Salk Institute's ShortStop revolutionizes genetic search

Proteins sustain life as we know it, serving many important structural and functional roles throughout the body. But these large molecules have cast a long shadow over a smaller subclass of proteins called microproteins.

New method uses exosome stiffness for lung cancer gene detection

The research team led by Senior Researchers Yoonhee Lee from the Division of Biomedical Technology and Gyogwon Koo from the Division of Intelligent Robot at DGIST (under President Kunwoo Lee) has developed a technology that distinguishes lung cancer gene mutations solely by measuring the "stiffness" of exosomes-tiny particles released from cancer cells in the bloodstream-using atomic force microscopy (AFM).

Vanderbilt team explores functional β-cell enhancement for diabetes

If it has seemed like more people you know are developing diabetes, you are right. The diabetes epidemic is not called that for nothing: According to the American Diabetes Association, over 10 percent of the U.S. population-approximately 38.4 million people-had diabetes in 2021, and 1.2 million more people get diagnosed each year.

Marbling of fat inside muscles found to block healing and weaken strength

Consider the delicate web of fat in a Wagyu steak. The "marbling" that makes carnivore connoisseurs swoon is a visual heuristic for quality flavor.

Researchers map atomic structure of protein complex driving cilia movement

A team led by UT Southwestern Medical Center researchers has uncovered the atomic structure of a protein complex pivotal to the function of motile cilia, the hair-like structures extending from the surfaces of many cell types that generate their movement.

Decoding DNA packing: Understanding nucleosomes' role in cellular efficiency

Each cell in our bodies carries about two meters of DNA in its nucleus, packed into a tiny volume of just a few hundred cubic micrometers-about a millionth of a milliliter. The cell manages this by winding the strings of DNA around protein spools. The protein-DNA complexes are called nucleosomes, and they ensure that DNA is safely stored.

Researchers discover new trigger for mitophagy

Autophagy is essentially the 'rubbish collection' of our cells. If there are problems in this process, which is so important for our health, diseases such as Parkinson's can result. In their latest study, leading cell biologists at the Max Perutz Labs at the University of Vienna investigated mitophagy - a form of autophagy - and came to a remarkable conclusion: the researchers have described a new trigger for mitophagy.

VCU Massey pioneers clinical trial of novel GGT-1 inhibitor PTX-100

VCU Massey Comprehensive Cancer Center is the first site in the United States to be activated in a global Phase 2a clinical trial evaluating PTX-100 (AKA GGTI-2418), a first-in-class small molecule inhibitor of geranylgeranyl transferase-1 (GGT-1), for the treatment of cutaneous T-cell lymphoma (CTCL), a rare and often treatment-resistant T-cell lymphoma.

Blocking nutrient scavenging weakens pancreatic tumor defenses

Cancer cells and tumors do not exist in a vacuum. Far from the isolation and self-sufficiency of the fictional Wakanda, tumors develop in and alter the nearby milieu of immune cells, connective tissue, blood vessels and a sea of proteins and carbohydrates that provide structure and other supportive functions.
