be this way.

Computational and Systems Biology, Rothamsted, Harpenden, Herts. * corresponding author email: [email protected] 1 Abstract Plant domestication involved a process of selection through human agency of a series of traits collectively termed the domestication syndrome. Current debate concerns the pace at which domesticated plants emerged from cultivated wild populations and how many genes were involved. Here we present simulations that test how many genes could have been involved by considering the cost of selection. We demonstrate the selection load that can be endured by populations increases with decreasing selection coefficients and greater numbers of loci down to values of about s = 0.005, causing a driving force that increases the number of loci under selection. As the number of loci under selection increases, an effect of co-selection increases resulting in individual unlinked loci being fixed more rapidly in out-crossing populations, representing a second driving force to increase the number of loci under selection. In inbreeding systems co-selection results in interference and reduced rates of fixation but does not reduce the size of the selection load that can be endured. These driving forces result in an optimum pace of genome evolution in which 50-100 loci are the most that could be under selection in a cultivation regime. Furthermore, the simulations do not preclude the existence of selective sweeps but demonstrate that they come at a cost of the selection load that can be endured and consequently a reduction of the capacity of plants to adapt to new environments, which may contribute to the explanation of why selective sweeps have been so rarely detected in genome studies.

  • How Genetic Engineering Differs from Conventional Breeding Hybridization
    GENETIC ENGINEERING IS NOT AN EXTENSION OF CONVENTIONAL PLANT BREEDING; How genetic engineering differs from conventional breeding, hybridization, wide crosses and horizontal gene transfer by Michael K. Hansen, Ph.D. Research Associate Consumer Policy Institute/Consumers Union January, 2000 Genetic engineering is not just an extension of conventional breeding. In fact, it differs profoundly. As a general rule, conventional breeding develops new plant varieties by the process of selection, and seeks to achieve expression of genetic material which is already present within a species. (There are exceptions, which include species hybridization, wide crosses and horizontal gene transfer, but they are limited, and do not change the overall conclusion, as discussed later.) Conventional breeding employs processes that occur in nature, such as sexual and asexual reproduction. The product of conventional breeding emphasizes certain characteristics. However these characteristics are not new for the species. The characteristics have been present for millenia within the genetic potential of the species. Genetic engineering works primarily through insertion of genetic material, although gene insertion must also be followed up by selection. This insertion process does not occur in nature. A gene “gun”, a bacterial “truck” or a chemical or electrical treatment inserts the genetic material into the host plant cell and then, with the help of genetic elements in the construct, this genetic material inserts itself into the chromosomes of the host plant. Engineers must also insert a “promoter” gene from a virus as part of the package, to make the inserted gene express itself. This process alone, involving a gene gun or a comparable technique, and a promoter, is profoundly different from conventional breeding, even if the primary goal is only to insert genetic material from the same species.

    viruses Review Antiviral RNAi in Insects and Mammals: Parallels and Differences Susan Schuster, Pascal Miesen and Ronald P. van Rij * Department of Medical Microbiology, Radboud University Medical Center, Radboud Institute for Molecular Life Sciences, 6500 HB Nijmegen, The Netherlands; [email protected] (S.S.); [email protected] (P.M.) * Correspondence: [email protected]; Tel.: +31-24-3617574 Received: 16 April 2019; Accepted: 15 May 2019; Published: 16 May 2019 Abstract: The RNA interference (RNAi) pathway is a potent antiviral defense mechanism in plants and invertebrates, in response to which viruses evolved suppressors of RNAi. In mammals, the first line of defense is mediated by the type I interferon system (IFN); however, the degree to which RNAi contributes to antiviral defense is still not completely understood. Recent work suggests that antiviral RNAi is active in undifferentiated stem cells and that antiviral RNAi can be uncovered in differentiated cells in which the IFN system is inactive or in infections with viruses lacking putative viral suppressors of RNAi. In this review, we describe the mechanism of RNAi and its antiviral functions in insects and mammals. We draw parallels and highlight differences between (antiviral) RNAi in these classes of animals and discuss open questions for future research. Keywords: small interfering RNA; RNA interference; RNA virus; antiviral defense; innate immunity; interferon; stem cells 1. Introduction RNA interference (RNAi) or RNA silencing was first described in the model organism Caenorhabditis elegans [1] and following this ground-breaking discovery, studies in the field of small, noncoding RNAs have advanced tremendously. RNAi acts, with variations, in all eukaryotes ranging from unicellular organisms to complex species from the plant and animal kingdoms [2].

  • Suppression Mechanisms Reviews Suppression Mechanisms Themes from Variations
    Suppression mechanisms Reviews Suppression mechanisms themes from variations Suppressor analysis is a commonly used strategy to identify functional relationships between genes that might not have been revealed through other genetic or biochemical means. Many mechanisms that explain the phenomenon of genetic suppression have been described, but the wide variety of possible mechanisms can present a challenge to defining the relationship between a suppressor and the original gene. This article provides a broad framework for classifying suppression mechanisms and describes a series of genetic tests that can be applied to determine the most likely mechanism of suppression. he analysis of any biological process by classical genetic basis for distinguishing the classes, allowing the investigator Tmethods ultimately requires multiple types of mutant to: (1) pursue the class that best suits their particular interests; selections to identify all the genes involved in that process.

Modifiers that result considered when designing suppressor hunts (Box 1). in a more severe phenotype are termed enhancers, while mutations that restore a more wild-type phenotype despite Intragenic suppression the continued presence of the original mutation are termed The simplest suppression mechanism to conceptualize is suppressors.
