Electron Microscopy Reveals How Vitamin A Enters The Cell

Using a new, lightning-fast camera paired with an electron microscope, Columbia University Medical Center scientists have captured images of one of the smallest proteins in our cells to be “seen” with a microscope. The protein – called STRA6 – sits in the membrane of our cells and is responsible for transporting vitamin A into the […]

An Engineered Protein Can Disrupt Tumor-Promoting ‘Messages’ in Human Cells

Over a century of research has shined light on the once-murky innards of our cells, from the genes that serve as our “blueprints” to the proteins and other molecules that are our cellular taskmasters. Building on this basic knowledge, the search is underway for cellular mechanisms that could serve as gateways for new therapies. These […]
