Apoptosis is programmed cell death, the body's normal method of disposing of damaged, unwanted, or unneeded cells.

Scientists discover new approach for treating virus-induced lymphomas

Kaposi's sarcoma herpesvirus (KSHV) is a human tumor virus and an etiological agent for Kaposi's sarcoma and primary effusion lymphoma (PEL). PELs are aggressive lymphomas with reported median survival time shorter than six months after diagnosis.

New anti-cancer target in enzyme MAP4K3

Scientists working at the Institute for Cancer Research have found a new anti-cancer target in MAP4K3, an enzyme which is able to 'switch on' the growth-promoter mTOR.

Two novel therapies for multiple myeloma

Two novel biologics are currently being investigated for their potential benefit to multiple myeloma patients in separate ongoing clinical trials at NewYork-Presbyterian Hospital/Weill Cornell Medical Center.

Inhaled Celecoxib shows new promise for lung cancer treatment

In recent years, Cycloxygenase (COX)-2 has emerged as a therapeutic target for the prevention and treatment of various types of cancers.

Green tea and COX-2 inhibitors combine to slow growth of prostate cancer

Drinking a nice warm cup of green tea has long been touted for its healthful benefits, both real and anecdotal. But now researchers have found that a component of green tea, combined with low doses of a COX-2 inhibitor, could slow the spread of human prostate cancer.

Scientists alter electrical properties of cells inducing regeneration

Scientists at Forsyth may have moved one step closer to regenerating human spinal cord tissue by artificially inducing a frog tadpole to re-grow its tail at a stage in its development when it is normally impossible. Using a variety of methods including a kind of gene therapy, the scientists altered the electrical properties of cells thus inducing regeneration.

Aspirin offers help for Barrett's esophagus

Researchers at Fred Hutchinson Cancer Research Center have found that people with the most-aggressive form of Barrett's esophagus, a precancerous condition that can lead to esophageal cancer, may benefit the most from preventive therapy with aspirin, ibuprofen and other nonsteroidal anti-inflammatory drugs, or NSAIDs.

New understanding of how and why Taxol works in patients with breast cancer

Cancer researchers at Georgetown University Medical Center have taken a step towards understanding how and why a widely used chemotherapy drug works in patients with breast cancer.

Watercress shows anti-cancer potential

Eating watercress daily can significantly reduce DNA damage to blood cells, which is considered to be an important trigger in the development of cancer, University of Ulster scientists revealed.

HIV protein TAT used to pull protein Bim into cancer cells - helps kill cancer cells

Cancer cells are sick, but they keep growing because they don't react to internal signals urging them to die. Now researchers at Washington University School of Medicine in St. Louis have found an efficient way to get a messenger into cancer cells that forces them to respond to death signals. And they did it using one of the most sinister pathogens around - HIV.

Variation in gene caspase-8 may help protect against breast cancer

A large-scale analysis of data on breast cancer risk has concluded that a common variation in the gene caspase-8 (CASP8) is associated with a somewhat lower risk of the disease. Variants are small changes that occur in a gene sequence.

Ceramide plays big role in embryonic development

A little-known lipid plays a big role in helping us grow from a hollow sphere of stem cells into human beings, researchers have found.

New testing approach to predict outcome in patients with bladder cancer

A new testing approach has been shown to be effective in identifying patients at the highest risk of cancer relapse after surgery for bladder cancer, say researchers in the February issue of The Lancet Oncology.

Dendrimer-based targeted delivery of an apoptotic sensor in cancer cells

Taking a critical step toward the development of a multifunctional nanoscale anticancer agent that can detect cancer, treat it, and then report on the success or failure of that treatment, investigators at the University of Michigan have developed a nanoscale sensor of cell death.

Nanoparticles yield delivery tools for therapeutic nucleic acids

Cancer researchers hold great hope that nucleic acid-based therapeutics, such as anticancer genes, antisense oligonucleotides, and small interfering RNA (siRNA) molecules, will prove to be powerful antitumor agents.

Fat-hormone leptin may enhance the growth of colonic cancers

Tests on three human colon cancer cell lines showed that the fat-hormone 'leptin' may enhance the growth of colonic cancers. This finding could show why obese people are at increased risk of colon cancer.

Optical and magnetic resonance imaging of cell death and platelet activation using annexin A5-functionalized quantum dots

By combining a quantum dot with a novel carrier of the magnetic resonance imaging (MRI) agent gadolinium, a team of investigators at the University of Maastricht, in The Netherlands, has developed a nanoparticle that can spot apoptosis, or programmed cell death, using both MRI and fluorescence imaging.

Experimental drug provides powerful therapy against acute myeloid leukemia

Researchers at The University of Texas M. D. Anderson Cancer Center have found, in laboratory studies, that the experimental drug ABT-737 which has shown promise in some cancers, can destroy acute myeloid leukemia (AML) blast, progenitor and even stem cells that are often resistant to standard chemotherapy treatment.

Evolution is driving therapeutic resistance to cancer therapies

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.

Lifestyle decisions that may stave off onset of cancer

Personal choices, such as smoking and consumption of fatty foods, have long been linked to increased cancer risk. During recent years, scientists have been seeking to isolate a variety of lifestyle decisions that may stave off the onset of cancer or even reduce tumor formation in their early stages.
