Cell signaling is vital for cells to communicate and coordinate their activities, not just in the human body, but in all organisms. There are thousands of signaling pathways, ranging from protein homeostasis to carcinogenesis and biofilm formation.

Scientists show that endothelial cells give rise to blood stem cells

Stem cell researchers at UCLA have proven definitively that blood stem cells are made during mid-gestational embryonic development by endothelial cells, the cells that line the inside of blood vessels.

Genetic breakdown in Fanconi anemia may have link to HPV-associated cancer

A genetic malfunction that causes DNA instability in people with the blood disorder Fanconi anemia may put them at high risk for squamous cell carcinomas linked to human papillomavirus (HPV), according to a study posted online ahead of print by Oncogene.

Reduced-calories and exercise can modify a postmenopausal woman's risk of breast cancer

Scientists at the University of Texas at Austin have identified pathways by which a reduced-calorie diet and exercise can modify a postmenopausal woman's risk of breast cancer.

Scientists establish completely new route to cancer development

CANCER RESEARCH UK scientists have linked cancer clues in faulty cells to provide a new route to cancer development, reveals a study published in Developmental Cell.

Discovery of key contributor to Alzheimer's disease process

Walter J. Lukiw, PhD, Associate Professor of Neuroscience and Ophthalmology at LSU Health Sciences Center New Orleans, is the lead author of a paper identifying, for the first time, a specific function of a fragment of ribonucleic acid (RNA), once thought to be no more than a byproduct, in regulating inflammation and the development of Alzheimer's disease.

New research sheds light on key trigger of embryonic stem cell differentiation

Clusters of mouse embryonic stem cells called embryoid bodies more closely approximate true embryos in organization and structure than previously thought, according to researchers at the Stanford University School of Medicine.

Human papillomavirus helps cervical and head and neck cancers resist treatment and grow and spread

The human papillomavirus (HPV) allows infected cervical and head and neck cancer cells to maintain internal molecular conditions that make the cancers resistant to therapy and more likely to grow and spread, resulting in a poor prognosis for patients, researchers with UCLA's Jonsson Cancer Center found.

Resveratrol shows promise for treating human alcoholic fatty liver disease

The accumulation of fat in the liver as a result of chronic alcohol consumption could be prevented by consuming resveratrol, according to a new study with mice. The research found that resveratrol reduced the amount of fat produced in the liver of mice fed alcohol and, at the same time, increased the rate at which fat within the liver is broken down.

Battling cancer at the single cell level

New research suggests that the identification and examination of key cell signaling events required for initiation and progression of cancer might be best accomplished at the single cell level. The research, published by Cell Press in the October issue of the journal Cancer Cell, provides new insight that may lead to better diagnosis and treatment of some complex cancers.

New rapid test for rare leukemia

A new twist on a well-known cell sorting technique may allow physicians to diagnose rare leukemias in hours instead of weeks, according to a study by researchers at the Stanford University School of Medicine and UC-San Francisco.

Universal gene signaling mechanism identified by UB molecular researchers

A novel gene signaling mechanism that controls whether a stem cell develops into its destined tissue or fails to differentiate and becomes cancer has been identified by researchers in the multi-laboratory Molecular and Structural Neurobiology and Gene Therapy Program based at the University at Buffalo.

Medulloblastoma originates in normal brain "stem" cells that turn malignant

An aggressive childhood brain tumor known as medulloblastoma originates in normal brain "stem" cells that turn malignant when acted on by a known mutant, cancer-causing oncogene, say researchers from Dana-Farber Cancer Institute and the University of California, San Francisco (UCSF).

Cannabinoid cell surface receptor plays a tumor-suppressing role in human colorectal cancer

CB1 is well-established for relieving pain and nausea, elevating mood and stimulating appetite by serving as a docking station for the cannabinoid group of signaling molecules. It now may serve as a new path for cancer prevention or treatment.

Laboratory and mouse studies show targeted drug blocks the growth of breast cancer cells that spread to the brain

Using laboratory and mouse models of human breast cancer, researchers have found that a small molecule capable of targeting specific proteins on the surface of breast cancer cells can inhibit the growth of breast cancer cells that migrate to the brain.

Designer diet for prostate cancer

Eating one or more portions of broccoli every week can reduce the risk of prostate cancer, and the risk of localised cancer becoming more aggressive.

Apollo acquisition boosts NZ biotech Symansis

New Zealand biotech Symansis has purchased Australian company Apollo Cytokine Research for A$500,000 (NZ$627,000) to build on its unique cell signaling science and fast track expansion into new international markets.

Discovery of possible new way to block inflammation in autoimmune disease

Researchers from the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), a part of the National Institutes of Health (NIH), have identified a promising new target for autoimmune disease treatment - a cell-surface receptor called DR3.

EntreMed receives new patent for 2-Methoxyestradiol analogs

EntreMed, Inc. has announced the issuance of U.S. Patent No. 7,371,741 covering analogs of 2- methoxyestradiol (2ME2).

Scientists demonstrate feasibility of preventing malaria parasite from becoming sexually mature

Researchers have demonstrated the possibility of preventing the human malaria parasite, Plasmodium falciparum, which is responsible for more than a million malaria deaths a year, from becoming sexually mature.

Researchers find multiple cancer genes cooperate to cause malignant cell transformation

Pinpointing new targets for cancer treatments is as difficult as finding a needle in a haystack, yet a University of Rochester team has discovered an entire novel class of genes they believe will lead to a greater understanding of cancer cell function and the next generation of effective and less harmful therapies for patients.
