Johns Hopkins Medicine scientists report they have probed the atomic structure of proteins to add to evidence that the wobbles, shakes and quivers of proteins play a critical role in their ability to function. The findings of the research may help scientists design new drugs that can modify or disrupt the intricate “dances” of proteins to alter their functions.
Gábor Balázsi, PhD, and his research team in the Laufer Center and the Department of Biomedical Engineering at Stony Brook University are embarking upon a new way to research cells, the building blocks of life and often triggers to disease when their behavior changes.
Johns Hopkins Medicine researchers say they discovered that a special sugar molecule could play a key role in the development of Alzheimer’s disease. If further research confirms the finding, the molecule, known as a glycan, could serve as a new target for early diagnostic tests, treatments and perhaps prevention of Alzheimer’s disease, say the researchers.

Researchers studying how small worms defend themselves against pathogens have discovered a gene that acts as a first-line response against infection. They identified “ZIP-1” as a centralized hub for immune response, a finding could have implications for understanding human immunity against viruses.
Ever since the first barcode appeared on a pack of chewing gum in 1974, the now-ubiquitous system has enabled manufacturers, retailers and consumers to quickly and effectively identify, characterize, locate and track products and materials. In a paper first posted online Nov. 26, 2021, in the journal Cell, researchers at Johns Hopkins Medicine and The Johns Hopkins University demonstrate how they can do the same thing at the molecular level, studying the ways cancer cells “talk” with one another.
Among their many extraordinary feats, some planarian flatworms reproduce by tearing off pieces of themselves to regenerate new worms. Now, researchers at the Stowers Institute for Medical Research have discovered that this process is controlled by Hox genes, a family of genes known to orchestrate important aspects of early development.
Hopkins Medicine researchers say they have found that a protein that helps form a structural network under the surface of the cell’s “command center” — its nucleus — is key to ensuring that DNA inside it remains orderly.

In a new Cell Reports study, researchers at La Jolla Institute for Immunology demonstrate how Ebola virus has found a different way to get things done. The virus encodes only eight proteins but requires dozens of functions in its lifecycle. The new study shows how one of Ebola virus’s key proteins, VP40, uses molecular triggers in the human cell to transform itself into different tools for different jobs.
In a series of experiments that began with amoebas — single-celled organisms that extend podlike appendages to move around — Johns Hopkins Medicine scientists say they have identified a genetic pathway that could be activated to help sweep out mucus from the lungs of people with chronic obstructive pulmonary disease a widespread lung ailment.
Viruses churn out genetic material in parts of the cell where it's not supposed to be. Cancer cells do too. A new study shows that a tumor-suppressor enzyme called DAPK3 is an essential component of a multi-protein system that senses misplaced genetic material in tumor cells, and slows tumor growth by activating the fierce-sounding STING pathway.
A new study from the University of California, Irvine shows that compounds in both green and black tea relax blood vessels by activating ion channel proteins in the blood vessel wall. The discovery helps explain the antihypertensive properties of tea and could lead to the design of new blood pressure-lowering medications.
According to the World Health Organization, one in six worldwide deaths are attributed to cancer, but not due to initial malignant tumors. They were caused by the spread of cancer cells to surrounding tissues, which consist largely of collagen. That was the focus of a recent study by Stanford University and Purdue University researchers.
Researchers identified spinal cord neurons responsible for an itchy sensation after an epidural morphine injection and found a drug that may fix the problem without reducing morphine’s pain-killing effects.

The release of massive amounts of proteins called cytokines can lead to some of the most severe symptoms of COVID-19.
It can be hard to dispute the common adage ‘survival of the fittest’. After all, “most of the genes in the genome are there because they’re doing something good,” says Sarah Zanders, PhD, assistant investigator at the Stowers Institute for Medical Research. But, she says, “others are just there because they’ve figured out a way to be there.”

A compound commonly found in pickled capers has been shown to activate proteins required for normal human brain and heart activity, and may even lead to future therapies for the treatment of epilepsy and abnormal heart rhythms.
In one of the first studies addressing the role of sex hormones’ impact on stem cells in the gut, scientists outline new insights showing how a steroidal sex hormone that is structurally and functionally similar to human steroid hormones drastically alters the way intestinal stem cells behave, ultimately affecting the overarching structure and function of this critical organ. The authors found that ecdysone, a steroid hormone produced by fruit flies, stimulates intestinal stem cell growth and causes the gut of the female fruit fly to grow in size, as well as other critical changes.
