Making new strides in their ongoing effort to understand mechanisms behind the relentless growth of cancer cells, researchers at Dartmouth Medical School have found a promising key that may open doors to future treatments in pancreatic and other forms of cancer. The innovation lies in manipulating an overabundance of chemo-resistant molecules in pancreatic cancer that inactivate pathways that would normally suppress cell growth.
Published in the June 10 issue of the Journal of Biological Chemistry, the study was led by Dr. Murray Korc, a pioneer in early research on growth factor receptors in pancreatic cancer, and chair of the department of medicine at Dartmouth Medical School (DMS) and Dartmouth-Hitchcock Medical Center, and a member of the Norris Cotton Cancer Center. His teams research has focused on suppressing pancreatic tumor growth by determining the mechanisms that enable the cells to grow so quickly.
"Pancreatic cancer is an incredibly resilient and aggressive disease," said Korc. "It grows quickly without causing symptoms, is resistant to chemotherapy, has a strong tendency to metastasize, and patients are often beyond surgery when it is diagnosed."

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
