Perturbing DISC1 gene could help researchers treat mental illness, says study

Scientists have long eyed mutations in a gene known as DISC1 as a possible contributor to schizophrenia and mood disorders, including depression and bipolar disorder. Now, new research led by Johns Hopkins researchers suggests that perturbing this gene during prenatal periods, postnatal periods or both may have different effects in mice, leading to separate types of brain alterations and behaviors with resemblance to schizophrenia or mood disorders.

Scientists determine how RNAi, a biological response to RNA, can regulate gene expression

A team of scientists at Cold Spring Harbor Laboratory (CSHL) has determined a hierarchical set of criteria that explain how the molecular precursors of gene-regulating small RNAs are sorted by the cellular machinery.

Vitamin C reverses accelerated aging due to Werner's syndrome

A new research discovery published in the January 2010 print issue of the FASEB Journal suggests that treatments for disorders that cause accelerated aging, particularly Werner's syndrome, might come straight from the family medicine chest. In the research report, a team of Canadian scientists show that vitamin C stops and even reverses accelerated aging in a mouse model of Werner's syndrome, but the discovery may also be applicable to other progeroid syndromes.

Scientists develop mucus-penetrating biodegradable nanoparticles to deliver drugs over time

Johns Hopkins University researchers have created biodegradable nanosized particles that can easily slip through the body's sticky and viscous mucus secretions to deliver a sustained-release medication cargo.

Elusive human protein outsmarted

A team of researchers is being recognized for devising a new way to study a human protein that long has evaded close scrutiny by scientists investigating its role in the communication of important genetic messages inside a cell's nucleus to workhorse molecules found elsewhere.

Study identifies novel factor that causes Alzheimer's disease

Inheritance of an extra copy of the gene- β -amyloid precursor protein, APP, in individuals with Down syndrome leads to the inevitable development of early onset Alzheimer's disease, known to be linked to the deposition of Amyloid β peptide or Aβ in the brain.

Transcription factor promotes stem cell proliferation to repair tissue damage

The master regulator of muscle differentiation, MyoD, functions early in myogenesis to help stem cells proliferate in response to muscle injury, according to researchers at Case Western Reserve University. The study appears online Jan. 4 in the Journal of Cell Biology (www.jcb.org).

US-German team studies genome mutations

"While the long term effects of genome mutations are quite well understood, we did not know how often new mutations arise in the first place," said Detlef Weigel, director at the Max Planck Institute in Germany. It is routine today to compare the genomes of related animal or plant species.

Scientists discover a new family of giant virus

After Mimivirus, Mamavirus and the virophage, the group of giant viruses now has a new member called Marseillevirus. Discovered in an amoeba by the team led by Didier Raoult at the Unité de Recherche sur les Maladies Infectieuses et Tropicales Emergentes research group (CNRS/Université Aix-Marseille 2), a description of this new virus was published this week on the website of the Proceedings of the National Academy of Sciences (PNAS).

Gene mutation that decreases flesh-eating disease discovered by scientists

Scientists at The Methodist Hospital Research Institute in Houston recently discovered a simple gene mutation that decreases the chance people will get a flesh-eating disease called necrotizing fasciitis. Further, they proved that inactivating this section of the gene lessens the devastating disease in humans.

Advances in development of “lipidoid” formulations for systemic delivery of RNAi therapeutics

Alnylam Pharmaceuticals, Inc., a leading RNAi therapeutics company, and collaborators from the David H. Koch Institute for Integrative Research at the Massachusetts Institute of Technology (MIT) today announced the publication of new data in the journal Proceedings of the National Academy of Sciences (PNAS) describing further advancements in discovery and development of novel “lipidoid” formulations for the systemic delivery of RNAi therapeutics.

Study explains how semaphorin gene regulates synapse formation

By combining a research technique that dates back 136 years with modern molecular genetics, a Johns Hopkins neuroscientist has been able to see how a mammal's brain shrewdly revisits and reuses the same molecular cues to control the complex design of its circuits.

TSC proteins regulate Notch activity

Two independent teams of researchers have identified a role for enhanced activation of the signaling protein Notch in tumors characterized by inactivation of either the TSC1 or the TSC2 protein. As indicated by Warren Pear, at the University of Pennsylvania, Philadelphia, in an accompanying commentary, these data provide a rationale for testing whether Notch inhibitors are of benefit to those with TSC-associated tumors.

Study suggests genetic variations predispose African-Americans to diabetes

For years, scientists have tried to determine the basis for discrepancies between race and the predisposition for development of diseases such as type II diabetes and cardiovascular disease. Could factors such as differences in lifestyle or access to health care play a role, or is there something else in play?
