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.

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.

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
Researchers from University Hospitals Case Medical Center's Seidman Cancer Center and Case Western Reserve University School of Medicine will present findings from a study that found the presence of tumor-infiltrating lymphocytes, a type of white blood cell, ahead of treatment may help predict response to platinum-based chemotherapy in women with triple-negative breast cancer. The data are being presented at the ASCO Annual Meeting.

Large panel genetic testing produces more questions than answers in breast cancer
While large genetic testing panels promise to uncover clues about patients' DNA, a team of researchers from Penn Medicine's Abramson Cancer Center has found that those powerful tests tend to produce more questions than they answer.

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.

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.

Novel target found for chemotherapy-resistant leukemia cells

MEMS nanoinjector for genetic modification of cells
The ability to transfer a gene or DNA sequence from one animal into the genome of another plays a critical role in a wide range of medical research -- including cancer, Alzheimer's disease, and diabetes, and now there's a way to avoid cell death when introducing DNA into egg cells. In Review of Scientific Instruments, the team describes its microelectromechanical system nanoinjector, which was designed to inject DNA into mouse zygotes.

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.

New agent may enhance effectiveness of radiotherapy
Scientists from The University of Manchester -- part of the Manchester Cancer Research Centre -- have demonstrated the potential of a drug to improve the effectiveness of radiotherapy in stopping tumor growth. There is increasing interest in using the body's own immune system to attack tumor cells -- a strategy that can be very effective without the side effects associated with conventional chemotherapy.

Dartmouth scientists identify genetic blueprint for cancerous tumors of the appendix
Using next generation DNA sequencing, Dartmouth scientists have identified potentially actionable mutations in cancers of the appendix. Their study, 'Molecular Profiling of Appendiceal Epithelial Tumors Using Massively Parallel Sequencing to Identify Somatic Mutations,' was published in the journal Clinical Chemistry today. When specific mutations for a cancer type are identified, patients can be treated with chemotherapy or other targeted agents that work on those mutations.
