Researchers identify genes in fruitflies that may shed light on human cancer spread

..., the first author of the study and a postdoctoral fellow in the Department of Biological Chemistry. "Cells must detach from where they are, migrate between other cells and tissues, and travel to a final destination." Although border cell migration in the fruitfly ovary may seem a far stretch for studying ...

Proteins spur diabetic mice models to grow blood vessels, nerves

...nt and may be important as a new therapy." Li and fellow researchers from the University of Utah and Stanford already had shown Netrin-1, a member of the netrins family, promotes blood vessel growth in laboratory cultures. But, until now, it had not been demonstrated that netrins work in animals. The res...

UC San Diego biologists solve plant growth hormone enigma

...t possible," explained Youfa Cheng, a postdoctoral fellow working with Zhao. "Even with the advances in technology, it took about three years to produce plants lacking at least four of the 11 YUCCA genes." Disrupting one YUCCA gene did not have any obvious effects. Therefore, there is overlap in the ...

Johns Hopkins lab scientists tame overactive CF protein

..." says co-author Neeraj Vij, Ph.D., a postdoctoral fellow at the Children's Center. "Inhibiting specific sites in VCP can lead to the development of CF drugs." "The goal is to develop small molecules that disrupt the binding between the VC protein and CFTR, much like tiny guided missiles that take out po...

...ame pathway," said Fantin, who was an HMS research fellow in genetics when the study was performed. She is currently a research scientist at Merck & Co. What may excite the growing band of researchers who are studying the Warburg effect, and cancer metabolism more generally, is the way the study resolv...

Pigeons provide clue to solving common problem in heart patients

...plasty," said Wagner, a professor of pathology and fellow of the American Heart Association. Genes "express," or produce, proteins that are used in building tissue. The process begins with "transcription," or the copying of a gene's DNA sequence. It is not known which genes might control the pigeons' he...

...ster, the fruit fly. Dr. Lehmann and post-doctoral fellow Lilach Gilboa, Ph.D., decoded the process in the developing fruit fly ovary that allows the ovary to monitor the number of germ cells it contains and to correct that number if the need arises. Germ cells are cells that give rise to either sperm or eg...

Everything in its place: Researchers identify brain cells used to categorize images

...hor David Freedman, PhD, HMS postdoctoral research fellow in neurobiology. "Some areas of the brain, particularly the frontal and temporal lobes, have been associated with visual categorization. Since these brain areas are all interconnected, an important next step will be to determine their relative roles...

For Stanford scientists, RNAi gene therapy takes two steps forward, one step back
