Scientists discover mechanism controlling spread of pancreatic cancer
INSTITUTE OF CANCER RESEARCH Key protein identified that helps turn pancreatic cancer cells into more aggressive form Pattern of cells in pancreatic tumours follows mathematical law first proposed by Alan Turing Fundamental discovery could pave way for new pancreatic cancer treatments Scientists have shown it is possible to reverse a key process that allows pancreatic...
Improved protein function opens way for new drug development concept
KAROLINSKA INSTITUTET Researchers at Karolinska Institutet and SciLifeLab in Sweden describe in a study published in Science how they have improved the ability of a protein to repair oxidative DNA damage and created a new protein function. Their innovative technique can lead to improved drugs for diseases involving oxidative stress, such as cancer, Alzheimer’s disease and lung...
Mapping out new routes to treat brain disorders
Cold Spring Harbor Laboratory (CSHL) Professor Hiro Furukawa takes an architectural approach to brain research. He creates structural 3D maps of important proteins that malfunction in brain disorders. Furukawa has zeroed in on a protein called the NMDA (for N-methyl-D-aspartate) receptor that plays a key role in learning and memory. The NMDA receptor acts as a channel to allow ions into neurons...
Investigators discover a ‘double life’ for a key Parkinson’s disease protein
by Brigham and Women’s Hospital A graphic depicts the “two faces of alpha-synuclein” and the transition from normal states (upper, organized molecular machines on a well-defined grid) to pathologic states in which there is membrane disruption, altered protein interactions and localization (lower, chaotic, disrupted machines, darker tone).

Protein linked to alcoholism relapse offers novel target for treatment
By Nick Lavars June 08, 2022 Research into alcohol use disorder has implicated a new protein in the anxiety associated with withdrawal Depositphotos Alcohol use disorder is a leading cause of preventable death and a complex disease, but by understanding its effects on brain function scientists hope to lower the risk and rates of relapse. The latest...
Roundworms offer new insights into Bardet-Biedl syndrome
UNIVERSITY OF MICHIGAN Scientists have identified a new role for a protein complex at the center of a human genetic disorder called Bardet-Biedl syndrome, or BBS, for which there is currently no cure. Bardet-Biedl syndrome arises when the BBSome protein complex malfunctions. Because the BBSome regulates the form and function of cilia, the hair-like structures...
Genetic roots of 3 mitochondrial diseases ID’d via new approach
WASHINGTON UNIVERSITY SCHOOL OF MEDICINE When something goes wrong in mitochondria, the tiny organelles that power cells, it can cause a bewildering variety of symptoms such as poor growth, fatigue and weakness, seizures, developmental and cognitive disabilities, and vision problems. The culprit could be a defect in any of the 1,300 or so proteins that...
Vaccine targeting a protein found to be effective against many types of cancers in several animals
by Bob Yirka, Medical Xpress Vimentin is overexpressed in tumor endothelial cells and is present extracellularly. a, b Vimentin mRNA (a; n = 3; qPCR) and protein (b; n = 4; flow cytometry) expression in isolated endothelial cells (EC) from human colon tumor (TEC) and normal colon (NEC). c Vimentin mRNA expression in isolated EC from human (colon, n = 13;...
