Dr. Antonio Giordano, MD, Ph.D. — President and Founder, Sbarro Health Research Organization

Integrated And Cross-Disciplinary Research Focused on Diagnosing, Treating And Curing Cancers — Dr. Antonio Giordano MD, PhD, President & Founder, Sbarro Health Research Organization.

Dr. Antonio Giordano, MD, Ph.D., (https://www.drantoniogiordano.com/) is President and Founder of the Sbarro Health Research Organization (https://www.shro.org/), which conducts research to diagnose, treat and cure cancer, but also has diversified into research beyond oncology, into the areas of cardiovascular disease, diabetes and other chronic illnesses.

Dr. Giordano is also a Professor of Molecular Biology at Temple University in Philadelphia, a ‘Chiara fama’ Professor in the Department of Pathology & Oncology at the University of Siena, Italy, and Director of the Sbarro Institute for Cancer Research and Molecular Medicine, and the Center for Biotechnology, at Temple’s College of Science & Technology.

In his research throughout the years, Dr. Giordano has identified numerous tumor suppressor genes, including Rb2/p130, which has been found to be active in lung, endometrial, brain, breast, liver and ovarian cancers, as well as interesting synergistic effects of gamma radiation in combination with this gene, accelerating the death of tumor cells.

Dr. Giordano went on to discover Cyclin A, Cdk9 (which is known to play critical roles in HIV transcriptions, inception of tumors, and cell differentiation), and Cdk10. Dr. Giordano also developed patented technologies for diagnosing cancer.

A Common Infection Could Be a Trigger For Multiple Sclerosis, Large Study Finds

For most of the time since the first description of multiple sclerosis (MS) in 1,868 the causes of this disabling disease have remained uncertain. Genes have been identified as important, which is why having other family members with MS is associated with a greater risk of developing the disease.

A recent study my colleagues and I conducted found that several types of infection during the teenage years are associated with MS after age 20. Our study didn’t investigate whether people who are more likely to have genetic risks for MS were also more likely to have worse infections.

This might explain why people with MS also have more infections that need hospital treatment.

Genetics and Skeletal Biology Debunks Popular Theory of Native American Origins

Latest scientific findings suggest the ancestral Native American population does not originate in Japan, as believed by many archaeologists.

A widely accepted theory of Native American origins coming from Japan has been attacked in a new scientific study, which shows that the genetics and skeletal biology “simply does not match-up.”

The findings, published on October 12 2021, in the peer-reviewed journal PaleoAmerica, are likely to have a major impact on how we understand Indigenous Americans’ arrival to the Western Hemisphere.

Harvard University professor geneticist Dr. George Church stops by the Institute

Talking about RejuvenateBio starts at 20:30. Mentions there are 300 known genes concerning human aging and 45 of those have been tested in mice with what sounds like success.

Wow! Where do I start. I woke up and seen Dr. George Church on Bloomberg news. They was discussing a new biotech startup company called Rejuvenate Bio. A life extension company that seeks to reverse aging in dogs. Then apply that knowledge to humans. I ask Dr. Church about what he thinks is the cause of aging. t. Dr. Church thinks its a genetic reason why we age. Dr. Church is a cofounder of a company called Colossal is a company that wants to create a hybrid between the east asian elephant and the woolly mammoth. The purpose of doing this is to fight climate change and prevent the extinction of the east asian elephant.

Brain’s White Matter Integrity Disrupted in People With Alzheimer’s Gene Mutation

The structural integrity of the brain’s white matter as measured with an advanced MRI technique is lower in cognitively normal people who carry a genetic mutation associated with Alzheimer’s disease than it is in non-carriers, according to a study in Radiology. Researchers said the findings show the promise of widely available imaging techniques in helping to understand early structural changes in the brain before symptoms of dementia become apparent.

People who carry the autosomal dominant Alzheimer disease (ADAD) mutation have a higher risk of Alzheimer’s disease, a type of dementia that affects about one in nine people in the United States. The mutation is linked to a buildup of abnormal protein called amyloid-beta in the brain that affects both the gray matter and the signal-carrying white matter.

“It’s thought that the amyloid deposition in the gray matter could disrupt its function, and as a result the white matter won’t function correctly or could even atrophy,” said study lead author Jeffrey W. Prescott, M.D., Ph.D., neuroradiologist at the MetroHealth Medical Center in Cleveland.

Scientists Can Grow Meat Protein. With Gene-Edited Barley?

ORF Genetics in Iceland is growing 100,000 genetically engineered barley plants in a greenhouse measuring over 22 square feet (2 sq m) to create lab-grown meat.

This cutting-edge approach has the potential to lower prices, eliminate reliance on live animals in the lab-grown meat sector, and speed up the scaling-up process, according to BBC. And, with the fact that meat accounts for nearly 60 percent of all greenhouse gases from food production in mind, such a development could have far-reaching implications in the fight against climate change.

Migraines Caused by Alterations in Metabolite Levels

“Lower levels of DHA are associated with inflammation, cardiovascular and brain disorders, such as depression, which are all linked to migraine risk.”

Professor Nyholt said LPE(20:4) was a chemical compound that blocked the production of an anti-inflammatory molecule called anandamide.

Summary: Researchers have identified causal genetic links to three blood metabolite levels that increase migraine risks.

Migraines are a pain in the head and in the hip pocket, but newly discovered genetic causes by QUT researchers could lead the way to new preventative drugs and therapies.

Genetic analyses findings were published in The American Journal of Human Genetics by Professor Dale Nyholt and his PhD candidates Hamzeh Tanha and Anita Sathyanarayanan, all from the QUT Centre for Genomics and Personalised Health.

Scientists Genetically Modify Plants to Grow Meat Protein

Researchers in Iceland are growing over 100,000 genetically modified barley plants inside a greenhouse for a very unusual purpose: creating lab-grown meat, the BBC reports.

The altered barley gets harvested and purified to extract “growth factor” proteins, which, in turn, can be used to cultivate lab-grown meat — an innovation that could make the lab-grown meat industry rely even less on live animals in the future.

The company behind the greenhouse, ORF Genetics, is growing the biogenetically engineered barley over 22,000 square feet using high-tech hydroponic cultivation methods.

Scientists Revive 28,000-Year-Old Woolly Mammoth Cells in Mice

Circa 2019 o.o

The dream of resurrecting species like the woolly mammoth via genetic engineering is old enough that I remember reading articles about it in school 30 years ago. We may never be able to recover enough pristine genetic material from an intact woolly mammoth to make that approach feasible, but scientists working on the remains of the frozen mammoth known as Yuka have taken an incredible step nonetheless, demonstrating that at least some cell functions can remain intact after nearly 30,000 years.

Yuka, found in 2,010 is a juvenile woolly mammoth, considered to be the most intact and well-preserved mammoth ever found. That was critical to the researchers’ efforts — earlier tests in 2009 with a less-well-preserved but younger specimen at 15,000 years old yielded no positive results at all.

To be clear: The scientists in question were not able to bring Yuka’s cells back to life. After removing 88 nucleus-like structures from Yuka’s cells, they injected these structures into mouse oocytes — eggs — to see if they could be coaxed back into biological activity. While the cells ultimately failed to divide, they did undertake some of the steps required for cell division, such as spindle assembly. This spindle assembly process ensures that chromosomes are properly prepared to divide before the parent cell actually splits.
