Building the Safe Genes Toolkit

DARPA created the Safe Genes program to gain a fundamental understanding of how gene editing technologies function; devise means to safely, responsibly, and predictably harness them for beneficial ends; and address potential health and security concerns related to their accidental or intentional misuse. Today, DARPA announced awards to seven teams that will pursue that mission, led by: The Broad Institute of MIT and Harvard; Harvard Medical School; Massachusetts General Hospital; Massachusetts Institute of Technology; North Carolina State University; University of California, Berkeley; and University of California, Riverside. DARPA plans to invest $65 million in Safe Genes over the next four years as these teams work to collect empirical data and develop a suite of versatile tools that can be applied independently or in combination to support bio-innovation and combat bio-threats.

Gene editing technologies have captured increasing attention from healthcare professionals, policymakers, and community leaders in recent years for their potential to selectively disable cancerous cells in the body, control populations of disease-spreading mosquitos, and defend native flora and fauna against invasive species, among other uses. The potential national security applications and implications of these technologies are equally profound, including protection of troops against infectious disease, mitigation of threats posed by irresponsible or nefarious use of biological technologies, and enhanced development of new resources derived from synthetic biology, such as novel chemicals, materials, and coatings with useful, unique properties.

Achieving such ambitious goals, however, will require more complete knowledge about how gene editors, and derivative technologies including gene drives, function at various physical and temporal scales under different environmental conditions, across multiple generations of an organism. In parallel, demonstrating the ability to precisely control gene edits, turning them on and off under certain conditions or even reversing their effects entirely, will be paramount to translation of these tools to practical applications. By establishing empirical foundations and removing lingering unknowns through laboratory-based demonstrations, the Safe Genes teams will work to substantially minimize the risks inherent in such powerful tools.

A New Technique Transforms Human Skin Into Brain Cells

“Microglia play an important role in Alzheimer’s and other diseases of the central nervous system. Recent research has revealed that newly discovered Alzheimer’s-risk genes influence microglia behavior,” Jones said in an interview for a UCI press release. “Using these cells, we can understand the biology of these genes and test potential new therapies.”

A Renewable Method

The skin cells had been donated by patients from UCI’s Alzheimer’s Disease Research Center. These were first subjected to a genetic process to convert them into induced pluripotent stem (iPS) cells — adult cells modified to behave as an embryonic stem cell, allowing them to become other kinds of cells. These iPS cells were then exposed to differentiation factors designed to imitate the environment of developing microglia, which transformed them into the brain cells.

Epigenetics between the generations: Researchers prove that we inherit more than just genes

We are more than the sum of our genes. Epigenetic mechanisms modulated by environmental cues such as diet, disease or lifestyle take a major role in regulating the DNA by switching genes on and off. It has been long debated if epigenetic modifications accumulated throughout the entire life can cross the border of generations and be inherited to children or even grand children. Now researchers from the Max Planck Institute of Immunobiology and Epigenetics in Freiburg show robust evidence that not only the inherited DNA itself but also the inherited epigenetic instructions contribute in regulating gene expression in the offspring. Moreover, the new insights by the Lab of Nicola Iovino describe for the first time biological consequences of this inherited information. The study proves that mother’s epigenetic memory is essential for the development and survival of the new generation.

Humans have than 250 different cell types. They all contain the exact same DNA bases in exactly the same order; however, liver or nerve cells look very different and have different skills. What makes the difference is a process called epigenetics. Epigenetic modifications label specific regions of the DNA to attract or keep away proteins that activate genes. Thus, these modifications create, step by step, the typical patterns of active and inactive DNA sequences for each cell type. Moreover, contrary to the fixed sequence of ‘letters’ in DNA, can also change throughout life and in responses to environment or lifestyle. For example, smoking changes the epigenetic makeup of lung cells, eventually leading to cancer. Other influences of external stimuli like stress, disease or diet are also supposed to be stored in the of cells.

It has long been thought that these epigenetic modifications never cross the border of generations. Scientists assumed that epigenetic memory accumulated throughout life is entirely cleared during the development of sperms and egg cells. Just recently a handful of studies stirred the scientific community by showing that epigenetic marks indeed can be transmitted over generations, but exactly how, and what effects these genetic modifications have in the offspring is not yet understood. “We saw indications of intergenerational inheritance of epigenetic information since the rise of the epigenetics in the early nineties. For instance, epidemiological studies revealed a striking correlation between the food supply of grandfathers and an increased risk of diabetes and cardiovascular disease in their grandchildren.

Biosensors could give soldiers superhuman fighting abilities

According to the report, the US Air Force, Marine Corps, Navy and other special forces are looking to improve troops’ performance by looking at their bodies at a genetic level (stock)

Earlier this year the AirForce successfully tested a helmet that can monitor brain activity and tell if the pilot is feeling stressed or panicked.

One research project is using a laptop-camera lens to find out if a person’s haemoglobin is oxygenated. This can then be used to work out a person’s heart rate.

Does the Fountain of Youth really exist?

Previously he said 10 years and that was 2016 where he said 2 years until phase 1 human trials.

Is it an impossible dream to find Ponce de Leon’s Fountain of Youth? No! I’ve just attended my 67th reunion at The Harvard Medical School (HMS) and, while interviewing Dr. George Church, I discovered it is no longer science fiction.

Dr. Church, Professor of Genetics at HMS, one of the world’s great scientists, predicts we are about to end the aging process. In the next five years no less! That’s why I say — damn it! I was born too soon.

Is Church too optimistic? Maybe, but when you see his 6-foot 5 inch body towering over you, with his white beard, it’s like talking to Charles Darwin or even Jesus Christ.

This Is How Gene-Editing Will Change The Food You Eat

For example, in 1994 Calgene won approval to sell the Flavr Savr tomato. To make a Flavr Savr, scientists genetically modified a garden variety tomato with aminoglycoside 3-phosphotransferase II, a compound that kept the fruit from rotting.

The tinkering sabotaged the process that makes tomatoes turn squishy. But the less-squishy tomatoes never did catch on with a skeptical public. The company was later sold to Monsanto.

It changed everything.

With CRISPR, scientists can literally edit organisms, removing the bits that lead to unfavorable outcomes.

Ethicists worry about a rush toward designer babies. And there have been some disturbing developments on that end in China. However, the real opportunity in the near term has always been agriculture.

Synthetic Biology and the Future of Creation

For decades, biologists have read and edited DNA, the code of life. Revolutionary developments are giving scientists the power to write it. Instead of tinkering with existing life forms, synthetic biologists may be on the verge of writing the DNA of a living organism from scratch. In the next decade, according to some, we may even see the first synthetic human genome. Join a distinguished group of synthetic biologists, geneticists and bioengineers who are edging closer to breathing life into matter.

Revita Life Sciences Continues to Advance Multi-Modality Protocol in Attempt to Revive Brain Dead Subjects

Rudrapur, Uttrakhand, India — July 02, 2017

Revita Life Sciences, (http://revitalife.co.in) a biotechnology company focused on translational regenerative therapeutic applications, has announced that it is continuing to advance their novel, multi-modality clinical intervention in the state of brain death in humans.

“We have proactively continued to advance our multi-modality protocol, as an extended treatment before extubation, in an attempt to reverse the state of brain death” said Mr.Pranjal Agrawal, CEO Revita Life Sciences. “This treatment approach has yielded some very encouraging initial outcome signs, ranging from minor observations on blood pressure changes with response to painful stimuli, to eye opening and finger movements, with corresponding transient to permanent reversal changes in EEG patterns.”

This first exploratory study, entitled “Non-randomized, Open-labelled, Interventional, Single Group, and Proof of Concept Study with Multi-modality Approach in Cases of Brain Death Due to Traumatic Brain Injury Having Diffuse Axonal Injury” is ongoing at Anupam Hospital, Rudrapur, Uttrakhand. The intervention primarily involves intrathecal administration of minimal manipulated (processed at point of care) autologous stem cells derived from patient’s fat and bone marrow twice a week.

This study was inappropriately removed from the Indian Council of Medical Research (ICMR) database. ICMR has no regulatory oversight on such research in India.

The Central Drugs Standard Control Organization (CDSCO), Drug Controller General of India, had no objection to the program progressing. Regulatory approval as needed for new drugs, is currently not required when research is conducted on the recently deceased, although IRB and family consent is definitely required. CDSCO, the regulator of such studies, clearly states that “no regulatory requirements are needed for any study with minimal manipulated autologous stem cells in brain death subjects”.

Death is defined as the termination of all biological functions that sustain a living organism. Brain death, the complete and irreversible loss of brain function (including involuntary activity necessary to sustain life) as defined in the 1968 report of the Ad Hoc Committee of the Harvard Medical School, is the legal definition of human death in most countries around the world. Either directly through trauma, or indirectly through secondary disease indications, brain death is the final pathological state that over 60 million people globally transfer through each year.

“We are in process of publishing our initial retrospective results, as well ongoing early results, in a peer reviewed journal. These initial findings will prove invaluable to the future evolution of the program, as well as in progressing the development multi-modality regenerative therapeutics for the full range of the severe disorders of consciousness, including coma, PVS, the minimally conscious state, and a range of other degenerative CNS conditions in humans,” said Dr. Himanshu Bansal, Chief Scientific Officer, Revita Life Sciences and Director of Mother Cell.

With the maturation of the tools of medical science in the 21st century, especially cell therapies and regenerative medicines, tissues once considered irretrievable, may finally be able to be revived or rejuvenated. Hence many scientists believe that brain death, as presently defined, may one day be reversed. While the very long term goal is to find a solution for “re-infusing life”, the short term purpose of these types of studies is much less dramatic, which is to confirm if the current definition of brain irreversibility still holds true. There have been many anecdotal reports of brain death reversal across the world over the past decades in the scientific literature. Studies of this nature serve to verify and establish this very fact in a scientific and controlled manner. It will also one day give a fair chance to individuals, who are declared brain dead, especially after trauma.
