An engineered virus that tracks down and compels cancer cells to eat themselves

An engineered virus tracks down and infects the most common and deadly form of brain cancer and then kills tumor cells by forcing them to devour themselves, researchers at The University of Texas M. D. Anderson Cancer Center report.

Gene therapy approach used in creating new arteries for older patients does not appear to cause cancer

"This result is an encouraging step along the road to new tissues for patients to replace those that have failed or have been destroyed due to trauma or disease," she said.

Monotherapy phase I clinical trials of novel cytotoxics, targeted therapeutics, antimetastatic agents/angiogenesis inhibitors, and immunotherapeutics/vaccines

Numerous novel oncology agents are currently in phase I monotherapy trials. New Medicine's Oncology KnowledgeBASE (nm|OK) has updated the records of 92 such agents with preclinical or clinical results reported during the 2005 meetings of the American Association for Cancer Research (AACR)

DNA end caps may lead to cancer treatments

The two ends of human DNA have different structures that are treated differently as a cell divides, UT Southwestern Medical Center researchers have found in a study that could help lead to cancer therapies.

Scientists have determined the detailed structure of an essential piece of the telomerase enzyme

Scientists have determined the detailed structure of an essential piece of the telomerase enzyme, an important contributor to the vast majority of human cancers. Understanding the physical shape of the protein has led to a better understanding of how it acts to immortalize cells - and should help scientists design broadly effective cancer drugs.

Simple urine test detects bladder cancer

According to Italian researchers a simple and accurate urine test can detect bladder cancer early and they say the test should be used on smokers and others prone to the disease.

Measurement of telomerase activity in urine appears useful for detection of bladder cancer in men

The incidence of human bladder cancer has greatly increased over the last few decades, with more than 60,000 new cases diagnosed each year in the United States alone, and now represents the 4th most common malignancy in men and the 10th most common in women, according to background information in the article.

Compound called GRN163L blocks lung cancer

Researchers at UT Southwestern Medical Center have found a compound that shows promise as a way to block the spread, or metastasis, of lung cancer.

Placental tissue could feasibly provide an abundant source of cells with the same potential to treat diseases as embryonic stem cells

Routinely discarded as medical waste, placental tissue could feasibly provide an abundant source of cells with the same potential to treat diseases and regenerate tissues as their more controversial counterparts, embryonic stem cells, suggests a University of Pittsburgh study to be published in the journal Stem Cells and available now as an early online publication in Stem Cells Express.

Discovery may lead to new therapies for leukemia

Researchers from the University of Pennsylvania School of Medicine found that a protein called NF-Ya activates several genes known to regulate the development of hematopoietic stem cells (HSC), or blood-producing stem cells, in bone marrow.

U.S. scientists have successfully engineered blood vessels from human vascular cells in the lab

Tissue engineering has made considerable progress in the past decade, but advances have stopped short of clinical application for most tissues. For elderly patients tissue-engineered arteries could provide grafts for bypass surgery.

Arteries bio-engineered from elderly cells

Researchers from Duke University's Medical Center and Pratt School of Engineering have demonstrated that they can grow new human blood vessels from cells taken from patients who especially need such assistance – older adults with cardiovascular disease.

Bio-engineered skin provides clues to melanoma development

When it comes to the deadly skin cancer melanoma, studying functional tissue rather than cell lines may better provide insight into the disease's development, according to new research from a Howard Hughes Medical Institute predoctoral fellow at Stanford University School of Medicine.

Stem cells from adults may cause cancer

Stem cells, often lauded as future cures for numerous diseases, are immature "master" cells that can be programmed to become many kinds of tissue, but experts have known for a long time that stem cells harvested from embryos can turn cancerous and have been linked to leukaemias and breast cancer.

Ancient protein could be critical to stopping the uncontrolled division of tumor cells that cause cancer

Molecular Biology and Microbiology professor Mark Muller has found that the protein, called MKRN1, promotes the destruction of an enzyme called telomerase that enables rapid duplication of cells. While researchers have known for years that healthy cells repress telomerase, they haven't understood why.

Scientists identify novel regulator of telomere homeostasis

Each of our 46 chromosomes is capped by a telomere – a long stretch of repeated DNA (TTAGG). Telomeres play a key protective function in our cells, and now Dr. In Kwon Chung and colleagues at Yonsei University (Seoul, Korea) and the University of Central Florida reveal a novel mechanism to modulate telomere length.

Telomerase finding has major implications for cancer

UCLA biochemists have determined the three-dimensional structure of a major domain of telomerase, the enzyme that helps maintain telomeres - small pieces of DNA on the ends of chromosomes that act as protective caps - allowing DNA ends to be copied completely when cells are replicated.

Two chemicals boost immune cells' ability to fight HIV without gene therapy

A UCLA AIDS Institute study has discovered that two chemical compounds may help the immune systems of HIV-infected persons fight the disease without invasive gene therapy.

Study provides insight into strategies for telomere-based molecular cancer therapeutics

A new study published in the January issue of Cancer Cell provides exciting new information about how to boost the effectiveness of a promising cancer treatment that targets telomeres in an attempt to interfere with the ability of a cancer cell to continuously divide.

Genetic mutations and cellular modifications may provide clues to the associations between slight genetic abnormalities and often fatal diseases

Modern research is delving deep into the human genome to find the answers to medical mysteries and, hopefully, cures for the most deadly diseases. According to four new studies presented during the 46th Annual Meeting of the American Society of Hematology
