Can plant research lead to new insights in cancer research?

...turning into a cancer cell. New insights from an unexpected quarter In a small plant like Arabidopsis (or the mouse ear cress), processes such as DNA doubling and cell division are also subject to a complex control system. The VIB research group, under the direction of Lieven De Veylder and Dirk Inz, is stu...

Surprising study reveals how cancer-causing protein activates

...adulthood, STAT3 presumably falls dormant, but its unexpected and continuous activation causes breast and prostate cells to develop and move through the body. Eugene Chin, M.D., a Rhode Island Hospital researcher and assistant professor (research) of surgery at Brown Medical School, said experts suspect that en...

UCLA/VA researchers discover fat gene

...elated to both excess and insufficient fat." In an unexpected finding, the study also discovered that lipin levels helped the fat cells metabolize glucose more efficiently, leading to lower blood-sugar levels. The obese mice with excess lipin in their fat tissue demonstrated even lower blood-sugar levels than ...

Spleen may be source of versatile stem cells

...ng islets of the pancreas. In a follow-up to that unexpected finding, members of the same team now report that these potential adult stem cells produce a protein previously believed to be present only during the embryonic development of mammals. The finding both supports the existence of these splenic stem c...

Timing is everything: First step in protein building revealed

"It's impossible to know for sure whether eIF1 is released completely in living creatures, but in our laboratory experiments that is clearly the case," adds Lorsch. "Even if it isn...

Foot-eye coordination: Visual signals trigger rapid step adjustments without falls

Balance is normally maintained during a step by a pre-step "ballistic throw" of the body that is tightly coupled to intended foot placement. Mid-step deviation of the foot would upset this coupling and coul...

The very unexpected life and death of a leukemic cell B cell chronic lymphocytic leukemia (CLL) is an incurable disease in which cells in the bone marrow grow and survive to the point where they become abnormal and malignant (leukemic). The progression of the diseas...

Prehistoric jawbone reveals evolution repeating itself

"Recent studies of jaw and ear function in primitive mammal-like reptiles indicate that the larger angular bone may have supported an eardrum while still part of the lower jaw," Hopson s...

Radio-tracking associated with 'dramatic shift' in water vole sex ratio

...the techniques they use had the potential to cause unexpected effects, and there have been many studies into the effects of radio-collars. However, this is the first study to show an association between radio-collars and sex ratio, although further work is needed to establish a causal link. According to Moorhou...

Liposome finding implies electrical effect on cell development

...s similar to natural cell membranes have revealed unexpected behavior in the presence of electrical fields that may provide a paradigm-shifting change in science's understanding of biomembrane function in operating living systems. Arizona State University chemists Mark Hayes and Michele Pysher have found that ...

Writing in the March 18 issue of Science, the researchers report that the yeast Candida glabrata use a family of proteins called sirtuins to block access to genes that would o...
