Findings could pave the way for more effective tissue repair treatments Scientists have discovered how cells detect tissue damage and modify their repair properties accordingly. The findings, published today [6 October] in the journal Developmental Cell, could open up new opportunities for improving tissue repair in patients following illness or surgery. The Wellcome Trust-funded study, led by biochemists at the University of Bristol, examined the signaling process in damaged tissue...

A protein critical in heart development may also play a part in colon cancer progression. Research led by investigators from Vanderbilt-Ingram Cancer Center and the Vanderbilt Eye Institute suggests that the protein BVES (blood vessel endocardial substance) — which also is key in regulating corneal cells — may be a therapeutic target for halting colon cancer metastasis. The study, appearing in the October issue of the Journal of Clinical Investigation, further suggests that...

(Ivanhoe Newswire) -- Stroke is a leading cause of long-term disability and death in the United States. A team of researchers has discovered a way to exploit one of the brain's self-repair mechanisms to protect nerve cells and enhance brain repair in rodent models of stroke. The authors suggest that this approach could provide a nontoxic treatment for stroke. The most common form of stroke (ischemic stroke) occurs when a blood vessel that brings oxygen and nutrients to the brain becomes...

When the human genome project produced a map of human genes, the number of genes in humans turned out to be relatively small, approximately the same number as in primitive nematode worms. The difference in complexity between human and primitive organisms results from the ways in which the functions of genes are elaborated, rather from just the number of genes. Boston University School of Medicine (BUSM) researchers are showing how heparan sulfate, a carbohydrate that is expressed on the...

Scientists close in on molecular moves that let tumor cells act as stowaways in lymphatic system Cancer has a mighty big bag of tricks that it uses to evade the body's natural defense mechanisms and proliferate. Among those tricks is one that allows tumor cells to turn the intricate and extensive system of lymphatic vessels into something of a highway to metastasis. Yet research unveiled this week may aid in the development of therapeutics that will put the brakes on such cancer spread, and...

A molecule that lies dormant until it encounters a cancer cell, then suddenly activates and rouses the body's immune system to fight cancer cells directly, marks the latest step in scientists' efforts to tap the body's own resources to fight the disease. The developers of the technology at the University of Rochester Medical Center dub it the "Pacman strategy" because it hinges upon molecular machines produced in abundance by tumors to chew through and gobble up particular chains of...

Blood-vessel cells can combat aggressive tumors, helping to prevent them from spreading through the body, new study finds MIT scientists have discovered that cells lining the blood vessels secrete molecules that suppress tumor growth and keep cancer cells from invading other tissues, a finding that could lead to a new way to treat cancer. Elazer Edelman, professor in the MIT-Harvard Division of Health Sciences and Technology (HST), says that implanting such cells adjacent to a patient's tumor...

Mindin has an indispensable role in both innate and adaptive immunity. A research group in China investigated regulation of mindin expression and the signaling pathway involved. mRNA expression of mindin was upregulated during dextran sulfate sodium induced mouse intestinal inflammation. Stimulation with CpG-ODN (a known TLR-9 ligand) induced upregulation of mindin expression in RAW 264.7 cells and significantly increased the NF-ÃŽºB-luciferase activity in vitro. Body of...


Word of the Day
omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
'Omphalos' comes from the ancient Greek.
