New tool to grow cancer cells streamlines laboratory research
A new technique that allows the growth of both normal and cancer cells and keeps them alive indefinitely is transforming and expediting basic cancer research. 'We've had a glimpse of how these cells can provide an amazing advance in human cancer clinical research in preliminary work, and now we demonstrate how incredibly useful they are in laboratory cancer research,' says the lead researcher.

Tumor cells in the blood may indicate poor prognosis in early breast cancer
Tumor cells in bone marrow of early breast cancer patients predict a higher risk of relapse as well as poorer survival, but bone marrow biopsy is an invasive and painful procedure. Now, it may be possible to identify tumor cells in a routine blood sample and use them as prognostic markers, according to a study published May 15 in the Journal of the National Cancer Institute.

First test of pluripotent stem cell therapy in monkeys is a success
Researchers have shown for the first time in an animal that is more closely related to humans that it is possible to make new bone from stem-cell-like induced pluripotent stem cells (iPSCs) made from an individual animal's own skin cells. The study in monkeys also shows that there is some risk that those iPSCs could seed tumors, but that unfortunate outcome appears to be less likely than studies in immune-compromised mice would suggest.

Detailed studies reveal how key cancer-fighting protein is held in check
St. Jude Children's Research Hospital scientists have mapped the structural details of how p53 attaches to its regulatory protein, called BCL-xL, in the cell. The protein p53 is a key activator of the cell's protective machinery against genetic damage, such as the mutations that drive cancer cells' explosive growth.

Genetic tracking identifies cancer stem cells in human patients
The gene mutations driving cancer have been tracked for the first time in patients back to a distinct set of cells at the root of cancer -- cancer stem cells. The international research team, led by scientists at the University of Oxford and the Karolinska Institutet in Sweden, studied a group of patients with myelodysplastic syndromes -- a malignant blood condition which frequently develops into acute myeloid leukemia. The researchers say their findings offer conclusive evidence for the existence of cancer stem cells.

The overall quality of death of cancer patients who die in an urban Canadian setting with ready access to palliative care was found to be good to excellent in the large majority of cases, helping to dispel the myth that marked suffering at the end of life is inevitable.

Getting chemo first may help in rectal cancer

Cancer's potential on-off switch
A team of Boston University School of Medicine researchers have proposed that an 'on and off' epigenetic switch could be a common mechanism behind the development of different types of cancer. Epigenetics is the phenomena whereby genetically identical cells express their genes differently, resulting in different physical traits. Researchers from the Boston University Cancer Center recently published two articles about this in Anticancer Research and Epigenomics.

Learning from sharks
Genetically engineered antibodies are deployed successfully in cancer diagnostics and therapy. Therapeutic antibodies against Alzheimer's disease and multiple sclerosis are currently under development. An important criterion when designing suitable antibody fragments is their stability. Comparing the antibodies of sharks with those of humans, a team of researchers at the Technische Universitaet Muenchen and the Helmholtz Zentrum Muenchen discovered stabilizing mechanisms that can also be applied to optimize custom-tailored antibodies for medical applications.

Cancer patient demands rarely lead to unnecessary tests and treatments
Despite claims suggesting otherwise, inappropriate cancer patient demands are few and very rarely lead to unnecessary tests and treatments from their health care providers, according to new results from a study that will be presented by researchers in the Abramson Cancer Center and the Perelman School of Medicine at the University of Pennsylvania during the annual meeting of the American Society of Clinical Oncology in Chicago in early June.

Researchers propose treating prison population to fight US hepatitis C epidemic
Nearly four million Americans may be infected with the hepatitis C virus, with many people unaware of their status. The virus can take decades to make those infected ill with cirrhosis, cancer or liver failure. Three researchers argue in the May 15 issue of the New England Journal of Medicine that America's oversized prison population provides a critical opportunity to tackle the US hepatitis C epidemic. One in six prisoners is infected with the virus.

New way to predict response to chemo in triple-negative breast cancer

The data are being presented at the ASCO Annual Meeting.

Study shows breastfeeding, birth control may reduce ovarian cancer risk in women with BRCA mutations
Breastfeeding, tubal ligation -- also known as having one's 'tubes tied' -- and oral contraceptives may lower the risk of ovarian cancer for some women with BRCA gene mutations, according to a comprehensive analysis from a team at the University of Pennsylvania's Basser Research Center for BRCA and the Abramson Cancer Center. The findings, a meta-analysis of 44 existing peer-reviewed studies, are published in the Journal of the National Cancer Institute.

Male infertility: It's all about the package
Infertility is generally thought of as a woman's problem. In fact, more than 3 million men across America also experience it. Today, researchers from Cold Spring Harbor Laboratory (CSHL) describe a key event during sperm development that is essential for male fertility. A team led by CSHL professor Alea Mills explains how a protein controls DNA packaging to protect a man's genetic information.

Researchers identify link between colon cancer and metabolism
Rather than the typical series of oxidative steps that take place in the citric acid cycle, cancer cells metabolize sugar via the glycolytic pathway irrespective of whether oxygen is present or not. In The EMBO Journal, researchers in the United States report that the reason for this difference in colon cancer is changes in the Wnt signaling pathway, an essential communication pathway operating in these tumors.
