(Press-News.org) Hereditary spastic paraplegias (HSPs) are a group of inherited neurodegenerative disorders characterized by progressive weakness and spasticity (stiffness) of the legs. Mutations in more than 30 genes have been linked to HSPs. A team of researchers — led by Stephan Züchner, at the University of Miami Miller School of Medicine, Miami; Evan Reid, at the University of Cambridge, United Kingdom; and Antonio Orlacchio, at the Centro Europeo di Ricerca sul Cervello–Istituto di Ricovero e Cura a Carattere Scientifico Santa Lucia, Italy — has now associated mutations in the gene reticulon 2 with hereditary spastic paraplegia type 12. In addition to identifying a new HSP-associated gene, the team was able to uncover how the mutations in reticulon 2 are likely to cause neurodegeneration, providing new insight into this diverse group of inherited disorders.

EDITOR'S PICK: Genetic and mechanistic basis for rotor syndrome uncovered
The main symptom of Rotor syndrome is jaundice caused by a buildup of a substance known as conjugated bilirubin. Bilirubin is a yellow substance generated in large quantities when the body recycles red blood cells. It is conjugated in the liver to make it soluble in water so that it can be cleared from the body. Although Rotor syndrome is known to be a genetic disorder, it is not known which genes are involved. However, a team of researchers — led by Alfred Schinkel, at The Netherlands Cancer Institute, ...
TGen researchers map potential genetic origins, pathways of lung cancer in nonsmokers
2012-01-09
SAN DIEGO -- Researchers at the Translational Genomics Research Institute (TGen) have begun to identify mutations and cellular pathway changes that lead to lung cancer in never-smokers — a first step in developing potential therapeutic targets.
"This is the starting point. We certainly have a lot of pathways and gene expression alterations that we're going to be very interested in confirming and looking at in larger cohorts of patients," said Dr. Timothy G. Whitsett, Senior Postdoctoral Fellow in TGen's Cancer and Cell Biology Division.
Whitsett presented the findings ...

Tortoise species thought to be extinct still lives, genetic analysis reveals
2012-01-09
Dozens of giant tortoises of a species believed extinct for 150 years may still be living at a remote location in the Galápagos Islands, a genetic analysis conducted by Yale University researchers reveals.
The analysis, published Jan. 9 in the journal Current Biology, suggests that direct descendants of at least 38 purebred individuals of Chelonoidis elephantopus live on the volcanic slopes of the northern shore of Isabela Island — 200 miles from their ancestral home of Floreana Island, where they disappeared after being hunted by whalers.
"This is not just an academic ...

Nicotine replacement therapies may not be effective in helping people quit smoking
2012-01-09
Boston, MA – Nicotine replacement therapies (NRTs) designed to help people stop smoking, specifically nicotine patches and nicotine gum, do not appear to be effective in helping smokers quit long-term, even when combined with smoking cessation counseling, according to a new study by researchers at Harvard School of Public Health (HSPH) and the University of Massachusetts Boston.
The study appears January 9, 2012 in an advance online edition of Tobacco Control and will appear in a later print issue.
"What this study shows is the need for the Food and Drug Administration, ...

New 'real-world' reassuring data from the SCAAR registry
2012-01-09
A registry -which includes every patient in Sweden having percutaneous coronary intervention (PCI) for the treatment of acute and stable coronary artery disease- has found that PCI implantations using a new generation of drug-eluting stents is associated with lower rates of relapse (restenosis), stent thrombosis and subsequent mortality than older generation drug-eluting stents and bare-metal stents.(1)
The findings, from the Swedish Coronary Angiography and Angioplasty Registry (SCAAR), reported in the European Heart Journal, represent the outcome of treatment in a large ...
'Extinct' for 150 years, an iconic Galápagos giant tortoise species lives
2012-01-09
Representatives of a giant tortoise species that had apparently been driven to extinction by humans more than 150 years ago must be alive today, if in very small numbers. Researchers reporting in the January 10 issue of Current Biology, a Cell Press publication, have come to this conclusion based on the "genetic footprints" of the long-lost species Chelonoidis elephantopus in the DNA of their hybrid sons and daughters.
"To our knowledge, this is the first report of the rediscovery of a species by way of tracking the genetic footprints left in the genomes of its hybrid ...
