New finding has potentially major implications for anti-angiogenic therapy

Scientists supported by the National Institute of Dental and Craniofacial Research (NIDCR) have added a key new piece to the puzzle of how tumor cells induce new blood vessels to form and fuel their abnormal growth, a well-known process called angiogenesis.

Compound derived from cottonseed could help improve the effectiveness of chemotherapy at treating head and neck cancer

The findings, which appear in the July issue of the journal Molecular Cancer Therapeutics, could lead to a treatment that provides an effective option to surgically removing the cancer, helping patients preserve vital organs involved in speech and swallowing.

Discovery of a chemical messenger called neuropeptide Y (NPY) in taste bud cells

The tongue's ability to differentiate between sweet and bitter tastes may reside in the same taste bud cells, a new study reports.

Asthma may be linked to a decreased risk of brain cancer

According to new research there is a suggestion that gene variants known to raise the risk of asthma, might also decrease the risk of a common type of brain cancer that progresses rapidly and is fatal.

New theory on aging says popping pills and drinking orange juice no guarantee you'll live longer

In direct contrast to previous reports, researchers now say that drinking gallons of orange juice and popping vitamin pills may not be a guarantee that you will live longer.

Chemical sealant - poloxamer 188 can repair damage to cardiac muscle cell membrane

A common chemical used in the manufacturing and pharmaceutical industries can repair damage to cardiac muscle cell membranes and prevent heart failure in mice with the genetic mutation that causes Duchenne muscular dystrophy, according to scientists at the University of Michigan Medical School.

Ethical guidelines suggested for stem cell research in primates

Before conducting research that involves putting human stem cells into the brains of nonhuman primates such as monkeys or apes, scientists and oversight committees should consider a series of ethical criteria, according to a policy paper released in the July 15 issue of Science.

Nerve cells can also release neurotransmitters outside of synapses

Every neurobiology textbook invariably states that nerve cells communicate with each other through synapses, the specialized cell-cell contacts found at the end of the cells' threadlike extensions. In the journal Science, researchers at the Salk Institute for Biological Sciences and the University of California at San Diego report that nerve cells, or neurons, may not have to rely on traditionally defined synapses to "talk" to each other.

New molecular insights may one day lead to opportunities to stave off old age

Delving deep into the molecular subtleties of a strain of mice engineered to age rapidly, scientists have found that an accumulation of genetic mutations prompts a cascade of programmed cell death that seems to underpin the aging process.

NIPA levels act as switch regulating cell division

Cells control mitosis (cell division) by assembling a biochemical switch to block it or by disassembling the switch to trigger it, according to investigators at St. Jude Children's Research Hospital and the Technical University of Munich.

Lipid helps cell wall protein fold into proper shape

A protein that provides a vital passage through a bacterium's outer cell wall will misfold and malfunction if that wall is built of the 'wrong' material, scientists at The University of Texas Medical School at Houston report in a finding that has long-term implications for understanding diseases caused by misfolded proteins such as cystic fibrosis, Alzheimer's disease, and mad cow disease.

PGE2 may be a target for Celebrex therapy

A product produced by lung cancer tumors fuels the cells that suppress immune function in patients and may be a target for Celebrex therapy, giving oncologists another weapon to fight cancer, according to a study by researchers at UCLA's Jonsson Cancer Center.

Scientists have begun to clarify how one of the body's molecules controls the trafficking of T cells through the blood

...lymph nodes and on to tissues to fight infection -- a crucial response that sometimes goes awry, attacking the body's own tissues and causing autoimmune diseases.

Novel treatment for ovarian cancer

The Tulane University Section of Hematology and Medical Oncology is investigating a novel treatment for ovarian cancer by using intravenous Ontak to deplete harmful cells that inhibit the body's natural immune response to fight cancer. Ovarian cancer is the fifth leading cancer killer of women in the United States.

New compound ruboxistaurin may decrease vision loss in diabete

A multicenter international study chaired by a Joslin Diabetes Center investigator and reported in the July issue of the American Diabetes Association's journal Diabetes brings hopeful news to the 18 million people in the United States -- and millions more worldwide -- with type 1 or type 2 diabetes.

Novel way in which the brain size of developing mammals may be regulated

Howard Hughes Medical Institute researchers have discovered a novel way in which the brain size of developing mammals may be regulated. They have identified a signaling pathway that controls the orientation in which dividing neural progenitor cells are cleaved during development.

Experts discuss use of human stem cells in ape and monkey brains

An expert panel of stem cell scientists, primatologists, philosophers and lawyers has concluded that experiments implanting, or grafting, human stem cells into non-human primate brains could unintentionally shift the moral ground between humans and other primates.

A systematic search through human genes

...has begun at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany. Working within the MitoCheck consortium that includes 10 other institutes throughout Europe, the EMBL scientists will silence all human genes, one-by-one, to find those involved in cell division (mitosis) and to answer fundamental questions of how cell division is regulated.
