Curry spice appears to shut down a protein active in the spread of breast cancer

Curcumin, the main ingredient of turmeric and the compound that gives curry its mustard-yellow color, inhibits metastasis to the lungs of mice with breast cancer, report researchers at The University of Texas M. D. Anderson Cancer Center

Strain of avian influenza highly resistant to Tamiflu

An avian influenza virus isolated from an infected Vietnamese girl has been determined to be resistant to the drug oseltamivir, the compound better known by its trade name Tamiflu, and the drug officials hope will serve as the front line of defense for a feared influenza pandemic.

Possible explanation for the higher incidence of lung cancer in African Americans

Faulty cell cycle "checkpoints" that fail to respond to DNA damage effectively may contribute to the high incidence of lung cancer in African-Americans, say researchers at Georgetown University's Lombardi Comprehensive Cancer Center and the National Cancer Institute (NCI).

Cell phones speed heart attack treatment

A Michigan hospital has cut in half the time it takes to begin life-saving treatment of heart attack patients by using cell phones to transmit electrocardiograms (ECGs) from the field

E-cadherin, that cellular touch so important in cancer

E-cadherin is a molecule involved in adhesion between epithelial cells that also seems to have a protective role in cancer, since its loss is associated with tumour progression and metastases formation in a series of different cancers.

Alternative methods to create stem cells successful in mice-studies

According to researchers in the U.S. two alternative methods for making embryonic stem cells, work in mice and could lead to a less controversial way to grow them.

Cervical cancer vaccine shows promising results but smear tests still vital

Hopes of an end to routine smear testing have been raised by promising results achieved by a prototype cervical cancer vaccine.

Endocytosis of HIV-1 activates plasmacytoid dendritic cells via toll-like receptor -viral RNA interactions

Progressive disease after HIV infection is inversely correlated with the presence of plasmacytoid dendritic cells (pDCs), a subset of the dendritic cell family and the major producers of type 1 interferon in the body. High numbers of pDCs is related to successful control of HIV.

New public survey on stem cells

Stem cells are unique among human cells in that they possess the uncanny ability to develop into virtually any other cell of the body, offering a hypothetical tool kit for repairing diseased hearts, mending broken spinal cords, or correcting genetic diseases, among other hoped-for benefits.

Discovery of agent that can suppress cancer development

In a case of basic science detective work, researchers at The University of Texas M. D. Anderson Cancer Center have solved the puzzle of the "inconsistent biomarker" and, in the process, may have discovered an agent that can suppress cancer development.

Nanobombs to eradicate cancer

University of Delaware researchers are opening a new front in the war on cancer, bringing to bear new nanotechnologies for cancer detection and treatment and introducing a unique nanobomb that can literally blow up breast cancer tumors.

Bacille Calmette Guerin (BCG) vaccination can protect children from tuberculosis infection as well as active TB disease

There are about 10 million cases of TB globally each year and 1 in 3 people are infected with the TB bacterium. BCG is the most widely used vaccine worldwide, but its mechanism of protection is poorly understood. It is thought to prevent progression of infection to active TB but whether it protects against the acquisition of infection itself has not been investigated in humans.

Why breast black cancer patients experience lower survival rates than other women

Black women with stage I or II breast cancer are more likely than their counterparts of other races to abandon chemotherapy before completing their full course of treatment, according to a recent Columbia University Medical Center study.

Chromosomes in the nucleus of the cell carry the material of heredity, or genes

Abnormal cell division that yields cells with an extra set of chromosomes can initiate the development of tumors in mice, researchers at Dana-Farber Cancer Institute have shown, validating a controversial theory about cancer causation put forth by a scientific visionary nearly 100 years ago.

Personalized medicine to improve the outcome for breast cancer patients

As cancer remains a leading cause of death in the United States, early detection and treatment are critical keys to improving the survival rate. Yet, an individual's response to treatment varies considerably, even among cancers of the same histological type.

Biologists uncover pivotal role of a gene called "Cut"

A DNA-binding protein, Cut interprets and transcribes the developmental signals sent through the "Notch" gene, which regulates a layer of epithelial cells as they replicate and divide. But when Cut garbles those signals the result is uncontrolled cell proliferation, sometimes with dire genetic and health consequences.
