New discovery on programmed cell death

Investigators at St. Jude Children's Research Hospital have discovered a dance of proteins that protects certain cells from undergoing apoptosis, also known as programmed cell death. Understanding the fine points of apoptosis is important to researchers seeking ways to control this process.

New genetic link to schizophrenia

Schizophrenia emerges from an altered pattern of brain development, and researchers continue to search for the genes that cause the brain to develop along a path that ultimately leads to schizophrenia.

Potential novel class of drugs for treating heart attacks and stroke

A new compound that blocks an early step in cell death could lead to a novel class of drugs for treating heart attacks and stroke.

Discovery of protein that stops the growth of melanomas

One might call it a tale of two melanocytes. Given the same genetic mutation, why does one melanocyte shut down growth and become a relatively benign mole, while another rages out of control and develops into deadly melanoma"

Scientists focus on Epstein-Barr virus

Epstein-Barr virus (EBV) is a human-pathogenic virus which belongs to the herpes virus family.

Genomic screen identifies 273 human proteins required for HIV propagation

In some ways, HIV resembles a minimalist painter, using a few basic components to achieve dramatic effects.

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.

The drug sirolimus shrinks tumors, improves lung function

The drug sirolimus, normally used to help transplant patients fight organ rejection, may eventually be used as a less invasive treatment for a tumor called angiomyolipomata in patients with who would otherwise face surgery.

Two genes are important key to regulating immune response

A research team at Weill Cornell Medical College in New York City has identified two genes that may be crucial to the production of an immune system cytokine called interleukin-10 (IL-10)

New information about how normal cells and cancer cells survive under stress

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.

Complex path to cell death shown by identification of new genes

Can a tiny winged insect's salivary glands really tell us about processes relevant to human disease? Yes, according to a new study by researchers at the University of Massachusetts Medical School (UMMS), who gained new insights into autophagy - a cellular degradation process associated with a form of programmed cell death - by studying the salivary gland cells of the fruit fly.

Bortezomib pushes cancer cells into overdrive, so that they self-destruct

University of Michigan Comprehensive Cancer Center researchers have discovered that bortezomib, a promising cancer drug, is able to strike a blow against melanoma tumor cells by revving up the action of a cancer-promoting gene.

How inhibitor-of-apoptosis chemicals kill tumors

Chemical compounds specially designed to neutralize proteins that would otherwise allow tumor cells to cheat death have been recognized for some time by scientists as a promising new avenue for cancer therapy.

New explanation for how regulatory networks of genes evolved

When ancient retroviruses slipped bits of their DNA into the primate genome millions of years ago, they successfully preserved their own genetic legacy.

New finding about the relationship between stress and cancer

One way environmental stress causes cancer is by reducing the activity level of an enzyme that causes cell death, researchers say.

Modified Curcumin demonstrates even greater tumor suppressive properties

Curcumin, the yellowish component of turmeric that gives curry its flavor, has long been noted for its potential anti-cancer properties.

Chlorophyll breakdown in ripening apples and pears produces highly active antioxidants

Fall, the season of colors: Leaves turn red, yellow, and brown. The disappearance of the color green and the simultaneous appearance of these other colors are also signs of ripening fruit.

How tumors respond to EGFR inhibitors

Three papers published this month in the open access general medical journal PLoS Medicine investigate how tumors respond to a an important class of drugs used in cancer chemotherapy, known as epidermal growth factor receptor (EGFR) inhibitors.

Emerging cancer therapies and novel targets

What are the cancer drugs of tomorrow and how will they be developed? At the AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics, researchers will present some answers to these and other pressing questions regarding emerging cancer therapeutics.

Combination targets offer new hope in fight against cancer

While some targeted therapies - drugs developed to attack specific molecules in the critical chemical pathways occurring within cancer cells - work well by themselves, increasingly researchers are finding that they work better when teamed with other targeted and conventional therapies.
