Horrifying Discovery: Scientists Find That DNA Mutations Are More Common Than Previously Thought – SciTechDaily

Posted: May 17, 2022 at 7:29 pm

Researchers at EMBL Heidelberg found that inversions in the human genome are more common than previously thought, which impacts our understanding of certain genetic diseases.

Our DNA serves as a blueprint for the cellular machinery that allows cells, organs, and even whole organisms to work. However, mutations in our DNA can cause genetic illnesses. Point mutations at a single site, as well as deletions, duplications, and inversions, are examples of such DNA mutations.

Inversion refers to a piece of DNA inverting its orientation in the genome. Because inversions are more difficult to analyze than other forms of mutations, they are poorly understood. Scientists from EMBL Heidelberg, working with colleagues from the University of Washington in the United States and Heinrich Heine University Dsseldorf in Germany, have determined that inversions are one of the most common mutational processes in humans.

The researchers uncovered how inversions are formed and investigated in detail a set of 40 inversions that form recurrently in the genome, where the DNA sequence flips back and forth. These flip-flopping inversions typically lie in regions linked to the development of certain human diseases called genomic disorders.

We found that inversions form at a much higher rate than previously thought. In humans, at least 0.6% of the genome repeatedly changes direction, making inversion one of the fastest mutational processes in humans, said Jan Korbel, EMBL Senior Scientist and Head of Data Science. At these sites, the genome is not stable the direction of the DNA code continues to switch back and forth.

These unstable areas are home to the many essential human genes. Scientific studies of long-distance gene regulation or epigenetics must now take into account this flipping behavior of genomic regions.

Inversions are also relevant for the development of human diseases, such as developmental delays in children or neuropsychiatric disorders in adults. Despite their importance, these regions have been very difficult to study before because of their complexity. Showing that these inversions indeed flip-flop back and forth required a new set of computational methods, said Tobias Marschall, Director of the Institute of Medical Biometry and Bioinformatics and the Heinrich Heine University Dsseldorf. We can now provide human geneticists with a new tool to understand the origin of disease in their patients.

Evan Eichler, group leader at the University of Washington, said: We showed for the first time that inversions can be associated with rare genomic rearrangements found in pediatric autism, developmental delay, and epilepsy. The question now is why? We hypothesize that certain configurations at the flanks of the inversions either predispose or protect individuals and their offspring from disease-associated rearrangements. This could have a practical application in the clinic, where it could be used to identify families at risk for developing these disorders.

Excision BioTherapeutics

SAN FRANCISCO, May 17, 2022 (GLOBE NEWSWIRE) -- Excision BioTherapeutics Inc., a biotechnology company developing CRISPR-based therapies intended to cure viral infectious diseases, today announced that preclinical and bioinformatic data showing robust and specific editing of HIV proviral DNA with EBT-101 will be featured in an upcoming poster presentation at the American Society of Gene & Cell Therapy (ASGCT) 25th Annual Meeting, which is taking place at the Walter E. Washington Convention Center in Washington, D.C.

EBT-101 is a unique, clinical-stage, in vivo CRISPR-based therapeutic designed to functionally cure HIV infections after a single intravenous infusion. It employs an adeno-associated virus (AAV) to deliver CRISPR-Cas9 and dual guide RNAs targeting three sites within the HIV genome. Bioinformatic analyses featured in the ASGCT poster compare these EBT-101 target sites against the human reference genome and show no identical matches. Moreover, there are no candidate off-target sites in the human reference genome with only one or two differences from EBT-101 target sites, and only a single candidate off-target site with three differences. These findings predict a lack of off-target activity for EBT-101, which has been confirmed by in vitro and in vivo studies showing HIV excision without unintended editing.

Taken together, the data being presented at ASGCT highlight the key advantages of Excisions novel therapeutic approach, said TJ Cradick, Ph.D., Chief Scientific Officer of Excision and lead author on the poster. By leveraging our in-silico design platform, we carefully crafted EBT-101 to minimize viral escape and off-target effects by cutting at three target sites that are specific to the HIV genome. Latent viral reservoirs were eradicated in in multiple disease models and resulted in functional cures in transgenic mice. We are now working to build on these results through the advancement of EBT-101s recently initiated Phase 1/2 clinical trial, and look forward to discussing our program with the scientific community at the upcoming ASGCT meeting.

Story continues

The ASGCT poster, entitled, EBT-101 achieves robust CRISPR-based editing of HIV proviral DNA without detectable off-target effects, will be presented today from 5:30 6:30 PM ET during the Hematologic and Immunologic Disease II poster session (Board No. TU-205). The poster was authored in collaboration with researchers from institutions including Temple University and Dartmouth-Hitchcock Medical Center. A copy of the poster will be posted to the Excisions website following its presentation at the meeting.

Startup Genome and the Ministry of the Economy Launch a Study to Assess and Benchmark the Luxembourg Star – Benzinga

Posted: at 7:29 pm

SAN FRANCISCO - May 16, 2022 - (

)

The Ministry of the Economy launches a strategic initiative aimed at assessing the Luxembourg start-up ecosystem in order to identify further steps to bring the ecosystem towards a next level of development over the upcoming years.

The Luxembourg start-up ecosystem has been on a constant rise over the past decade. In its latest mapping (www.startupluxembourg.com/why-luxembourg/ecosystem-mapping), Luxinnovation, the Luxembourg's national innovation agency, identified more than 500 start-ups active in developing and offering innovative digital and data driven solutions, mostly in the key fields of economic diversification.

Luxembourg has an established history of empowering innovators, entrepreneurs, and investors to implement their vision and contribute to economic diversity through regional and globally competitive enterprises.Given Luxembourg's central position in the European single market, highly advanced legislative and regulatory frameworks and competitive digital infrastructure, the start-up ecosystem attracts innovative professionals and start-up companies from all over the world.

In order to gain a more granular view of the Luxembourg start-up ecosystem and its international positioning, an assessment and a benchmarking will start in May. This assessment and benchmarking will provide a thorough qualitative and quantitative understanding of the Luxembourg start-up ecosystem, based on data analysis, information gathered from the start-up community and interviews with key stakeholders. The study will provide relevant comparisons with international peers, highlighting potential future development opportunities as well as ecosystem success factor strengths and gaps.

Startup Genome, a leading research and policy advisory organization specialized in the analysis of start-up ecosystems was chosen to carry out this assessment and benchmarking in close collaboration with the dedicated team at the Ministry of the Economy and at Luxinnovation. In this process, Startup Genome will leverage its experience of over 200 ecosystems worldwide and the knowledge and data gathered through its yearlyGlobal Startup Ecosystem Report (GSER).

Within the context of the study and in order to collect the feedback from the start-up community, Startup Genome will reach out to entrepreneurs with a dedicated survey. Start-ups and entrepreneurs willing to take the survey and give their input can find more information on http://www.startupluxembourg.com.

The results of the study as well as a consultation process with key stakeholders of the ecosystem will be taken into account for the elaboration of a strategic roadmap for the further development of the Luxembourg start-up ecosystem.

Indore: Even after being the worst hit by Covid-19, no end to Indores wait for a genome sequencing machine – Free Press Journal

Posted: at 7:29 pm

Indore (Madhya Pradesh)

Even after being the worst hit by Covid-19, Indore will have to wait for more to get the genome sequencing machine as the government has decided to get the machine installed in Hamidia Hospital, Bhopal first.

The decision has surprised the city officials as Bhopal already has the facility of genome sequencing at the All India Institute of Medical Sciences (AIIMS).At present, samples of Covid-19 patients in Indore are being sent to National Centre for Disease Control (NCDC), Delhi and AIIMS, Bhopal for genome sequencing to know about the variant of the prevalent coronavirus.

The Centre has allotted five genome-sequencing machines to the state in December 2021 on the ground that the samples collected in Madhya Pradesh for Covid testing were sent to Delhi for genome sequencing, and it took 10 to 15 days to get reports.

These five machines were to be installed in Bhopal, Indore, Jabalpur, Rewa and Gwalior cities. These machines considerably help shorten the detection time of variants.

MGM Medical College was supposed to deposit the funds for the machine but it couldnt be done due to lack of funds. Now, the machine will be installed in Hamidia Hospital and MGM Medical College, Indore will have to wait for more for the machine, sources said.

However, the MGM Medical College administration believes to get the machine in the next phase.

We have also applied with the government for the genome sequencing machine to be installed in MGM Medical College. We believe that we will get the machine soon, Dean of MGM Medical College Dr Sanjay Dixit said.

Indore was the worst hit by Covid-19 but gets variant reports in 15-20 days

Indore was the worst hit by Covid-19 and adds the highest number of cases in the states tally.

As many as 207951 cases were found positive in the city and as many as 1461 patients lost their lives. As many as nine cases of Omicron were also tested positive in Indore but the samples were tested by a private laboratory.

On the trail of the origins of Covid-19 – The Conversation

Posted: at 7:29 pm

As the Covid-19 virus (coronavirus SARS-CoV-2) continues to spread and claim victims worldwide, its origins remain unknown. Each scientific community puts forward its own theory, with some suggesting the virus may have leaked out of a laboratory.

Another theory, based on recent studies of the Wuhan wet market in China, along with others carried out in Cambodia, Laos, Japan, China, and Thailand, posits that an ancestral virus in rhinolophus bats went on from infecting wild and/or domestic animals to humans. Indeed, in these different studies, several viruses with genetic sequences very similar to SARS-CoV-2 were isolated in these bats.

Though it has been shown some bat species have hosted these coronaviruses naturally, the wild or domestic animal (or animals) that acted as a bridge between them and humans the missing link remains unidentified. Pangolins were first suspected, but now appear to have been collateral victims rather than one of these much-talked-about missing links. A coronavirus genome sequence detected in pangolins was indeed related to that of SARS-CoV-2, but the rest of the genome was too distant from it genetically to back the hypothesis.

Moreover, the pangolins hosts in which the viruses that were genetically close to SARS-CoV-2 were found had mostly been confiscated at live-animal markets, at the end of the supply chain. As a result, they had been in lengthy contact with other animal species. It is very likely they were infected along this supply chain rather than in their natural environment. Mink farms were also suspected of being an intermediate host in China.

Lastly, pangolins and rhinolophus bats do not share the same habitat, making it highly unlikely there was any contact between the two species in which the virus jumped from one to the other. On the other hand, civets and raccoon dogs could be an intermediate source of SARS-CoV-1). Rodents or primates could also carry pathogens with zoonotic potential, such as hantaviruses which can cause haemorrhagic fever with renal syndrome or filoviruses, which include the Ebola virus. The latter is passed on to humans through wild animals, in particular bats, antelopes, and primates such as chimpanzees and gorillas, then spreads among humans, mainly by direct contact with blood, secretions and other bodily fluids from infected people. The average case fatality rate is around 50%.

In 2013, initial cases of disease from the Ebola virus were detected in West Africa. The rise of these cases led to over 10,000 deaths, mainly in Guinea, Liberia, and Sierra Leone.

Activities such as hunting, animal-handling or eating meat from wild animals therefore create the conditions for viruses to spread from animals to humans a potentially devastating phenomenon called spillover.

The ZooCov project has sought to define and quantify this risk in Cambodia. For almost two years and right from the start of the pandemic it has adopted a One Health approach to explore whether and how pathogens such as coronaviruses can be passed on to humans from wild animals that are hunted and eaten.

Indeed, in South-East Asia, wild animals are regularly traded, and bushmeat is customarily eaten. This eating habit is often opportunistic. In some communities, it complements a low-protein diet. It can also be frequent and targeted. In Cambodia, 77% of 107 families interviewed in the ZooCov project said they had eaten bushmeat in the past month.

Use for medicinal purposes is also widespread. In Vietnam, an analysis of records of the Vietnamese authorities confiscating pangolins and related by-products between 2016 and 2020 reported 1,342 live pangolins (6,330 kg), 759 dead pangolins or pangolin carcasses (3,305 kg), and 43,902 kg of pangolin scales.

Yet this consumption also has a cultural and social dimension that is still not properly understood. Among the well-off and often in big cities people sometimes eat bushmeat out of a desire for social status, and a belief that eating it endows them with the physical or physiological attributes of the animal. They also sometimes eat bushmeat out of rejection of industrially produced meat, considered unhealthy. Animals are widely reared to meet this demand and the demand for fur production.

In the Stung Treng and Mondolkiri provinces of Cambodia, where protected forest areas remain, researchers surveyed more than 900 people living on the edge of these forests to determine the structure of the illegal bushmeat trade. Statistical analyses are underway to identify the people most at risk of contact with wildlife thus with such pathogens. We already know those exposed are mostly young middle-class men, and that some communities are more exposed than others. Sociological studies have also helped better grasp todays context: the legal framework, the profiles of players in the trade, their motives and deterrents in trade and consumption of wild animals, and how the context has changed with each different health crisis (bird flu, Ebola, SARS-CoV-1, etc.).

These successive crises seem to have scarcely affected the habits of these communities. Beyond regularly eating bushmeat, one fourth of the families surveyed said they still hunted or ensnared wild animals, and 11% claimed to sell bushmeat or wild animals. Furthermore, in the same areas of study, over 2,000 samples taken from wild animals trafficked or eaten for subsistence bats, rodents, turtles, monkeys, birds, wild pigs, etc. were analysed. Some of these samples tested positive for coronaviruses and scientists at the Institut Pasteur du Cambodge (IPC) are currently sequencing their genome in a bid to learn more about their origin, evolution, and zoonotic potential. Finally, researchers collected blood samples from over 900 people from the same region to find out whether they had been in contact with a coronavirus or coronaviruses. These analyses are still underway, but what we do know is that these people had not been exposed to SARS-CoV-2 when the survey was conducted.

If the Covid crisis has taught us anything, it is the importance of detecting such emergences early in order to nip the pathogens in the bud. While many questions remain about the way cases emerge, there are just as many questions about the monitoring systems that should be set up to track them. The results of the ZooCov project will be used to develop a system for detecting spillover of zoonotic viruses early, particularly by strengthening the system for monitoring wildlife health that is already in operation in Cambodia, which was set up by the Wildlife Conservation Society (WCS). Other large-scale projects in research and development will help us understand, detect, and prevent these phenomena of emerging cases.

Unravelling the genetic keys to improve canola crop yield – University News: The University of Western Australia

Posted: at 7:29 pm

An international team of researchers, including one from The University of Western Australia, has successfully unravelled the genomes of 418 unique samples of rapeseed from across the globe to identify traits that breeders can use to improve crop yield.

The study Genomic selection and genetic architecture of agronomic traits during modern rapeseedBreeding published in Nature Genetics, follows a four-year collaboration between the scientists from Australia, China and the United States.

Professor Jacqueline Batley, from UWAs School of Biological Sciences and The UWA Institute of Agriculture, who is an author on the paper, said that rapeseed, known as canola in Australia, is the second most important oil-producing crop worldwide.

Which means that breeders are looking at ways that they can generate plants with the desired characteristics or traits that will allow them to minimise crop losses and maximise crop yields, Professor Batley said.

While the adaption, yield and quality of canola have all considerably improved in recent decades due to intensive breeding the genetics underlying desirable traits such as the architecture of the plant, seed weight and oil content have remained unclear because these are controlled by multiple genes.

Working together, the research team unravelled the genomes of 418 diverse rapeseed accessions from different geographical locations representing global genetic diversity. In doing so, they were able to identify the genes behind 56 traits that were modified during rapeseed improvement.

This provided us with insights into the genetic control of these important traits, Professor Batley said.

Taken together, our study revealed a landscape of genomic variation for diverse varieties and artificial selection or adaptation during rapeseed breeding. The results are a real insight into the make-up of rapeseed and should help accelerate future breeding for crop improvement.

Professor Batley said the complex genetic sequencing generated in the ground-breaking study will not only be an indispensable resource for genome-assisted rapeseed breeding but also a valuable database for other scientists conducting research on rapeseed.

Truth Social Buyer Warns of Bankruptcy Risk Given Trump’s Past Failures – Newsweek

Posted: at 7:28 pm

The company purchasing Donald Trump's media network, Truth Social, warned investors on Monday that there might be a bankruptcy risk given the former president's history of failed business ventures.

A regulatory filing by Digital World Acquisition Corp. highlighted several examples of bankruptcy associated with Trump while noting that there is "no guarantee" Truth Social will be successful.

Digital World announced a merger with Trump Media and Technology Group (TMTG), which owns Truth Social, in October. The social media network was launched in February after the former president was barred from mainstream social media platforms in the aftermath of the January 6, 2021, riot at the U.S. Capitol.

In Monday's filing, Digital World outlined the bankruptcies of several Trump ventures, including Trump Taj Mahal, Trump Plaza and Trump Castle in Atlantic City, as well as the failures of Trump University, Trump Vodka, Trump Steaks and GoTrump.com.

"A number of companies that had license agreements with President Trump have failed. There can be no assurances that TMTG will not also fail," the filing states. "While all of the foregoing were in different businesses than TMTG, there can be no guarantee that TMTG's performance will exceed the performance of those entities."

Trump will maintain significant influence over TMTG, controlling roughly 47 to and 58 percent of the company and serving as its chairman, according to the filing. The agreement also states that Trump has pledged to post on Truth Social six hours before making similar posts on other platforms, in order to maximize exposure on the site. After that, Trump may post on any other social media platform he has access to.

In the first few months after its launch, Truth Social was largely deemed a disaster by users who reported that the site was overrun by bots and technical errors, while hundreds of thousands of people were put on waitlists to join. Trump and his family didn't even appear to be enthusiastic about the app in its early days. The former president remained largely silent on the platform until April, while some of his children have maintained a heavier presence on Twitter.

Truth Social has been criticized for having an interface that closely resembles Twitter, from which Trump has been suspended. However, Tesla CEO Elon Musk, who has had an offer accepted to buy Twitter for $44 billion, said he would reinstate Trump's account if the deal is complete.

In response to its rocky start, Truth Social announced last month that it would attempt to undergo "major capacity upgrades" to improve the "performance and reliability" of the app.

Newsweek reached out to TMTG for comment.

Canadian businesses bankruptcies surge and some fear this is just the beginning – Toronto Star

Posted: at 7:28 pm

Business bankruptcies in Canada moved closer to pre-pandemic levels in the first quarter of 2022, jumping almost 34 per cent year-over-year in what some experts warn could be the start of a growing wave of failures.

There were 807 business bankruptcies and proposals in Q1, up from 733 in the previous quarter and 603 in the first quarter of 2021. Business bankruptcies have stayed significantly lower than normal during the pandemic thanks to government subsidies and loans, but the business community and experts have been saying the lull couldnt and shouldnt last.

In comparison, bankruptcies and insolvencies in the first quarter of 2019 totalled 972, meaning this quarters numbers are still almost 17 per cent down from the last full pre-pandemic Q1.

The question is whether insolvencies will rise back to pre-pandemic levels and stay there or whether they will go higher.

According to the Canadian Association of Insolvency and Restructuring Professionals (CAIRP), inflation and rising interest rates could push insolvency fillings up further as the year progresses.

Dan Kelly, president of the Canadian Federation of Independent Business, said he knew that business insolvencies would climb back up from their pandemic lows, but he expects the numbers to keep climbing above pre-pandemic levels as the year progresses.

Now that the subsidies are drying up, many business owners are trying to figure out whether its worth it to stay open, said Kelly. Less than half of CFIB members are back to pre-sales, he noted, and many are tens of thousands of dollars in debt.

Were in for several rough quarters, said Kelly, adding that the government could help ease the hangover by forgiving some or all of the loans it gave out during COVID-19. It could be a couple years of reckoning.

But David Macdonald, senior economist with the Canadian Centre for Policy Alternatives, has a more optimistic outlook.

Despite its current challenges, the Canadian economy is steady right now, he said, and that stability could help businesses get back on their feet, especially since summer is around the corner, a strong time of year for many sectors.

The latest uptick in bankruptcies could just be the return to pre-pandemic normal, he said, and not a sign of a coming tsunami.

Jean-Daniel Breton, chair of CAIRP, said theres no telling what will happen next. It all depends on a variety of measurable factors, like supply chain problems, inflation, and interest rates; as well as on immeasurable factors like consumer and business confidence.

Kellys concern is justified, said Breton, but he doesnt think bankruptcies will spiral out of control. Any backlog from the pandemic lull is likely to shake out over time, not all at once, he said.

The sectors with the biggest yearly increase in insolvency filings were construction and transportation and warehousing, the latter likely linked to rising gas prices, said Macdonald.

Inflation will certainly be a challenge for many businesses, said Macdonald, but it could actually be a boon for some industries.

However, a wave of bankruptcies significantly above pre-pandemic levels is not impossible, said Macdonald. If there is a recession, for example, then filings will likely go up.

Of course, bankruptcies dont tell the whole picture. Kelly noted that many small businesses dont bother to file for bankruptcy, instead choosing to simply close.

If anything, a bankruptcy filing is the funeral, not the death, he said, and the full scope of the pandemics economic effect is harder to quantify.

Breton said struggling business owners can benefit from early intervention, even saving their business from complete closure.

Insolvencies are part of the life cycle of a healthy economy, said Macdonald, and can help business owners exit a failing company less painfully.

It should be positive to get out from underneath this debt burden, he said.
