New probes offer insight into cholesterol's role in Alzheimer's disease

The search for answers to Alzheimer's disease and other neurodegenerative disorders remains one of the most pressing goals in brain research. Maciej J. Stawikowski, Ph.D., an assistant professor of chemistry and biochemistry at Florida Atlantic University's Charles E. Schmidt College of Science, believes the key may lie in understanding how cholesterol and other lipids move through cells and affect their communication.

Unveiling the metabolic pathways of Fusobacterium nucleatum in OSCC

A recent study has made significant strides in uncovering how the oral microbiome, particularly the bacterium Fusobacterium nucleatum, plays a crucial role in the progression of oral squamous cell carcinoma (OSCC). By identifying key interactions between this common oral bacterium and host cells, the research has unveiled important metabolic pathways and mechanisms that may serve as potential therapeutic targets.

Bidirectional movement drives DNA loop formation

Scientists from Delft, Vienna, and Lausanne discovered that the protein machines that shape our DNA can switch direction. Until now, researchers believed that these so-called SMC motors that make loops into DNA could move in one direction only. The discovery, which is published in Cell, is key to understanding how these motors shape our genome and regulate our genes.
