DNA Valley

From Wikipedia, the free encyclopedia
https://en.wikipedia.org/wiki/DNA_Valley

DNA Valley (or DNA Alley) is a region in Maryland that serves as a biotechnology hub with a focus on genetic medicine. Roughly traced by Rockville, Frederick, and Baltimore, DNA Valley includes the innovation companies in the Maryland I-270 technology corridor, the various campuses of federal entities such as the FDA and NIH, as well as The University of Maryland, Johns Hopkins University, The Institute for Human Virology, and various laboratories with high biosafety levels such as Fort Detrick. Major DNA valley cities include: Baltimore, Columbia, Germantown, Silver Spring, Rockville, Bethesda, Gaithersburg, College Park, and Frederick. The counties that make up DNA valley are Montgomery County, Frederick County, Howard County, Baltimore County, Anne Arundel County, and Carroll County. According to the Bureau of Economic Analysis, these counties contributed a combined GDP of $310,407,270 in 2021, higher than several nations. Local business leaders like Jeff Galvin expect this figure to increase in step with the growth of the biotechnology sector.

DNA Valley is home to many of Maryland's biotechnology, pharmaceutical, and life science companies including AstraZeneca, BioNTech, GeneDx, Qiagen, American Gene Technologies, and GlaxoSmithKline. A defining feature of the region is its staggering concentration of scientists and doctors. According to New Scientist, "There are more MDs and PhDs per capita in a 10-mile radius of DC than anywhere else in the country".

Etymology

The name "DNA Valley" is championed by American Gene TechnologiesⓇ CEO, Jeff Galvin. Galvin came to Maryland and the life science industry after a successful career in Silicon Valley and immediately saw the similarities between the early days of the tech industry in Silicon Valley and the life science industry in Maryland. The earliest documented use of the name came from an article written by Alison George at New Scientist in 2004, as she recounted a cab ride where her driver referred to the D.C. area as "DNA Valley" because of the concentration of biotech companies in the area.

DNA valley is not an actual geographical valley and is instead named as such because of the similarities between the biotechnology and life science boom in Maryland and the tech boom that occurred in Silicon Valley in the 1970s and 1980s. Previous to the growth of the biotechnology industry, Maryland and the surrounding regions were predominantly focused on the seafood, agriculture, and logistics industries due to the abundant waterways available in the state.

History

Role of the NIH

The National Institute of Health (NIH) played a central role in the emergence of DNA Valley, through its role in the Human Genome project, its central location in Bethesda, Maryland, and its investment into life sciences in the local area.

The National Institutes of Health (NIH) have played a major role in the development of the life science industry boom in Maryland, and thus the creation of DNA Valley. The NIH originally moved its headquarters from the Old Naval Observatory to Bethesda, Maryland in 1938. In 1989, as part of the launch of the Human Genome Project, the National Center for Human Genome Research (now known as The National Human Genome Research Institute) was founded in Bethesda.[11] This made Bethesda the national hub for genetic research as genetic researchers from around the country came to help sequence the human genome.[12] This project, being one of the most influential scientific projects of the last century, planted the seeds for the eventual biotechnology hub that has formed in the area since. The infrastructure and attention to the industry that the NCHGR and the HGP brought to Maryland are what opened the door to the extensive cell and gene therapy industries that Maryland and DNA Valley are now home to.

The NHGRI is not the only NIH subsidiary that has led to DNA Valley becoming such a major life science hub. The NIH as a whole has fueled the biotech industry in Maryland as the research done at the federally funded facilities has resulted in new fields of research, new tools, and highly trained researchers that often remain in the area and create their own life science companies. For example, the work done by Roscoe Brady, MD, PhD on viral vectors caught the attention of entrepreneur Jeff Galvin, inspiring him to found American Gene Technologies and pursue potential cures for diseases like HIV, PKU, and certain cancers.. The NIH also funds outside research in the area, which further allows for the industry to flourish as more companies want to be based near the NIH headquarters in Bethesda.

A variety of life science-related conferences are held annually at the NIH headquarters in Bethesda, such as workshops, trainings, and professional conferences, all of which not only bring attention and prestige to the life science industry in Maryland, but also result in a better trained and educated population in the area, allowing for the further success of the industry.

The NIH is not exclusively located in Bethesda and has a variety of campuses in Maryland. The Bayview Campus in Baltimore contains the research programs of the National Institute of Aging and the National Institute of Drug Abuse. The Frederick National Laboratory and Riverside Research Park are home to the National Cancer Institute, which includes the Center for Cancer Research. The widespread footprint of the NIH in Maryland directly correlates to the biotech boom that resulted in DNA Valley, as the highest concentrations of life science companies are located in the same locations of Rockville, Frederick, and Baltimore.

Rise of genetic medicine

Scientists R. Michael Blaese, W. French Anderson, and Kenneth Culver at the press conference that announced the start of the first ever gene therapy trial for severe combined immunodeficiency (SCID) in 1990.

The first speculation about the plausibility of introducing DNA sequences into patient's cells to cure diseases occurred in the 1960s. Then in 1972, Theodore Friedman and Richard Roblin published a paper in Science named "Gene Therapy for Human Genetic Diseases?", which detailed the possibility of inserting unmutated or healthy DNA to cure patients with genetic diseases. However, this paper also urged that the technology be furthered with caution as a result of the lack of understanding of the technology and its potential effects. They were primarily worried about the lack of knowledge about genetic recombination and gene regulation, lack of understanding about the relationship between genetic mutations and diseases, and the lack of understanding of the potential side effects of gene therapy.

For 18 years after that paper was published, further research was conducted to help limit the risks detailed by Theodore Friedman and Richard Roblin. Then in 1990, the first successful gene therapy trial was launched. A four-year-old girl named Ashanthi De Silva with severe combined immunodeficiency (SCID) was treated with gene therapy. Ashanthi was lacking the enzyme adenosine deaminase (ADA), which caused her T-cells to die, leaving her with little to no protection against infection. To treat this, Dr. W. French Anderson from the National Heart, Lung, and Blood Institute in Bethesda, Maryland, delivered the correct ADA gene, using a disabled virus, to white blood cells that had been removed from her body, and then injected the cells back into her body.

The rise of gene therapy was not easy as it suffered a major setback in 1999 with the trials at the University of Pennsylvania. During the trials, an 18-year-old named Jesse Gelsinger who had the genetic disease ornithine transcarbamylase deficiency, died from an immune response after being treated with a working gene carried by an adenovirus.

The early 2010s brought back the evolution of gene therapy as a potential cure to many different diseases. New delivery methods for the gene therapies were discovered, thus making the techniques significantly safer. Researchers also added enhancers and promoters, which allowed for better control of the gene as they could decide when and where it would be turned on and to what extent. These discoveries, along with others made during this period, allowed gene therapy to regain its momentum and move to the forefront of Medical Technology development. There was then a wave of approvals for gene therapy techniques from 2003 to 2012, including therapies for cancer, artery disease, and others. Since then, the rate of development and approval of gene therapies has increased, with the FDA expecting to approve between 10 and 20 gene therapies each year until 2025.

Economy

The D.C. / Maryland area has the second-highest rated life science hub in the United States, with Maryland alone providing 44,260 jobs in life science. Maryland life science businesses generated over $18.6 billion in 2018, paid over $4.9 billion in wages, with an average salary of $110,690. Maryland also boasted the 5th highest concentration of doctoral scientists and engineers and the highest STEM concentration in the country in 2022. Between 2017 and 2022, the life science research jobs increased by 19%, which was larger than the national growth rate of 16%, indicating a particular focus on the industry in Maryland.

The region has more than double the amount of federal research labs than any other state, partly due to the presence of the NIH headquarters in Bethesda, Maryland. Maryland also has the 11th lowest unemployment rate at 2.5% in 2023, which is partly a result of the booming biotech and life science industry in the area.

Housing

Maryland, and by association DNA Valley, has a severe affordable housing shortage, with only approximately 30 affordable and available rental units for every 100 extremely low income families and a total housing shortage of 120,000 units. This is possibly due to the boom in life science jobs in the area, while the creation of housing units has remained constant, leading to the imbalance. DNA Valley also includes some of the highest cost of living areas in the country, with D.C. having the second highest and Maryland having the sixth highest.

Demographics

Depending on what geographic regions (particularly parts of Washington, D.C.) are included in the meaning of the term, the population of DNA Valley is between 2 million and 3.5 million. According to the U.S. Census Bureau, almost a third of DNA Valley's population is Black or of African descent, 11% are of Hispanic descent and 6.9% is of Asian descent.

Diversity

DNA Valley is one of the most diverse areas in the country, with 3 of the 10 most diverse communities in the area, those being Gaithersburg, Germantown, and Silver Spring. Biotechnology as a whole is not a typically diverse field, being overwhelmingly dominated by white (56%) and Asian (21%) employees. Even greater disparity is seen among executives, with 72% of execs being White and 15% being Asian. The biotech hub in DNA Valley tends to differ from this norm, likely due to the diversity of the area.

Gender

Similarly to race, gender disparity is quite significant in the field of biotechnology, with males dominating the space, particularly in positions of power. 66% of executives and 79% of CEOs are men. DNA Valley follows this trend, as in 2021, women only made up around 22% of the executive positions at biotechnology companies. One possible explanation for this, as proposed by Harvard Senior Research Associate Vivek Wadhwa, is that parents tend to not encourage their daughters to pursue a career in science and engineering as much as they would with their sons. Wadhwa also cites the lack of potential role models for women in the science and engineering fields in comparison to men.

However, interestingly, Maryland has the highest average salary for female CEOS, at around $280,000, which may be in part due to the higher average salaries in Maryland in general. Washington D.C. also has the second-highest female CEO percentage in the country at 47.5%, which would change the DNA Valley numbers depending on whether you include D.C. in the geographical boundaries of the region. There have been concerted efforts to fix the current lack of females in Maryland life science fields, including the founding of a Women in Bio (WIB) chapter in the D.C. region in 2011. The focus of this chapter is to promote diversity and inclusion for all women in life science-related fields. WIB also sponsors the Herstory Gala, in Rockville, Maryland every year to celebrate the women trailblazers in life sciences that have had an impact on the field in the DNA Valley area.

Statistics

Maryland, and thus DNA Valley, is considered one of the most diverse states in the country, based both on religious and ethnic group diversity. DNA Valley's population is made up of 32% Black, 7% Asian, 12% Hispanic or Latino, and 1% Native American people. In terms of religious affiliations, DNA Valley's population is divided into 69% Christian-based faiths (mostly made up of equal percentages of Evangelical Protestant, Mainline Protestant, Historically Black Protestant, and Catholic), 23% not affiliated with any faith, and 8% having non-Christian-based faiths, primarily made up of Jewish, Muslim, Buddhist, and Hindu faiths

Education

The funding for public schools in DNA Valley varies drastically depending on the area as a result of increased grants from private foundations in wealthier areas such as Montgomery County and particularly Bethesda. Less wealthy areas such as Garret County rely on state funding.

Hugo Marie de Vries (Dutch: [ˈɦyɣoː ˈvris]; 16 February 1848 – 21 May 1935) was a Dutch botanist and one of the first geneticists. He is known chiefly for suggesting the concept of genes, rediscovering the laws of heredity in the 1890s while apparently unaware of Gregor Mendel's work, for introducing the term "mutation", and for developing a mutation theory of evolution.

Early life

De Vries was born in 1848, the eldest son of Gerrit de Vries (1818–1900), a lawyer and deacon in the Mennonite congregation in Haarlem and later Prime Minister of the Netherlands from 1872 until 1874, and Maria Everardina Reuvens (1823–1914), daughter of a professor in archaeology at Leiden University. His father became a member of the Dutch Council of State in 1862 and moved his family over to The Hague. From an early age Hugo showed much interest in botany, winning several prizes for his herbariums while attending gymnasium in Haarlem and The Hague.

In 1866 he enrolled at the Leiden University to major in botany. He enthusiastically took part in W.F.R. Suringar's classes and excursions, but was mostly drawn to the experimental botany outlined in Julius von Sachs' 'Lehrbuch der Botanik' from 1868. He was also deeply impressed by Charles Darwin's evolution theory, despite Suringar's skepticism. He wrote a dissertation on the effect of heat on plant roots, including several statements by Darwin to provoke his professor, and graduated in 1870.

Early career

After a short period of teaching, de Vries left in September 1870 to take classes in chemistry and physics at the Heidelberg University and work in the laboratory of Wilhelm Hofmeister. In the second semester of that school year he joined the lab of the esteemed Julius Sachs in Würzburg to study plant growth. From September 1871 until 1875 he taught botany, zoology and geology at schools in Amsterdam. During each vacation he returned to the lab in Heidelberg to continue his research.

In 1875, the Prussian Ministry of Agriculture offered de Vries a position as professor at the still to be constructed Landwirtschaftliche Hochschule ("Royal Agricultural College") in Berlin. In anticipation, he moved back to Würzburg, where he studied agricultural crops and collaborated with Sachs. By 1877, Berlin's College was still only a plan, and he briefly took up a position teaching at the University of Halle-Wittenberg. The same year he was offered a position as lecturer in plant physiology at the newly founded University of Amsterdam. He was made adjunct professor in 1878 and full professor on his birthday in 1881, partly to keep him from moving to the Berlin College, which finally opened that year. De Vries was also professor and director of Amsterdam's Botanical Institute and Garden from 1885 to 1918.

Definition of the gene

In 1889, de Vries published his book Intracellular Pangenesis, in which, based on a modified version of Charles Darwin's theory of Pangenesis of 1868, he postulated that different characters have different hereditary carriers. He specifically postulated that inheritance of specific traits in organisms comes in particles. He called these units pangenes, a term 20 years later to be shortened to genes by Wilhelm Johannsen.

Rediscovery of genetics

Hugo de Vries in the 1890s

To support his theory of pangenes, which was not widely noticed at the time, de Vries conducted a series of experiments hybridising varieties of multiple plant species in the 1890s. Unaware of Mendel's work, de Vries used the laws of dominance and recessiveness, segregation, and independent assortment to explain the 3:1 ratio of phenotypes in the second generation. His observations also confirmed his hypothesis that inheritance of specific traits in organisms comes in particles.

He further speculated that genes could cross the species barrier, with the same gene being responsible for hairiness in two different species of flower. Although generally true in a sense (orthologous genes, inherited from a common ancestor of both species, tend to stay responsible for similar phenotypes), de Vries meant a physical cross between species. This actually also happens, though very rarely in higher organisms (see horizontal gene transfer). De Vries' work on genetics inspired the research of Jantina Tammes, who worked with him for a period in 1898.

In the late 1890s, de Vries became aware of Mendel's obscure paper of thirty years earlier and he altered some of his terminology to match. When he published the results of his experiments in the French journal Comptes rendus de l'Académie des Sciences in 1900, he neglected to mention Mendel's work, but after criticism by Carl Correns he conceded Mendel's priority.

Correns and Erich von Tschermak now share credit for the rediscovery of Mendel's laws. Correns was a student of Nägeli, a renowned botanist with whom Mendel corresponded about his work with peas but who failed to understand its significance, while, coincidentally, Tschermak's grandfather taught Mendel botany during his student days in Vienna.

Mutation theory

In his own time, de Vries was best known for his mutation theory. In 1886, he had discovered new forms among a group of Oenothera lamarckiana, a species of evening primrose, growing wild in an abandoned potato field near Hilversum, having escaped a nearby garden. Taking seeds from these, he found that they produced many new varieties in his experimental gardens; he introduced the term mutations for these suddenly appearing variations. In his two-volume publication The Mutation Theory (1900–1903) he postulated that evolution, especially the origin of species, might occur more frequently with such large-scale changes than via Darwinian gradualism, basically suggesting a form of saltationism. De Vries's theory was one of the chief contenders for the explanation of how evolution worked, leading, for example, Thomas Hunt Morgan to study mutations in the fruit fly, until the modern evolutionary synthesis became the dominant model in the 1930s. During the early decades of the twentieth century, de Vries' theory was enormously influential and continued to fascinate non-biologists long after the scientific community had abandoned much of it (while retaining the idea of mutations as a crucial source of natural variation). The large-scale primrose variations turned out to be the result of various chromosomal abnormalities, including ring chromosomes, balanced lethals and chromosome duplications (polyploidy), while the term mutation now generally is restricted to discrete changes in the DNA sequence. However, the popular understanding of "mutation" as a sudden leap to a new species has remained a staple theme of science fiction, e.g. the X-Men movies (and the comic books that preceded them).

In a published lecture of 1903 (Befruchtung und Bastardierung, Veit, Leipzig), De Vries was also the first to suggest the occurrence of recombinations between homologous chromosomes, now known as chromosomal crossovers, within a year after chromosomes were implicated in Mendelian inheritance by Walter Sutton.

Botanist Daniel Trembly MacDougal attended his lectures in United States on Mutation Theory. In 1905 he helped published these lectures into a book Species and Varieties: Their Origin by Mutation.

Honors and retirement

Hugo de Vries at his retirement (Thérèse Schwartze, 1918)

In 1878 de Vries became member of the Royal Netherlands Academy of Arts and Sciences. He was elected to the American Philosophical Society in 1903 and the United States National Academy of Sciences in 1904. In May 1905, de Vries was elected Foreign Member of the Royal Society. In 1910, he was elected a member of the Royal Swedish Academy of Sciences. In 1921, he was elected to the American Academy of Arts and Sciences. He was awarded the Darwin Medal in 1906 and the Linnean Medal in 1929.

He retired in 1918 from the University of Amsterdam and withdrew to his estate De Boeckhorst in Lunteren where he had large experimental gardens. He continued his studies with new forms until his death in 1935.
