How is H pylori adhesion to gastric cells associated with MUC1 mucin VNTR size?

The Gram negative bacterium H pylori is involved in the pathogenesis of several gastrointestinal diseases, ultimately leading to gastric carcinoma.

Modified virus vaccine shows promise in mouse model of breast cancer

Researchers have shown that vaccinating mice with a modified form of a virus containing proteins from breast cancer cells can kill large breast cancer tumors and tumors that have spread to the lungs.

Cancer drug allergies

Cancer patients from the Southeastern United States who are treated with the drug cetuximab, known commercially as Erbitux, are far more likely to suffer severe allergic reactions than patients in other regions of the country.

Researchers find cause of severe allergic reaction to cetuximab

Clinicians have been perplexed by the fact that some patients given the drug cetuximab - an immune-based therapy commonly used to treat persons diagnosed with head and neck cancer, or colon cancer - have a severe and rapid adverse reaction to the drug.

Curing cancer with natural products - a case for shamans and herb women?

Not at all, for many chemotherapies to fight cancer applied in modern medicine are natural products or were developed on the basis of natural substances. Thus, taxanes used in prostate and breast cancer treatment are made from yew trees. The popular periwinkle plant, which grows along the ground of many front yards, is the source of vinca alkaloids that are effective, for example, against malignant lymphomas. The modern anti-cancer drugs topotecan and irinotecan are derived from a constituent of the Chinese Happy Tree.

Neural progenitor cells as reservoirs for HIV in the brain

Impaired brain function is a prominent and still unsolved problem in AIDS.

Watery pools in bone marrow key to psoriatic arthritic damage

Researchers have learned more about how a leading drug prevents certain types of arthritis from eating away at bone, according to a study published in the March edition of the Annals of the Rheumatic Diseases.

Preclinical antitumor efficacy evaluation of dendrimer-based methotrexate conjugates

Although a variety of nanoparticles continue to show promise for improving cancer imaging and therapy, regulators and drug developers are concerned that these delivery systems may prove difficult to manufacture on a consistent basis, which is key for any agent designed for use in humans.

Protein that stimulates blood vessel growth worsens ovarian cancer

A protein that stimulates blood vessel growth worsens ovarian cancer, but its production can be stifled by a tiny bit of RNA wrapped in a fatty nanoparticle, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center reports in the Journal of the National Cancer Institute.

Stem cell therapy studies for stroke, cerebral palsy prepare for clinical trials

Finding answers about optimal dosage and timing for stem cell therapy in adults with strokes and newborns with ischemic injuries is a goal of two new federally funded studies.

Genetic evolution of tumours according to their growth dynamics.

A study co-directed by the Universidad Complutense de Madrid and La Paz hospital in Madrid identifies a protein of high expression in cells located at the tumour boundary that could play an essential role in the evolution of tumours and their invasive potential.

Discovery of 480 genes that control human cell division

A team of U.S., Israeli and German scientists used computational biology techniques to discover 480 genes that play a role in human cell division and to identify more than 100 of those genes that have an abnormal pattern of activation in cancer cells.

8 Jan 2008

Cancer cell line developed that is resistant to new cancer therapy

A cancer cell line that is resistant to one of the newest classes of cancer treatments has been developed by researchers who already are using it to determine what else to give patients when this happens.

Research may lead to more effective sunscreens

Chronic exposure to the sun increases the risk of an individual developing skin cancer because UV light from the sun can cause genetic mutations that enable cells in the skin to grow in an uncontrolled manner.

Stem-cell finding alters ethical controversy

When University of Wisconsin-Madison researchers succeeded in reprogramming skin cells to behave like embryonic stem cells, they also began to redefine the political and ethical dynamics of the stem-cell debate, a leading bioethicist says. R. Alta Charo, a UW-Madison professor of law and bioethics, says the scientific finding could have far-reaching effects on the social dimensions of the ongoing controversy over embryonic stem cell research.

Hormone norepinephrine may hasten the progression of certain blood cancers

Researchers here have shown that in cell cultures, the stress hormone norepinephrine appears to promote the biochemical signals that stimulate certain tumor cells to grow and spread.

Human embryonic stem cells derived from preimplantation genetically diagnosed embryos

A human stem cell line derived from embryos that were identified by preimplantation genetic diagnosis (PGD) to carry the mutation for fragile X syndrome has provided an unprecedented view of early events associated with this disease.

Zinc transporters regulate pancreatic cancer

Zinc, an important trace element for healthy growth and development, can be related to pancreatic cancer. Too much ZIP4, a molecule that enables the transport of zinc into cells, promotes the growth and spread of pancreatic tumors cells, said a group of researchers from Baylor College of Medicine in Houston, The University of Texas M.D. Anderson Cancer Center and the University of Florida in Gainesville, in a report which appears online today in the Proceedings of the National Academy of Sciences.
