PHILADELPHIA – The gene for the protein p53 is the most frequently mutated in human cancer. It encodes a tumor suppressor, and traditionally researchers have assumed that it acts primarily as a regulator of how genes are made into proteins. No…
HOUSTON – Like a bounty hunter returning escapees to custody, a cancer-fighting gene converts organ cells that change into highly mobile stem cells back to their original, stationary state, researchers report online at Nature Cell Biology.

LA JOLLA, CA — Scripps Research Institute scientists have converted adult skin cells directly into beating heart cells efficiently without having to first go through the laborious process of generating embryonic-like stem cells. The powerful gener…
Stanford, CA — Plant biologists have discovered the last major element of the series of chemical signals that one class of plant hormones, called brassinosteroids, send from a protein on the surface of a plant cell to the cell’s nucleus. Although …
HOUSTON – By sticking a chemical group to it at a specific site, a protein arrests an enzyme that may worsen and spread cancer, an international research team led by scientists at The University of Texas MD Anderson Cancer Center reports in …
CINCINNATI — Using fruit flies as a model to study embryo formation, scientists report in Nature Cell Biology that molecular breakdown of a protein called Bicoid is vital to normal head-to-tail patterning of the insect’s offspring.
Published onl…
Cold Spring Harbor, N.Y. — The nucleus of a cell, which houses the cell’s DNA, is also home to many structures that are not bound by a membrane but nevertheless exist as distinct compartments. A team of Cold Spring Harbor Laboratory (CSHL) scienti…
New research that provides potential for exciting new approaches to targeting diseases such as cancer has been announced by an international team of academics.
They have also announced the potential for more targeted treatments following their ide…
Palo Alto, CA — Researchers at the Carnegie Institution for Science, with colleagues at the Nara Institute of Science and Technology, observed for the first time a fundamental process of cellular organization in living plant cells: the birth of mic…
Biologists at the University of California, San Diego have discovered that a gene critical for programmed cell death is also important in the loss of adult stem cells, a finding that could help to improve the health and well-being of patients underg…
In a study of egg cells using time-lapse microscopy, researchers at the University of California, San Diego School of Medicine and the Ludwig Institute for Cancer Research have discovered an unusual property of meiosis — cell division that prod…
