Placental Cells Secrete Factors That Protect Nerves from Ischemic Damage

Cells derived from placenta have been found to protect PC12 cells—rat-derived cells that behave similarly to and are used as stand-ins to study human nerve cells—in a culture-based ischemic stroke model.  More...

The technology promises to change the way pancreatic cancer research is done, offering a path to personalized treatment approaches (Photo courtesy of Cold Springs Harbor Laboratory).

Organoids Aid Discovery of New Approaches for Treating Pancreatic Cancer

Cancer researchers have established a method for culturing organoids from normal and cancerous mouse and human pancreatic tissues that is expected to boost development of personalized treatment approaches for this deadly disease.  More...

Inactivating Fatty Acid Synthase Reduces Inflammation by Interfering with Neutrophil Membrane Function

The enzyme fatty acid synthase was shown to regulate inflammation by sustaining neutrophil viability through modulation of membrane phospholipid composition.  More...

Image: A new finding goes against dogma, showing for the first time that the building blocks of a protein, called amino acids, can be assembled by another protein, and without genetic instructions. The Rqc2 protein (yellow) binds tRNAs (dark blue, teal), which add amino acids (bright spot in middle) to a partially made protein (green). The complex binds the ribosome (white) (Photo courtesy of Janet Iwasa, PhD, University of Utah).

Challenging Classic Science Principles, New Research Finds New Role for Proteins

A new study revealed for the first time that the essential components of a protein, called amino acids, can be assembled without blueprints—DNA and an intermediate template called messenger RNA. Researchers have observed an instance in which another protein specifies which amino acids are added.   More...

Cancer Cells with p53 Mutations Have Phosphatidylinositol Signaling Molecules with Shortened Lipid Acyl Chains

A recent study showed that cancer cells with mutations in the p53 gene were distinguished by reduced-length fatty acid moieties in their cell membranes.  More...
