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.

IRF-5 identified as key to preventing immune cell exhaustion

In fighting chronic infections or certain cancers, CD8+ T cells-the immune system's frontline soldiers-eventually become exhausted. They lose effectiveness and respond less efficiently to threats.

Study identifies SDR42E1's role in vitamin D pathway

Vitamin D is not only an essential nutrient, but also the precursor of the hormone calcitriol, indispensable for health: it regulates the uptake of phosphate and calcium necessary for bones by the intestines, as well as cell growth and the proper function of muscles, nerve cells, and the immune system.

New insights into brain fueling could lead to treatments for stroke, neurodegeneration

A new Yale study has revealed that neurons - the energy-hungry cells that connect and direct activity in the brain - are equipped with "backup batteries" that kick in to keep the brain running during periods of metabolic stress.
