Researchers link plasticity related gene-1 to lipid phosphates

In mice that are missing a protein found only in the brain, neural signals "go crazy," leaving the animals with epileptic seizures from a young age, researchers have found. The report in the September 18th Cell, a Cell Press publication, details what it is that happens when the protein encoded by plasticity related gene-1 (PRG-1) gets lost, revealing an important fine-tuning mechanism for brain function.

Insulin metabolism regulates body's internal clock

While scientists have known for several years that our body's internal clock helps regulate many biological processes, researchers have found that the reverse is also true: Many common biological processes - including insulin metabolism - regulate the clock, according to a new study by investigators at the University of Pennsylvania School of Medicine, the Genomics Institute of the Novartis Research Foundation, and the University of California at San Diego.

Research reveals that iPSCs similar to embryonic stem cells

A team of researchers from the University of California, San Diego School of Medicine and the Salk Institute for Biological Studies in La Jolla have developed a safe strategy for reprogramming cells to a pluripotent state without use of viral vectors or genomic insertions. Their studies reveal that these induced pluripotent stem cells (iPSCs) are very similar to human embryonic stem cells, yet maintain a "transcriptional signature." In essence, these cells retain some memory of the donor cells they once were.

PSC activation mechanisms help develop novel therapeutic approaches for pancreatic fibrosis

Fibrosis is a key feature of chronic pancreatitis and pancreatic cancer. The extensive deposition of extracellular matrix proteins fosters the development of an exocrine and endocrine organ insufficiency, and accelerates progression of the tumour. Pancreatic stellate cells (PSC) are the principal effector cells in pancreatic fibrosis. They are activated by profibrogenic mediators, which include, for example, cytokines and ethanol metabolites.

Research reveals that reactive oxygen inhibition can limit cancer cell invasion

Researchers at the Burnham Institute for Medical Research (Burnham) have discovered that reactive oxygen species, such as superoxide and hydrogen peroxide, play a key role in forming invadopodia, cellular protrusions implicated in cancer cell migration and tumor metastasis.

Protein aggregation is linked to many conformational diseases

Researchers at the Department of Biochemistry and Molecular Biology of Universitat Autònoma de Barcelona (UAB) have revealed the process by which proteins with a tendency to cause conformational diseases such as amyotrophic lateral sclerosis, familial amyloidotic polyneuropathy, familial amyloidotic cardiomyopathy, etc. finally end up causing them.

Guide reveals that non-smokers require different treatment for lung cancer

A committee of scientists led by Johns Hopkins investigators has published a new guide to the biology, diagnosis and treatment of lung cancer in never-smokers, fortifying measures for what physicians have long known is a very different disease than in smokers.

Link between a key molecular player and human chromosomal birth defects established

Using yeast genetics and a novel scheme to selectively remove a single protein from the cell division process called meiosis, a cell biologist at The Florida State University found that when a key molecular player known as Pds5 goes missing, chromosomes fail to segregate and pair up properly, and birth defects such as Down syndrome can result.

Successful eye surgery involves eyetooth implant in eye

Blind for nine years, Sharron “Kay” Thornton has just regained her sight through a first-in-the-U.S. surgical procedure at Bascom Palmer Eye Institute at the University of Miami Miller School of Medicine. The procedure -- modified osteo-odonto-keratoprosthesis (MOOKP) -- implanted her eyetooth in her eye, as a base to hold a prosthetic lens.

Researchers discover HIV Nef protein's role in cell mobility inhibition

In order to be able to ward off disease pathogens, immune cells must be mobile and be able to establish contact with each other. The working group around Professor Dr. Oliver Fackler in the Virology Department of the Hygiene Institute of the Heidelberg University Hospital has discovered a mechanism in an animal model revealing how HIV, the AIDS pathogen, cripples immune cells: Cell mobility is inhibited by the HIV Nef protein.
