Researchers link cell division and oxygen levels
Cells grow abundant when oxygen is available, and generally stop when it is scarce. Although this seems straightforward, no direct link ever has been established between the cellular machinery that senses oxygen and that ...

Hope in stopping melanoma from spreading: Study shows that inhibiting key protein prevents metastasis to lungs in mice
(Medical Xpress)—Researchers have identified a critical protein role in the metastasis of melanoma, the most serious form of skin cancer. Inhibition of the protein known as adenosine diphosphate ribosylation factor 6 (ARF6) ...

Scientists identify molecules in the ear that convert sound into brain signals
For scientists who study the genetics of hearing and deafness, finding the exact genetic machinery in the inner ear that responds to sound waves and converts them into electrical impulses, the language of the brain, has been ...

Preventing dangerous nonsense in human gene expression
Human genes are preferentially encoded by codons that are less likely to be mistranscribed (or "misread") into a STOP codon. This finding by Brian Cusack and colleagues from the Max Planck Institute for Molecular Genetics ...

How cells sense nutrients and fuel cancer cell growth
In cancer, genes turn on and off at the wrong times, proteins aren't folded properly, and cellular growth and proliferation get out of control. Even a cancer cell's metabolism goes haywire, as it loses the ability to appropriately ...
