Plant stem cell breakthrough made

Totipotent stem cells allow plants to build new organs throughout their whole life. But it has been unclear how hormones and genetic factors work together to prevent plants from having growth that is either stunted, or uncontrolled and tumor-like. Scientists from the Max Planck Institute for Developmental Biology have now uncovered a feedback mechanism, involving a growth-enhancing hormone and a regulatory protein, which controls the number of stem cells the plant produces.

Targeted cancer therapies: Another step forward

While it is clear that the treatment of cancer has already begun to undergo a paradigm shift with the inclusion of innovative targeted therapies into current regimens, it would be wrong to assume these products will entirely replace traditional chemotherapy as the standard treatment for cancer sufferers.

Imatinib mesylate (Gleevec) may not be effective at treating kidney cancer

Mayo Clinic Cancer Center investigators report that imatinib mesylate (GleevecTM), the drug used to treat patients with gastrointestinal stromal cancers (GISTs), is not likely to be effective for patients with high grade renal cell carcinoma -- the most aggressive kidney cancer.

Children could be saved from neuroblastoma using antibody therapy

Combination of T cell, antibody to neuroblastoma cells and molecule that spurs T cell growth is designed to treat low initial tumor levels or small cancer cell populations that survive initial treatment, according to St. Jude.

The role of genes in the development of non-Hodgkin's lymphomas

An international consortium of epidemilogists - including Dr. Alexandra Nieters and Professor Nikolaus Becker of the Clinical Epidemiology Division of the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) - has conducted the first ever investigation of genetic factors in the development of non-Hodgkin’s lymphoma (NHL) in a study called InterLymph.

Kids with specific gene variant more at risk from passive smoking

When U.S. children who possess a variant gene are exposed to second-hand smoke in their homes, they are at a substantially greater risk for developing respiratory illnesses that lead to school absences.

Researchers discover potential mechanism for tumor growth

Researchers at Columbia University Medical Center have identified an inherent feature of stem and progenitor cells that may promote initiation and progression of cancerous tumors.

Aromatase inhibitors may slow growth of lung cancer

A few years ago researchers discovered that, much like breast tumors, some lung tumors also thrive on estrogen. Now a medical student conducting research on a Howard Hughes Medical Institute (HHMI) fellowship and colleagues have managed to stop the growth of human lung cancer cells in mice with a class of breast cancer drugs called aromatase inhibitors.

Finding how water channels - aquaporins - open and close may lead to new drugs

Living organisms are dependent on being able to adjust the water content in their cells. This is achieved by regulating the flow of water through the cell membrane.

Cancer road map shows how cancer spreads

Scientists at Cornell University in New York have discovered how cancer spreads from a primary site to other places in the body.

Study suggests a way to eliminate glioblastoma

Scientists have devised a strategy to treat tumors by selectively targeting and killing the malignant cells. A new preclinical study, published in the open access journal PLoS Medicine, has applied the approach to combat glioblastoma multiforme (GBM).

Liver plays crucial role in iron metabolism

A new study in the December Cell Metabolism reveals an unexpected connection between a tumor suppressor gene in the liver and the normally careful control over the amount of iron absorbed from the diet.

Stem cells may cause some forms of bone cancer

The researchers are the first to identify a population of cells with characteristics of adult and embryonic stem cells in cultures derived from biopsies of patients' bone tumors. They describe their findings in the medical journal Neoplasia.

Role of melatonin for the treatment of cancer increasing in improtance

Researchers say that the results are so compelling that cancer funding agencies should be eager to support clinical trials to evaluate its therapeutic role in a variety of cancers.

Ack1 molecule stimulates the aggressive growth of prostate cancer

The molecule, Ack1, a member of the growth-promoting tyrosine kinase gene family, stimulates tumor formation in part by signaling prostate cells to rid themselves of a tumor-suppressor protein. Normally, this suppressor protein would inhibit rapid cell growth by signaling the cell to destroy itself.

Aldosterone shows promise as stroke treatment

A bi-polar hormone that can contribute to strokes and minimize their damage is emerging as a therapeutic target in the battle against these brain attacks, researchers say.

Phenoxodiol - docetaxel combination for women with recurrent ovarian cancer

A clinical study of ovarian cancer initiated by investigators at Yale School of Medicine will combine the anti-cancer drug phenoxodiol with docetaxel for women with recurrent ovarian cancer.

Researchers move in on novel therapeutics to inhibit melanoma

Northwestern University researchers have developed a novel, three-dimensional model that allows scientists to observe how interacting with the microenvironment of metastatic melanoma cells induces normal skin cells to become similar to aggressive cancer cells that migrate and spread throughout the body.

Unexpected link between muscular dystrophy and muscle wasting associated with cancer

A new study provides important insight into the mechanisms of a muscle wasting disorder that interferes with treatment for cancer and has a negative impact on patient survival.
