Atpif1 gene regulates heme synthesis in red blood cell formation

Scientists at the University of Georgia, Harvard Medical School and the University of Utah have discovered a new gene that regulates heme synthesis in red blood cell formation. Heme is the deep-red, iron-containing component of hemoglobin, the protein in red blood cells responsible for transporting oxygen in the blood.

XJB-5-131 compound suppresses symptoms of Huntington's in mice

There's new hope in the fight against Huntington's disease. A group of researchers that includes scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have designed a compound that suppresses symptoms of the devastating disease in mice.

Novel method can determine how ready acute myeloid leukemia cells are to die

Researchers at Dana-Farber Cancer Institute have developed a novel method for determining how ready acute myeloid leukemia (AML) cells are to die, a discovery that may help cancer specialists to choose treatments option more effectively for their patients who have AML.

New technique can identify cell-secreted proteins

Researchers from North Carolina State University have developed a new technique to identify the proteins secreted by a cell. The new approach should help researchers collect precise data on cell biology, which is critical in fields ranging from zoology to cancer research.

Researchers use nanoparticles to deliver drugs to mitochondria within cells

Nanoparticles have shown great promise in the targeted delivery of drugs to cells, but researchers at the University of Georgia have refined the drug delivery process further by using nanoparticles to deliver drugs to a specific organelle within cells.

Humans could learn from how plants handle stress

Humans could learn from how plants handle stress. Federica Brandizzi, Michigan State University plant biologist, is using a grant from the National Institutes of Health to study how plants overcome stress as they grow. These pathways used to overcome stress are a key to growth. Without them plants, and animals, would die.

Stanford and MBL scientists win prestigious Lasker Awards

Scientists who invented new ways to study how "cargo" is moved within cells and, as a result, discovered a new biological motor protein, kinesin, at the Marine Biological Laboratory (MBL) in Woods Hole, Mass., have received the prestigious 2012 Lasker Award for Basic Medical Research, the Albert and Mary Lasker Foundation announced today.

Stowers investigators define factors that regulate size of cellular fat pools

As the national waistline expands, so do pools of intra-cellular fat known as lipid droplets. Although most of us wish our lipid droplets would vanish, they represent a cellular paradox: on the one hand droplets play beneficial roles by corralling fat into non-toxic organelles. On the other, oversized lipid droplets are associated with obesity and its associated health hazards.

ABCD4 and CblF proteins responsible for hereditary vitamin B12 deficiency

Vitamin B12 is vital for cell division, the synthesis of red blood cells and the functioning of the nervous system. Unable to produce the vitamin itself, the human body has to obtain it via animal proteins. So far it has been known that on its way into the cell vitamin B12 is absorbed by little organelles, so-called lysosomes. From there, the vitamin enters the cell interior with the aid of the transport protein CblF, which was discovered by the same research team three years ago.

Abnormalities in mitochondrial length promote development of neurodegenerative diseases

Goldilocks was on to something when she preferred everything "just right." Harvard Medical School researchers have found that when it comes to the length of mitochondria, the power-producing organelles, applying the fairy tale's mantra is crucial to the health of a cell. More specifically, abnormalities in mitochondrial length promote the development of neurodegenerative diseases such as Alzheimer's.

Study highlights Nek9 protein as decisive factor in cell division

A study by the Institute for Research in Biomedicine (IRB Barcelona) and the Center for Genomic Regulation (acronym in Catalan CRG) highlights the protein Nek9 as a decisive factor in cell division, a fundamental process for both the development of an organism and tissue maintenance.

MitoTarget Project and neurodegenerative diseases: an interview with Rebecca Pruss, Ph.D., CSO of Trophos

The MitoTarget Project was a project funded by the European Commission, under their FP7 programme. It was funding for a call published in 2007.

Researchers discover genetic cause of type VII mucopolysaccharidosis in Brazilian Terriers

The genetics research group led by Professor Hannes Lohi, based at the University of Helsinki and the Folkh-lsan Research Center, has, in collaboration with Adjunct Professor Kirsi Sainio's research group, discovered the cause of a life-threatening skeletal disorder affecting Brazilian Terriers. The disease is caused by a mutation in the GUSB gene.

Researchers verify role of alpha-synuclein aggregates in vivo

Using a two-photon microscope capable of peering deep within living tissue, researchers at the University of California, San Diego School of Medicine have found new evidence that alpha-synuclein protein build-up inside neurons causes them to not only become "leaky," but also to misfire due to calcium fluxes.

Study focuses on interaction between two key proteins involved in apoptosis

A promising method for promoting programmed cell death (apoptosis) developed by researchers at the Hebrew University of Jerusalem and the Weizmann Institute of Science paves the way for a possible novel therapy to target cancer cells.

PGC-1alpha and TFEB provide two new therapeutic targets for Huntington's disease

In a paper published in the July 11 online issue of Science Translational Medicine, researchers at the University of California, San Diego School of Medicine have identified two key regulatory proteins critical to clearing away misfolded proteins that accumulate and cause the progressive, deadly neurodegeneration of Huntington's disease.
