Cancer Cells Adapt Energy Needs to Spread Illness to Other Organs

LeBleu_V-cropped_1.jpg

Scientists at The University of Texas MD Anderson Cancer Center have found that cancer cells traveling to other sites have different energy needs from their “stay-at-home” siblings which continue to proliferate at the original tumor site.

New Cancer Drug Target Involving Lipid Chemical Messengers

More than half of human cancers have abnormally upregulated chemical signals related to lipid metabolism, yet how these signals are controlled during tumor formation is not fully understood. Researchers report that TIPE3, a newly described oncogenic protein, promotes cancer by targeting these pathways.

X-Rays Unlock a Protein’s SWEET Side

Feng_EDfig7_A.jpg

Understanding just how sugar makes its way into the cell could lead to the design of better drugs for diabetes patients and an increase in the amount of fruits and vegetables farmers are able to grow. Stanford University researchers have recently uncovered one of these "pathways" into the cell by piecing together proteins slightly wider than the diameter of a strand of spider silk.

A Better Way to Track Emerging Cell Therapies Using MRIs

In a paper published September 17 in the online journal Magnetic Resonance in Medicine, researchers at the University of California, San Diego School of Medicine, University of Pittsburgh and elsewhere describe the first human tests of using a perfluorocarbon (PFC) tracer in combination with non-invasive magnetic resonance imaging to track therapeutic immune cells injected into patients with colorectal cancer.

Dwindling Wind May Tip Predator-Prey Balance

Rising temperatures and shifting precipitation patterns may get the lion’s share of our climate change attention, but predators may want to give some thought to wind, according to a University of Wisconsin Madison zoologist’s study, which is among the first to demonstrate the way “global stilling” may alter predator-prey relationships.

Mayo Researchers Reveal Pathway that Contributes to Alzheimer’s Disease

Researchers at Jacksonville’s campus of Mayo Clinic have discovered a defect in a key cell-signaling pathway they say contributes to both overproduction of toxic protein in the brains of Alzheimer’s disease patients as well as loss of communication between neurons — both significant contributors to this type of dementia.
