Dental researchers identify protein key to wound healing

In many ways, the process to heal a wound parallels the steps involved in repairing, for example, a pothole. Both require specific supplies: cells and platelets, or asphalt and sand. And both processes necessitate a way transport those supplies, like a safe and accessible roadway. For the body, that means a network of […]

Biologists discover how pancreatic tumors lead to weight loss

Patients with pancreatic cancer usually experience significant weight loss, which can begin very early in the disease. A new study from MIT and Dana-Farber Cancer Institute offers insight into how this happens, and suggests that the weight loss may not necessarily affect patients’ survival. In a study of mice, the […]

State of the art imaging challenges our understanding of how platelets are made

Correlative light-electron microscopy is being used to increase our knowledge of how platelets are made in the body and the results are challenging previously held understandings. Platelets are uniquely mammalian cells, and are the small cells of the blood that are critical for us to stop bleeding when we cut […]

How a Thieving Transcription Factor Dominates the Genome

The Big Question At some point in a stem cell's life, it must make an irreversible transition to develop into a particular cell type. When this happens, its nucleus begins to bustle with activity: Proteins called transcription factors latch onto the cell's DNA at specific locations (called binding sites) to […]

Electrical Wire Properties of DNA Linked to Cancer

Known as DNA charge transport, this biochemical process was first discovered in the early 1990s by Caltech's Jacqueline Barton, the John G. Kirkwood and Arthur A. Noyes Professor of Chemistry, through chemistry experiments using synthetic DNA. Her research group then found evidence that this charge transport chemistry might be utilized by […]
