The Gilbert S. Omenn Prize is awarded by the International Society for Evolution, Medicine, and Public Health for best article published each year on a topic related to evolution in the context of medicine and public health.  The prize for 2014 goes to, “Escape from bacterial iron piracy through rapid evolution of transferrin” by Matthew Barber and Nels Elde from the University of Utah. The article appeared in Science 346:1362-6, 2014. First author Matthew Barber, a postdoctoral student, will receive the $5,000 prize and present a talk on March 21 at the 2015 ISEMPH meeting in Tempe Arizona.  The prize is made possible by a generous donation from Gilbert Omenn.

The Prize Committee—Sarah Tishkoff, Joe Alcock, Noah Rosenberg, and Alison Galvani—found the paper impressive in its scope, integrating phylogenetic, bioinformatic, and experimental approaches to show that primate hosts and bacterial pathogens causing diseases such as meningitis, gonorrhea, and influenza, have co-evolved in competition for a key growth-limiting nutrient: iron.  Barber & Elde show that natural selection during primate evolution produced specific functional adaptations in the iron-binding protein transferrin that prevent iron piracy by bacterial transferrin binding protein (TbpA). This result is a vivid illustration of the role that natural selection and “nutritional immunity” play in host-pathogen “arms races”, mediated by recurrent episodes of positive selection between hosts and pathogens.

Three papers were selected for honorable mention. They are listed below in alphabetical order.

Byars, Sean G., Stephen C. Stearns, and Jacobus J. Boomsma. “Opposite risk patterns for autism and schizophrenia are associated with normal variation in birth size: phenotypic support for hypothesized diametric gene-dosage effects.” Proceedings of the Royal Society B: Biological Sciences 281.1794 (2014): 20140604.

This article uses extensive health registry data from 1978 – 2009 in Denmark to demonstrate associations between birth weight and risk patterns for autism and schizophrenia.  They argue that their findings add support to the hypothesis that genomic conflict and imprinting may play a role in common diseases whose etiology has been difficult to unravel using standard approaches.

Pennings, Pleuni S., Sergey Kryazhimskiy, and John Wakeley. “Loss and recovery of genetic diversity in adapting populations of HIV.” PLoS genetics10.1 (2014): e1004000.

This article uses a population genetics approach to infer effective population size of HIV infections based on the prevalence of “hard and soft” selective sweeps. This study helps to explain actual patterns of drug resistance evolution in patients and suggests evolutionary principles for strategies to keep drug resistance to a minimum.

Warinner, Christina, et al. “Pathogens and host immunity in the ancient human oral cavity.” Nature genetics 46.4 (2014): 336-344.

This article characterizes the microbiota from dental calculus obtained from ~1000 year old human skeletons, observing pathogens associated with disease in modern populations and also antibiotic resistance genes prior to the use of antibiotics to treat disease.

Please join the Society in congratulating the authors of the winning and runner up articles. Nominations for next year’s prize will be received starting early in 2016.  The Society also sponsors the $5,000 George C. Williams Prize for the best paper published each year in the Society’s flagship journal, Evolution, Medicine and Public Health. All papers published in the journal in 2015 will have author’s fees waived and will be automatically entered into the Prize competition.

 

 

 

Carina Schlebusch and colleagues just published an article in Molecular Biology and Evolution demonstrating human adaptation to the locally high arsenic levels in groundwater in the Argentine Andes. This work is the first to show a genetic adaptation that allows the detoxification of a environmental toxin (arsenic) in humans.

Title: Human adaptation to arsenic-rich environments

Abstract: “Adaptation drives genomic changes; however, evidence of specific adaptations in humans remains limited. We found that inhabitants of the northern Argentinean Andes, an arid region where elevated arsenic concentrations in available drinking water is common, have unique arsenic metabolism, with efficient methylation and excretion of the major metabolite dimethylated arsenic and a less excretion of the highly toxic monomethylated metabolite. We genotyped women from this population for 4,301,332 single nucleotide polymorphisms (SNPs) and found a strong association between the AS3MT (arsenic [+3 oxidation state] methyltransferase) gene and mono- and dimethylated arsenic in urine, suggesting that AS3MT functions as the major gene for arsenic metabolism in humans.

Carcinomas of the prostate are the most common cancers affecting men and a leading cause of male cancer deaths in the United States (CDC web site, Cancer Prevention and Control).  Given the unique association of the prostate with males, it makes sense that prosate carcinoma cells are often dependent for continued growth and proliferation on signaling by the androgen receptor, as andogens are primarily associated with physiological effects critical for male sexual development.  Therefore, therapies aimed at inhibiting either androgen synthesis or androgen receptor function make great sense. In a recent paper by Chen et al. (2014), Steven Balk and colleagues demonstrate that treatment of castration-resistant prostate cancer with a drug (abiraterone) that inhibits the production of androgens can select for mutant androgen receptors (AR) that more effectively recognize and get activated by a non-androgen.

Rodríguez JA, Marigorta UM, Navarro A. Integrating genomics into evolutionary medicine. Curr. Opin. Genet. Dev. 2014;29:97-102

Abstract: The application of the principles of evolutionary biology into medicine was suggested long ago and is already providing insight into the ultimate causes of disease. However, a full systematic integration of medical genomics and evolutionary medicine is still missing. Here, we briefly review some cases where the combination of the two fields has proven profitable and highlight two of the main issues hindering the development of evolutionary genomic medicine as a mature field, namely the dissociation between fitness and health and the still considerable difficulties in predicting phenotypes from genotypes. We use publicly available data to illustrate both problems and conclude that new approaches are needed for evolutionary genomic medicine to overcome these obstacles.

An Evolutionary Medicine Approach to Understanding Factors That Contribute to Chronic Obstructive Pulmonary Disease

 By Aoshiba K(1), Tsuji T, Itoh M, Yamaguchi K, Nakamura H.
Tokyo Medical University Ibaraki Medical Center, Inashiki, Japan.

Published in Respiration. 2015 Feb 10. [Epub ahead of print] (Not open access)

Although many studies have been published on the causes and mechanisms of chronic obstructive pulmonary disease (COPD), the reason for the existence of COPD and the reasons why COPD develops in humans have hardly been studied. Evolutionary medical approaches are required to explain not only the proximate factors, such as the causes and mechanisms of a disease, but the ultimate (evolutionary) factors as well, such as why the disease is present and why the disease develops in humans. According to the concepts of evolutionary medicine, disease susceptibility is acquired as a result of natural selection during the evolutionary process of traits linked to the genes involved in disease susceptibility. In this paper, we discuss the following six reasons why COPD develops in humans based on current evolutionary medical theories: (1) evolutionary constraints; (2) mismatch between environmental changes and evolution; (3) co-evolution with pathogenic microorganisms; (4) life history trade-off; (5) defenses and their costs, and (6) reproductive success at the expense of health. Our perspective pursues evolutionary answers to the fundamental question, ‘Why are humans susceptible to this common disease, COPD, despite their long evolutionary history?’ We believe that the perspectives offered by evolutionary medicine are essential for researchers to better understand the significance of their work.

Dr Darwin  an article By Timothy Gower, Art by Tim O’Brien  published in Proto, Winter, 2015   (open access)

Can a refresher course in the laws of natural selection help doctors better understand human health and illness?

ANDREW READ RECENTLY SPENT SIX MONTHS on the wards at the University of Michigan Medical Center, observing doctors who treat infectious disease. He recalls one patient, a woman whose bacterial pneumonia resisted treatment by every antibiotic available, and who perished after 18 months. “She died of uncontrolled evolution,” says Read, an evolutionary biologist at Pennsylvania State University who studies antimicrobial resistance. “One of my colleagues said, ‘This was a failure of our science,’ and I agree entirely. We did not know how to slow evolution down.” Continue Reading »

George C. Williams

The International Society for Evolution, Medicine and Public Health is proud to announce the launch of the George C. Williams Prize.

The $5,000 Prize will be awarded to the first author of the most significant article published in 2015 in the Society’s flagship journal, Evolution, Medicine and Public Health. Oxford University Press publishes the journal open access.  Stephen Stearns is the editor.  Author’s fees are waived for 2015. All articles published in 2015 will be automatically considered for the Prize.

The Prize recognizes the contributions of George C Williams to evolutionary medicine, and aims to encourage and highlight important research in this growing field. In a seminal 1957 paper, Williams initiated work on several problems central to medicine, including an evolutionary theory of aging and life history traits including menopause. He did important work on the problem of why sex exists.  Perhaps his most lasting contribution is his 1966 book Adaptation and Natural Selection, a critique of group selection that transformed how biologists think about the evolution of sociality.  In the 1990′s he collaborated with Randolph Nesse on a series of papers and a book that inspired much ongoing work on how evolutionary biology can help us understand disease and improve human health.

The Society’s Publications Committee, chaired by Andrew Read, will appoint the Prize Committee.  The Prize Committee will interpret the criterion of “most significant article” with attention to the focus on major unanswered questions that characterized the work of George Williams. Articles by members of the Prize Committee and their students and close colleagues are not eligible for the prize. Members of the Publications Committee and their students and close colleagues are eligible with special restrictions.

According to estimates by the World Health Organization, in 2013 on the order of 35 million people were infected with HIV worldwide (http://www.who.int/gho/hiv/en/).  Globally, about 1.5 million people are believed to have died from AIDS-related diseases in that year.  Substantial, although perhaps not insurmountable, obstacles to the development of a highly effective vaccine for HIV-1 have increased interest in curative strategies.  A key challenge to cure strategies is that infected people harbor a latent reservoir of infected CD4+ memory T cells that do not express significant amounts of viral proteins.  The paucity of viral proteins in these cells makes it more difficult to identify infected cells and eradicate them.  A new study (Deng et al., 2015) in Nature from Robert Siliciano’s lab at Johns Hopkins identifies an additional difficulty faced by one of the currently popular approaches to curative therapy but also, more optimistically, suggests a way to overcome this challenge.

Abstract:   Papillomaviruses (PVs) are a numerous family of small dsDNA viruses infecting virtually all mammals. PVs cause infections without triggering a strong immune response, and natural infection provides only limited protection against reinfection. Most PVs are part and parcel of the skin microbiota. In some cases, infections by certain PVs take diverse clinical presentations, from highly productive self-limited warts to invasive cancers. Continue Reading »

Abstract

Unsatisfactory progress in cancer medicine and prevention calls for new research approaches. Research can broaden its view of cancer to include not only specific molecular elements, but also the process that explains their origin and dynamics. This process is Darwinian evolution of somatic cells. Applicable modeling techniques are available from process-oriented systems biology. We review relevant concepts and techniques, and their application to four key open questions in cancer prevention research. Helpful concepts are transferable from classical evolutionary biology and ecology, while useful techniques include computational agent-based modeling. The research questions we review include (1) why do benign neoplasms often progress to malignancy? (2) what is the chronological sequence of molecular events in cancer progression? (3) how can we find reliable molecular biomarkers for cancer? and (4) will evolved drug resistance stymie efforts at a long-term cancer chemoprevention? We conclude that molecular analysis can be usefully augmented with process-oriented systems biology to guide empirical research into the most productive directions.

  Illness in breastfeeding infants relates to concentration of lactoferrin and secretory Immunoglobulin A in mother’s milk
By Alicia A Breakey, Katie Hinde, Claudia R Valeggia, Allison Sinofsky, and  Peter T Ellison

Evol Med Public Health published 20 January 2015, 10.1093/emph/eov002
http://emph.oxfordjournals.org/content/early/2015/01/19/emph.eov002.abstract?papetoc
We tested the relationship between infant illness and two immune factors
in milk, lactoferrin and secretory immunoglobulin A (sIgA). We found that
milk lactoferrin is positively related to symptoms of illness, suggesting
a responsive pattern, while milk sIgA is negatively related to illness,
suggesting it has a protective role. Milk lactoferrin is positively
related to symptoms of illness, while milk sIgA is negatively related to
illness among Toba infants.

  Post-term birth as a response to environmental stress: the case of September 11, 2001

The odds of post-term delivery among gestations exposed to the terrorist
attacks of September 2001 in the 33-36th week of gestation were higher
than statistically expected. This finding provides support for our
hypothesis that maternal exposure to stress late in pregnancy may result
in an adaptive response of prolonged gestation.
