Researchers discover small DNA sequence that drives GATA2 protein

The protein GATA2 is known as a "master regulator" of blood cell development. When a mutation occurs in the gene that makes GATA2, serious blood diseases such as acute myeloid leukemia can result.

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.

New sequencing approach can provide more effective method of BRCA1/2 mutational analysis

Individuals with mutations in BRCA1 and BRCA2 genes have a significantly higher risk of developing breast and ovarian cancers. Families at risk have been seeking genetic testing and counseling based on their mutation carrier status, but the standard method of direct sequencing is labor-intensive, costly, and it only targets a part of the BRCA1 and BRCA2 genes.

Researchers identify six genes with driving mutations in melanoma

It's been a burning question in melanoma research: Tumor cells are full of ultraviolet (UV)-induced genetic damage caused by sunlight exposure, but which mutations drive this cancer? None have been conclusively tied to melanoma. The sheer abundance of these passenger mutations has obscured the search for genetic driver mutations that actually matter in melanoma development and progression.

Osteoarthritis gene tic markers identified

Scientists have used data from the Arthritis Research UK Osteoarthritis Genetics study to identify five gene loci significantly associated with the development of the disease.

Gender link discovered for colorectal cancer

Researchers have identified three new colorectal cancer risk loci, including one on the X-chromosome, bringing the total number of independent loci associated with the disease to 20.

MicroRNA-3151 a new independent prognostic marker for acute leukemia

A study has identified microRNA-3151 as a new independent prognostic marker in certain patients with acute leukemia. The study involves patients with acute myeloid leukemia and normal-looking chromosomes.

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.

Greenwood launches Syndromic Autism 62-Gene Panel

RainDance Technologies, Inc., the Digital Biology Company, today announced that Greenwood Genetic Center has commercially launched its Syndromic Autism 62-Gene Panel which was built for use on RainDance's picodroplet-based targeted sequencing platform.

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.

Biologists develop radar to track ADAR's RNA editing activity in neurons

To track what they can't see, pilots look to the green glow of the radar screen. Now biologists monitoring gene expression, individual variation, and disease have a glowing green indicator of their own: Brown University biologists have developed a "radar" for tracking ADAR, a crucial enzyme for editing RNA in the nervous system.

DNA sequencing identifies new altered genes that drive CLL

The most comprehensive search to date of DNA abnormalities in chronic lymphocytic leukemia (CLL) has unearthed several new altered genes that drive this common blood cancer, a finding that could potentially help doctors predict whether an individual patient's disease will progress rapidly or remain indolent for years, say scientists from Dana-Farber Cancer Institute and the Broad Institute.

Study: Genes that are active in brain are transcribed with special mechanism

Knowledge about the development of the nervous system is of the greatest importance for us to understand the function of the brain and brain disorders. Researchers at Uppsala University have examined the key step when genes are read and found that genes that are active in the brain are transcribed with a special mechanism.

Cancer cells maintain rapid proliferation due to PK-M2 enzyme

Cancer cells maintain their life-style of extremely rapid growth and proliferation thanks to an enzyme called PK-M2 (pyruvate kinase M2) that alters the cells' ability to metabolize glucose - a phenomenon known as the Warburg effect.

Scientists uncover novel mechanism linked to Spinocerebellar ataxia 7

A team of scientists, led by researchers at the University of California, San Diego School of Medicine, have uncovered a novel mechanism regulating gene expression and transcription linked to Spinocerebellar ataxia 7, an inherited neurological disorder.

Rsearchers define new step that controls programmed cell death in cancer cells

When cells find themselves in a tight spot, the cell cycle regulator p21 halts the cell cycle, buying cells time to repair the damage, or if all else fails, to initiate programmed cell death.

Loss of SKIP sensitizes cancer cells to apoptotic effects of DNA damage-inducing anticancer drugs

When cells find themselves in a tight spot, the cell cycle regulator p21 halts the cell cycle, buying cells time to repair the damage, or if all else fails, to initiate programmed cell death. In contrast to other stress-induced genes, which dispense with the regular transcriptional entourage, p21Cip1 still requires SKIP, a transcription elongation factor that also helps with the editing of transcripts, to be expressed, found researchers at the Salk Institute for Biological Studies.

Scientists detail role of TDP-43 in ALS pathology

Amyotrophic lateral sclerosis, known as ALS or more popularly, Lou Gehrig's disease, is a notorious neurodegenerative condition characterized by the progressive deterioration of brain and spinal cord neurons, resulting in the gradual but catastrophic loss of muscle control and ultimately, death.

Whites with mutations more likely to be susceptible to cocaine abuse

Nearly one in five whites could carry a genetic variant that substantially increases their odds of being susceptible to severe cocaine abuse, according to new research.
