Source of crucial immune cell in the skin discovered
Identification of precursor cell may lead to tumor immunotherapy as well as new treatment for rare disorder.   view more (2006-01-30)

Tumor wizardry wards off attacks from the immune system
Like the fictional wizard Harry Potter, some cancerous tumors seem capable of wrapping themselves in an invisibility cloak. Researchers at Washington University School of Medicine in St. Louis have found that pancreatic tumors hide from the body's immune surveillance by surrounding themselves with... view more (2006-07-17)

Mechanism in cells that generate malignant brain tumors may offer target for gene therapy
Researchers at Cedars-Sinai Medical Center's Maxine Dunitz Neurosurgical Institute who first isolated cancer stem cells in adult brain tumors in 2004 have now identified a molecular mechanism that is involved in the development of these cells from which malignant brain tumors may originate.   view more (2008-10-27)

Loss of caspase-8 makes neuroblastoma more aggressive
The caspase-8 gene plays a critical role in suppressing metastasis (spread) of neuroblastoma, and the expression of this gene is frequently absent in cancer cells that are aggressively metastasizing.   view more (2006-01-06)

Effective cancer immune therapy through order in the blood vessels
Immune therapies are considered very promising in cancer medicine: Tumor-fighting immune cells are supposed to invade tumor tissue and eliminate cancer cells right there.   view more (2008-04-22)

Sidestepping cancer's chaperone
Cancerous tumors are wildly unfavorable environments. Struggling for oxygen and nutrients while being bombarded by the body's defense systems, tumor cells in fact require sophisticated adaptations to survive and grow.   view more (2007-10-22)

A new mathematical formula for cancer progression
Tumor progression can now be mapped less to mathematical standards and more to individual patients according to a new study by researchers at Harvard and Johns Hopkins Universities.   view more (2007-11-09)

Common viruses may cause cancer
In some cases, the fusion of human cells is a normal process that leads, for instance, to the formation of muscle and bone. Viral infections can also cause cell fusion, but cells fused by viruses are widely considered to be harmless because they are generally believed to die without consequences... view more (2005-11-09)

MicroRNAs as tumor suppressors
In the May 1st issue of G&D, Drs. Yong Sun Lee and Anindya Dutta (UVA) reveal that microRNAs can function as tumor suppressors in vitro.   view more (2007-04-16)

New method to inhibit growth of tumor cells
A new and promising way to inhibit the growth of tumor cells is the result of a collaborative effort between researchers Lars-Ã"¦ke Fransson and Mattias Belting at Lund University and a team in La Jolla, USA, led by cancer researcher Jeffrey Esko. Their work involves hampering the production... view more (2001-12-21)

Does natural selection drive the evolution of cancer?
The dynamics of evolution are fully in play within the environment of a tumor, just as they are in forests and meadows, oceans and streams. This is the view of researchers in an emerging cross-disciplinary field that brings the thinking of ecologists and evolutionary biologists to bear on cancer... view more (2006-11-20)

FOXO factor promotes survival of oxygen-deprived cancer cells
Scientists report that an evolutionarily conserved transcription factor may have both positive and negative effects on the growth of tumors, depending on whether or not the tumor cells have enough oxygen.   view more (2007-12-28)

A novel mechanism of action for anti-tumor agent, CA4P
Anti-angiogenic agents have been successful in the clinic for blocking the growth of solid tumors. However, these agents used in combination with chemotherapy have improved the survival of patients with cancers by only several months.   view more (2005-10-07)

Refusal of suicide order: Why tumor cells become resistant
Cells with irreparable DNA damage normally induce programmed cell death, or apoptosis. However, this mechanism often fails in tumor cells so that transformed cells are able to multiply and spread throughout the body.   view more (2008-06-24)

Protein holds back growth of head and neck tumors
A protein associated with the growth of head and neck tumors may be a tumor suppressor that could prevent the spread of cancer when it is expressed above normal levels.   view more (2006-02-01)

Obesity drug helps unlock clues about cancer
An approved drug for fighting obesity is helping scientists at Wake Forest University School of Medicine uncover clues about how to stop the growth of cancerous tumors.   view more (2007-02-02)

Cancer stem cells spur glioma Angiogenesis, could hold key to brain tumor therapy
Stem cell-like glioma cancer cells that share many characteristics with normal stem cells propel the lethal growth of brain cancers by promoting tumor blood vessel formation, and may hold the key to treating these deadly cancers.   view more (2006-08-15)

New evidence supports century-old theory of cancer spread
A Yale School of Medicine study in the December issue of Lancet Oncology challenges mainstream oncology researchers to consider tumor cell hybridization with white blood cells as a major reason that cancer metastasizes or spreads to other parts of the body.   view more (2005-12-13)

A genetic factor predicts prognosis in brain tumor patients
PLoS ONE has just published a study which defines a gene locus on chromosome 1 that predicts prognosis of brain tumor patients and may even set the basis for the development of more efficient drugs to combat brain cancer.   view more (2007-06-28)

Innovative movies show real-time immune-cell activity within tumors
Using advanced new microscopy techniques in concert with sophisticated transgenic technologies, scientists at The Wistar Institute have for the first time created three-dimensional, time-lapse movies showing immune cells targeting cancer cells in live tumor tissues.   view more (2006-11-21)

A fisheye view of the deadliest breast cancer
Inflammatory breast cancer (IBC) is the deadliest form of the disease, with fewer than half of those diagnosed today having a five-year prognosis for survival.   view more (2006-12-13)

MIT sheds light on how tumor cells form
MIT cancer researchers have discovered a process that may explain how some tumor cells form, a discovery that could one day lead to new therapies that prevent defective cells from growing and spreading.   view more (2006-06-22)

Tumor-killing virus selectively targets diseased brain cells
New findings show that a specialized virus with the ability to reproduce its tumor-killing genes can selectively target tumors in the brains of mice and eliminate them.   view more (2008-02-20)

MRI drug may improve cancer-killing ability of chemotherapy, study says
A contrast agent currently used in magnetic resonance imaging (MRI), called mangafodipir, may increase the cancer-killing ability of some chemotherapy drugs while protecting normal cells.   view more (2006-02-15)

MU researcher links hormone replacement therapy to breast cancer
Millions of post-menopausal women use hormone replacement therapy (HRT) as a method to reduce symptoms associated with menopause. In a recent University of Missouri study, researchers found that one of the hormones used in HRT, a synthetic progestin, could be a major factor in promoting breast... view more (2008-04-02)
