Hwang and colleagues lay out their platform, which could one day be integrated not only into dental implants but other technologies, such as joint replacements, as well.

More than 3 million people in America have dental implants, used to replace a tooth lost to decay, gum disease, or injury. Implants represent a leap of progress over dentures or bridges, fitting much more securely and designed to last 20 years or more.

But often implants fall short of that expectation, instead needing replacement in five to 10 years due to local inflammation or gum disease, necessitating a repeat of a costly and invasive procedure for patients.

What’s exciting about our findings is that we have identified a molecular pathway that is activated in normal acute wounds in humans, and altered in diabetic wounds in mice,” said Ghaidaa Kashgari, Ph.D., a postdoctoral researcher in the UCI School of Medicine Department of Medicine. “This finding strongly indicates clinical relevance and may improve our understanding of wound healing biology and could lead to new therapies.

A University of California, Irvine-led study identifies a new molecular pathway that promotes the healing of wounds in the skin. Titled “GRHL3 activates FSCN1 to relax cell-cell adhesions between migrating keratinocytes during wound reepithelialization,” the study was published today in JCI Insight.

The molecular pathway identified is controlled by an evolutionary conserved gene called a Grainyhead like 3 (GRHL3), which is a gene required for mammalian development. Without this gene, several abnormalities may occur, including spina bifida, defective epidermal barrier, defective eyelid closure and soft-tissue syndactyly, a condition in which children are born with fused or webbed fingers.

Many human diseases can differ between males and females in their prevalence, manifestation, severity or age of onset. Examples include Lupus, where more than 80% of patients are females; Alzheimer’s disease, where females have higher incidence and tend to suffer quicker cognitive decline; and COVID-19 infections that are frequently more severe in males.

These sex differences may have a genetic basis that is attributable to the sex chromosomes. The X chromosome—one of the two sex chromosomes—is known to play an important role in human development and disease. New research led by Penn State College of Medicine reveals for the first time that sex-biased diseases can be attributable to genes that escape X chromosome inactivation (XCI), a process that ensures that females do not overexpress genes on their X-chromosomes.

The team developed a genetic tool that can identify these XCI escape genes, and it may also help in determining whether a female will develop a sex-biased disease and if the disease will become progressively worse over time. The tool may even be useful in understanding the sex differences in immune responses to COVID-19, as the disease is thought to produce more severe symptoms and higher mortality in men than in women.

Summary: A new study on aging reveals a surprising discovery about the connection between protein shape and mitochondrial health.

Every cell in the body goes through thousands of chemical reactions each day, and each reaction involves tiny protein molecules folded into precise shapes to perform their functions. Misfolded proteins underlie some of the most common and devastating diseases of aging, like Alzheimer’s and Parkinson’s. A major focus of aging research is discovering ways to maintain protein shape and prevent misfolded proteins from wreaking havoc on cellular function.

New photo-oxygenation catalyst targets amyloid structure, recruits brain immune system cells.

A small, light-activated molecule recently tested in mice represents a new approach to eliminating clumps of amyloid protein found in the brains of Alzheimer’s disease patients. If perfected in humans, the technique could be used as an alternative approach to immunotherapy and used to treat other diseases caused by similar amyloids.

Researchers injected the molecule directly into the brains of live mice with Alzheimer’s disease and then used a specialized probe to shine light into their brains for 30 minutes each day for one week. Chemical analysis of the mouse brain tissue showed that the treatment significantly reduced amyloid protein. Results from additional experiments using human brain samples donated by Alzheimer’s disease patients supported the possibility of future use in humans.

Isaac Newton’s groundbreaking scientific productivity while isolated from the spread of bubonic plague is legendary. University of California San Diego physicists can now claim a stake in the annals of pandemic-driven science.

A team of UC San Diego researchers and colleagues at Purdue University have now simulated the foundation of new types of artificial intelligence computing devices that mimic brain functions, an achievement that resulted from the COVID-19 pandemic lockdown. By combining new supercomputing materials with specialized oxides, the researchers successfully demonstrated the backbone of networks of circuits and devices that mirror the connectivity of neurons and synapses in biologically based neural networks.

The simulations are described in the Proceedings of the National Academy of Sciences (PNAS).

Wageningen is one of a clutch of research institutions globally that hold patents on CRISPR, a technique that enables precise changes to be made to genomes, at specific locations. Other institutions — including the Broad Institute in Cambridge, Massachusetts, and the University of California, Berkeley, which have some of the largest portfolios of patents on the subject — also provide CRISPR tools and some intellectual property (IP) for free for non-profit use. But universities could do better to facilitate access to CRISPR technologies for research.

Universities hold the majority of CRISPR patents. They are in a strong position to ensure that the technology is widely shared for education and research.
