Recent research has shown that a drug known as MI-2 can kill cells that cause a fatal brain cancer. But only now have scientists been able to explain how the compound works: by targeting cholesterol production in tumors.
Some cancers have been traced to changes in histones, proteins responsible for packaging DNA and regulating genes. Now, research from Rockefeller scientists shows that, among tumors, mutations to these proteins are a lot more common than previously suspected.
Scientists discovered a protein that plays a crucial role in regulating fatty acids, the molecules that make up body fat. This research could lead to new options for treating people with diseases associated with fatty acid buildup.
New research on leptin, a hormone that regulates appetite, reveals a previously unknown mechanism that may be responsible for at least 10 percent of obesity cases. The findings could help identify individuals with treatable forms of the condition.
When looking for food, the roundworm C. elegans searches the same area for up to 20 minutes before trying its luck at more distant locales. New research on the worm’s brain explains how this behavior arises at the level of molecules and cells.
Researchers have identified a rare type of cancer cell that cannot make cholesterol, a key nutrient. By targeting this deficiency, scientists may be able to develop new strategies for treating the disease.
Scientists have learned new tricks that could be useful in preventing mosquito-borne illnesses such as Zika and yellow fever. A new study shows that some appetite-reducing drugs can curtail the insects’ impulse to feed on warm-blooded hosts.
