Two Genes That Drive Aggressive Brain Cancers Discovered

Thursday, December 31st, 2009

A team of Columbia scientists have discovered two genes that, when simultaneously activated, are responsible for the most aggressive forms of human brain cancer. This finding was made possible by the assembly of the first comprehensive network of molecular interactions that determine the behavior of these cancer cells, a map so complex and elusive that, until now, it could not be constructed…

Cystic Fibrosis Protein’s Secret Life Revealed, US Study

Thursday, December 31st, 2009

Researchers have made an important discovery about the secret life of the defective protein that causes cystic fibrosis: while scientists already knew that CFTR protein regulates the acid-alkali balance in cells, what they didn’t know, until this study revealed it, was what turns that ability on and off…

Gene Therapy Makes Mice Breath Easier

Thursday, December 31st, 2009

Individuals with single-gene mutations that mean they have abnormally low levels of the protein alpha-1 antitrypsin are highly susceptible to emphysema, a progressive lung disease that causes severe shortness of breath. Previous attempts to correct single-gene defects that cause lung disease by gene transfer have failed to achieve sustained gene expression in the mouse lung…
