Study shows for the first time how a specific cell gene affects transformation of others

An international team of seven institutions from Spain and the US including the University of Valencia has discovered for the first time that the biological activity of the c-MYC gene is necessary so that cell reprogramming occurs, that is, the process by which a specialised cell -for example, a neuron- is transformed into a different cell type.

Light-activated tools allow scientists to accurately probe intracellular phase separation

Creating new tools that harness light to probe the mysteries of cellular behavior, Princeton researchers have made discoveries about the formation of cellular components called membraneless organelles and the key role these organelles play in cells.

New strategy for developing cell replacement therapies to combat type 1 diabetes

Scientists have discovered the signals that determine the fate of immature cells in the pancreas. The research shows that they are very mobile and that their destiny is strongly influenced by their immediate environment.

Revolutionary new technology sheds light on why cancers form in specific cell types

While many cells in our bodies can accumulate oncogenic mutations, the majority of these events do not lead to tumor formation as these abnormal cells are eliminated by defense mechanisms.

Two types of cellular asymmetry govern shaping of cells into sheets and tubes

Scientists have developed a mathematical model showing that two types of cellular asymmetry, or 'polarity', govern the shaping of cells into sheets and tubes, according to an article in eLife.

Researchers map cells in the early human placenta to shed light on pregnancy complications

To treat and prevent pregnancy-related disorders, researchers must understand not only what can go wrong, but when. Complications, such as preeclampsia and pre-term birth, often occur in the second or third trimester, and most research to date has focused on those later stages of pregnancy. But the biological events that lead to these problems could start much earlier.

Early-life stress in mice hinders neuron development, causing attention problems

Women are roughly twice as likely as men to develop depression, anxiety and other stress-related problems, including difficulty with attention, and new research from Brown University neuroscientists sheds light on the biological reasons why.

Novel methodology for characterizing neurons could lead to better understanding of brain disease

It takes a lot of cells to make a human brain. The organ houses not only an enormous quantity of neurons (tens of billions), but also an impressive diversity of neuron types. In recent years, scientists have been developing inventories of these cell classes--information that will be essential for understanding how the brain works.

Microbiologists uncover how antibiotics help spread resistance

Bacteria can become insensitive to antibiotics by picking up resistance genes from the environment. Unfortunately for patients, the stress response induced by antibiotics activates competence, the ability of cells to take up and integrate foreign DNA, in microorganisms.
