Promising new direction for organ regeneration and tissue repair

Now a research team led by investigators at Beth Israel Deaconess Medical Center (BIDMC) and Dana-Farber/Boston Children’s Cancer and Blood Disorders Center has identified an entirely new approach to enhance normal tissue growth, a finding that could have widespread therapeutic applications. Their findings were published on-line this week in the Proceedings of the National Academy of Sciences (PNAS). Tissue regeneration is a process that is not fully understood, but previous research has demonstrated that endothelial cells lining the insides of small blood vessels play a key role in tissue growth. …

Oxygen – key to most life – decelerates many cancer tumors when combined with radiation therapy

In research examining tissue oxygenation levels and predicting radiation response, UT Southwestern scientists led by Dr. Ralph Mason reported in the June 27 online issue of Magnetic Resonance in Medicine that countering hypoxic and aggressive tumors with an "oxygen challenge" — inhaling oxygen while monitoring tumor response — coincides with a greater delay in tumor growth in an irradiated animal model…

Missing piece of pediatric cancer puzzle found

In a study published in the July issue of the Proceedings of the National Academy of Sciences, researchers found a missing piece of the pediatric cancer puzzle. Changxian Shen, PhD, senior research associate at the Center for Childhood Cancer and Blood Diseases at The Research Institute at Nationwide Children’s Hospital, and Peter Houghton, PhD, director of the center, may have identified one mechanism behind the early development of some pediatric solid tumors — as well as a target for future pediatric cancer therapies…

Molecular switch controls the destiny of self-eating cells

The study is the result of a collaboration of scientists at Karolinska Institutet in Sweden, University of Michigan, and University of California San Diego, USA, who were interested in finding out whether autophagy can be affected by events in the cell nucleus. Surprisingly, they discovered that a signal chain in the nucleus serves as a kind of molecular switch that determines whether the cell dies or survives. …

Strong pregnancy outcomes for survivors of childhood cancer

"Most women think that if they had cancer as a child, then they’ll never have children. It turns out that many of them can get pregnant. It just might be a little harder," said senior author Lisa Diller, MD, chief medical officer of Dana-Farber/Boston Children’s and medical director of the David B…

Targeting errant immune system enzyme kills myelodysplastic cells

Reporting their results July 8 in Cancer Cell, researchers say their successful laboratory tests in human MDS cells and mouse models of MDS provide a molecular target for designing new drugs to battle a syndrome with few effective treatments. "There is an urgent need to develop new targeted therapies that can eliminate MDS-initiating clone cells and provide a durable therapeutic response," said Daniel Starczynowski, PhD, lead researcher and a member of the Division of Experimental Hematology and Cancer Biology at Cincinnati Children’s Hospital Medical Center…

Moms often talk to children about the results of cancer genetic testing

"We know from women we’ve counseled at Georgetown that one of their main considerations of genetic testing for cancer risk is what the results will mean for their children," says the study’s lead author, Kenneth Tercyak, PhD, director of behavioral prevention research at Georgetown Lombardi. …
