Scientists ID molecular 'switch' in liver that triggers harmful effects of saturated and trans fats
...at was isolated in 2002. Experiments including the measurement of gene activity by microarrays showed that saturated and trans fats caused greater activity of the gene that makes PGC-1beta co-activator than did unsaturated fats. The research also showed that when the fats triggered PGC-1beta, the co-activator i...Recent breakthroughs in common adult leukemia highlighted in New England Journal of Medicine
