This article is published with open access Abstract Our current knowledge of host–virus interactions in biofilms is limited to computational predictions based on laboratory experiments with a small number of cultured bacteria. However, natural biofilms are diverse and chiefly composed of uncultured bacteria and archaea with no viral infection patterns and lifestyle predictions described to date. Herein, we predict the first DNA sequence-based host–virus interactions in a natural biofilm. Using single-cell genomics and metagenomics – 1234567890();,: 1234567890();,: applied to a hot spring mat of the Cone Pool in Mono County, California, we provide insights into virus host range, lifestyle and distribution across different mat layers. Thirty-four out of 130 single cells contained at least one viral contig (26%), which, together with the metagenome-assembled genomes, resulted in detection of 59 viruses linked to 34 host species.

  • Personal Genomic Information Management and Personalized Medicine: Challenges, Current Solutions, and Roles of HIM Professionals
    Personal Genomic Information Management and Personalized Medicine: Challenges, Current Solutions, and Roles of HIM Professionals Personal Genomic Information Management and Personalized Medicine: Challenges, Current Solutions, and Roles of HIM Professionals by Amal Alzu’bi, MS; Leming Zhou, PhD; and Valerie Watzlaf, PhD, RHIA, FAHIMA Abstract In recent years, the term personalized medicine has received more and more attention in the field of healthcare. The increasing use of this term is closely related to the astonishing advancement in DNA sequencing technologies and other high-throughput biotechnologies. A large amount of personal genomic data can be generated by these technologies in a short time. Consequently, the needs for managing, analyzing, and interpreting these personal genomic data to facilitate personalized care are escalated. In this article, we discuss the challenges for implementing genomics-based personalized medicine in healthcare, current solutions to these challenges, and the roles of health information management (HIM) professionals in genomics-based personalized medicine. Introduction Personalized medicine utilizes personal medical information to tailor strategies and medications for diagnosing and treating diseases in order to maintain people’s health.1 In this medical practice, physicians combine results from all available patient data (such as symptoms, traditional medical test results, medical history and family history, and certain personal genomic information) so that they can make accurate diagnoses and determine

Scott Weber * Department of Microbiology and Molecular Biology, 4007 Life Sciences Building, 701 East University Parkway, Brigham Young University, Provo, UT 84602, USA; [email protected] (K.V.W.); [email protected] (J.A.T.) * Correspondence: [email protected]; Tel.: +1-801-422-6259 Received: 31 December 2019; Accepted: 22 January 2020; Published: 24 January 2020 Abstract: Since the completion of the Human Genome Project in 2003, genomic sequencing has become a prominent tool used by diverse disciplines in modern science. In the past 20 years, the cost of genomic sequencing has decreased exponentially,making it affordable and accessible. Bioinformatic and biological studies have produced significant scientific breakthroughs using the wealth of genomic information now available. Alongside the scientific benefit of genomics, companies offer direct-to-consumer genetic testing which provide health, trait, and ancestry information to the public. A key area that must be addressed is education about what conclusions can be made from this genomic information and integrating genomic education with foundational genetic principles already taught in academic settings. The promise of personal genomics providing disease treatment is exciting, but many challenges remain to validate genomic predictions and diagnostic correlations. Ethical and societal concerns must also be addressed regarding how personal genomic information is used. This genomics revolution provides a powerful opportunity to educate students, clinicians, and the public on scientific and ethical issues in a personal way to increase learning.

  • The ELSI Advisory Board GP-Write/ the Center of Excellence For
    ! The ELSI Advisory Board GP-write/ The Center of Excellence for Engineering Biology Background Information on GP-write, with ELSI dimensions The Genome Project-write (GP-write) is an open, international research project led by a multi- disciplinary group of scientific leaders who will oversee a reduction in the costs of engineering and testing large genomes, including a human genome, in cell lines by over 1,000-fold within ten years. The overarching goal of such an effort is to further our understanding of the blueprint for life provided by the Human Genome Project (HGP-read) by developing new technologies and an ethical framework for genome-scale engineering, as well as transformative medical applications. GP-write will include whole genome engineering of human cell lines and other organisms of significance to research and development, agriculture, and public health, as well as organoids derived from human cells. A coordinated scientific effort to understand, discuss, and apply large genome editing technologies is timely, and public discourse regarding such an endeavor is both expected and encouraged as GP-write gets underway. However, responsible innovation requires having more than ELSI discussions; it also involves identifying common goals important to scientists and the public through timely and detailed consultation among diverse stakeholders. The GP-write effort is aimed at technology development and knowledge creation, with the ultimate goal of improving life on Earth. Potential innovations relate to biomedical therapies, food supply management, biofuels, and public health. However, as with many other technology development initiatives, there is potential for misuse, and some risks may be unforeseen.
