Scripps Florida designs new compound that shows promise against tremor ataxia syndrome

Scientists on the Florida campus of The Scripps Research Institute have designed a compound that shows promise as a potential therapy for one of the diseases closely linked to fragile X syndrome, a genetic condition that causes mental retardation, infertility, and memory impairment, and is the only known single-gene cause of autism.

LIN28 protein can bind directly to thousands of messenger RNAs

A study led by researchers at the UC San Diego Stem Cell Research program and funded by the California Institute for Regenerative Medicine (CIRM) looks at an important RNA binding protein called LIN28, which is implicated in pluripotency and reprogramming as well as in cancer and other diseases.

Investigators discover biological explanation for why low levels of oxygen advance SMA symptoms

Investigators at Nationwide Children's Hospital may have discovered a biological explanation for why low levels of oxygen advance spinal muscular atrophy (SMA) symptoms and why breathing treatments help SMA patients live longer. The findings appear in Human Molecular Genetics.

Fluorescent molecules 'tag' DNA and monitor looping process

In a new study, UT Dallas researchers outline how they used fluorescent molecules to "tag" DNA and monitor a process called DNA looping, a natural biological mechanism involved in rearranging genetic material in some types of cells.

NeoGenomics introduces new molecular assay that detects SF3B1 gene mutations

NeoGenomics, Inc., a leading provider of cancer-focused genetic testing services, announced today that it has validated and launched the first molecular assay for clinical use in the United States that detects mutations in the SF3B1 gene (splicing factor 3b, subunit 1).

Anacardic acid can rescue some ALS phenotypes in vitro

A research group at the Center for iPS Cell Research and Application (CiRA) at Japan's Kyoto University has successfully recapitulated amyotrophic lateral sclerosis (ALS)-associated abnormalities in motor neurons differentiated from induced pluripotent stem cells (iPSCs) obtained from patients with familial ALS, a late-onset, fatal disorder which is also known for Lou Gehrig's disease. In a drug screening assay using the disease model, the team further found that the chemical compound anacardic acid can rescue some ALS phenotypes in vitro.

Novel genomic sequencing method can help conduct in-depth analysis of single cells

Only by viewing a Georges Seurat painting at close range can you appreciate the hidden complexities of pointillism - small, distinct dots of color applied to form an image from a distance. Similarly, biologists and geneticists have long sought to analyze profiles of genes at the single cell level but technology limitations have only allowed a view from afar.

DRCRF names 21 new Damon Runyon Fellows

The Damon Runyon Cancer Research Foundation, a non-profit organization focused on supporting innovative early career researchers, named 21 new Damon Runyon Fellows at its spring Fellowship Award Committee review.

New signal transduction pathway might be fruitful target for cancer drugs

Researchers at the University of California, San Diego School of Medicine have uncovered a new signal transduction pathway specifically devoted to the regulation of alternative RNA splicing, a process that allows a single gene to produce or code multiple types of protein variants. The discovery, published in the June 27, 2012 issue of Molecular Cell, suggests the new pathway might be a fruitful target for new cancer drugs.

Inhibiting IRE1α-XBP1 pathway impacts survival of myeloma cells

Results published in Blood, the official journal of the American Society of Hematology, confirm that inhibition of the IRE1α-XBP1 pathway impacts the survival of myeloma cells, suggesting a promising therapeutic option in multiple myeloma.

Gene function preserved despite structural differences in the DNA

Chloroplasts, the plant cell's green solar power generators, were once living beings in their own right. This changed about one billion years ago, when they were swallowed up but not digested by larger cells. Since then, they have lost much of their autonomy.

RNA binding motif protein 20 regulates titin splicing

Cardiomyopathy comprises a deterioration of the heart muscle that affects the organ's ability to efficiently pump blood through the body. Previously researchers have tied forms of the disease to the alternative splicing of titin, a giant protein that determines the structure and biomechanical properties of the heart, but the molecular mechanism remained unknown.

Study reveals central role played by DBIRD protein complex in gene transcription

In a study published this week in the journal Nature, researchers at the University of Liège's GIGA Unit, together with English and German teams, reveal the central role played by a protein complex, unknown up to now, in gene transcription.

Molecular ticket determines RNA's destination and speed inside egg cell

Like any law-abiding train passenger, a molecule called oskar RNA carries a stamped ticket detailing its destination and form of transport, scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have found.

New, freely available Web-based program helps predict effect of mutations on mRNA splicing

In a brief paper in the journal Bioinformatics, Brown University researchers describe a new, freely available Web-based program called Spliceman for predicting whether genetic mutations are likely to disrupt the splicing of messenger RNA, potentially leading to disease.

Scientists design compounds that act against myotonic dystrophy type 1 RNA

While RNA is an appealing drug target, small molecules that can actually affect its function have rarely been found. But now scientists from the Florida campus of The Scripps Research Institute have for the first time designed a series of small molecules that act against an RNA defect directly responsible for the most common form of adult-onset muscular dystrophy.

New kind of on-off switch for cortisol release in the brain discovered

After we sense a threat, our brain center responsible for responding goes into gear, setting off a chain of biochemical reactions leading to the release of cortisol from the adrenal glands.

Study describes how multiple RNA binding proteins cooperatively control genetic splicing code

Understanding how RNA binding proteins control the genetic splicing code is fundamental to human biology and disease - much like editing film can change a movie scene. Abnormal variations in splicing are often implicated in cancer and genetic neurodegenerative disorders.

Defect in neuronal RNA splicing process may contribute to neurological disease

A Jackson Laboratory research team led by Professor and Howard Hughes Medical Investigator Susan Ackerman, Ph.D., has discovered a defect in the RNA splicing process in neurons that may contribute to neurological disease.

Connection between Musashi1 and HuR proteins can lead to glioblastoma

Most research on glioblastoma development, a complicated tumor of the brain with a poor prognosis, has focused on the gene transcription level, but scientists suggest that post-transcriptional regulation could be equally or even more important.
