Tbx18 gene directs conversion of cardiomyocytes to genuine pacemaker cells

Cedars-Sinai Heart Institute researchers have reprogrammed ordinary heart cells to become exact replicas of highly specialized pacemaker cells by injecting a single gene (Tbx18)-a major step forward in the decade-long search for a biological therapy to correct erratic and failing heartbeats.

Germ cell removal may promote longevity

The gonad is well known to be important for reproduction but also affects animal life span. Removal of germ cells - the sperm and egg producing cells - increases longevity of the roundworm Caenorhabditis elegans. However, the underlying molecular mechanisms were a mystery. Now scientists at the Cologne-based Max Planck Institute for Biology of Ageing, have discovered that germ cell removal flips a "molecular switch" that extends the life span by using components of a "developmental clock".

PRSS3 enzyme linked to aggressive prostate cancer

Researchers at Mayo Clinic's campus in Florida have identified an enzyme specifically linked to aggressive prostate cancer, and have also developed a compound that inhibits the ability of this molecule to promote the metastatic spread of the cancer.

Study investigates muscle weakness in mouse model of Down syndrome

It is well known that people with Down syndrome (DS) suffer from marked muscle weakness. Even the simple tasks of independent living, such as getting out of a chair or climbing a flight of stairs, can become major obstacles. This can reduce the quality of life for those with DS and lead to a loss of independence. Now, a new study sheds light on some of the suspected causes of muscle weakness.

Vero system can treat patients with recent diagnoses of metastatic cancer

University of Florida radiation oncologists are using a sophisticated medical device to treat patients who have recent diagnoses of metastatic cancer, where the disease has started to spread from one part of the body to another.

Injecting LECT2 may protect against bacterial sepsis

Failure to launch an adequate immune response may be at the root of septic shock, according to a study published in The Journal of Experimental Medicine on December 17th.

New MIT technology may help make cancer biomarker detection much easier

Finding ways to diagnose cancer earlier could greatly improve the chances of survival for many patients. One way to do this is to look for specific proteins secreted by cancer cells, which circulate in the bloodstream. However, the quantity of these biomarkers is so low that detecting them has proven difficult.

University of North Carolina awards 13th Perl prize to two NTNU-Trondheim scientists

The University of North Carolina at Chapel Hill has awarded the 13th Perl-UNC Neuroscience prize jointly to Edvard and May-Britt Moser at the Norwegian University of Science and Technology (NTNU-Trondheim) in Trondheim, Norway.

Researchers identify possible heredity mechanism that predisposes children to ALL

Researchers at the Sainte-Justine University Hospital Center and the University of Montreal have found a possible heredity mechanism that predisposes children to acute lymphoblastic leukemia (ALL), the most common type of blood cancer in children. According to their findings published in Genome Research, the presence of a genetic defect in the egg or sperm from which children having ALL arise may be a prerequisite for the disease to develop.

Scientists develop new nanotechnology to capture, release tumor cells that circulate in bloodstream

Scientists from the RIKEN Advanced Science Institute in Japan and University of California Los Angeles report a new nanoscale Velcro-like device that captures and releases tumor cells that have broken away from primary tumors and are circulating in the bloodstream.

Loading up on snack foods may increase cancer risk in individuals with Lynch syndrome

A new analysis has found that loading up on snack foods may increase cancer risk in individuals with an inborn susceptibility to colorectal and other cancers. Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the study suggests that an eating pattern low in snack foods could help these individuals-who have a condition called Lynch syndrome-lower their risk.

New technique could help develop more-specific, cell-based immune therapies for cancer

A team led by Michel Sadelain, MD, PhD, Director of the Center for Cell Engineering at Memorial Sloan-Kettering Cancer Center, has shown for the first time the effectiveness of a new technique that could allow the development of more-specific, cell-based immune therapies for cancer.

Paternal exposure to cocaine can impair gene expression and behavior in their offspring

Research from the Perelman School of Medicine at the University of Pennsylvania and Massachusetts General Hospital (MGH) reveals that sons of male rats exposed to cocaine are resistant to the rewarding effects of the drug, suggesting that cocaine-induced changes in physiology are passed down from father to son.

Blocking single tiny blood vessel in the brain can harm neural tissue and even alter behavior

Blocking a single tiny blood vessel in the brain can harm neural tissue and even alter behavior, a new study from the University of California, San Diego has shown. But these consequences can be mitigated by a drug already in use, suggesting treatment that could slow the progress of dementia associated with cumulative damage to miniscule blood vessels that feed brain cells.

Immunohistochemistry reliable in identifying ALK rearrangement: Study

Favorable results have led to crizotinib gaining approval for the treatment of advanced stage ALK-positive non-small cell lung cancer (NSCLC) in Japan, the United States, Canada, and several other countries in Europe and Asia.

New model of how the capsid of viruses assembles

A new model of the how the protein coat (capsid) of viruses assembles, published in BioMed Central's open access journal BMC Biophysics, shows that the construction of intermediate structures prior to final capsid production (hierarchical assembly) can be more efficient than constructing the capsid protein by protein (direct assembly).
