‘Terminator’ protein suppresses tumorigenesis

Essential processes in mammalian cells are controlled by proteins called transcription factors. For example, the transcription factor HIF-1 is triggered by a low-oxygen situation to cause the cell to adapt to decreased oxygen.

Bacteria lurking in cancer cells may affect treatment

Cancer cells are comfy havens for bacteria. That conclusion arises from a rigorous study of over 1,000 tumor samples of different human cancers.

Explosion of immune cells in mouse lungs after birth may help protect against infections

An explosion in the number and types of immune cells in the lungs of newborn mice likely helps them adapt to breathing and protects them from infection, says a new study published today in eLife.

Researchers successfully transplant fully functional mini livers into rats

Using skin cells from human volunteers, researchers at the University of Pittsburgh School of Medicine have created fully functional mini livers, which they then transplanted into rats.

Study resolves contradictions surrounding p53 gene's role in pluripotent stem cell differentiation

The gene p53 is extremely important in cell biology and, hence, the world of cell replacement therapy. Its role is to regulate the cell cycle and halt the formation of tumors, leading to its nickname the "tumor suppressor gene."

Stem cell model sheds new light on the devastating process of neurodegeneration

A new study published today in Neuron led by The New York Stem Cell Foundation Research Institute's Valentina Fossati, Ph.D., creates astrocytes - an integral support cell in the brain - from stem cells and shows that in disease-like environments, these normally helpful cells can turn into neuron-killers.

Study uncovers how cancer cells protect themselves from viruses

Researchers at the Francis Crick Institute have uncovered how cancer cells protect themselves from viruses that are harmful to tumors but not to healthy cells. These findings could lead to improved viral treatments for the disease.

Columbia engineers develop novel technique to study how tissues flow in the embryo

As embryos develop, tissues flow and reorganize dramatically on timescales as brief as minutes. This reorganization includes epithelial tissues that cover outer surfaces and inner linings of organs and blood vessels.

Study sheds light on homologous recombination of DNA strands

As chromosomes go, X and Y make an unlikely pair. The X is large and contains thousands of genes critical for life. The Y, by contrast, is little more than a nub.

New insight into RNA movements can pave way for strategies to treat cancer

Research from Karolinska Institutet published today in Nature shows that an RNA molecule involved in preventing tumour formation can change its structure and thereby control protein production in the cell.
