New understanding of how a mole develops into melanoma

Researchers have discovered how a mole develops into melanoma by showing the interaction of two key proteins involved in 60-70 percent of tumors. The Penn State scientists also demonstrate that therapeutic targeting of these proteins is necessary for drugs to effectively treat this deadly form of cancer.

Researchers find way to make tumor cells more sensitive to hyperthermia-enhanced radiation therapy

Tumors have a unique vulnerability that can be exploited to make them more sensitive to heat and radiation, researchers at Washington University School of Medicine in St. Louis report.

Whole-organ genomic survey depicts journey from normal to malignant cell

Whole-organ maps that superimpose genetic information over the terrain of cancerous bladders chart the molecular journey from normal cell to invasive cancer, an international research team led by scientists at The University of Texas M. D. Anderson Cancer Center reports online at the journal Laboratory Investigation.

New understanding of colon tumor development

Recent work from the Finnish Academy Center of Excellence on Cancer Biology at the University of Helsinki, Finland, has shed light on the mechanisms of colon tumor development and may help to design better treatment for this disease.

Cells lining milk ducts hold key to spread of ductal carcinoma in situ

When a form of cancer that begins in the milk ducts of the breast invades neighboring tissue to spread to other parts of the body, the cause lies not in the tumor cells themselves but in a group of abnormal surrounding cells that cause the walls of the duct to deteriorate like a rusty pipe, according to a new study led by Dana-Farber Cancer Institute researchers.

Epidermal growth factor receptor protects cancer cells from starving

A growth factor receptor found abundantly on the surface of cancer cells and long known to fuel cancer growth also protects tumor cells from starvation by a newly identified mechanism, researchers at The University of Texas M. D. Anderson Cancer Center report in the May 5 issue of Cancer Cell.

Stanford researchers synthesize new agents to flush HIV out of hiding

Any hunter will tell you that when your quarry goes into hiding, you have to flush it out to get a good shot at it. Such is the case with HIV, the virus that causes AIDS.

Novel automated anesthetic technique

Researchers at McGill University and the McGill University Health Centre (MUHC) have performed the world's first totally automated administration of an anesthetic. Nicknamed "McSleepy," the new system developed by the researchers administers drugs for general anesthesia and monitors their separate effects completely automatically, with no manual intervention.

New study raises questions about prostate cancer therapies targeting insulin-like growth factor receptor

Therapies under development to treat prostate cancer by inhibiting the ability of insulin-like growth factor (IGF-1) to activate its target receptor could have unexpected results especially if a major tumor suppressor gene - p53 - is already compromised, according to new research by investigators at Fred Hutchinson Cancer Research Center.

Small molecule nutlin-3a activates an important cancer suppressor gene

By activating a cancer suppressor gene, a small molecule called nutlin-3a can block cancer cell division, according to researchers at the National Cancer Institute (NCI), part of the National Institutes of Health.

Researchers create heart and blood cells from reprogrammed skin cells

Stem cell researchers at UCLA were able to grow functioning cardiac cells using mouse skin cells that had been reprogrammed into cells with the same unlimited properties as embryonic stem cells.

Study describes mechanism linking acohol with risk of breast cancer

The known association of alcohol consumption with an increased risk of breast cancer has been linked by researchers at the University at Buffalo to a process that causes genes that promote normal cell growth to produce proteins that precipitate unregulated cell growth, an action known as hypermethylation

New concept sends medical images via cellular phones

A process to transmit medical images via cellular phones that has been developed by a Hebrew University of Jerusalem researcher has the potential to provide sophisticated radiological diagnoses and treatment to the majority of the world's population lacking access to such technology.

Medicare costs estimated at $21.1 billion for 5 years of care for elderly cancer patients

The cost of cancer care for elderly Medicare patients varies by tumor type, stage at diagnosis, phase of care, and survival, according to a new study published online April 29 in the Journal of the National Cancer Institute.

Getting to the roots of breast cancer

The lesson learned in eradicating dandelions from your yard could apply in treating breast cancer as well, said researchers from Baylor College of Medicine in Houston in a report that appears online today in the Journal of the National Cancer Institute.

Yale scientists explain metastasis

Metastasis, the spread of cancer throughout the body, can be explained by the fusion of a cancer cell with a white blood cell in the original tumor, according to Yale School of Medicine researchers, who say that this single event can set the stage for cancer's migration to other parts of the body.

Brain tumor surgery, depression and survival

Depression is one of the most common psychiatric disorders in the world today. It is estimated that in any given year, 5 to 9 percent of the US population is clinically depressed. Studies have shown that depression negatively affects the immunological system, alters the body's response to malignancy, and may influence behavioral factors that impact recovery from disease

Biomarkers identified for idiopathic pulmonary fibrosis

The first evidence of a distinctive protein signature that could help to transform the diagnosis and improve the monitoring of the devastating lung disease idiopathic pulmonary fibrosis (IPF) is being reported by University of Pittsburgh School of Medicine researchers in this month's edition of PLoS Medicine, an open-access journal of the Public Library of Science.

Researchers identify new genes that help predict breast cancer outcomes

Not a day goes by without a new story about the environment. Although we often consider the environment on a global scale, cells in our body also have to contend with environmental factors.
